To be a top metal materials supplier and add honor to China's manufacturing.
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 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.
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.
