Construction Large Diameter High Strength 0.8 - 12.75 Mm Hot Rolled Spiral Welded Round Carbon Steel Pipe
It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip according to a certain spiral angle (called forming angle) into a tube blank, and then welding the tube seam together. It can be made with a narrower Strip steel produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness, and the welded pipe shall be ensured that the hydraulic test, the tensile strength of the weld and the cold bending performance must meet the requirements.
Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetallic composite pipes, coatings and coating pipes for saving precious metals and meeting special requirements. . Stainless steel tubes are available in a wide variety of applications, with different technical requirements and different production methods. The outer diameter of the currently produced steel pipe ranges from 0.1 to 4500 mm and the wall thickness ranges from 0.01 to 250 mm. In order to distinguish the characteristics, the steel pipes are usually classified as follows.

Stainless steel welded pipe production process:
Raw materials - slitting - welding pipe - trimming - polishing - inspection (printing) - packaging - shipping (into the warehouse) (decorative welded pipe).
Raw materials--striping--welding pipe--heat treatment--correction--straightening--trimming--pickling--hydraulic pressure test--inspection (printing)-packaging--shipping (warehouse) (Pipe pipe industrial piping pipe).
