JIS G3459 Industrial Piping Austenitic Stainless Steel Welded Pipes

Austenitic stainless steel fluid-carrying welded pipes are manufactured via cold working processes with automatic welding. Key specifications and details are as follows: – Outer Diameter (OD) : 12-3000 mm（修正原文筆誤「3000m」為行業標準單位「3000mm」） – Wall Thickness : 1.00-30.96 mm – Surface Treatment : Acid-washed (removes oxide scale, weld residues, and surface impurities; enhances corrosion resistance and surface cleanliness-critical for maintaining fluid purity and preventing leakage in large-diameter fluid conveyance systems) – Application Scope : Suitable for pipelines transporting liquids, particulates, and gases. Widely used in chemical processing, boiler systems, power generation, food processing, and other industrial fields requiring reliable and corrosion-resistant fluid transfer.
