The pipe fitting is used at a pressure of 18 MPa; the outer diameter of the welded joint is 31, with a wall thickness of 4. Is it sufficient?

The pipe fitting is used at a pressure of 18 MPa; the outer diameter of the welded joint is 31 and the wall thickness is 4 – is that sufficient?
There’s definitely no problem with withstanding pressure
The pressure resistance is fine, but the wall thickness seems too thin to me; for 18 MPa, a stainless steel pipe with a thickness of 6–8 layers should be required. For CNG, we use pipes with a thickness of 10 layers to handle pressures of 25 MPa.
What does \"bearing pressure\" mean? The wall thickness was accidentally made too thin. Will there be a boom?
Theoretically, it should be able to withstand these pressures; you should conduct pressure tests. The main issue is that corrosion during operation will make the pipes thinner and increase the risk of accidents
Leaking. Will it also become thinner over time?
It should be fine in terms of withstanding pressure, but being this thin, it will likely become thinner over time, which could be dangerous
Theoretically, there’s no problem; this additional margin for wall thickness should be 1-2
Theoretical calculations show that around 2 millimeters is sufficient. . .
What will happen if the wall thickness is insufficient and welding is carried out under high pressure?
