Super Super Duplex UNS S32750 Welded Pipes
Piyush steel is the experienced and reputed industry that manufacture and trader of superior quality of pipes. We manufacture a large number of qualities of Super Duplex UNS S32750 Welded Pipes. We maintain huge stocks of pipes which allows us to deliver the products quickly. We have a huge warehouses and sound infrastructure to maintain the quality of our pipes. Owing to its superior characteristics, it is used in thermal power plant, oil and gas plants, etc. as we are the experienced one and working since long duration we are appreciated as leading manufacture as we are serving many of the industries by our great quality products.Super duplex alloy contains austenitic-ferritic alloy that provides good resistance of pitting corrosion and crevice corrosion. It has another chemical composition like molybdenum and chromium content, this provides high tensile strength and exhibits good thermal conductivity it has low thermal expansion.

Manufacturing of welded pipes:
We use latest technology manufacturing tools, and we have extremely competent employees. We have a team of professional for each level right from procurement of raw materials, production, testing, etc. The first step is the procurement of raw material, it is then been heated at high temperature and then it is rolled and cut into the desired shape. We manufacture the pipe in different specifications, sizes, dimensions, shapes, etc. depends on the requirement of various industries.

ASTM A790 Super Duplex Steel S32750 Welded Pipes

Piyush Steel is an experienced and reputable manufacturer and supplier of superior-quality pipes. We manufacture a large number of qualities of Super Duplex UNS S32750 Welded Pipes. Super Duplex Steel UNS S32750 Welded Pipes combine roughly 25% chromium, 7% nickel, and 4% molybdenum in a microstructure that outperforms standard 300-series stainless steel in chloride-rich service. Known globally as 2507 or 1.4410, this grade serves offshore platforms, seawater systems, and chemical processing lines.

What are Super Duplex Steel S32750 Welded Pipes?

These pipes carry the UNS S32750 designation, also sold as SAF 2507 or grade F53. A duplex microstructure splits roughly evenly between austenite and ferrite, giving close to double the yield strength of conventional austenitic stainless steel, at a minimum of 550 MPa. Nitrogen near 0.25–0.3% pushes the Pitting Resistance Equivalent Number above 40.

Features

Yield strength holds at 550 MPa minimum, nearly twice that of a 316L pipe at the same wall thickness. PREN above 40 gives S32750 pitting and crevice corrosion resistance beyond standard duplex 2205. Critical pitting temperature stays above 50°C, a margin that matters in warm seawater intake lines.

Manufacturing Process

Manufacturing starts with a straight-seam or spiral weld joining plate or coil stock, followed by solution annealing at 1050–1100°C to dissolve secondary phases. A rapid water quench locks in the balanced austenite-ferrite ratio before final sizing. Welding under ASTM A928 runs without filler metal on select thicknesses, while heavier sections use matching filler.

Testing & Certification 

Each heat is chemically tested to verify chromium, molybdenum, and nitrogen are within specification, as tiny shifts might drop the PREN value below 40. Ferrite check, hydro test, radiographic weld inspection according to ASTM A790 & A928. Third-party inspection is available through SGS, BV or TUV on request.

Packaging & Delivery

Pipes have end caps to keep weld bevels clean in transit, and bundling and hardwood crating suitable for sea or air freight. Each shipment is documented with heat-specific mill certificates, and delivery deadlines are coordinated against offshore and refinery project schedules.
