Flanges welded with Fittings
Duplex steel pipe with flange is a type of pre-fabrication pipe spool. Pre-fabrication pipe spools come pre-assembled, which means they are pre-cut, fitted, and welded, minimizing the need for on-site fabrication, assembly, and welding. Duplex stainless steel flanges and pipe are made of a high-strength and high-corrosion-resistant alloy. Duplex s31803, 2205, 2507 contain a combination of austenitic and ferritic microstructures. Providing superior strength, durability, and corrosion resistance in applications where conventional materials may fail.
Duplex Stainless Steel Pipes And Flanges Standard:
- ASTM A790: Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe
- ASTM A928: Standard Specification for Ferritic/Austenitic (Duplex) Stainless Steel Pipe Electric Fusion Welded with Addition of Filler Metal
- ASTM A182: Standard Specification for Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service
