TOKOTECH can provide different size of s32750 duplex steel welded pipes. S32750/2507 duplex steel welded pipe has excellent corrossion resistance, especially the media environment is relatively harsh, such as seawater, high chloride ion content) conditions,it’s corrosion resistance is significantly better than ordinary austenitic stainless steel.
