High-cost-performance stainless steel composite pipeline

Abstract

The invention provides a high-cost-performance stainless steel composite pipeline. The pipeline is composed of thin-wall stainless steel, an insulating fixing layer, a pressure-bearing reinforcing layer and an outer anti-corrosion layer which are sequentially arranged from inside to outside, wherein the insulating fixing layer and the outer anti-corrosion layer are connected in a riveted mode through the pressure-bearing reinforcing layer, sanitation and corrosion resistance are guaranteed through the innermost thin-wall stainless steel, the pressure-bearing performance is guaranteed through the pressure-bearing reinforcing layer, the outer anti-corrosion layer guarantees that the pipeline can be directly buried for use, and the insulating fixing layer penetrates through a porous structureof the pressure-bearing reinforcing layer to achieve connection and fixation between the pressure-bearing reinforcing layer and the thin-wall stainless steel and between the pressure-bearing reinforcing layer and the outer anti-corrosion layer are achieved in a riveted mode. According to the stainless steel composite pipeline, the defect that a stainless steel pipe cannot be directly buried is well overcome, the price of the pipeline is lower than that of a common stainless steel pipeline and equivalent to that of thin-wall stainless steel, the pressure bearing performance is consistent withthat of the common stainless steel pipeline and a lining stainless steel pipeline and higher than that of a thin-wall stainless steel pipeline, the comprehensive cost performance is high, and the pipeline is worthy of popularization and application.

Description

technical field [0001] The invention relates to the technical field of stainless steel pipes, in particular to a stainless steel composite pipe with high cost performance. Background technique [0002] In order to improve the quality of drinking water and prevent the secondary pollution of water quality caused by harmful elements in the pipeline, which is harmful to human health, various pipes are constantly emerging. Among them, stainless steel pipes have been more and more widely used in the drinking water industry due to their corrosion resistance, hygiene, non-toxicity, smoothness, and stable material performance. [0003] However, at present, stainless steel pipes mainly include: ordinary stainless steel pipes, thin-walled stainless steel pipes and stainless steel-lined composite pipes. Among them, ordinary stainless steel pipes are very costly to use due to their large wall thickness and heavy weight per unit length. They are rarely used in the market, and cannot be d...

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to provide a cost-effective stainless steel composite pipe, or a cost-effective stainless steel composite pipe with heat preservation function, which solves the defects that traditional stainless steel pipes cannot be directly buried and do not have heat preservation function. The pressure bearing performance is the same as that of ordinary stainless steel pipes and lined stainless steel pipes, and is higher than that of thin-walled stainless steel pipes. The comprehensive cost performance is high and it is worth popularizing and applying
