What kind of heat treatment is required?
Therefore, assembly, welding, non-destructive testing, and heat treatment are extremely important. Failure is not allowed
It should follow a welding sequence and method similar to those used for spherical tanks, along with overall heat treatment.
Guess whether this end cap was welded manually or automatically? ? ?
External soft insulation material, internal fuel atomization for combustion.
With such flat equipment, using the fuel method may result in poor gas distribution

If it is done by manual welding, the payment is calculated on a per-centimeter basis. Assembly involves welding clamps on the plate surface, and then connecting the components together using wedges. After welding, it is heated from the inside using liquefied gas or similar, and insulated from the outside with glass wool. A giant – I’ve heard that nuclear reactors have such things,,,
