Evaluation of Residual Stresses in High-Pressure Valve Seat Surfacing

  • Published:
Chemical and Petroleum Engineering Aims and scope

A high-pressure shut-off assembly fitting is a highly-loaded element. Application of flux-cored welding wire for strengthened the valve seat is considered. A valve heat treatment regime is recommended for ordering the microstructure and reducing stresses in the surfacing zone. Correlation of residual stresses with material microstructure is demonstrated.
