lsaw steel tube manufacturer China tianjin Yuantai Derun(oem odm obm)
JCOE Steel Pipe（LSAW tube）
JCOE is straight seam double-sided submerged arc welded pipe, LSAW steel pipe can be divided into high frequency LSAW steel pipe and submerged arc welded LSAW JCOE steel pipe according to the production process. Submerged arc welded straight seam steel pipe according to its different forming methods are divided into UOE, RBE, JCOE, LSAW steel pipe, etc. JCOE steel pipe production process is simple, high production efficiency, low cost, the development of faster.
JCOE is one of the forming methods of LSAW steel pipe and one of the equipment. GB/T3091-2008, GB/T9711.1-2008 are generally used in China, and the international standard is API-5L.JCOE steel pipe is mainly based on double-sided submerged arc welding production process, and the products are bended, seamed, internally welded, externally welded, straightened, and flattened in many processes to meet the requirements of the relevant standards.
