Help needed: installation of pressure gauge on pressure vessel
Thread Content
Is it in compliance with the standards to have a backflow pipe installed on the pipeline leading from the pressure gauge of the tank pump in the workshop, in order to prevent the filter screen from getting clogged? Can’t it be installed? The people in my department say that my equipment doesn’t meet the standards and have ordered it to be corrected. . .
So, is it using the branches of the pressure gauge tube for backwashing? It’s best to revert to the original design. If rectification is needed, you can confidently submit a report requesting the equipment department to contact the manufacturer for a new design. It is reasonable to require rectification, as there may be a difference between the pressure in the backflow pipe and the actual pressure indicated inside the tank.
No, it was designed that way originally; the drawings didn’t provide such detailed specifications, and the equipment department said that this design had no basis and requested that it be changed. .
As long as there is no overpressure, it can be installed in this way. The regulations require that a pressure gauge be installed on the root valve, and the purge line also needs to have a root valve; it should be closed when purging is not in use
