Pressure Test Procedures

[dugal]

Hi Folks,
I was looking for 2 procedures and record forms I could use in the field with trades and Quality Control staff on how to set up and perform a hydrostatic code pressure test and a pnuematic code pressure test. There are the tests as described in the codes but I am looking for procedures that puts these out in layman terms for field staff.
Does anyone know of a website that contains such type of procedures and record forms ?

Hi Dugal,

May i know in which code you want the pressure test procedure? or you want a step by step instruction that the fieldmen can understand while performing pressure test

Hi askmani,
Thanks for the input. I was referring to the non-nuclear pressure vessel code used at our generating stations on steam generation and condensate lines, etc. I know there are specific codes but was looking for as you said a step by step field procedure.
Thanks dugal

Hi Dugal,
I don't Know if this will help or if will Comply with your code or your App.
Hydrostatic Test (New Boilers Or Boilers with Parts Repaird or Replaced)
If is on a Boiler:
1- Remove any safety valve and Blank off or use a test Clamp to gag them Close (On the Divece you are testing).

2- Make sure all the valve are close but the vent valve.

3- Fill the boiler with clean water no less then 70 deg. As the boiler is filling up check for leaks.

4- When filled close the vent valve and Gradually apply the test pressure 1.5 times of the MAWP.(Keep it under control)

That is just a basic Procedure. I'm not an expert but i hope thid help in some way.
