Introduction
S32750 Super Duplex Stainless Steel Pipe (UNS S32750 / SAF 2507 / EN 1.4410) is a high‑strength, chloride‑resistant duplex stainless steel pipe designed for extreme corrosive environments. This super duplex seamless pipe and welded pipe conform to ASTM A790 and ASTM A789 standards, offering excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in seawater, brine, and acidic media. With high yield strength and outstanding seawater resistance, 2507 super duplex pipe is widely used in oil and gas, offshore platforms, desalination plants, chemical processing, heat exchangers, and power generation. Available in sizes from 1/2″ to 24″ (custom dimensions), SCH40, SCH80, and custom wall thicknesses. As a super duplex pipe supplier and China duplex pipe factory, we supply S32750 seamless pipe and welded pipe with full traceability, polished or pickled surface finishes. ASTM A790 S32750 pipe – your reliable choice for high‑performance industrial piping.

Applications
3.1 Oil & Gas Industry
(S32750 pipe for oil and gas, super duplex pipe for offshore industry, super duplex tubing for pressure vessels)
S32750 pipe for oil and gas – used for offshore flowlines, topside process piping, subsea manifolds, wellhead components, and HP/HT (high pressure / high temperature) gas lines. High strength super duplex steel allows thinner walls, reducing weight and cost.
Super duplex pipe for offshore industry – platform risers, firewater systems, and chemical injection lines. Seawater resistant duplex stainless steel withstands splash zone and subsea corrosion.
Super duplex tubing for pressure vessels – shell and tube heat exchangers, separators, and scrubbers in sour service (H₂S, CO₂, chlorides). Stress corrosion cracking resistant steel prevents failure.
3.2 Marine & Seawater Systems
(duplex stainless pipe for seawater systems, S32750 pipe for marine applications, super duplex pipe for desalination plant)
Duplex stainless pipe for seawater systems – seawater intake piping, cooling water lines, ballast systems, and firewater mains on ships, platforms, and coastal plants. Chloride resistant stainless steel pipe is immune to pitting and crevice corrosion in warm seawater.
S32750 pipe for marine applications – propeller shafts, rudder components, and seawater pump casings. Excellent corrosion resistance duplex pipe outlasts super austenitics (6Mo).
Super duplex pipe for desalination plant – brine recirculation lines, high‑pressure reverse osmosis (RO) feed piping, and evaporator tubing in multi‑stage flash (MSF) plants. S32750 seamless pipe handles hot concentrated brine.
3.3 Chemical & Heat Exchanger Industry
(S32750 pipe for chemical industry, duplex pipe for heat exchanger, super duplex pipe for industrial equipment)
S32750 pipe for chemical industry – piping for acetic acid, phosphoric acid, formic acid, and chlorine dioxide. High performance duplex stainless steel resists both reducing and oxidizing environments.
Duplex pipe for heat exchanger – shell‑and‑tube heat exchangers, condenser tubes, and cooling coils in chemical and petrochemical plants. High yield strength stainless steel pipe allows thinner tube walls for improved heat transfer.
Super duplex pipe for industrial equipment – reactor jackets, distillation column feed lines, and agitator shafts.
3.4 Power Generation & Industrial Applications
(duplex steel pipe for power plant, S32750 pipe for industrial equipment)
Duplex steel pipe for power plant – FGD (flue gas desulfurization) scrubber piping, condensate lines, and cooling water systems in coal, gas, and nuclear plants. Pitting resistant stainless steel pipe withstands wet chlorides and low pH.
S32750 pipe for industrial equipment – pressure vessel nozzles, tank outlet piping, and mixer feed lines.
