Description
Product Name: Welding Reducer (Stainless Steel, Duplex Steel 2205). Raw Materials: Made of UNS S32205/S31803 duplex stainless steel, which features excellent corrosion resistance and high strength. Production Process: Pipe blanks or steel plates are formed via hot pressing or cold pressing. After forming, solution heat treatment (water quenching at approximately 1050-1100°C) is carried out to optimize the metallographic structure and corrosion resistance. Subsequently, precise machining is performed to guarantee the precision of port dimensions and bevels. Finally, pickling and passivation treatment is conducted to form a passivation film, followed by rigorous physical, chemical and non-destructive testing. Application Fields: Particularly suitable for harsh corrosive environments, including pipeline systems in chemical industry, petrochemical industry, offshore platforms, seawater desalination, papermaking, flue gas desulfurization and other industries, for connecting pipelines with different diameters. Temperature and Pressure Resistance: Duplex Steel 2205 boasts favorable high-temperature performance, with a long-term service temperature range from about -50°C to +300°C and a higher short-term temperature resistance. It has high pressure resistance, complying with GB/T12459-2017 standard. Its pressure rating is related to wall thickness, making it applicable to high-pressure systems.
