Recently, steel pipes were exclusively supplied by Shagang Jinzhou Pipeline Co., LTD. Jiaozhou Bay undersea natural gas pipeline project in the sea section starts welding, marking the construction of the sea section of the project in an all-round way.

The project has a total length of 72 kilometers, of which the submarine section reaches 12 kilometers. It is the longest urban gas pipeline involving the sea in China and the first large-scale land-to-sea "directional drilling" natural gas pipeline in China. The engineering section of the pipe into the sea has a very high technology "threshold", not only need tensile, compressive, scouring resistance, corrosion resistance and other characteristics, to meet the complex welding process, especially for pipeline toughness at low temperature, single pipe length, guide bending center diameter, steel pipe ovality accuracy are put forward such as the highest standard requirements.

Shagang has a perfect pipeline steel product system and has successively developed pipeline steel for submarine oil, x70/80 pipeline steel with large wall thickness and high toughness, PIPELINE steel with H2S corrosion resistance, pipeline steel with large deformation resistance and other products. Shagang has become the first company in China to complete the strain-based design of an X80 pipeline steel plate with large deformation resistance. Shagang X60 and above pipeline steel was awarded the national manufacturing single champion product. Shagang pipeline steel is widely used in the second and third lines of the “West-east Gas Transmission Project”, the fourth line of Shanxi and Beijing, the eastern line of China and Russia, local pipe network projects, foreign oil pipeline projects and so on. It has a good reputation among users and a large market share in the industry.

Shagang Jinzhou Pipeline Co., Ltd. is a professional manufacturer of straight seam submerged arc welded pipe with the advantage of integrated production of plate and pipe, and its technological process has reached the international advanced level. In recent years, Shagang Jinzhou Pipeline fully implemented the new development concept, continued to improve the technical level, to create a series of high-quality, high-customer satisfaction "ace products", It has successively won the honors of Jiangsu High-tech Enterprise, Suzhou Innovative Leading enterprise, Suzhou big straight seam Submerged arc welded Steel Pipe Intelligent manufacturing Workshop, Suzhou Phase controlled Ultrasonic Non-destructive Testing Engineering technology Research Center and so on.
