Description

Technical Field

[0001] The invention relates to the technical field of offshore floating production storage and offloading vessels, and in particular to a riser pipe clamp and a method for manufacturing the pipe clamp. Background Art

[0002] Floating production storage and offloading vessels (FPSO) are offshore floating production storage and offloading devices that integrate production, storage and unloading of oil, and are key equipment for the development of offshore oil. When FPSO is conducting oil production at sea, the shaking of the waves causes relative movement between the FPSO's hull and the oil production riser, affecting the connection and fixation of the riser. Therefore, a flexible rubber coating needs to be provided between the riser and the pipe clamp, that is, on the inner surface of the pipe clamp, to cushion the impact between the riser and the pipe clamp. During the production process of the rubber coating of the riser pipe clamp, it is necessary to vulcanize the flat rubber on the inner surface of the steel pipe clamp, and form semicircular raised ribs on the other surface of the flat rubber.

[0003] In the existing processing and manufacturing mode of rubber coating for vertical pipe clamps, a cylindrical molding mold is first made and assembled with the upper and lower pipe clamps, and then a certain amount of raw rubber is filled into the cavity between the mold and the pipe clamp, and the pipe clamp is tightened by screws to squeeze the rubber for shaping. At the same time, in this process, the mold needs to be vulcanized as a whole so that the rubber can fit on the inner surface of the pipe clamp. And after the vulcanization is completed, the rubber is cut from the upper and lower pipe clamps and the upper and lower pipe clamps are disassembled.

[0004] However, in the existing processing and manufacturing mode of the riser pipe clamp rubber coating, the processing cycle is long, and manual extrusion is required, the production labor intensity is high, resulting in low production efficiency. Summary of the invention

[0005] The object of the present invention is to provide a riser pipe clamp, which can fix the rubber lagging on the pipe clamp through vulcanization and simplify the fluidization process.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] According to one aspect of the present invention, there is provided a riser pipe clamp for clamping on the outer peripheral side of a riser, the riser pipe clamp comprising: a pipe clamp assembly, which is provided with two pipe clamps that can be connected to each other; a clamping groove is provided on the inner side of the pipe clamp, and the inner peripheral wall of the clamping groove is arc-shaped; the two pipe clamps are connected in a manner that the clamping grooves are opposite to each other, so that the two clamping grooves can embrace the outer peripheral side of the riser; two rubber-coated parts are arranged one by one corresponding to the two pipe clamps; the rubber-coated parts are flexible; the rubber-coated parts include a main body and a plurality of protrusions formed on the main body; one side of the main body is attached to and fixed on the inner peripheral wall of the clamping groove; the protrusion is located on the side of the main body away from the inner peripheral wall of the clamping groove, the length of the protrusion extends along the axial direction of the pipe clamp, and the plurality of protrusions are arranged at intervals along the circumference of the clamping groove; wherein the main body and the inner peripheral wall of the clamping groove are fixedly connected by a vulcanization process.

[0008] In one embodiment of the present application, the raised portion is obtained by compression molding of the rubber-coated component.

[0009] In one embodiment of the present application, the radial cross-section of the protrusion is arc-shaped.

[0010] In one embodiment of the present application, tops of the plurality of protrusions are located in the same plane.

[0011] In one embodiment of the present application, the rubber-coated component is a rubber component.

[0012] In one embodiment of the present application, a hinged portion is provided on the pipe clamp; the two pipe clamps are hinged via the hinged portion so that the two pipe clamps can rotate relative to each other and clamp onto or release from the outer circumference of the riser.

[0013] The present application also provides a pipe clamp manufacturing method, which is applicable to any of the above mentioned riser pipe clamps. The pipe clamp manufacturing method comprises the following steps:

[0014] Providing and forming the rubber-encapsulated component so that the main body is formed with a plurality of the protrusions arranged at intervals;

[0015] The rubber-coated parts are placed in the clamping grooves of the two pipe clamps respectively, so that the side of the main body away from the protruding part is closely attached to the inner peripheral wall of the clamping groove, and fixed;

[0016] The rubber-coated part and the clamping groove are steam-pressurized so that the main body is vulcanized and fixed in the clamping groove.

