Cutting Method of Anti-Corrosion Steel Pipe

Anti-corrosion steel pipe refers to a 3-layer structure polyolefin coated anti-corrosion steel pipe, which is a commonly used anti-corrosion pipeline in China. Let's take you to have a deeper understanding of anti-corrosion steel pipes. First, the anti-corrosion structure of anti-corrosion steel pipes and then the advantages of anti-corrosion steel pipes.

1. Anti-corrosion structure of anti-corrosion steel pipes

Anti-corrosion generally consists of a 3-layer structure: the first layer of epoxy powder (FBE>100um), the second layer of adhesive (AD) 170~250um, and the third layer of polyethylene (PE) 2.5~3.7mm. In actual operation, the three materials are mixed and integrated, and after processing, they are firmly combined with the steel pipe to form an excellent anti-corrosion layer. Its processing methods are generally divided into two types: winding type and round mold coating type.

2. Advantages of anti-corrosion steel pipes

Ordinary steel pipes will be severely corroded when used in harsh environments, which will reduce the service life of the steel pipes. The service life of anti-corrosion and thermal insulation steel pipes is also relatively long. Generally, they can be used for about 30-50 years. Correct installation and use can also reduce the maintenance cost of the pipeline network. Anti-corrosion and thermal insulation steel pipes can also be equipped with an alarm system to automatically detect pipeline leakage faults, accurately know the fault location and automatically alarm.

Anti-corrosion and thermal insulation steel pipes have good thermal insulation performance, and the heat loss is only 25% of traditional pipes. Long-term operation can still save a lot of resources and significantly reduce energy costs. It also has strong waterproof and corrosion resistance, and does not require a trench. It can be directly buried underground or in water. It is also simple and quick in construction, and the comprehensive cost is relatively low. It also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in frozen soil in certain environments.
