Manufacturing of Elbows
Manufacturing of Elbows
(OP)
Hi members
In one of our offshore projects while reviewing the material test certificates for 10 In Sch 40 90 deg elbows ( 9.27 mm) we have found from supporting documentation that the raw material for these elbows is 6in Sch 80 ( wall thk 11.1 mm)pipes. we have doubt on genuineness of the material since how the diameter can be increased from 6 in to 10 in while forming.Can someone dirct me to some info on the manufacturing methods of elbows from pipes.
Thanks in advance

The question was, how do start with 6" PIPE and end up with a 10" pipe elbow?

What is the pipe material?
What are the reference standards?
It is not common method for me. Did you ask the vendor to clarify?

We have been experiencing problems with validity of Test Reports from some parts of the world.
RE: Manufacturing of Elbows
I concur with you about the problems with validity of test reports. However, there are problems around the world...
It seems that the current market is for vendors and manufacturers. The purchasers have less power to ask for clarification in detail from vendors or manufacturers.
This is only my opinion...Good vendors and manufactures may be still available in this world...
Back to the case of sree60, the elbow manufacture should be the one who reply to his specific question...
Normally, I would not accept the material which is in doubt for the quality control record...

This happens when we give up, do not accept crap, and make them be responsible for the things they sell to the client... REJECT everything you have from this vendor if you feel that one piece is not correct... this is your gut talking to you or you would not have posted your concerns
