Relationship between British standard tubing, pipe fittings, and process pipeline grade tables
Thread Content
The process pipeline grade table specifies the grade, material, pressure rating, and other details for various types of process pipelines. In high-pressure systems, the common measurement wiring method used in China is a 3/4\" process interface with a reduced diameter of 1/2\", followed by 1/2\" pipes that are connected to the instrument (transmitter). Through an adapter, these pipes are converted into tubing valves, and then there are British-style tubing pipes and terminal connectors. In the process piping table, each type of pipe fitting used in that category of piping has its own pressure rating (such as CL3000, 6000, 9000, etc.). British standard tubing and pipe fittings also have their own pressure ratings (3000, 6000, 9000 psi). There is a question: how to determine whether, for a certain high-pressure pipeline rating, British standard tubing and fitting components (such as end fittings) rated at 6000 psi or 9000 psi should be used?
Logically, this should establish a correspondence between the design temperature and pressure of the gauge and the PSI pressure/temperature gauge of the Swagelok ferrule, but it would be very cumbersome to do this for each one.
Do the conversion, LZ – there is a certain corresponding relationship
