I am working for a pipeline construction company.
I have been in the process and pipeline services since 1999.
I joined this company to start a hydrotest division.
We are being asked by our customer to conduct a pneumatic test of 7 miles of 20" pipeline.
Test pressure is somewhere in the neighborhood of 1300 psi.
I am very opposed to this but my company wants to push forward. The customer has given us the green light.
We are doing this test within the week.
I need hard facts to stop my company from doing this. I have been looking for info on the net but have not been able to find something concrete.Or facts so i feel better about this.
I did find
"437.4.3 Only allowed for piping systems operated at 20% or less of SMYS"
