Description

Technical Field

[0001] The present invention relates to the technical field of oil delivery hoses, and in particular to an enhanced oil delivery hose and an oil delivery system. Background Art

[0002] During offshore oil transportation operations, when the oil hose is connected to fixed equipment (including offshore oil tankers, single-point mooring equipment, and shore equipment, etc.), the pipe body floats on the sea surface, especially in high sea conditions, and is easily affected by the tide, causing swings and even axial stretching. At this time, the fixed end connected to the equipment is subject to a large load. If ordinary oil hoses are used for oil transportation operations, the connection end between the oil hose and the fixed equipment is easily damaged or even broken.

[0003] Therefore, in the prior art, the connection ends of ordinary oil transfer hoses and fixed equipment cannot meet the requirements of tensile strength and torsion resistance under high sea conditions, and are prone to damage or even pipe breakage, making it impossible to ensure the normal oil transfer process. Summary of the invention

[0004] The present invention provides a reinforced oil transfer hose and an oil transfer system to solve the technical problem in the prior art that the connection end of the ordinary oil transfer hose and the fixed equipment under high sea conditions cannot meet the requirements of tensile strength and torsion resistance, is very likely to be damaged or even the pipe body breaks, and the normal oil transfer process cannot be guaranteed.

[0005] According to a first aspect of the present invention, there is provided a reinforced oil hose, comprising: a pipe body and a reinforcement layer, wherein the reinforcement layer is coated on a portion of the pipe body, and the reinforcement layer extends from a portion of the pipe body between two ends to coat one of the ends of the pipe body; wherein, along the direction from the inside to the outside of the pipe body, the reinforcement layer comprises a steel wire wound armor layer, a third cord layer and an outer rubber layer arranged in sequence.

[0006] In this solution, a certain length of reinforcement layer is provided extending from the two ends of the pipe body to the ends of the pipe body, and the reinforcement layer is coated on the outer surface of the pipe body, and the reinforcement layer includes a steel wire wound armor layer, a third cord layer and an outer rubber layer. The beneficial effect of this solution is that in high sea conditions, the reinforcement layer coated with the oil hose can ensure the tensile and torsion resistance of the connection end of the oil hose and the fixed equipment, and the reinforcement layer will not be damaged or the pipe body will be broken, thereby ensuring the normal progress of the oil delivery process.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the pipe body is provided with an inner rubber layer, a first cord layer, a steel wire wound armor layer, a second cord layer and an outer rubber layer in sequence from the inside to the outside; and a middle rubber layer is provided between every two adjacent layers.

[0009] The beneficial effect of adopting the above further scheme is that the middle rubber layer arranged between two adjacent layers is made of natural rubber material with good fluidity, which can make the connection between adjacent layers more stable and not easy to delaminate. The inner rubber layer, the first cord layer, the steel wire wound armor layer, the second cord layer and the outer rubber layer arranged from the inside to the outside of the pipe body are respectively made of nitrile rubber material with strong corrosion resistance, aramid and steel wire mesh material with strong tensile resistance, and chloroprene and styrene-butadiene rubber mixed material with strong wear resistance, which can make the overall tolerance of the pipe body good, and have good corrosion resistance, wear resistance, tensile resistance and torsion resistance.

[0010] Furthermore, the inner rubber layer is a nitrile rubber layer; the first cord layer, the second cord layer and the third cord layer are all aramid layers; the steel wire wound armor layer is a steel wire mesh layer; the outer rubber layer is a mixed layer of chloroprene and styrene butadiene rubber; and the middle rubber layer is a natural rubber layer.

[0011] The beneficial effect of adopting the above further scheme is that the inner rubber layer is made of nitrile rubber material, which has strong corrosion resistance; the first cord layer, the second cord layer and the third cord layer are all made of aramid material, which has strong tensile resistance; the steel wire wound armor layer is made of wire mesh material, which has strong tensile and torsional resistance; the outer rubber layer is made of a mixture of chloroprene and styrene-butadiene rubber, which has strong wear resistance; the middle rubber layer is made of natural rubber material, which has strong fluidity and the connection between adjacent layers is more stable.

[0012] Furthermore, the first cord layer, the second cord layer and the third cord layer are all spirally wound on the middle rubber layer, and the spiral winding directions of the first cord layer and the second cord layer are opposite, and the spiral winding directions of the second cord layer and the third cord layer are opposite.

