Duplex Steel Buttweld Fittings

Buttwelded pipe fittings made of duplex steel are extremely strong and malleable. They have remarkable corrosion resistance, particularly against crevice and chloride corrosion. As a result, corrosive areas frequently use these pipe fittings. Pipe elbows made of duplex steel S31803 are a typical style of pipe fitting. The sizes of these Duplex S31803 pipe fittings range from one-eighth inch to 42 inches. Pipe fittings made of duplex steel UNS S32205 have chromium and nickel phases and strong oxidation and corrosion resistance. These pipe fittings and Super Duplex Buttweld Fittings are appropriate for applications demanding high temperatures and corrosion resistance. In addition, they have excellent machinability and low-temperature toughness. By providing the projects of thousands of enterprises with our high-quality products, Shree Viratra Enterprises has realized its aspirations. As producers of Duplex Steel S31803/S32205 Butt Weld Pipe Fittings, we make sure to give you goods that meet the requirements for quality and durability and last longer. Our ASTM A815 Duplex Steel S31803 and S32205 Pipe Elbow prevent some forms of localized corrosion and are essential for applications needing small, flexible seals. Duplex Steel S31803 / S32205 Reducer is superior to regular steel fittings susceptible to chloride stress corrosion cracking in chemical industries at resisting deformities and cracks under high temperatures. It is well known that ASME A182 Duplex Steel S31803 Equal Tee has excellent high toxic resistance and flexibility. We export pipe caps made of ASME SA815 Duplex Steel DIN 1.4462 that fight off hydrogen sulfide, the catalyst for sulfide corrosion cracking in the sour service industry. A wide variety of Duplex Steel ASTM A815 pipe fittings are also available from us, including Duplex Steel S31803 tees, S32205 Duplex End Pipe Caps, Duplex Steel 2205 reducers, Duplex Steel crosses, Duplex Steel S31803 elbows, Duplex Steel S32205 stub ends, among others.
