s32750 super duplex Forming
Seamless pipe (SMLS): Usually adopts hot extrusion + cold drawing/cold rolling process, suitable for high pressure and high safety level occasions. Pay attention to the surface finish of the inside and outside.
Welded pipe (WELDED): Usually adopts automatic welding (TIG, Laser, Plasma) + online solution treatment. Weld quality is the core, requiring the weld to be equivalent to the parent material (WMQT). Check the weld internal and external height control and weld uniformity.

super duplex uns s32750 Corrosion resistance
saf 2507 Anti-pitting and crevice corrosion
PREN value (pitting equivalent) ≥43, much higher than 316L (PREN~25) and ordinary duplex steel S32205 (PREN~35), and outstanding performance in chloride ion media.
2507 super duplex stainless steel Resistance to stress corrosion cracking (SCC)
No risk of cracking in oil and gas environments containing H₂S/CO₂, ensuring the safety of high-pressure pipelines.
2507 stainless steel Resistance to uniform corrosion
The corrosion rate in boiling hydrochloric acid is only 0.02 mm/y, which is better than 316L (6.94 mm/y).
Application of 2507 alloy pipe
Oil and gas: submarine pipelines, downhole tools for acid gas wells.
Chemical equipment: sulfuric acid reactors, phosphoric acid evaporators, pickling equipment.
Nuclear industry: containers and pipelines for nuclear waste treatment systems.
Marine engineering: seawater desalination devices, heat exchangers.
Environmental protection: key components of flue gas desulfurization (FGD) systems.
