What type of tape should be used for heat transfer oil at 300 degrees?
Thread Content
I would appreciate it if experts could advise me on what type of tape to use for hot oil at 300 degrees
You can’t use raw tape anymore; you need metal wound gaskets or graphite gaskets
The temperature at the connector near the Supervisor is high; without using tape, it melts completely. For example, pressure gauges use flat-threaded + washer-type connections ； However, the joint temperature at the remote transmitter is low, so a tapered thread plus tape can be used. (Lessons learned from two projects)
It’s a heat-insulating jacketed valve, with a heat transfer oil at nearly 300 degrees as the medium in the jacket; currently, the drain plug on the jacket is leaking due to poor sealing. Is there any better way?
Hot oil sealing in the hot state generally uses flanges or flat threads. I heard that metal sealant (for high temperatures) has been used; I’m not sure about its effectiveness, so you might want to check that out.
Temperature. Pressure and medium requirements must be met!
