RE: [MW:26330] RE: 26313] Hydro Test

Pressure test is a mandatory requirement of  pressure piping designed and fabricated according to B-31.1 code. Clause 137 & various other clauses  of this code explicitly specifies the requirements. The medium could be Hydro or Pneumatic.

 

Pneumatic test is  not advisable for safety and integrity of piping components. Hence Hydro test is the default choice.

 

Hope it clarifies your doubt.

 

Thanks.

Noted for your valuable point. But the contractor is asking to show the code requirements. 

 

B31.1 has followed for design and fabrication of the Piping.

What's the design and fabrication code for Piping??

 

Usually pressure piping  have to be hydro tested (by default) as like pressure vessel. No exceptions to rules?

 

A citation from the appropriate code or mentioning the appropriate code would be appreciated.

 

Thanks.
