Anti-corrosion pipe manufacturer
Cangzhou Tianyuan Anti-corrosion Engineering Co., Ltd. Anti-corrosion steel pipe usage: Anti-corrosion steel pipe base materials include spiral pipes, straight seam pipes, seamless pipes, etc., which are widely used in petroleum, chemicals, natural gas, Heating, sewage treatment, water sources, bridges, steel structures, marine water piling and other pipeline engineering fields.
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 maximum depth of the crack is 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 structural anti-corrosion system.
