LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.The coherence of cutter head and plate clamping system guarantees the invariable parameters during the entire milling process; accordingly it ensures the milling quality and lays a good foundation for the success of subsequent welding. Line Steel pipe: the oil, gas or water extracted from the ground can be transported to the oil and natural gas industrial enterprises through pipeline. The pipe line includes two kinds of seamless and welded pipes. The pipe ends have flat ends, threaded ends and socket ends. The connection ways are end welding, coupling connection, socket connection and so on. 316 stainless steel pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and other industrial transmission pipes and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also commonly used to produce all kinds of conventional weapons, barrels, shells, etc. We also have casing in drilling, boiler tube suppliers, petroleum pipe line.
