Home > Duplex Steel > Duplex Steel Pipe
Duplex Steel Pipes are made from duplex stainless steel, a unique material blending both austenitic and ferritic microstructures. This combination grants these pipes remarkable strength and resistance against corrosion, rendering them perfect for challenging environments found in chemical processing, oil and gas, and marine engineering industries. Renowned for their durability, high tensile strength, and ability to withstand pitting and crevice corrosion, duplex steel pipes stand as a dependable option for critical applications subjected to harsh conditions.
