Helium Leak Test
Posted by: Ramakrishnan Muruganantham (PID_629), E-mail: rm@audcoindia.com, on June 12, 2000 at 11:44 :
A customer wants "High pressure helium test of valve body at 5725 psi (400 bar-approx). Test Duration: 10 minutes; No leakage permitted". The valves are required for hydrogen service.
We would like to know the following:
1. Is it required to do helium leak test at such a high pressure?
2. Is it technically correct to do leak test at above pressure (with respect to sensitivity)
3. Any advantages of doing such high pressure test?
4. Any alternate method for achieving the object of detecting any leak path?
5. Any international standard recommending correct procedure of helium leak test with pressurisatio method?
6. Is there any limitation on pressure with helium as test media.
