The air quantity in the pipeline would be zero, so that variable can be eliminated. Hence why I only bleed the pressure down to approximately 10 spi, rather than zero; I want to eliminate the possibility of introducing air into the system. But I've searched the web for hours and I agree, that...

I work in the oil and gas industry and frequently encounter an issue involving isolation valves that do not seal 100%, and that begs me to ask the following question... I often need to isolate particular sections of piping so that a segment can be opened/disassembled for maintenance. When I...

If the valve is working as it should, there would be zero leakage through it, no matter the pressure differential acting upon the valve. Certain valves in the system seal 100%, others that are older, do not. When they don't seal 100%, it would be really nice to know how many litres/minute will...

Hello, my first post here. I encounter a situation frequently at work that I'd like help with so here it is... When I isolate a particular section of pipe (by closing valves), I then bleed off the pressure in the isolated section (volume of isolated pipe varies from 3 cubic meters up to about...
