Air Handling Units II_18 8. %PDF-1.4 %���� If one is intending to helium leak test a part; it is important to note that the tooling and pipework used to create the test volume and helium gas supply must be leak tight to a higher degree than the leak test threshold. �>����@�D�����h�cE���p����!B�4���������. When testing using helium it is possible to flood the mass spectrometer with helium if there is a large leak. • Turn the T handle (6) all of the way out (counter clockwise, looking from the bottom). Then repeat the “first stand-ing test” to determine if there is a de-crease in leak rate after the stabiliza-tion of the vacuum. 4. NITROGEN/HELIUM LEAK TEST Section 1.0 Introduction. 6. A combined nitrogen purge and helium leak-detection system has been developed to safely pressure test and commission oil and gas process equipment. 0000001324 00000 n %PDF-1.4 %���� The test pressure shall be 110% of design pressure. Videos you watch may be added to the TV's watch history and influence TV recommendations. A full procedure is available from the IOR (SES Good Practice Guide 24 – Pressurising installed systems with nitrogen to find leaks). LEAK TEST PROCEDURE All piping shall be pressure tested after the construction and before being place in operation to prove it has adequate strength for the propose and that it does not leak. Documents . 18 22 It is possible to test a part at high pressure and high vacuum at the same time. About Us. 5.
