The Duplex Steel Pipe gets its name from the dual nature present in the microstructure of the alloy. Duplex Stainless Steel Seamless Pipe have good mechanical characteristics and can be used in an as welded condition. Considered to be superior in comparison to austenitic alloys ASTM A312 TP304 or ASTM A312 TP316, the Seamless Duplex Pipe offers much better resistance to corrosion.

Duplex Pipe in custom length and sizes

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. As one of the foremost distributors and A790 Duplex Pipe manufacturer, we supply good quality products to our buyers. You can find the Duplex Pipe Price List here.
