This property is particularly noticed when the   Duplex Stainless Steel Pipe   has been exposed to environments that contain corrosive compounds that can cause chloride stress corrosion as well as chloride pitting corrosion. The   Duplex Welded Pipe   also has much higher tensile strength properties as opposed to the standard austenitic stainless steel grades. The   Duplex Steel Pipes   are almost exclusively used in the offshore oil and gas industry. The lower content of nickel used to alloy   Duplex Pipe   is why the metal is economical.
