Installation method of sonic nozzles
Thread Content
@boyirensheng @ckwcba @waaabc @Fish_in_the_desert @Sammy_Wang Hello everyone, I recently encountered a sonic nozzle that, based on its P&ID diagram, appears to be a globe valve similar to a safety valve – except that there is no diameter change before or after the valve. Does this nozzle also need to be installed with a standpipe, just like a safety valve? It would be great to have a view, thank you.
That account isn’t used very often, due to a bunch of subsequent problems caused by slow internet speeds. . . I’ve never seen this type of nozzle; there are materials from which images can be obtained.
I looked up information later and found that it is a corner valve, used for pressure reduction. It’s useful for natural gas production trees. I don’t have any pictures either, thanks
Is it a choke valve?
I’ve seen the shape and the description, so it should be that. The CHOKE VALVE, also known as a throttle valve of API6A type, is designed in accordance with the requirements of SY/T5127-2002, API Spec 6A, and API Spec 16C. Based on their structure, they can be divided into adjustable throttle valves and fixed throttle valves; the body of a fixed throttle valve can be interchanged with that of an adjustable one. Based on their operating principle, they are divided into manual throttle valves and hydraulic throttle valves. The valve cover and valve body are sealed by metal-to-metal contact. The fixed-throttle nozzle, the adjustable-throttle stem, the valve core, and the valve seat are all made of cemented carbide, offering advantages such as wear resistance, erosion resistance, and reliable performance. Based on function, they can be divided into needle-type adjustable flow valves and cylinder-type adjustable flow valves. Pin-type adjustable flow valves are primarily used in oil (gas) wellhead systems for regulating the flow rate of oil (gas) ； Cylindrical adjustable flow valves are primarily used in throttle well control manifolds to regulate the fluid pressure in the well. API6A adjustable throttle valve Note: a) Defined according to NACE standard MR0175 b) Complies with NACE standard MR0175
