Description

Technical Field

[0001] This application relates to the field of RTP pipes, and in particular to the structure of RTP pipe materials. Background Art

[0002] An RTP pipe is a new type of flexible medium and high pressure environmental protection composite material pipe formed by combining high molecular materials such as PE, PVC, PP, and PB with a variety of high-strength fibers. Its density is only one-sixth of that of steel, and its tensile strength can reach several times that of steel. It has the characteristics of being non-toxic, odorless, corrosion-resistant, high-pressure resistant, light in weight, good in toughness, and not easy to scale, and can be widely used in industries such as water conservancy, municipal administration, petroleum, gas, coal, and chemical industry for the transportation of water, oil, gas, brine, hydrogen, emulsion, methanol injection, and other corrosive fluids.

[0003] Existing RTP pipes usually have low compressive performance and are only suitable for transporting highly corrosive media, and cannot be applied to some scenarios with high internal pressure or external pressure, which is not convenient for use. Utility Model Content

[0004] This application provides a structure of RTP pipe material to solve the problems raised in the above background art.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] The structure of RTP pipe material includes an inner pipe, a fiber layer is sleeved outside the inner pipe, a structure strengthening layer is sleeved outside the fiber layer, an outer pipe is sleeved outside the structure strengthening layer, the structure strengthening layer includes a number of fixing rings, the fixing rings are sleeved outside the fiber layer, a number of fixing slots are opened inside the fixing rings, reinforcing ribs are snap-fitted inside the fixing slots, and a filling glue is wrapped outside the fixing rings and the reinforcing ribs, and the filling glue is arranged between the fiber layer and the outer pipe.

[0007] By adopting the above scheme, through the setting of the fiber layer, it is convenient to improve the mechanical function of the device, make the device have high tensile performance, and can increase the impact resistance of the device, and can effectively absorb and disperse external forces. Through the setting of the structure strengthening layer, it is convenient to improve the compressive performance of the device, make the device maintain good structural stability when subjected to external pressure, and make the device applicable to more different scenarios. By opening a number of fixing slots inside the fixing rings and snap-fitting the reinforcing ribs inside the fixing slots, it is convenient to fixedly install the reinforcing ribs outside the fiber layer, so that the reinforcing ribs can improve the compressive performance of the device. By arranging the filling glue between the fiber layer and the outer pipe, it is convenient to improve the installation stability of the reinforcing ribs, so that the reinforcing ribs can effectively improve the compressive performance of the device.

[0008] Furthermore, the material of the reinforcing rib is glass fiber material, and the reinforcing rib is axially parallel to the inner pipe.

[0009] By adopting the above solution, the reinforcing rib is made of fiberglass material, and the reinforcing rib is axially parallel to the inner tube. The strength and elastic modulus of glass fiber are very high, enabling the device to withstand higher internal pressure and external load and not easily deform.

[0010] Furthermore, the filling glue is made of foamed resin.

[0011] By adopting the above solution, since the filling glue is made of foamed resin, it is convenient for the filling glue to fill the space between the fiber layer and the outer tube, which can improve the installation stability of the reinforcing rib and can play a certain buffering and heat insulation effect.

[0012] Furthermore, the inner tube and the outer tube are both made of ultra-high molecular weight polyethylene material.

[0013] By adopting the above solution, since the inner tube and the outer tube are both made of ultra-high molecular weight polyethylene material, the ultra-high molecular weight polyethylene material has relatively high hardness, which can effectively improve the wear resistance of the inner side of the inner tube and the outer side of the outer tube, thereby increasing the service life of the device.

[0014] Furthermore, the inner tube includes a tube body, and a plurality of flow guiding strips are arranged inside the tube body.

[0015] By adopting the above solution, through the arrangement of the flow guiding strips, it is convenient to guide the fluid to flow in a predetermined direction and mode, avoiding directly impacting the inner wall of the inner tube or generating eddy currents, thereby reducing energy loss and improving the conveying efficiency.

[0016] Furthermore, the flow guiding strips are axially parallel to the tube body, and the edges of the flow guiding strips are in an arc-shaped structure.

[0017] By adopting the above solution, since the edges of the flow guiding strips are in an arc-shaped structure, it is convenient to reduce wear and effectively increase the service life.

[0018] Furthermore, the fiber layer includes fiber strips, and the fiber strips are wound around the outer side of the inner tube in a spiral structure.

[0019] By adopting the above solution, since the fiber strips are wound around the outer side of the inner tube in a spiral structure, it is convenient to evenly distribute stress and can effectively improve the structural strength.

[0020] Furthermore, the fiber strips are carbon fiber tapes impregnated with epoxy resin, and the width of the fiber strips is four times the height of the spiral structure of the fiber strips.

[0021] By adopting the above scheme, the fiber strip is a carbon fiber tape impregnated with epoxy resin, and the width of the fiber strip is four times the height of the spiral structure loop of the fiber strip. Carbon fiber has extremely high strength and low density characteristics. After being pre-impregnated with epoxy resin, it can better combine with the inner tube during the winding process to form a tight and uniform composite structure, and can wind four layers of fiber strips on the outer side of the inner tube, effectively improving the performance of the device.

[0022] In summary, the present application has the following technical effects:

[0023] By setting the fiber layer, it is convenient to improve the mechanical function of the device, making the device have high tensile performance, and can increase the impact resistance of the device, effectively absorbing and dispersing external forces. By setting the structural strengthening layer, it is convenient to improve the compressive performance of the device, enabling the device to maintain good structural stability when subjected to external pressure, so that the device can be applied to more different scenarios. By providing a number of fixing slots on the inner side of the fixing ring, and a reinforcing rib is snap-fitted inside the fixing slot, it is convenient to fixedly install the reinforcing rib on the outer side of the fiber layer, so that the reinforcing rib can improve the compressive performance of the device. By setting the filling glue between the fiber layer and the outer tube, it is convenient to improve the stability of the installation of the reinforcing rib, so that the reinforcing rib can effectively improve the compressive performance of the device.

The fixing rings 10301 and the reinforcing rib 10302 are wrapped with a filling glue 10304. The filling glue 10304 is arranged between the fiber layer 102 and the outer pipe 104. Through the arrangement of the filling glue 10304 between the fiber layer 102 and the outer pipe 104, it is convenient to improve the installation stability of the reinforcing rib 10302, so that the reinforcing rib 10302 can effectively improve the compressive performance of the device. The material of the reinforcing rib 10302 is a glass fiber material, and the reinforcing rib 10302 is axially parallel to the inner pipe 101. Through the material of the reinforcing rib 10302 being a glass fiber material and the reinforcing rib 10302 being axially parallel to the inner pipe 101, both the strength and elastic modulus of the glass fiber are very high, enabling the device to withstand higher internal pressure and external loads and not easily deform.
