Abstract
Operational reliability of a pipeline valve depends on the durability of the weld sealing surfaces of the stop device, while the durability of the sealing surface is determined by the coating material properties. To enhance stop valve durability, a new composition for a flux-cored wire was developed, ensuring the generation of the surfacing metal with alloying system Cr-Ni-Mo-Mn-Si-Nb-Ti-B. Such wire provides overall hardening of the coating matrix with carboboride and intermetallic phases, providing an advanced operational reliability of stop valve nodes operating under friction conditions in aggressive environment.
