Ubique Alloys Pvt. Ltd is a well-known company that manufactures and trades Duplex Steel S31803 Pipes / Duplex Steel S32205 Pipes, which is readily welded by all common methods including submerged arc. Duplex Steel S31803 Seamless Pipes has supplanted this stabilized grade for applications involving only welding or short time heating. Duplex Steel S32205 Welded Pipes is not subject to weld decay (inter-granular corrosion) when exposed to mildly corrosive environments. Duplex Steel S31803 Round Pipes is used in stack liners, boiler casings, welded pressure vessels, jet aircraft components, radiant super-heaters, bellows and oil refinery equipment, etc. Duplex Steel S32205 Square Pipes offers resistance to organic acids and some inorganic acids that is excellent. Duplex Steel S31803 Rectangular Pipes is also used in Chimney and Stack Liners, Storage Tanks, Bellows, etc. Additionally, it is often chosen Duplex Steel S32205 Electropolish Pipes for its increased resistance to creep and rupture, as it may be susceptible to stress corrosion cracking.

Copper back-up plates of Duplex Steel S31803 Hexagonal Pipes for faster heat rejection are functional, whereas to avoid cracks in the solder metal, it is not allowed to surface-fuse the copper back up plate. In fact two or three times as much energy is required to forge Duplex Steel S32205 Bush Hex Pipes as is required for carbon and alloy steels. In addition, Duplex Steel 2205 Pipes can also be used for anti-sensitization and inter-granular corrosion.
