Piping Alignment

Date 10-05-2005 04:37

With all due to respect,in the Jetty Top Side Project.The piping on the pipe rack which are welded,are not aligned in this regard ,according to paragraph 335.1.1 of ASME B31.3 standard any distortion is prohibited.
Nearly the 60 No. butt weld joints welded have this problem ,we ordered contractor cut out these joints but contractor want to pull the piping lines with chain block which will cause stress in welds,this procedure is not allowed. If you have any other opinion please let us to now.

I have to ask!
How did so much work get done before this was noticed?
Do you use a non-conformance report process and pass this info on to upper management?
Sounds like you may need to require the use of alignment tools if that particular contractor continues work.
You may have to consider pulling that contract.
Just a thought!
