Hi all, This is Usman !
I am nowadays working at the construction site of ammonia plant (for fertilizer production), we are at the pre-commissioning stage and we haven't decided on a reliable standard procedure for the Leak Test for the Instrument Impulse Tubes.
Can anyone kindly refer me to a standard procedure which we can use at our site for LEAK TESTING OF INSTRUMENT IMPULSE TUBING. Our subcontractor is CNCEC (Chinese National Chemical Engineering Company) and their presented procedure is not impressive and has a lot of language barriers in it.
Thanks in advance
