Is it necessary to heat a pressure vessel?the treatment you give the pressure vessel in the name of stress relief is enough; no further heat treatment is necessary as the same also serves the purpose as post-weld heat treatment. Generally, it is assumed that these are indicated in the drawing in the order in which the processes are to be carried out.See all results for this question

Residual Stress Relief in Post-Weld Heat Treatment | PVP pressure vessel fabrication Heat treatment
Jul 24, 2009 · Advanced Search. This paper focuses on analysis of weld residual stress relief process during furnace-based uniform post-weld heat treatment (PWHT). Two classes of pressure vessel steels: 2-1/4CrMo and carbon steel are considered in seam weld configurations. It is found that the dominant mechanism for residual stress relief is the creep relaxation that occurs much earlier during a PWHT Cited by: 5Publish Year: 2008Author: Pingsha Dong, Jeong K.
