Spiral welded pipe is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle), and then welding the pipe seam. It can be made with a narrower strip Steel produces large diameter steel pipes.

Precision tube is a high-precision, high-brightness seamless steel tube produced by cold drawing or cold rolling.

​The manufacturer of seamless steel pipe tells you that the frictional resistance between the surface of the seamless steel pipe and the injection mold is too large and drawing cannot be carried out. To solve the problem, the seamless steel pipe manufacturer tells you that a high-density metal material soap film is produced on the outer surface of the seamless steel pipe to reduce the friction between the seamless steel pipe and the injection mold, thereby ensuring the smooth development of the drawing.

The manufacturer of seamless steel pipe tells you the three advantages of thick-walled seamless pipe:
1. Corrosion resistance:
Seamless steel pipe manufacturers tell you that most thick-walled seamless pipe products require good corrosion resistance. Thick-walled seamless pipes are similar to Class I and Class II tableware, kitchen utensils, water heaters, water dispensers, etc.

With the adjustment of the national macro policy, China's seamless steel pipe trade industry profits from January to May this year decreased by 56.9%, large and medium-sized seamless steel pipe enterprises in July net loss of 1.984 billion yuan, in August, the whole industry faced losses. Many problems existing in the traditional ......
