Pressure vessel instruments.
Thread Content
Pressure vessels all have limits regarding pressure and temperature. Do all pressure vessels need to be equipped with instruments such as pressure gauges and thermometers? If there are no such instruments on-site, should remote transmission devices be installed instead? I’ve checked some air tanks; some of them lack certain gauge accessories. Are they up to standard?
Yes, there need to be remote transmission systems as well as pressure and temperature display devices installed on-site; the remote transmission is for use by the control room, while the on-site displays are meant for inspection by maintenance workers
I don’t see any requirement to install pressure gauges and thermometers; it may be sufficient to install them within the piping system to monitor the area as a whole； It depends on whether it is necessary to view and control these parameters. For example, there are no instrument ports on the bodies of heat exchangers and similar devices. But the storage tanks you mentioned generally still need to be installed, right?
An air tank – a pressure gauge is essential.
Whether pressure vessels should be equipped with safety accessories and instruments (pressure gauges, thermometers, level gauges, etc.) depends on the function of the vessel and the system control requirements; it is a requirement of the design, with no standard imposing such a requirement. However, since the pressure source is generated inside the vessel, a safety valve must be installed on it.
Pressure vessels generally have pressure gauge ports； If the container needs to be heated or cooled, a thermometer is required ； If it is a container at room temperature, the thermometer can be omitted.
