Cangzhou Steel Pipe Group (CSPG) Co., Ltd.

The main production standard of the pipeline with straight seam is gb9711, which is adopted by api5l overseas. It also gives a clear range of the tensile strength, yield strength, elongation, yield ratio, impact resistance and heat treatment status of the pipeline with straight seam. The materials of straight seam pipe are mainly x42,x46,x52,x56.x70 and corresponding l series. According to the production process can be divided into high frequency straight seam steel pipe and submerged arc welding straight seam steel pipe. The submerged arc welding straight seam steel pipe is divided into UOE, RBE and JCOE steel pipe according to its different forming modes. LSAW Line Pipe shall be subjected to mechanical performance test, flattening test and flaring test and shall meet the requirements specified in the standard. Mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction. For liquid transport: water supply and drainage. Gas transportation: gas, steam, liquefied petroleum gas. For structure: for pile driving pipe, as a bridge; Wharf, road, building structure pipe, etc.