[0013] The beneficial effect of adopting the above further scheme is that the cord layer has the characteristics of high tensile strength and is not easy to break, and can be well integrated with other layers in combination with the middle rubber layer. The cord layer can be divided into a first cord layer, a second cord layer and a third cord layer, and the first cord layer, the second cord layer and the third cord layer are respectively combined with the middle rubber layer, and the cord layer is wound on the middle rubber layer in a spiral winding manner, wherein the spiral winding directions of the first cord layer and the second cord layer are opposite, and the spiral winding directions of the second cord layer and the third cord layer are opposite. The use of this winding method with opposite directions between adjacent cord layers can make the cord layer and the middle rubber layer more firmly connected, and have better tensile and torsion resistance.

[0014] Furthermore, it also includes: a connecting flange, the connecting flange is provided with a connecting pipe, the connecting pipe is sleeved in the tube wall of the tube body, an adhesive material layer is provided between the connecting pipe inside the tube body and the tube body, and the connecting pipe and the tube body are fixedly connected through the adhesive material layer; a clamping ring is provided on the outer surface of the connecting pipe, and the clamping ring is embedded in the tube wall of the tube body.

[0015] The beneficial effect of adopting the above further scheme is that the two ends of the enhanced hose provided by the present invention are provided with connecting flanges, the connecting flanges include flanges and connecting pipes, the connecting pipes are sleeved in the pipe body, and an adhesive material layer is provided between the connecting pipe and the pipe body, the adhesive material layer is composed of a special adhesive material (such as rubber and metal adhesive), the connecting pipe and the pipe body are bonded by the adhesive material, and the connection is more firmly. In addition, one or more clamping rings are also provided on the outer surface of the connecting pipe, and when the connecting pipe is connected to the pipe body, the clamping ring can be embedded in the inner wall of the pipe body, so that the connecting pipe and the pipe body can be connected more tightly and are not easy to be pulled off.

[0016] Furthermore, it also includes a fixing steel wire; the fixing steel wire is fixedly wound and arranged on the outer rubber layer of the reinforcement layer where the connection portion between the connecting pipe and the pipe body is located.

[0017] The beneficial effect of adopting the above further scheme is that the steel wire is fixedly wound around the connection between the connecting pipe and the pipe body, so that the connection between the connecting pipe and the pipe body is more firmly connected. Preferably, the steel wire is wound around the clamping ring, which can make the connection between the connecting pipe and the pipe body tighter and less likely to be pulled out.

[0018] Furthermore, the connecting flange comprises: a first connecting flange and a second connecting flange; the first connecting flange and the second connecting flange are respectively arranged at two ends of the pipe body; the first connecting flange is a fixed flange, and the second connecting flange is a loose flange.

[0019] The beneficial effect of adopting the above further scheme is that when the oil hose is connected to fixed equipment (including offshore oil tankers, single-point mooring equipment and beach equipment, etc.), since the pipe body floats on the sea surface, especially in high sea conditions, the pipe body is very susceptible to swinging due to the effect of tides. At this time, the fixed end connected to the equipment is subjected to a large load. The oil hose adopts a fixed flange at one end and a loose flange at the other end, which can effectively offset the load and ensure the normal oil transfer process.

[0020] Furthermore, the clamping ring is fixedly arranged on the outer wall of the connecting tube, the clamping ring is perpendicular to the axial direction of the connecting tube; and the clamping ring is embedded in the first cord layer.

[0021] The beneficial effect of adopting the above further solution is that the clamping ring arranged on the outer wall of the connecting tube is embedded in the first cord layer and is perpendicular to the axial direction of the connecting tube, so that the connection between the connecting tube and the tube body can be more firmly connected.

[0022] Furthermore, the length of the reinforcement layer in the axial direction of the tube body is greater than the length of the connecting tube sleeved into the tube wall of the tube body.

[0023] The beneficial effect of adopting the above further solution is that the length of the reinforcement layer is greater than the length of the connecting pipe sleeved in the pipe body, which can increase the tensile and torsional strength of the connection between the connecting pipe and the pipe body and is not prone to damage or breakage.

[0024] According to a second aspect of the present invention, an oil delivery system is provided, which includes an oil delivery device, an oil receiving device and the oil delivery hose as described above; the connecting flanges on the oil delivery hose are respectively connected to the oil delivery device and the oil receiving device.

[0025] In this solution, an enhanced oil transfer system is provided. During the oil transfer process, especially under high sea conditions, the connection between the oil transfer hose and the fixed equipment has high tensile and torsional strength, is not prone to damage or breakage, and can ensure the normal progress of the oil transfer process.

