JCOE steel pipe production line of Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd. mainly focuses on the production of structural steel pipes. After sufficient preparation, the Group was audited by API in the middle of May 2023 and has recently obtained the certificate of certification of API Spec. 5L standard.

API is the abbreviation of American Petroleum Institute, 5 refers to Committee 5, L refers to line pipe. So API Spec. 5L is the standard for line pipe referred to by the American Petroleum Institute Committee 5.

Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd. manufactures various kinds of high-frequency welded pipes, square and rectangular pipes, hot galvanized pipes, line pipes and other welded pipes with domestic and imported high-quality steel raw materials. The products can be produced according to the national standard GB, American standard ANSI, ASME, API, European standard EN and other standards, can also be customized according to customer requirements of non-standard or special purpose products. Our products are widely used in petroleum, chemical, shipbuilding, construction, machinery and other industries.

Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd. JCOE unit of production of straight seam steel pipe, which is characterized by high strength, light weight, good overall stiffness, deformation ability, so it is used for the construction of large-span and ultra-high, ultra-heavy building is particularly suitable; is an ideal elastomer, in line with the basic assumptions of the general engineering mechanics; the plasticity of the material, toughness, can be a large deformation, and can be very good to withstand the power loads; the degree of industrialization is high, and a high degree of mechanization of the production.

In the future, the Group will continue to delve into high-strength steel in terms of structural steel LSAW pipes, and greatly increase its yield point strength to meet the needs of large-span structures and ultra-high-rise buildings.
