Why should steel pipes anticorrosive?As the name implies, steel pipes anticorrosive is to prevent steel pipes from corrosion and reduce the service life.PE anticorrosive steel pipe
3PE anticorrosive steel pipe refers to the 3 -layer structure of polyolefin coating (MAPEC) external anticorrosive steel pipes. It is a commonly used anticorrosive pipe in China. A
After the seamless steel pipe manufacturing is completed, after the acid washing, according to customer requirements, galvanized treatment, there are generally three types of galva
How to classify it according to the working method of the spiral steel pipe? The spiral steel pipe irrigation system can be divided into mobile, semi -fixed and fixed. 1. Mobile. I
Zinc is easily dissolved in acid and can also dissolve in alkali, so it is called a sexy metal. Zinc almost does not change in dry air. In humid air, zinc surface will generate den
The purpose of the ultimate heat treatment is to improve mechanical properties such as hardness, abrasion resistance and strength. (1) quenching The quenching has surface quenching
The hot -dip galvanized pipe causes the melting metal to react with the iron -based body to generate the alloy layer, which combines the substrate and the coating. The hot -dip gal
Nowadays, many spiral pipe manufacturers have not reached standard regulations on the surface through the production and processing of spiral pipes, but there are still successive
Spiral buried arc tube rolling tube forming method is the first roll molding method At the time of the upper volume, the bottom surface of the steel pipes of various specifications
The production process of spiral steel pipes is simple, the production efficiency is high, and the welded pipe with a large production pipe diameter can also be used with different
According to the welding method, it can be divided into arc welded pipes, high -frequency or low -frequency resistance welded pipes, gas welding pipes, furnace welding pipes, and B
Because the spiral tube is stacked outdoors, and most of them are buried on the ground when used, it is easy to corrode and rust. In order to ensure the smooth flow of the pipeline
