Astm B626. Standard specifications for welded pipes from nickel and nickel-cobalt alloy.
Are you interested in the ASTM B626 standard concerning the production of electric-welded pipes from nickel and nickel-cobalt alloys from the supplier AvecGlob? Here you will find interesting information on this topic.
General information
This specification covers welded pipes of nickel-cobalt alloys with the numbers NS N10001, N10242, N10665, N10675, N10629, N10624, N10675, N06455, N06455, N06755, N06975, N06975, N06985, N06002, N06022, N06030, N06035, N06058, N06059, N06200, N06210, N08031, R30556, N06230, N06686 and R20033.
These alloys are designed for heat exchangers and condenser pipes, as well as pipes used in corrosive environments at high temperatures (heat resistant). Pipes should be made of sheet metal, then subjected to longitudinal bending (profiling) and subsequent automatic welding without the addition of fluxes. Further, the pipes must undergo heat treatment — annealing.
Materials meeting the requirements of ASTM B626 must meet the required mechanical parameters (tensile strength, yield strength and elongation), chemical composition, and also withstand flattening, flange bending, hydrostatic, electromagnetic and pneumatic tests.
Application area
This specification covers welded tubes of nickel-cobalt alloys supplied by UNS N10001, UNS N10242, UNS N10665, UNS N12160, UNS N10629, UNS N10624, UNS N10675, UNS N10276, UNS N06455, UNS N06007, UNS N06975, UNS N08320, UNS N06985, UNS N06002, UNS N06022, UNS N06030, UNS N06035, UNS N06044, UNS N06058, UNS N06059, UNS N06200, UNS N06617, UNS N10362, UNS N06210, UNS N08031, UNS N08034, UNS R30556, UNS N06230, UNS N06686 and UNS R20033). All of the above mentioned alloys are designed for use in corrosive environments and at high operating temperatures.
