Flowtera Pipe
1 / 5
Duplex stainless steel pipes exhibit exceptional durability, high strength, and excellent corrosion resistance. These properties make them a preferred material for demanding applications in the oil and gas, chemical, and petrochemical industries. Combining austenitic and ferritic phases, this alloy maintains toughness at cryogenic temperatures and retains mechanical integrity in aggressive environments up to 700°C.
