Good afternoon, guys: A query; I am testing a leak with nitrogen in a cold store. Isolate the motor compressor from the pipe. The compressor maintains pressure. I put a cargo bar by the high pipe. I activated the solenoid valve and started adding nitrogen. That was last Friday and I left it at 250lb. Today I have where I put the cargo bar, where the high pipe starts from the compressor, a pressure of 40lb. In the receiving tank a pressure of 150lb. My question is, will the pipe be blocked? Of course, I appreciate any suggestions.
