Great News: Tianjin Yuantai Derun Group Obtains API 5L Certificate
Leave a message
Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd., mainly producing structural steel pipes on their JCOE production line, recently received their API 5L certificate following a thorough preparation and inspection process in mid-May of 2023.
API represents the American Petroleum Institute, where 5L designates the fifth committee, and L stands for line pipe. Thus, the API 5L standard refers to the line pipe standard designated by the American Petroleum Institute's fifth committee.
Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd. creates a range of high-frequency welded pipe products, including welded pipes, square and rectangular pipes, hot-dip galvanized pipes, and line pipes, using high-quality domestic and imported steel materials. Their products meet various standards, including Chinese national standards (GB), American standards (ANSI, ASME, API), and European standards (EN). They also offer non-standard or custom-made products upon request. The products are widely used in the petroleum, chemical, shipbuilding, construction, and mechanical industries.
Their JCOE unit's longitudinally welded steel pipe has high strength, lightweight, good rigidity, and strong deformation capacity, making it particularly suitable for constructing large-span and ultra-high, super-heavy buildings. It is an ideal elastic body that conforms to the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can withstand large deformations and dynamic loads, and is highly industrialized and mechanized.
In the future, the group will continue to study high-strength steel to significantly improve its yield strength to meet the needs of large-span structures and super-tall buildings and to continue to excel in the field of steel structure welded tubes.
Congratulations to Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd. for achieving the API 5L certificate and for their commitment to providing high-quality steel pipe products to the global market.
