Is the thread connected to the external threaded safety valve a straight thread or a tapered thread?
This depends on customer requirements or the default settings of various suppliers; generally, tapered threads are used for pipe threads, while round threads (G) can be used when high sealing requirements are not necessary
You need to check the thread type of the valve’s fitting in order to match it, unless you try to tighten it by force.
It is formulated in the form of external threads on the safety valve.
Everything is available, but it ultimately depends on what the customer requires; the configuration is done according to the customer’s needs
For safety valves, the national standard in China is RC, while the standard for safety valves in the US is NPT threads
GBT 12716-2011 60° sealed pipe threads
Tapered threads provide better sealing performance.
Column threads are sufficient for low-pressure conditions, while tapered threads are used for medium and high pressures
