Regarding the issue of misalignment variables for the cylinder and head assembly
Thread Content
The head is spherical with a thickness of 8 mm, while the cylinder’s thickness is 13 mm. What should be the misalignment value during assembly, and where are the relevant standards to be found?
What about the edge angle E at the cylinder and head? Thanks
Calculate the error variable and edge angle E based on a thickness of 8 mm； During the manufacturing process, the edges of the thick plates should be trimmed to the required thickness according to standards.
When thinning out, should one pay attention to the calculated thickness of the cylinder?
It can be thinned or cladded, but the cylinder section should not be thinned. .
A container this thin with a spherical head is poorly designed. In the case of a ball seal, the alignment issue should be considered, and the misalignment amount should be treated as per Class A welds.
If it is a fatigue vessel, even though it is thin, can a spherical head also be used? !
