Welded pipe is a round pipe welded by steel plate, which is divided into high-frequency resistance welded pipe (ERW welded pipe), straight seam arc welded pipe (LSAW), and spiral welded pipe. In electrical engineering, it is represented by "SC", which can be used as a water gas pipe or a threading pipe, which is relatively thick.
Products Description
It is widely use in many fields like the following:
Line pipe, that is, wire pipe, is relatively thin, denoted by "T", and can only be used as a threading pipe. ERW pipe is a "high-frequency resistance welded steel pipe", which is different from the ordinary welded pipe welding process, the weld is melted by the base metal of the steel strip body, and the mechanical strength is better than the general welded pipe.
ERW means resistance welding, resistance welding has the characteristics of high production efficiency, low cost, material saving, easy automation, etc., so it is widely used in aviation, aerospace, energy, electronics, automobiles, light industry and other industrial sectors, is one of the important welding processes.
ASTM ERW Welded Steel Pipe Characteristics:
High strength: The strength of welded steel pipe is higher than that of ordinary steel pipe, which can withstand greater pressure and weight.
2. Good corrosion resistance: the surface of the welded steel pipe is treated, which can prevent corrosion and oxidation and prolong the service life.
3. High welding quality: the welded steel pipe adopts high temperature welding technology, which has high welding quality, firm weld seam, and is not easy to crack.
4. High dimensional accuracy: welded steel pipe has high dimensional accuracy and can meet the requirements of various projects.
5. Convenient construction: welded steel pipes can be cut and connected as needed, which is convenient for construction and can save time and cost.
