ASTM B622/ASME SB622 is the specification that covers seamless pipe and tube of nickel and nickel-cobalt alloys. Pipe and tube shall be supplied in the solution annealed and descaled condition. When atmosphere control is used, descaling is not necessary. ASTM B622 Seamless Pipes and Tubes are exclusively used in nuclear devices, petrochemical industries, boilers, shipbuilding, and gas industries.
ASTM B622/ASME SB622 Nickel Alloy Pipe/Tube is resistant to low temperature aggressive corrosive environments as well as harsh high-temperature environments.
ASTM B622/ASME SB622 Nickel Alloy Pipe/Tube has excellent weldability and is able to join very successfully with other alloys with different compositions.
