S32750 Welded Pipes are chromium and molybdenum alloys with high resistance to pitting, stress corrosion cracking and crevice corrosion. Welded pipes are well known for their string weldability and high strength. These Welded Pipes are resistant to corrosion from organic acids. Also, these Pipes have resistance to inorganic acids and chloride environments. S32750 Welded Pipes are used in offshore platforms, Heat exchangers, Desalination Plants, Mechanical and structural components, sea-water piping and chemical processing industries.
