Shanghai Tianyang Steel Tube Co., Ltd. is a specialized manufacturer based in Shanghai, China, focused on the production of high-precision seamless steel tubes and composite piping materials. Founded in the early 2000s, the company has developed a distinct operational focus within the heavy industrial supply chain, particularly servicing the marine engineering, shipbuilding, and offshore energy sectors. Its headquarters and primary facilities are located in the Fengxian District, with additional manufacturing capabilities established in Zhejiang Province to support expanded production capacities.
In the maritime domain, the company is recognized for its compliance with rigorous international standards required for vessel classification and safety. It has secured manufacturing approvals from a wide array of major classification societies, including the China Classification Society (CCS), American Bureau of Shipping (ABS), Lloyd’s Register (LR), Bureau Veritas (BV), and DNV, among others. These certifications validate the technical integrity of its piping solutions for use in critical shipboard applications, such as hydraulic systems, boilers, and heat exchangers, where reliability under high pressure is non-negotiable.
The company’s industrial activities center on advanced metal processing techniques, such as cold drawing and cold rolling, to achieve the tight tolerances defined by DIN and EN standards. Beyond standard seamless tubes, Shanghai Tianyang has diversified its engineering capabilities to produce industrial-grade bi-metal clad pipes and high-polymer composite materials. These products are designed to address specific challenges in offshore environments, including corrosion resistance and structural durability in harsh marine climates.
The manufacturer sources raw materials from major domestic steel producers, integrating these inputs into a supply chain that exports to markets across Europe, the Americas, and Asia. By maintaining strict adherence to quality management systems and pressure equipment directives, Shanghai Tianyang functions as a verified supplier for global projects involving marine machinery, wind power installations, and petrochemical infrastructure. The firm’s continued investment in research and development, often in collaboration with technical institutes, supports its ability to deliver specialized piping components that meet the evolving specifications of the global maritime and offshore industries.
