ZT45 Atlas Copco maintenance

Yesterday, one of air compressors running in our gas turbine plant have to be shut down because of system trouble alarm. That alarm comes from long time loading due to intercooler pressure low. As per previous encounters, the reason may be intercooler pipe. So we check this pipe between l.p compressor and intercooler ,and then we found air leaking out from this pipe when loading of compressor. This pipe causes trouble to us many times since original one was damaged . At that time we replace with a local made pipe fabricated by local workshop. The original genuine part is too expensive to buy for us .It's about 1200 usd for that small piece of pipe.

That's why we try it by local made but once a five months ,it damaged in crack. When we think of causing this problem , we assume intercooler dirtness.So today, we make it clean by thinner (chugoku) and reinstall pipe. Now, it's running well with IC pressure 0.232MPa. Please check my video .Thanks.
