Description

Technical Field

[0001] The utility model relates to the technical field of steel-plastic composite pipes, in particular to PEPOW steel-plastic composite pipes. Background Art

[0002] Steel-plastic composite pipes are emerging composite pipe materials, which are simply called steel-plastic pipes in many places. They can be classified according to the structure of the pipes into: steel belt reinforced steel-plastic composite pipes, seamless steel pipe reinforced steel-plastic composite pipes, perforated steel belt steel-plastic composite pipes, and steel wire mesh skeleton steel-plastic composite pipes. The plastic of steel-plastic composite pipes is generally polyethylene, that is, PE.

[0003] However, when the existing polyethylene steel-plastic composite pipes are connected, due to the large pressure at the connection, the mechanical properties of pure polyethylene are average, which easily makes the connection unstable during high-pressure transportation work. At the same time, in a relatively harsh environment, such as the low temperature at night in the desert and gobi, the existing pipes cannot effectively ensure that the fluid can be smoothly transported.

[0004] Therefore, this solution proposes PEPOW steel-plastic composite pipes to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art, and propose PEPOW steel-plastic composite pipes.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The PEPOW steel-plastic composite pipe includes a steel pipe. An inner layer pipe is arranged on the inner wall of the steel pipe, and an outer layer pipe is arranged on the outer wall of the steel pipe. Both ends of the outer layer pipe are fixedly connected with outer layer rings. On one side wall of each of the two outer layer rings close to the steel pipe, an auxiliary pipe is fixedly connected. Both of the two auxiliary pipes are arranged on the inner wall of the inner layer pipe. The outer layer pipe, the outer layer rings and the auxiliary pipes are all made of periodate-oxidized wood, the inner layer pipe is made of polyethylene material, and connection structures are arranged at both ends of the steel pipe.

[0008] Preferably, the connection structure includes a plurality of connectors arranged on the outer wall of the steel pipe. The plurality of connectors are arranged in central symmetry. One end of each of the plurality of connectors away from the steel pipe penetrates through the outer layer pipe, and one ends of the plurality of connectors away from the steel pipe are jointly fixedly connected with a connection disk. A plurality of connection holes arranged in central symmetry are arranged on the connection disk.

[0009] Preferably, arc-shaped grooves are arranged on one side wall of each of the two outer layer rings away from the outer layer pipe, and arc-shaped pieces are fixedly connected to one side wall of each of the two outer layer rings away from the outer layer pipe. Both of the two arc-shaped pieces are made of periodate-oxidized wood.

[0010] Preferably, it further includes a plurality of connecting components. The connecting component includes a connecting column, which is matched with the connecting hole. Both ends of the connecting column are fixedly connected with threaded blocks, and both of the threaded blocks are fixedly connected with connecting nuts.

[0011] Preferably, auxiliary rings are fixedly connected to the side walls of both of the connecting nuts close to the connecting column.

[0012] Preferably, a plurality of the connecting members are all made of polytetrafluoroethylene material.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, by virtue of the characteristics of the outer layer pipe made of wood oxidized by periodic acid, it can absorb solar energy during the day and slowly release heat on cloudy days or at night to maintain a relatively constant pipe temperature, enabling the fluid in the pipe to stably complete the conveying work in a complex environment. At the same time, for the outer layer ring made of wood oxidized by periodic acid, due to the porous structure and mechanical properties of the wood oxidized by periodic acid, the obtained porous support can withstand a high pressure 500 times its own weight without liquid leakage, having an excellent encapsulation effect, effectively ensuring the stability of the connection, and then enabling the fluid conveying work to be completed safely and stably.
