Pressure transmitter pressure lead
Thread Content
As the title suggests, I would like to ask whether the pressure tapping tubes for pressure transmitters can be fabricated on-site? It is initially considered to use Monel 400 alloy for the pressure tap pipes, with flange connections; the material of the pipes to be measured is fiberglass-reinforced plastic.
For on-site piping, how can the quality of flange welding at the site be controlled? Is a test needed?
Is it a pressure transducer with a single-flange diaphragm? Generally, these come with capillaries
Generally, piping installation is carried out on-site...
Uh, okay. Thank you. . I’m worried about on-site welding; the client wants inspections and approvals, which would be very troublesome
It’s either a differential pressure switch or a pressure transmitter; the differential pressure version is equipped with a 5-valve assembly
Isn’t the differential pressure usually handled by a three-valve assembly?
Yes, isn’t the differential pressure usually handled by a three-valve assembly? 1 balance valve, 2 stop valves