[0026] The present invention improves the tensile and torsional strength of the connection between the oil hose and the fixed equipment by arranging a reinforcement layer at the end of the pipe body, and then fixes the connecting flange to the pipe body of the oil hose through bonding and wire bundling technology, thereby solving the technical problem in the prior art that, under high sea conditions, the connection end between the ordinary oil hose and the fixed equipment cannot meet the requirements of tensile strength and torsional strength, is prone to damage and breakage, and cannot ensure the normal progress of the oil transfer process.

[0041] The present invention provides an enhanced oil delivery hose, please refer to Figure 1-Figure 5 The oil hose can be used in a point-to-point oil transportation system at sea under high sea conditions. The oil hose includes: a pipe body and a reinforcement layer 2. The reinforcement layer 2 is coated on a part of the pipe body, and the reinforcement layer 2 extends from the part of the pipe body between the two ends to one of the ends of the pipe body; wherein, along the direction from the inside to the outside of the pipe body, the reinforcement layer 2 includes a steel wire wound armor layer 6, a third cord layer 10 and an outer rubber layer 4 arranged in sequence.

[0042] Specifically, in this solution, a certain length of reinforcement layer 2 is provided extending from between the two ends of the pipe body to the ends of the pipe body, and the reinforcement layer 2 is coated on the outer surface of the pipe body, and the reinforcement layer 2 includes a steel wire wound armor layer 6, a third cord layer 10 and an outer rubber layer 4.

[0043] Compared with the prior art, the present invention can meet the requirements for tensile and torsion resistance of the connecting end of the oil delivery hose and the fixed equipment under high sea conditions, and is not prone to damage or breakage, thereby ensuring the normal progress of the oil delivery process.

[0044] In a further preferred embodiment, the tube body is provided with an inner rubber layer 8, a first cord layer 7, a steel wire wound armor layer 6, a second cord layer 3 and an outer rubber layer 4 in sequence from the inside to the outside; and a middle rubber layer 5 is provided between each two adjacent layers.

[0045] Specifically, in this solution, the middle rubber layer 5 arranged between two adjacent layers is made of natural rubber material with good fluidity, which can make the connection between adjacent layers more stable and not easy to delaminate. The inner rubber layer 8, the first cord layer 7, the steel wire wound armor layer 6, the second cord layer 3 and the outer rubber layer 4 arranged from the inside to the outside of the pipe body are respectively made of nitrile rubber material with strong corrosion resistance, aramid and steel wire mesh material with strong tensile resistance, and chloroprene and styrene-butadiene rubber mixed material with strong wear resistance, which can make the overall tolerance of the pipe body good, and have good corrosion resistance, wear resistance, tensile resistance and torsion resistance. Among them, the inner rubber layer 8 has high strength, low resistance, and good corrosion resistance to oil substances; the first cord layer 7, the steel wire wound armor layer 6 and the second cord layer 3 provide the oil hose with tensile resistance, torsion resistance and other characteristics; it should be noted that multiple cord layers can be set to enhance the overall tensile strength of the oil hose, and the multiple cord layers can be set between layers to ensure that the oil hose has a sufficiently large tensile strength. The outer rubber layer 4 has strong wear resistance and corrosion resistance; the middle rubber layer 5 has good fluidity and adhesion, and can be used as a connecting transition layer between layers.

[0046] Compared with the prior art, the scheme adopts an enhanced oil transfer hose provided by the present invention, which has the advantages of tensile resistance, torsion resistance, wear resistance, tolerance and good integration performance, and is more suitable for offshore oil transfer operations.

[0047] In a further preferred embodiment, the inner rubber layer 8 is a nitrile rubber layer; the first cord layer 7, the second cord layer 3 and the third cord layer 10 are all aramid layers; the steel wire wound armor layer 6 is a steel mesh layer; the outer rubber layer 4 is a mixed layer of chloroprene and styrene-butadiene rubber; and the middle rubber layer 5 is a natural rubber layer.

[0048] Specifically, in this solution, the inner rubber layer 8 is made of nitrile rubber material, so that the oil hose has strong corrosion resistance; the first cord layer 7, the second cord layer 3 and the third cord layer 10 are all made of aramid material, so that the oil hose has strong tensile resistance; the steel wire wound armor layer 6 is made of wire mesh material, so that the oil hose has strong tensile and torsion resistance; the outer rubber layer 4 is made of a mixture of chloroprene and styrene-butadiene rubber, so that the oil hose has strong wear resistance; the middle rubber layer 5 is made of natural rubber material, and due to its strong fluidity, the connection between adjacent layers will be more stable.