[0017] In one embodiment of the present application, the pipe clamp manufacturing method further includes the following step: after the rubber-coated part is pressed, the surface of the raised portion is vulcanized.

[0018] In one embodiment of the present application, the pipe clamp manufacturing method further includes the following step: applying an adhesive in the clamping groove to bond the main body in the clamping groove.

[0019] In one embodiment of the present application, the pipe clamp manufacturing method further includes the following steps: after placing the rubber-coated component in the clamping groove, a clamp is used to clamp the rubber-coated component in the clamping groove to limit the position of the rubber-coated component.

[0020] It can be seen from the above technical solution that the present invention has at least the following advantages and positive effects:

[0021] In the present invention, the riser pipe clamp includes two pipe clamps and two rubber-coated parts. A clamping groove is provided inside the pipe clamp, and the clamping groove is arc-shaped, so that the two pipe clamps can be wrapped around the outer peripheral side of the riser. The rubber-coated part is provided with a main body and a plurality of protrusions, and one side of the main body can be fitted on the inner peripheral wall of the clamping groove, and the protrusion is located on the side of the main body away from the clamping groove, so that the protrusion can be pressed against the outer peripheral side of the riser to support the riser and buffer the impact force between the riser and the pipe clamp assembly.

[0022] At the same time, the main body of the rubber-coated part is directly fixed on the inner wall of the clamping groove through a vulcanization process, thereby simplifying the connection process between the rubber-coated part and the pipe clamp and shortening the vulcanization time of the rubber-coated part, thereby improving the production efficiency of the pipe clamp.

[0033] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0034] In the description of the present invention, it is to be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] In the existing processing and manufacturing mode of rubber coating for vertical pipe clamps, a cylindrical molding mold is first made and assembled with the upper and lower pipe clamps, and then a certain amount of raw rubber is filled into the cavity between the mold and the pipe clamp, and the pipe clamp is tightened by screws to squeeze the rubber for shaping. At the same time, in this process, the mold needs to be vulcanized as a whole so that the rubber can fit on the inner surface of the pipe clamp. And after the vulcanization is completed, the rubber is cut from the upper and lower pipe clamps and the upper and lower pipe clamps are disassembled.

[0037] Based on the above reasons, the existing processing and manufacturing process of the rubber coating of the riser pipe clamp has the following shortcomings: 1. The pipe clamp needs to be vulcanized with a mold, and the vulcanization time is long, which leads to a long overall processing cycle of the pipe clamp. 2. Due to the low efficiency of mold reuse, in order to meet the production capacity requirements, multiple sets of molds need to be invested to ensure that the production capacity can meet the output requirements, resulting in high investment costs. 3. The circular pipe clamp is not easy to achieve mechanical pressurization operation, and requires manual extrusion, resulting in high labor intensity and low production efficiency. It is also not easy to form mass production, resulting in high processing costs for the pipe clamp. 4. The fluidity of rubber is poor after heating, resulting in poor molding ability of the semicircular protrusions, which is easy to cause quality defects such as pores and cracks.

[0038] Based on the above reasons, a riser pipe clamp is now proposed to solve the above problems.

[0039] The scheme is further illustrated by the following examples:

[0040] Figure 1 Schematic diagram of a riser pipe clamp according to an embodiment of the present invention. Figure 2 yes Figure 1 Schematic diagram of the riser pipe clamp and riser. Figure 3 yes Figure 1 Schematic diagram of a front view of a riser pipe clamp.

[0041] See also Figure 1 , Figure 2 and Figure 3 The riser pipe clamp of this embodiment is applied to an offshore floating production storage and offloading vessel, and the riser pipe clamp is used to clamp on the outer peripheral side of the riser 1 to support the riser 1 .

[0042] Specifically, the riser pipe clamp may include two pipe clamps 11 , two rubber-coated parts 20 and a support frame 14 .

[0043] One end of the support frame 14 is connected to the floating production storage and offloading vessel, and the other end of the support frame 14 is connected to one of the pipe clamps 11, so that the pipe clamp 11 can be supported on the hull through the support frame.

