3. Thickness: SCH5~SCHXXS
4. Service: Cutting, Welding, Fabricated, Customized
ASTM A213 tubing is widely used in high temperature service environments, especially in industries such as power generation, chemical processing and petroleum refining. These tubes have excellent high temperature strength, corrosion and oxidation resistance and good mechanical properties. ASTM A213 / ASME SA213 is a specification established by the American Society for Testing and Materials (ASTM) for seamless ferritic and austenitic alloy steel boiler, superheater and heat exchanger tubes. The tubes provided by our suppliers are subjected to flattening test, expansion test, hydrostatic or non-destructive electrical test, etc.
ASTM A213 Stainless Steel Tubing Applications:
- Power Generation
- Petrochemical Processing
- Chemical Industry
- Oil and Gas Industry
- Heat Exchangers
- Automotive and Aerospace
