Product name: ERW Steel PipeStandard: ASTM A53Size: 450NB X 12mApplication: Industrial energy construction project

The high-frequency welding process of straight seam steel pipes is completed in high-frequency welded pipe units. High-frequency welded pipe units usually consist of roll forming, high-frequency welding, extrusion, cooling, sizing, flying saw cutting, and other components. The front end of the unit

Corrosion in steel pipes occurs because metals are sometimes susceptible to chemical reactions that weaken them. Once the metal is weakened, it becomes susceptible to rust and can form cracks and holes, which is a big problem. Therefore, it is vital that steel pipes are protected against corrosion,

As a terminal technology product in the steel pipe industry chain, anti-corrosion steel pipes have always occupied a very important position in the industry. In recent years, with the development and application of new anti-corrosion technologies for steel pipes, anti-corrosion steel pipes have beco
