Threaded connection
Thread Content
May I ask whether pressure gauges used on high-temperature pipes, such as steam pipes, are connected via flanges? Isn’t threaded connection that good? I would appreciate some guidance from experts, thank you!
For pressure gauges installed on high-temperature steam pipes, threaded connections generally work fine. When the temperature exceeds 200°C, it’s advisable to use copper or aluminum gaskets for the pressure gauge seals.
It can be connected using threads; no problem； High-temperature threads are prone to leakage, but those that have been properly installed may not leak