[0044] A clamping groove 12 may be provided on the inner side of the pipe clamp 11. The inner peripheral wall of the clamping groove 12 is arc-shaped, that is, the clamping groove 12 may be provided as an arc-shaped groove, so that the clamping groove 12 can adapt to the outer peripheral side of the stand pipe 1. At the same time, the two pipe clamps 11 are connected in a manner that the clamping grooves 12 are opposite to each other, so that the two clamping grooves 12 can surround the outer peripheral side of the stand pipe 1.

[0045] In this embodiment, the two pipe clamps 11 and the support frame 14 are both made of metal material.

[0046] See also Figure 1 and Figure 2A hinge portion 13 is provided on the pipe clamp 11, and the two pipe clamps 11 are hinged by the hinge portion 13, so that the two pipe clamps 11 can rotate relative to each other and clamp on or release from the outer peripheral side of the riser 1, thereby facilitating the clamping of the riser 1 by the riser pipe clamp.

[0047] In addition, the two pipe clamps 11 may be provided with a fastening portion 15. The fastening portion 15 is provided with a through hole for installing a connector so that the connector can connect the two pipe clamps 11 together. The fastening portion 15 and the hinge portion 13 are respectively located on both sides of the clamping groove 12 in the radial direction, so that after the two pipe clamps 11 rotate around the hinge portion 13, the two pipe clamps 11 are fixedly connected together through the fastening portion 15 and are surrounded on the outer peripheral side of the riser 1.

[0048] It should be noted that the connecting piece can be set as a connecting bolt. Of course, the connecting piece can also be set as a locking structure to fasten the two pipe clamps 11 together.

[0049] See also Figure 1 and Figure 3 The two rubber-coated parts 20 are respectively arranged in the clamping grooves 12 of the two pipe clamps 11, so that when the two pipe clamps 11 are wrapped around the outer circumference of the vertical pipe 1, the rubber-coated parts 20 can be pressed between the pipe clamps 11 and the vertical pipe 1.

[0050] In this embodiment, the rubber coating 20 may be flexible so that the rubber coating 20 can buffer the impact force between the riser 1 and the pipe clamp 11, ensure the safe connection between the pipe clamp 11 and the riser 1, and avoid the connection between the pipe clamp 11 and the riser 1 being affected by the shaking of the hull.

[0051] Figure 4 yes Figure 1 Schematic diagram of the pipe clamp and rubber-coated parts of the riser pipe clamp. Figure 5 yes Figure 1 Schematic diagram of a top view of a rubber-encapsulated part. Figure 6 yes Figure 1 Schematic diagram of a side view of a rubberized part. Figure 7 yes Figure 1 Schematic diagram of placing the rubber-coated part in the clamping groove.

[0052] See also Figure 4-7 The rubber package 20 may include a main body 21 and a plurality of protrusions 22 .

[0053] The main body 21 may be in the shape of a flat plate, one side of the main body 21 may be attached to the inner peripheral wall of the clamping groove 12, and the main body 21 may be fixed to the inner peripheral wall of the clamping groove 12 after vulcanization.

[0054] The protrusion 22 is formed on the main body 21, and the protrusion 22 is located on the side of the main body 21 away from the inner peripheral wall of the clamping groove 12. The length of the protrusion 22 extends along the axial direction of the pipe clamp 11, and a plurality of protrusions 22 are arranged at intervals along the circumference of the pipe clamp 11, that is, after the rubber-coated part 20 is attached and fixed in the clamping groove 12, the plurality of protrusions 22 can be arranged at intervals along the circumference of the clamping groove 12.

[0055] It should be noted that, since the rubber-coated part 20 is flexible, after the rubber-coated part 20 is attached to the inner wall of the clamping groove 12, the main body 21 and the protrusions 22 can deform along the shape of the clamping groove 12, so that the shape of the main body 21 also becomes an arc, and the multiple protrusions 22 located on the main body 21 are also arranged at intervals along the circumference of the clamping groove 12 due to the deformation of the main body 21.

