Embodiment Construction

[0010] Such as figure 1 It is a structural schematic diagram of the present invention, a synthetic steel pipe, including a pipe body 1, and the pipe body 1 is composed of a stainless steel layer 2 and a PE resin layer 3. The stainless steel layer 2 is located on the outer layer of the pipe body 1, and the PE resin layer 3 is located on the inner layer of the pipe body 1.

[0011] The pipe body 1 is designed as a composite structure of two materials. The stainless steel layer 2 is located on the outer layer of the pipe body 1, and the PE resin layer 2 is located on the inner layer of the pipe body 1. The two materials complement each other, which not only retains the excellent characteristics of the stainless steel layer 2, but also The advantages of the PE resin layer 3 in anti-corrosion, anti-aging, and long life are brought into play, which not only improves the overall performance of the pipe body 1, but also saves costs, and meets the needs of the working environment.

Abstract

The invention relates to the technical field of pipeline conveying equipment, in particular to a composite steel pipe. The composite steel pipe comprises a pipe body, wherein the pipe body is formed by a stainless steel layer and a PE resin layer in a combined mode, the stainless steel layer is located on the outer layer of the pipe body, and the PE resin layer is located on the inner layer of the pipe body. The pipe body is designed to the combined structure of two kinds of materials, the stainless steel layer is located on the outer layer of the pipe body, the PE resin layer is located on the inner layer of the pipe body, the two kinds of materials supplement each other, not only is the good performance of the stainless steel layer reserved, but also the anti-corrosion, anti-aging and long-service life advantages of the PE resin layer are played, the overall performance of the pipe body is improved, cost is saved, and the requirements of the work environment are met.

Description

technical field [0001] The invention relates to the technical field of pipeline transportation equipment, in particular to a composite steel pipe. Background technique [0002] In the chemical, pharmaceutical and other industries, a large number of stainless steel pipes are used for corrosion resistance. In the process of use, in order to make the stainless steel pipe have a certain strength, the pipe wall of the stainless steel pipe is thicker, so that the amount of stainless steel pipe is larger. , leading to higher cost and increased cost, and it is easy to corrode after a long time and has a short service life. Contents of the invention [0003] In order to overcome the disadvantages of low strength, wall thickness, high cost and short service life of existing stainless steel pipes, the invention provides a synthetic steel pipe. [0004] The technical solution adopted by the present invention to solve the technical problem is: a synthetic steel pipe, including a pipe ...
