Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality ASTM B622 Seamless Pipe, which are almost never used above 300 Degree C. Although it has good high temperature oxidation resistance, our ASTM B622 Nickel-Cobalt Pipes suffers from embrittlement if held for even short times at temperatures more than 300 Degree C. If embrittled, these ASME SB 622 Nickel-Cobalt Tubes can only be rectified by a full solution annealing treatment. Our ASTM B622 Nickel-Cobalt Seamless Pipes finds applications due to both excellent corrosion resistance and high strength. Solution treatment (annealing) – heat of these ASME SB 622 Nickel-Cobalt Seamless Tubes is up to 1020 Degree C – 1100 Degree C and cool rapidly.

Our ASTM B622 Nickel-Cobalt Alloy Pipes cannot be hardened by thermal treatment, but does work harden. Welding methods together with gas – arc welding, metal – arc welding, gas – metal – arc welding and submerged – arc welding are recommended on these ASME SB 622 Nickel-Cobalt Alloy Tubes. Hot working on our ASTM B622 Nickel-Cobalt Alloy Seamless Pipes needs to be carried out by choosing proper temperatures.
Typical temperatures of these ASME SB 622 Nickel-Cobalt Alloy Seamless Tubes for hot working are between the ranges of 648 Degree C – 1176 Degree C (1200 Degree F – 2150 Degree F). The alpha precipitate phase of these ASTM B622 Tubes as well presents risk of embrittlement in the range of 660 Degree F and 1020 Degree F (350 Degree C / 550 Degree C).
Scope And Manufacturing
ASTM B622 specification covers seamless pipe and tube of nickel and nickel-cobalt alloys (UNS N10276, UNS N06022). Seamless Pipes and tubes shall be supplied in the solution annealed and descaled condition. When atmosphere control is used,descaling is not necessary.
When atmosphere control is used, descaling is not necessary. Mechanical properties of the material like tensile strength, yield strength, and elongation shall be measured. Tension, hydrostatic, and nondestructive electric tests shall be done on each pipe or tube. The mass or weight of each pipe shall be calculated and the chemical composition of each pipe shall be determined.