[0056] In this embodiment, the rubber-coated member 20 can be set as a rubber member. The rubber member is flexible so that the rubber-coated member 20 can buffer the impact of the riser 1 on the pipe clamp assembly 10, thereby ensuring the safety of the connection between the pipe clamp assembly 10 and the riser 1.

[0057] It should be noted that the rubber-coated component 20 may also be made of a flexible plastic material, so that the rubber-coated component 20 can buffer the impact of the riser 1 on the pipe clamp assembly 10 .

[0058] See also Figure 6 and Figure 7 The main body 21 and the raised portion 22 can be integrally formed, that is, before the rubber-coated part 20 is attached to the clamping groove 12, the rubber-coated part 20 has already formed the main body 21 and the raised portion 22 structure, and the main body 21 and the raised portion 22 are set as a whole, thereby reducing the process of installing the rubber-coated structure to the clamping groove 12 and then forming the raised portion 22 by pressing, thereby simplifying the installation of the pipe clamp assembly 10 and the rubber-coated part 20, and reducing the labor intensity of the operating workers. In addition, the above method can also avoid quality defects caused by poor fluidity of rubber after heating.

[0059] Specifically, the rubber-coated member 20 can be pressed to obtain the raised portion 22 , that is, the rubber-coated member 20 is pressed from a flat member to form the main body 21 and the raised portion 22 in one piece.

[0060] Of course, in some other embodiments, the rubber-coated component 20 may also be configured to be formed by connecting a separate main body portion 21 and a protruding portion 22 to obtain an integrated rubber-coated component 20 .

[0061] See also Figure 3 and Figure 4, the radial cross section of the protrusion 22 can be set to be an arc, that is, in the radial direction of the clamping groove 12, the cross section of the protrusion 22 is an arc, so that the protrusion 22 can be against the outer peripheral side of the riser 1. At the same time, it should be noted that after the rubber-coated part 20 is attached to the clamping groove 12, a plurality of protrusions 22 can be arranged at intervals around the central axis of the clamping groove 12, so that after the protrusion 22 is squeezed and collided by the riser 1, the protrusion 22 is provided with space for deformation due to the interval between two adjacent protrusions 22, so that the protrusion 22 and the main body 21 can play a buffering role.

[0062] Furthermore, in some other embodiments, the cross section of the protrusion 22 may also be set to be rectangular or triangular, etc., so that the protrusion 22 can abut against the outer peripheral side of the stand pipe 1.

[0063] See also Figure 6 In this embodiment, the tops of the plurality of protrusions 22 are located in the same plane, so that after the rubber-coated component 20 is attached to the inner circumferential wall of the clamping groove 12, the plurality of protrusions 22 can simultaneously abut against the outer circumferential side of the riser 1, thereby ensuring that the rubber-coated component 20 and the pipe clamp assembly 10 can embrace the circumferential side of the riser 1.

[0064] See also Figure 3 and Figure 4 The main body 21 is fixedly connected to the inner circumferential wall of the clamping groove 12 through a vulcanization process. Specifically, after the rubber-coated part 20 is attached to the inner circumferential wall of the clamping groove 12, the main body 21 is vulcanized on the side facing the clamping groove 12 by steam pressurization, and is fastened to the inner circumferential wall of the clamping groove 12, thereby preventing the rubber-coated part 20 from falling off from the clamping groove 12.

[0065] Figure 8 It is a flow chart of the pipe clamp manufacturing method of the present application.

[0066] See also Figure 8 The present application also discloses a pipe clamp manufacturing method, which is applicable to the aforementioned riser pipe clamp.

[0067] Specifically, the pipe clamp manufacturing method includes the following steps:

[0068] Step 1: Provide and form a rubber-coated member 20, so that a main body 21 is formed with a plurality of spaced protrusions 22. That is, before the rubber-coated member 20 is attached to the inner peripheral wall of the clamping groove 12, the rubber-coated member 20 has already formed a main body 21 and a plurality of protrusions 22, so as to facilitate the attachment of the rubber-coated member 20 to the inner peripheral wall of the clamping groove 12.

