ASTM A790 UNS S32950 one of the super duplex grades available in the market. The pipes are high temperature tolerant, resistant to pitting corrosion, crevice corrosion and stress corrosion cracking. The corrosion resistant features of the SA 790 UNS S32950 material make them applicable for highly corrosive environments like the marine and sea water applications. The strength of the Super Duplex UNS S32950 Pipe is used in applications like construction and structural engineering. The Super Duplex S32950 Seamless Pipe is also thermally conductive and withstand high temperatures and pressures. These mechanical properties are used in refineries, petrochemical industries, power plants and nuclear power stations as well. The pipes could be seamless or be welded. The ASTM A790 UNS S32950 Welded Pipe is stronger and can be used mostly in structural material that requires much strength.
There are different pressure classes and standards of the pipe materials. The SA 790 UNS S32950 Tube is such a standard used. The Duplex S32950 UNS Seamless Pipe has less absolute roughness and even wall thickness and diameter. This allows the pipe to be used in precision applications where the dimensions need to be accurate. There are different shapes of the pipes. The round and hollow shape is the common one but there are others such as the SA790 S32950 UNS Bush Hex Pipes. The duplex material has a dual nature. It contains the features of austenitic steel types and the ferritic steel types because of the metallurgic microstructure. This is what brings the name, duplex. The material therefore shows best strength characteristics from the ferritic phase and the corrosion resistance characteristics from the austenitic phase. The UNS S32950 Stainless Steel ERW Pipes can be used for welding purposes. While fitting the pipes together, the Super Duplex UNS S32950 Pipe Sleeve could be used to seal the connections.
