ASTM A790 Duplex Pipe supplier

Manufacturer, Supplier and Exporter of ASTM A790 Tubing, ASTM A790 Tube, ASTM A790 Pipe, ASTM SA790 seamless pipe

ASTM A790 Pipe is made from austenitic- ferritic stainless steel and this is the type of steel that is used to make seamless pipes, as well as welded pipe. Pipes made by us, Steel Tubes India, from this material, are available in shapes such as oval, square and rectangular. A good feature about these pipes made from ASTM A790 material, is that they can easily be shaped or sheared by pressing, drawing, bending and various other common processes.

With ASTM A790 UNS S32760, after cold working is done, heat treatment is not normally called for. But, if it is necessary that hot working has to be done with this material, then this process should be done in a temperature range of 1800 – 2100 °F. It is very important to note that workability is reduced at higher temperatures. Also, if heated above 2100 °F, for a longer time period, heavy scaling could occur. After hot working is done, the tubes must be annealed at a minimum temperature of 2100 °F and then cooling must be carried out rapidly, preferably by water quenching. This process of annealing is very vital, as it serves to eliminate inter metallic-phases that could precipitate, in the process of hot working and in this way, these tubes provide maximum resistance to corrosion.

Pipes made from ASTM A790 UNS S32205 material, display superb resistance to corrosion fatigue and stress corrosion. These pipes also have a high mechanical strength. Covered in this ASTM A790 specification are welded pipes and seamless pipes which are ferritic-austenitic. Pipes of this kind are in big demand for use in hydrometallurgy, heat exchangers, seawater handling, gas processing, chemical industry process equipment, power generation, chemical equipment, specialty chemicals, condensers, pharmaceuticals, off-shore oil drilling companies, etc.
