SA335 Grade P22 pipes, ASTM A335 Grade P22 Alloy Steel Seamless Pipes can be heat treated with full or isothermal annealing and with normalized and tempered methods at 675 degrees Celsius to add hardness. It is a chrome moly type of pipe with chromium and molybdenum in the composition. With this composition of 4-6% chromium and 0.45-0.65% molybdenum, they get minimum yield strength of 205MPa and the minimum tensile strength of 415MPa. These SA335 P22 Pipe suppliers have to pass the manufacturing tests such as the EN 10216-2, UNS K21590, GOST 550-75 and NBR 5603 in order to get certified.
ASTM A335 Grade P22 Alloy Steel Seamless Pipes
SA335 Grade P22 Pipes
The pipes could range from 3/8 inches to 30 inches in outer diameter and can have different wall thicknesses up to 250mm. The wall thicknesses and the diameter define the schedule or pressure containment of these pipes. There are schedules 20 through XXS in this particular product range. The ASTM A335 Grade P22, ASTM A335 P22 Pipes can be hot rolled or cold drawn to be seamless. They come with beveled and plain ends in addition to the coupling style. The Alloy Steel P22 Chrome moly pipes, A335 P22 Welded Pipes could also be coated as a finish with color painting, 3LPE coating or epoxy coating. These allow the ASTM A335 Gr P22 Pipes to have added corrosion resistance properties.
