UNS S31803 / S32750 / S32760 Super Duplex Pipes and Tubings Cold Rolled PE / BE Ends
Duplex stainless steel pipe is austenite-austenite dual phase stainless steel pipe, it is developed for applications that demand high strength and corrosion resistance.
Duplex stainless steel pipe is a cost effective solution for many applications where the 300 series stainless steel pipe are susceptible to chloride stress corrosion cracking. Duplex stainless steel pipe is an idea choice for the applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.
