To be a top metal materials supplier and add honor to China's manufacturing.
Ansteel’s self-developed high-strength and tough steel has been successfully supplied to China’s first 36-inch deep-sea tension leg platform tendon steel pipe project, filling a domestic gap and achieving world-class performance.
Yangtze Steel Group has completed factory inspection and shipment of seamless steel pipes made of 30CrMnSiA steel (dimensions: 140×20×8500 mm and 89×19 mm), demonstrating its commitment to quality for overseas customers through rigorous quality inspections and end-to-end supervision.
As seamless steel pipes, being made of iron-based materials, are prone to electrochemical corrosion in their operating environment, it is essential to employ corrosion protection measures such as coatings and cathodic protection to extend their service life and ensure safety. The selection of corrosion protection methods should be based on a comprehensive optimisation of the characteristics of the medium, environmental conditions and life-cycle costs.
This article explains the situations in which seamless steel fire-fighting pipes must be retested in pressure pipelines, the conditions under which retesting can be waived, common testing items, and the on-site acceptance process.
This article compares the key differences between the API 5L and API 5CT steel pipe standards in terms of intended use, performance, and application scenarios, providing a practical reference for technology selection in the oil and gas industry.
This article comprehensively reviews the classification system of seamless steel pipes by material, details the characteristics of different materials such as carbon steel, alloy steel and stainless steel, and analyzes their applicable scope and material selection points in fields such as structure, fluid transportation, boiler, petrochemical and precision machinery.
Shanghai's Pudong New Area is piloting a "thick-walled stainless steel pipe + fully automated self-fusion welding" process to solve the problem of gas system renovation in old residential areas.
Q235 galvanized steel pipes, with their excellent strength, superior hot-dip galvanized corrosion resistance, and high cost-effectiveness, are a reliable material well-suited for greenhouse structures.
This article provides a detailed account of the complete production process for hot-rolled seamless steel pipes, which involves transforming solid billets into hollow finished tubular products through three core deformation processes—heating, piercing, and rolling—followed by subsequent finishing and inspection.
