Anti-corrosion steel pipe The outer and inner sintered epoxy anti-corrosion steel pipe is an upgraded product based on the outer single-layer polyethylene inner epoxy composite steel pipe. It is currently the most advanced form of steel pipe anti-corrosion for buried long-distance pipelines. The company independently developed the fourth-generation new anti-corrosion production line for large-diameter pipelines. The outer wall adopts the thermal fusion winding process. The bottom epoxy resin, the middle layer adhesive, and the outer polyethylene form a three-layer anti-corrosion layer. The inner wall uses thermal spray epoxy. In the powder anti-corrosion method, the powder is heated and sintered at high temperature and then evenly coated on the surface of the pipe body to form a steel-plastic alloy layer, referred to as steel pipe, (the initials of three-layer English refer to polyethylene and epoxy resin) . It greatly improves the coating adhesion and coating thickness, and enhances the resistance to collision and corrosion. This product obtained the national utility model patent in 2007. Won the National Torch Project in 2016. The steel pipe fills the gap in the best anti-corrosion of domestic steel pipes. The price is almost the same as that of a single-layer polyethylene internally sintered epoxy composite steel pipe, and the corrosion resistance is doubled.
Uses of anti-corrosion steel pipes: The base materials of anti-corrosion steel pipes include spiral pipes, straight seam pipes, seamless pipes, etc., which are widely used in petroleum, chemical industry, natural gas, heat, sewage treatment, water sources, bridges, steel structures, and ocean transportation in my country. Water piling and other pipeline engineering fields.
Pipes (steel pipes) are used in different working environments. In order to slow down or prevent the pipeline from being corroded and deteriorated by the chemical and electrochemical effects of the external medium or by the metabolic activities of microorganisms, coating or lamination is applied to the outer wall of the pipeline. Ethylene is used to achieve pipeline anti-corrosion and extend the service life of anti-corrosion pipes.
Through a review of the annual application history of polyethylene anti-corrosion layers in Europe, although corrosion or stress corrosion cracking can theoretically occur under the peeling off anti-corrosion layer, there has been no case of subfilm corrosion or stress cracking under the peeling off anti-corrosion layer. . At the Mannesmann Institute in Germany, long-term corrosion laboratory experiments have been conducted to simulate the effect of anti-corrosion layer application. The corrosion experiment environment includes soil and water. The test mainly examines the problem of stress corrosion cracking. The experimental anti-corrosion is to place the defective polyethylene anti-corrosion layer steel pipe under corrosion conditions and stress conditions. The corrosion environment is a sandy soil environment containing H, and the temperature is ℃. The pipe-to-ground potential is ~m, the surface of the steel pipes is pretreated in different ways, and all steel pipes are circulated under pressure. At the end of the experiment, there was more or less peeling around the defects in the anti-corrosion layer, but no corrosion was found in the peeling area. Steel pipes without oxygen scale on the surface are prone to stress cracking. Steel pipes with oxide scale are cracked. The cracks have a maximum depth of m, which may be caused by stress corrosion. It is concluded that thorough surface preparation is an effective means of preventing stress cracking.
At present, the application effect of anti-corrosion layer at home and abroad is very good, and there are few reports on the defects caused by its use. The main reported shortcomings include dew point, peeling, cathodic peeling, cathodic protection shielding, peeling and corrosion under the anti-corrosion layer, etc., and most reports of defects still remain in the theoretical speculation stage. For example, the problem of cathodic protection shielding is mentioned in the data. There have been no reported instances of cathodic protection shielding occurring during actual operation of the anti-corrosion layer. Years of practice have shown that as the service life increases, the coating system with the fewest defects is the extruded polyethylene layer structure anti-corrosion system.
