No scoring will be given after two days, except during holidays. ...........................................................................a. Generally speaking, the heat treatment of pressure vessels is classified into four types according to its purpose: ( ), ( ), ( ), and ( ). Comment: Basic knowledge on pressure vessel manufacturing. Errors in this question often arise from confusing \"heat treatment to restore mechanical properties\" with \"heat treatment to improve mechanical properties\"; in fact, these two types of heat treatment serve different purposes. ........................................................................... Answer: Generally speaking, the heat treatment of pressure vessels is classified into four types based on its purpose: post-welding heat treatment, heat treatment to restore mechanical properties, heat treatment to improve mechanical properties, and hydrogen removal treatment.
Generally, the heat treatment of pressure vessels is classified into four types based on its purpose: post-welding heat treatment, heat treatment to restore mechanical properties, heat treatment to improve mechanical properties, and degassing treatment.
Improve mechanical properties, eliminate stress, refine the structure, and restore mechanical properties
Post-weld heat treatment: Heat treatment to restore mechanical properties; Heat treatment to improve mechanical properties; Heat treatment to remove hydrogen
Post-weld heat treatment, heat treatment to restore mechanical properties, heat treatment to improve mechanical properties, and dehydrogenation treatment
Heat treatment for the recovery properties of formed compressed components; Post-welding heat treatment; Heat treatment to improve the mechanical properties of materials; Other heat treatments
Generally, the heat treatment of pressure vessels is classified into four types based on its purpose: post-welding heat treatment, heat treatment to restore mechanical properties, heat treatment to improve mechanical properties, and degassing treatment.
