Welded steel pipe according to the production process can be divided into longitudinally submerged arc welded steel pipe and steel pipe. Submerged arc welded steel pipe according to the different forming method is divided into UOE, RBE and JCOE steel pipes. Here are the most common and high frequency welded steel pipe forming process of submerged arc welded pipe. Hebei Tianze Pipeline Company Limited production of LSAW pipe, JCOE pipe by forming a weld, double submerged arc welding process, specifications range from 325mm-1420mm. When the LSAW pipe diameter greater than the standard 914.4 allows two straight seam welding pipe. LSAW pipe products execute GB/T3091-2008 low-pressure fluid pipe standard, GB/T9711.1 (2) -1997 petroleum and natural gas pipeline implementation of standards, ASTM A252 steel pipe welding structure of American standard. The production process of LSAW pipe flexible production within the scope of any specifications and wall thickness, high production efficiency. LSAW advantage is that can produce high frequency steel pipe, spiral steel pipe, seamless steel pipe production are not even specifications. LSAW pipe production cost will be higher than the high frequency steel pipe, spiral steel pipe, seamless steel pipe, but rather than price space. LSAW can produce high frequency steel pipe and spiral steel pipe can not produce material, such as high frequency steel pipe is usually produced in common specifications than domestic, batch production inventory, usually made of Q235B/Q345B other hard steel material of high frequency equipment and equipment at home is not the production of spiral. LSAW pipe in heavy steel structure engineering and pipeline engineering in China, has been widely used in foundation piling. Welded steel pipe commonly used materials Q235A, Q235B, 16MN, 20#, Q345B, L245, L290, X42, X46, X60, X80 etc.. Hebei Tianze pipeline limited company welcome you
