The Super Duplex Steel UNS S32760 Pipes have been characterized as having impressive corrosion resistance, mechanical strength and performance in the hostile environment. We are the supplier and exporter of high quality UNS S32760 pipes which are produced to high standards of international standards in Metinox Overseas. This grade of super duplex is a balanced austenite ferrite microstructure with added chromium, molybdenum and nitrogen, resulting in higher resistance to pitting, crevice, and stress corrosion cracking. Super Duplex S32760 Pipes are much more efficient in terms of durability under moisture and chlorides and other adverse industrial environments as compared to the traditional carbon steel, and thus their use is usually preferred in high-pressure services.
The use of UNS S32760 seamless, as well as welded, pipes is extensive in the oil & gas industry, petrochemical industry, shipping industry, food industry, as well as in the power industry. The iron alloy is known for its outstanding resistance to rusting, as well as staining, but is sensitive to parameters such as oxygen concentration, salinity, temperature, and concentrations of chemicals. The use of these pipes is also an important aspect in equipment, pressure tanks, heat exchangers, structural parts, as well as heavy machinery, whereby high strength, as well as high resistance, is the primary factor. Due to the ability of the iron alloy to withstand highly pressurized, as well as highly acidic, environments, the Super Duplex S32760 pipes can withstand highly challenging environments, provided that the correct selection, as well as standards, are followed.

Manufacturing Process of Super Duplex Steel UNS S32760 Pipes
Super Duplex Steel UNS S32760 pipes are made through modern technologies in order to make sure that they are of great strength, corrosion resistance, and reliability in severe service conditions. All manufacturing processes are closely observed to ensure that there is the right microstructure and that performance is uniform.
Seamless Pipe ProductionIt starts with high-quality alloy billets, which are heated, and holes are pierced in their middle to form hollow regions. These parts are then subjected to hot forming and finishing processes in order to obtain very tight tolerances, smooth finishes and great mechanical integrity.
Welded Pipe ManufacturingIn welded pipes, Super Duplex steel plates or coils are rolled to tubular surfaces and welded together by means of controlled welding. Optimization of the welding process is done so that the joint offers equal strength and corrosion resistance as the parent material.
Heat Treatment ProcessSolution annealing is done after forming or welding of the pipes. This heat technology increases toughness, eliminates remaining stresses, and increases pitting resistance and stress corrosion cracking resistance.
Inspection and Testing
The pipes are checked in terms of quality, such as dimensional checking, mechanical checking, and non-destructive testing, to check their adherence to the international standards.
