Structural LSAW Steel Pipe Use In Various Engineering Purposes , Fencing , Scaffolding Etc
LSAW,produced in the mold or molding machine by using double-sided submerged arc welding and flaring from production with raw material. A wide range of the finished product specifications, weld toughness, ductility, uniformity and dense, with a large diameter, wall thickness, high pressure resistance, low-temperature corrosion resistance, etc.. Required steel pipe in the construction of high-strength, high toughness, high-quality, mostly large diameter thick wall LSAW.
1) Longitudinal weld is used for steel pipe and submerged arc welding is used for internal and external welds.
2) After the whole mechanical expansion treatment, the stress inside the steel tube is small and uniformly distributed, which can effectively prevent stress corrosion cracking and has high dimensional accuracy, and is convenient for field welding construction.
3) Using pre-and post-weld technology, the welding process is stable and the quality of the weld is high.
4) Welding is easy to carry out nondestructive testing in the production process, and nondestructive testing can be carried out in the field in the use process.
5) The product specifications range is large, can produce small diameter, large wall thickness, also can produce large diameter, large wall thickness steel pipe.
