GNEE is a leading supplier of ASTM A790 UNS S32205 pipes, offering a wide range of sizes and specifications, including types with mirror polished, plain end, beveled, and threaded connections. GNEE supplies high-quality, dimensionally accurate A790 UNS S32205 welded and seamless pipes with excellent surface finish.
Due to its higher yield strength, thinner UNS S32205 duplex stainless steel pipes and S32205 duplex stainless steel SCH40 pipes can be manufactured, resulting in significant weight reduction. This makes UNS S32205 duplex composite pipes, UNS S32205 duplex polished pipes, and UNS S32205 electric resistance welded pipes common choices for structural applications and pressure vessels.
According to the ASTM A790 standard, UNS S32205 welded and seamless pipes conform to ANSI B36.19 standards, with outside diameters ranging from NPS 1/8 to NPS 30, and wall thickness schedules including Sch 5S, SCH10S, SCH40S, and SCH80S. Other sizes can be customized according to customer requirements. The roundness tolerance and wall thickness tolerance of ASTM A790 pipes comply with the ASTM A999 standard.