[0069] Step 2: Place the rubber-coated parts 20 in the clamping grooves 12 of the two pipe clamps 11 accordingly, so that the side of the main body 21 away from the protrusion 22 is tightly attached to the inner peripheral wall of the clamping groove 12, and fix it.

[0070] Step 3: Steam pressurize the rubber-coated part 20 and the clamping groove 12 so that the main body 21 is vulcanized and fixed in the clamping groove 12. Specifically, when the rubber-coated part 20 is steam-pressurized, the side of the main body 21 away from the protrusion 22 can be vulcanized and fixed on the inner peripheral wall of the clamping groove 12, thereby fixing the rubber-coated part 20 on the inner peripheral wall of the clamping groove 12.

[0071] It should be noted that, in this embodiment, the pipe clamp manufacturing method further includes the following steps: after the rubber-coated part 20 is pressed, the surface of the protruding part 22 is first vulcanized. That is, between step 1 and step 2, after the rubber-coated part 20 is pressed, the protruding part 22 and the side of the main body 21 facing the protruding part 22 are first vulcanized, thereby reducing the vulcanization process after the rubber-coated part 20 is attached to the inner circumferential wall of the clamping groove 12, thereby reducing the vulcanization time after the rubber-coated part 20 is installed on the pipe clamp 11, thereby improving the overall vulcanization efficiency.

[0072] Therefore, compared with the prior art, in the pipe clamp manufacturing method of the present application, after the rubber-coated part 20 is installed on the pipe clamp 11, only the side of the main body 21 facing away from the raised part 22 needs to be vulcanized, and there is no need to vulcanize the raised part 22 and the side of the main body 21 facing the raised part 22, thereby reducing the vulcanization time of the rubber-coated part 20 with the pipe clamp, thereby improving the overall vulcanization efficiency.

[0073] At the same time, the pipe clamp manufacturing method also includes the following steps: applying an adhesive in the clamping groove 12 to bond the main body 21 in the clamping groove 12. That is, in step 2, before the main body 21 is attached to the inner peripheral wall of the clamping groove 12, the adhesive is first applied on the inner peripheral wall of the clamping groove 12, so that the main body 21 can be attached and fixed on the inner peripheral wall of the clamping groove 12, and the rubber-coated part 20 is prevented from falling off from the clamping groove 12. That is, the adhesive can play a role in fixing and bonding the rubber-coated part 20 to the inner peripheral wall of the clamping groove 12.

[0074] It should be noted that the adhesive is only used to temporarily fix the rubber-coated part 20 in the clamping groove 12, and the adhesive can be decomposed after steam pressure vulcanization, so as to avoid the adhesive affecting the connection stability between the rubber-coated part 20 and the pipe clamp 11.

[0075] In addition, the pipe clamp manufacturing method further includes the following steps: after placing the rubber-coated part 20 in the clamping groove 12, the rubber-coated part 20 is clamped in the clamping groove 12 by a clamp to limit the position of the rubber-coated part 20. That is, between step 2 and step 3, the rubber-coated part 20 is fixed in the clamping groove 12 by a clamp to prevent the rubber-coated part 20 from relative displacement with the pipe clamp 11 during the vulcanization process, to ensure that the position between the rubber-coated part 20 and the pipe clamp 11 meets the requirements, and to improve the yield after vulcanization.

[0076] In summary, in the pipe clamp manufacturing method, the rubber-coated part 20 is first pressed into a body 21 and a protruding part 22, and the protruding part 22 is vulcanized. At the same time, the rubber-coated part 20 with the protruding part 22 and the body 21 is attached to the clamping groove 12, and the side of the body 21 attached to the inner circumferential wall of the clamping groove 12 is vulcanized, so that the body 21 can be fixed on the inner circumferential wall of the clamping groove 12, that is, the vulcanization time of the rubber-coated part 20 on the pipe clamp 11 can be reduced, and the rubber-coated part 20 can be fixed on the pipe clamp 11, thereby simplifying the installation and vulcanization fixation of the rubber-coated part, improving the production efficiency of the riser pipe clamp, and reducing the production cost.

[0077] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
