Super Duplex S32550 Pipes are premium stainless steel pipes engineered for the most demanding industrial environments. They possess a balanced duplex microstructure of ferrite and austenite, providing exceptional tensile strength, corrosion resistance, and toughness. This combination makes them highly suitable for applications where reliability and durability are critical.
Metal Tubular Products is recognized as a leading global stockist and supplier of Super Duplex S32550 Pipes. Our extensive inventory includes seamless (SMLS), ERW, LSAW, and SSAW pipes, available in various diameters, wall thicknesses, and schedules. This ensures we can meet the diverse needs of projects across the oil & gas, chemical, and offshore industries.
These pipes are widely used in environments that involve high chloride exposure, seawater handling, and chemical processing. Super Duplex S32550 Pipes offer superior resistance to pitting, crevice corrosion, and stress corrosion cracking, making them ideal for desalination plants, heat exchangers, marine equipment, and chemical reactors..
Metal Tubular Products ensures that each S32550 pipe meets rigorous quality standards. Every pipe undergoes detailed inspection and testing, including chemical composition analysis, hydrostatic testing, and verification of mechanical properties. This ensures full compliance with international standards such as ASTM A789 / ASME SA789, giving customers confidence in product reliability.
