Astm A312 Tp 304 Welded Stainless Steel Tube
This ASTM A312 TP304 welded stainless steel tube is an austenitic grade product with 18% chromium and 8% nickel composition, supplied by Foshan Kuanyu Stainless Steel Co., Ltd. from Foshan, Guangdong. The tube is available in sizes ranging from 1/4 inch to 84 inches in diameter, with wall thickness options including SCH-5S, SCH-10S, SCH-40S and SCH-80S, conforming to ASME B36.19M and B36.10M dimensional standards. It is designed for high-pressure and hygienic applications where corrosion resistance and weldability are critical.
The material meets ASTM A312 specifications for welded austenitic stainless steel pipe, with typical mechanical properties including a tensile strength of 515 MPa minimum and yield strength of 205 MPa minimum for annealed condition. The inner and outer surfaces are pickled and passivated to remove contaminants and enhance corrosion resistance, typical for 304 grade tubes used in chemical processing, water treatment and food-grade environments. Standard mill test certifications are provided for traceability and quality assurance.
Primary applications include chemical engineering, industrial production and sewage treatment systems where durability under corrosive conditions is required. Buyers typically source this product for pipeline projects in oil and gas, water treatment plants and food processing facilities. The tubes are exported globally from loading ports in Foshan, Guangzhou or Shenzhen, with delivery terms available under FOB, CFR, CIF or EXW incoterms. Bulk orders are packaged in wooden crates or bundles with protective coatings to prevent damage during transit.

Sourcing Astm A312 Tp 304 Welded Stainless Steel Tube from Foshan Kuanyu Stainless Steel Co., Ltd. - China Import Guide
Before ordering, verify the exact outer diameter, wall thickness schedule, and surface finish to ensure compatibility with your pipeline system. Confirm that the tube meets ASTM A312 and ASME B36.19M standards, as these define critical dimensions and tolerances for industrial applications. Request mill test certifications to validate the material composition and mechanical properties, particularly for high-pressure or corrosive environments.
Negotiate logistics details such as the loading port (Foshan, Guangzhou, or Shenzhen) and incoterms (FOB, CFR, CIF, EXW) to align with your supply chain requirements. Clarify packaging options, as the tubes are typically shipped in wooden crates or bundles with protective coatings to prevent damage. Discuss lead times, as these may vary based on order volume and production schedules, especially for large-diameter or custom-specification tubes.
Conduct quality checks upon receipt to ensure the tubes meet specified dimensions, surface finish, and mechanical properties. Inspect for defects such as cracks, pits, or inconsistent wall thickness, which could compromise performance. Request additional testing, such as hydrostatic or non-destructive testing, if the application demands higher assurance of structural integrity. Ensure all documentation, including mill test certificates and compliance reports, is provided and reviewed before acceptance.
