Heat treatment issues in high-voltage equipment
Thread Content
Regulation 73: 1. High-pressure vessels, medium-pressure reaction vessels. Horizontal storage tanks for storing mixed liquefied petroleum gas in a pressurized state… should undergo overall heat treatment inside the furnace. …… The meaning of this sentence is that these containers must undergo heat treatment; should this heat treatment be carried out in a single furnace, or are only those high-pressure containers that require heat treatment supposed to be treated in a single furnace? GB150 does not mention any requirements regarding heat treatment for these devices; it primarily stipulates that heat treatment is necessary for containers whose materials and wall thicknesses meet certain criteria. For my current high-pressure separation vessel, which handles flammable and explosive media, is it necessary to carry out heat treatment on the entire vessel?
This was just discussed yesterday or the day before. You can look it up.
I think overall heat treatment should be carried out.
High-pressure vessels must be heat-treated, and it must be done through full furnace heat treatment.
Not all high-pressure vessels require full-scale heat treatment; for example, devices with multiple layers of insulation. According to the relevant regulations, only those high-pressure vessels that require heat treatment must undergo full-scale heating treatment in a furnace
Misunderstanding: L, agree with what was said on floor 5.
High-pressure vessels, medium-pressure reaction vessels and storage vessels, horizontal storage tanks for mixed liquefied petroleum gas... shall undergo overall heat treatment in a furnace. The understood meaning is: inside the furnace, and it is a full heat treatment. Corresponding to this is overall heat treatment outside the furnace. High-pressure separation vessels are classified as high-pressure vessels, so of course they should undergo overall heat treatment inside the furnace.
