Dear Petar K,
Thanks for sharing your knowledge, i was confused before but now i am clear for the leak test. Like you said we have did the high pressure leak test in the last project with 90% of PSV set pressure. So now i am clear about that one.
For the pressure drop during leak test, i have...
Dear All,
If anyone know the definition about process and non-process.
Electricity will fall under process or non-process.
As air, water, steam and nitrogen falls under nitrogen so same as electricity also falls under utility ?
API RP 1110 (Section 4.1.7.4 Leak Test)
refer this standard for leak testing of pipelines. it gives the test pressure also duration. but this is for pipeline but for leak testing of piping system in the refinery including equipment's during commissioning. i need to know the standard number.
so...
Dear GD2, I have experience in site conducted the pre commissioning and commissioning works based upon the procedures created by the engineers. but now i am responsible for creating that procedures. so for conducting safe work and following the previously employed procedures here is not a...
Hello dears, thanks for the info shared. But i didn't find the solution. Like i said i am working in a sour gas plant which need to be commissioned. so after completion of hydro/ pneumatic test by construction team. we will start air blowing when blowing and reinstatement of the removed...
Dear collegues,
Let me clear it one time, so you will understand it clearly.
I am not asking about the leak test for pipeline or during construction phase such as hydrotest or pneumatic test.
The test will be conducted after completion of hydro/ pneumatic test by construction team and air...
Yes sir i am writing the procedure for leak test and inerting. There is no any project documents available. That's why i asked about if any API or ASME standard which covers this one will be helpful. Because when i asked my previous manager he told that he took it from API standard only.
Like...
We are using ASME code for designing in old project also same. But i don't know which API standard they took 90% of design pressure as test pressure.
Purging will be carried out after the completion of leak test. Right ? So i need for the acceptance criteria for purging such as oxygen content...
Hello Dear Professionals,
I got promotion as engineer of pre commissioning and commissioning. But after getting into this position only i got lot of doubts that i missed to ask my manager during the preparation of documents in the last project.
1. For the leak test during pre commissioning...

ok dears thank you. because i couldn't find the solution and after seeing that table maybe have some calculations that i may not know. now i understand clearly thanks for your quick responses.
we have a tensioning tool and with that we received a sheet you can see in the attachment. it's showing bar and torque value corresponds to the bar value. but this value is different from model to model. if the vendor can provide such document. then maybe the have some calculation. that's what i...
Hello friends, i am facing a little problem for the conversion of pressure value to N.m for performing bolt torquing. from the supplier we received the torque value is as 23Mpa/ 230bar but the bolt we were going to do torque is 3/4". As per our company standard only after 1 1/4" bolts only...
