Ss 2205 saf 2507 super duplex stainless steel pipe and tube
Super Duplex Stainless Steel Pipe & Tube - S32205 (UNS S32205) / S32750 (UNS S32750)
Baobin Group's super duplex stainless steel pipes and tubes are engineered for demanding applications requiring exceptional corrosion resistance and mechanical strength. These duplex stainless steel pipes are widely used in oil & gas, chemical processing, desalination plants, and offshore environments where standard stainless steels fall short.
Key Applications
- Oil and gas production (especially in sour service environments)
- Chemical processing equipment
- Seawater handling systems
- Desalination plants
- Offshore platforms and subsea applications
- Pressure vessels and heat exchangers
