Hi! I understand that you are referring to ethylene pipeline systems. Perhaps you can tell me in which direction to move in solving the issue. The problem is that when ethylene is pumped through pipelines, ethylene contains oil after reciprocating compressors (IR HHM).
Dear Sir, hello, your article is very helpful to me, thank you very much for sharing. But I did not understand the use order and way of the code in the article, and readANSYSModeFile2.m seems to have an error when reading the binary.mode file, how can I contact you?
Hi Neil, Cheng here. Sorry for bothering. It’s now 2025, and I’m still working on the settings for a SD14E relay. Similar to your post, I haven’t been able to find a manual for this relay. Would you be open to sharing any information you have on it? I’d really appreciate any help.

You posted about corrosion on a progressive cavity pump suffering of severe corrosion. Would you mind telling me if you finally were able to determine the source of the corrosion? When I saw the pictures, I immediately thought about cavitation but you specifically discarded that possibility due to the lack of noise, what make sense.
Did you figure out what the problem was?
I have a pipeline with a DP of 900 psi that will be Hydrotested to 1125 psi
in this pipeline there are 6 ball valves to drain/ vent the pipeline. Those valves (rating # 600) and accordingly the max operating pressure for those valves are 1480 psi.
can I hydrotest the pipeline with valves in closed position, and without installing blind flanges because it is difficult to remove during the hydrotest?
