What is the acceptance for piping straightness/alignment? Is this accepted?
this spool not misalignment. found slight slope at vessel side.
This spool is branch connection to the header…Yes it is slight slanted (slope). Is there any acceptance criteria for this?
As my point of view, we may accept this joint or you may adjust the weldolet.
Most European standards apply ISO 2768-1 1989, there are 4 class - f, m, c, v. You may refer to there and which your project apply to.
