As a result of its low reactivity, gaseous nitrogen will displace oxygen and moisture from the internal environment of the test components while simultaneously assessing for any potential leaks. Some of them are essential, while others help us to improve this website and your user experience. rl1 %PDF-1.5 % H\ CZm/q dExw, ~?qxF{nzQiq7mX^?V+2Nn=&&O 0000115586 00000 n 0000001882 00000 n Lympsham Np%p `a!2D4! endstream endobj startxref First 24 hour test I loaded nitrogen to 375 (390 is working pressure on low side), it sat rock solid for 7 hours until evening, then lost pressure to 325 by the next day. *F8`iTF+gA5J&K*,:.n4UxfJVFM-jOB=tkU93;UP!O@'yY*.kYKp(y;)bzVBTY%>np5(p+slsBCHfakb 16250 Tomball Parkway Houston, TX 77086, USA, 992 Arcy Lane, Building 992, Pittsburg, CA 94565, USA, Nitrogen & Gas Solutions | GENERON 2002 - 2019. 0000006101 00000 n The NITROKIT is needed to pre-check automotive A/C systems for leaks due to loose mechanical connections, hose leaks, evaporators and condensers.

Gases heat up during compression. Although testing will continue till the standard pressure rating of the test vessel is achieved, the upper limit for the test will be determined by varying industrial regulations concerning leak testing. dy! endstream endobj 45 0 obj <> endobj 46 0 obj <> endobj 47 0 obj [/ICCBased 78 0 R] endobj 48 0 obj <> endobj 49 0 obj <> endobj 50 0 obj <> endobj 51 0 obj <> endobj 52 0 obj <>stream This temperature rise should be compensated for by a stabilisation period. This is the basic principle on how the air conditioner actually works. In a second article on pressure tests on gas pipelines in our blog, we will once again deal with pressure reduction and situations from everyday working life, such as the influence of the sun on the results of the pressure test and what needs to be taken into account.