[0049] In a further preferred embodiment, the first ply 7, the second ply 3 and the third ply 10 are all spirally wound on the middle rubber layer 5, and the first ply 7 and the second ply 3 are spirally wound in opposite directions, and the second ply 3 and the third ply 10 are spirally wound in opposite directions.

[0050] Specifically, in the present embodiment, the cord layer has the characteristics of high tensile strength and is not easy to break. It can be well integrated with other layers in combination with the middle rubber layer 5. The cord layer can be divided into a first cord layer 7, a second cord layer 3 and a third cord layer 10. The first cord layer 7, the second cord layer 3 and the third cord layer 10 are respectively combined with the middle rubber layer 5, and the cord layer is wound on the middle rubber layer 5 in a spiral winding manner, wherein the first cord layer 7 and the second cord layer 3 are spirally wound in opposite directions, and the second cord layer 3 and the third cord layer 10 are spirally wound in opposite directions. The use of this winding method with opposite directions between adjacent cord layers can make the cord layer and the middle rubber layer 5 more firmly connected, and have better tensile and torsion resistance.

[0051] In a further preferred embodiment, it also includes: a connecting flange 1, the connecting flange 1 is provided with a connecting pipe, the connecting pipe is sleeved in the pipe wall of the pipe body, an adhesive material layer is provided between the connecting pipe inside the pipe body and the pipe body, and the connecting pipe and the pipe body are fixedly connected by the adhesive material layer; a clamping ring 9 is provided on the outer surface of the connecting pipe, and the clamping ring 9 is embedded in the pipe wall of the pipe body.

[0052] Specifically, in this solution, a reinforced hose provided by the present invention is provided with connecting flanges 1 at both ends. The connecting flanges 1 are used to connect the oil hose with a fixed device or another oil hose. The connecting flanges 1 include a flange and a connecting pipe. The diameter of the oil hose can be slightly smaller than the diameter of the connecting pipe. The body of the oil hose has a certain elasticity. After installation, the oil hose and the connecting pipe are more tightly connected. The connecting pipe is sleeved in the pipe body, and an adhesive material layer is provided between the connecting pipe and the pipe body. The adhesive material layer is composed of a special adhesive material. Preferably, the adhesive material can be selected from metal or rubber special glue, which has the characteristics of tensile resistance and torsion resistance. The connecting pipe and the pipe body are bonded by the adhesive material, and the connection is more firmly. In addition, one or more clamps 9 are also provided on the outer surface of the connecting pipe. When the connecting pipe is connected to the pipe body, the clamp 9 can be embedded in the inner wall of the pipe body, which can increase the resistance of the oil hose to being pulled off, so that the connecting pipe and the pipe body are more tightly connected. Optionally, a steel wire can be used to fix the connection pipe to the pipe body at the clamp ring 9; specifically, the steel wire is wrapped around the outer wall of the pipe body at the clamp ring 9 to tie and fix the pipe body and the connection pipe. The above connection methods are used simultaneously to meet the tensile and torsion resistance requirements of the oil hose under high sea conditions, and it is not easy to be pulled out, thereby ensuring the normal oil transportation process; it should be noted that multiple clamp rings 9 can be set on the connection pipe, and the clamp rings 9 can be welded to the outer surface of the connection pipe. The setting of multiple clamp rings 9 can make the connection between the pipe body and the connection pipe more stable, and have stronger tensile and torsion resistance.

[0053] In a further preferred embodiment, it also includes a fixing steel wire; the fixing steel wire is fixedly wound and arranged on the outer rubber layer 4 of the reinforcement layer 2 where the connection portion between the connecting pipe and the pipe body is located.

[0054] Specifically, in this solution, a steel wire is used to be fixedly wound around the connection between the connecting pipe and the pipe body, so that the connection between the connecting pipe and the pipe body is more firmly established. Preferably, the steel wire is wound around the clamping ring 9, so that the connection between the connecting pipe and the pipe body is more tightly connected and is not easily pulled out.

[0055] In a further preferred embodiment, the connecting flange 1 comprises: a first connecting flange 1 and a second connecting flange 1; the first connecting flange 1 and the second connecting flange 1 are respectively arranged at two ends of the pipe body; the first connecting flange 1 is a fixed flange, and the second connecting flange 1 is a loose flange.

