INVESTIGATION OF THE EXPLOITATION CHARACTERISTICS OF BELLOWS EXPANSION JOINTS MADE OF HEAT-RESISTANT NICKEL ALLOY
Keyword(s):
Investigations of the macro- and microstructure, mechanical and technological properties of a metal strip made of heat-resistant nickel alloy Cr20Ni43Mo9Mn6Nb-vi were carried out. In order to determine the optimal composition of the pickling solution, studies were carried out on the use of various mixtures for pickling the surface of the strip. On the basis of the studies carried out, technological recommendations were developed for the preparation of materials before welding of bellows expansion joints.
