A large amount of seawater is indispensable for an oil gas plant, an electric power plant and a seawater desalination plant. Cast pumps made of niresist material have been mainly used in this field, especially a large-size pump, but it has problems with long time processing, huge weight and stress corrosion cracking.
Combination of NSSC duplex stainless steel [S32750,S31803] with excellent corrosion resistance & high-strength and canning process using plates & sheets allowed weight saving, long service life, cost saving and short time processing.
Canning pumps using NSSC duplex stainless steel have been already widely used in the world.
