Hi everyone. Needed some help understanding gas regulator leaks.
I was working with some nitrogen cylinders 1.5 m³(Don't know if it's important but both the cylinders are marked TP- 250 bar, FP-150 bar).
My old tank was giving a leak from the valve where the key is operated, so I got the new cylinder and now the regulator has begun leaking which was fine with the old tank. I have listed those instances below.
1. Regulator leaking with new cylinder - It is giving a leak from the structure into which the pressure gauge attaches itself to when I used it with my new cylinder.
2. Old cylinder leaking - I had to get this new cylinder because the last one had been leaking at the valve where the key is operated to close the valve on and off. It kept leaking even after tightening the gland nut.
Funnily enough the regulator had no leaks with this tank.
It is a single stage argon regulator with flowmeter from Esab. Max inlet pressure of 200 bar
Any help will be appreciated, I am racking my brains as to how one thing or the other. keeps malfunctioning.
Thanks
