Request for analysis of the reasons behind the cracking of 304 heating plates!

Here’s what happened: the steam heating plate of a vacuum drying machine in our company burst during use. This heating plate was repaired once due to leakage; the repair method involved adding a stainless steel piece to the original mounting solder joints in order to prevent leaks. The steam input pressure fluctuates within 15% around 4 kilograms, while the internal vacuum pressure is approximately 1 kilogram. The sheet is made of 304 stainless steel with a thickness of 4 MM. The internal reinforcement bars are 304 solid square steel. That’s all the information available for now.
It might be due to a mismatch between the stiffness of the reinforcement and the casing.
:Lol, I’m a complete beginner with no foundation; I’m learning*. Thanks to the moderator for the encouragement
It must have been created by the factory’s management themselves. It was not designed by a design institute.
Check again why the internal pressure has increased.
Check why the internal pressure has increased.
The designed pressure for these heating plates is 8 kilograms. The maximum pressure in our company’s steam main is 7 kilograms; after passing through several pressure regulators, the pressure in the workshops is around 4 kilograms. In other words, even if the heating plates get blocked, the pressure will not exceed 6 kilograms. It was the repaired heating plate that exploded; I now suspect that secondary welding may have caused changes in the metal’s properties, leading to the issues I mentioned above!
:Is there anyone here who knows something about the properties of metals?