[0056] Specifically, in this solution, when the oil hose is connected to fixed equipment (including offshore oil tankers, single-point mooring equipment, and shore equipment, etc.), since the pipe body floats on the sea surface, especially in high sea conditions, the pipe body is very susceptible to the effect of the tide and swings. At this time, the fixed end connected to the equipment is subjected to a large load. The oil hose uses a fixed flange at one end and a loose flange at the other end, which can effectively offset the load and ensure the normal progress of the oil transportation process. It should be noted that the fixed flange can be connected to the oil transportation end equipment, and the loose flange can be connected to the oil receiving end equipment. When the oil hose swings and twists irregularly under the action of external force, the loose flange, with its unique structural characteristics, follows the swing and twist of the oil hose, and can effectively offset the torque generated by the twisting of the oil hose in the axial direction. During the oil transportation process, the oil hose will not be knotted due to the twisting of the oil hose, affecting the normal progress of the oil transportation process.

[0057] Optionally, loose-fitting flanges can be used at both ends of the oil delivery hose at the same time. The loose-fitting flanges are respectively connected to the oil delivery end equipment and the oil receiving end equipment. When the oil delivery hose is subjected to external force, irregular swing and twisting occur. The loose-fitting flange can follow the swing and twisting of the oil delivery hose to offset the torque generated by the twisting of the oil delivery hose in the axial direction. During the oil delivery process, the oil delivery hose will not become tangled due to the twisting, thereby affecting the normal progress of the oil delivery process.

[0058] In a further preferred embodiment, the collar 9 is fixedly disposed on the outer wall of the connecting tube in a surrounding manner, and the collar 9 is perpendicular to the axial direction of the connecting tube; and the collar 9 is embedded in the first cord layer 7 .

[0059] Specifically, in this solution, the clamp ring 9 can be welded and fixed on the outer wall of the connecting pipe, and the clamp ring 9 is perpendicular to the axial direction of the connecting pipe. When the connecting pipe is connected to the pipe body, the clamp ring 9 is arranged perpendicular to the connecting pipe to increase the resistance of the oil hose body to being pulled out. The clamp ring 9 arranged on the outer wall of the connecting pipe is embedded in the first cord layer 7, which can make the connection between the connecting pipe and the pipe body more firmly. If the pipe body and the connecting pipe are fixed with steel wire, the steel wire can also be used to more firmly bind the pipe body and the connecting pipe. When the above three connection methods are used at the same time, the oil hose rarely pulls out.

[0060] In a further preferred embodiment, the length of the reinforcement layer 2 in the axial direction of the pipe body is greater than the length of the connecting pipe sleeved into the pipe wall of the pipe body.

[0061] Specifically, in the present embodiment, the length of the reinforcing layer 2 is greater than the length of the connecting pipe sleeved in the pipe body, which can increase the tensile and torsional strength of the connection between the connecting pipe and the pipe body, and can better protect the metal connecting pipe sleeved in the oil hose body and the oil hose body, and is not prone to damage or breakage.

[0062] Compared with the prior art, this solution improves the tensile and torsional strength of the connection between the oil hose and the fixed equipment by providing a reinforcement layer 2 at the end of the pipe body, ensuring the connection quality of the connection between the oil hose and the fixed equipment under high sea conditions, and is not prone to damage or breakage. The connecting flange 1 is fixedly connected to the pipe body of the oil hose by bonding and wire bundling technology, which enhances the tensile strength of the oil hose in the radial direction and makes it less likely to be pulled out.

[0063] According to a second aspect of the present invention, there is provided an oil delivery system. Figure 6 The system includes an oil delivery device 11, an oil receiving device 13 and the oil delivery hose 12 as described above; the connecting flange 1 on the oil delivery hose 12 is connected to the oil delivery device 11 and the oil receiving device 13 respectively.

[0064] Specifically, in this solution, an enhanced oil transfer system is provided. During the oil transfer process, especially under high sea conditions, the connection between the oil transfer hose 12 and the fixed equipment has high tensile and torsional strength, is not prone to damage or breakage, and can ensure the normal progress of the oil transfer process.

[0065] The present invention improves the tensile and torsional strength of the connection between the oil hose 12 and the fixed equipment by arranging a reinforcement layer 2 at the end of the pipe body, and then fixes the connecting flange 1 to the pipe body of the oil hose 12 through bonding and wire bundling technology, thereby solving the technical problem in the prior art that, under high sea conditions, the ordinary oil hose 12 cannot meet the requirements of tensile strength and torsional strength, is prone to damage and breakage, and cannot ensure the normal progress of the oil transfer process.

[0066] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
