Flange gaskets are used for the pressure gauge sealing
Thread Content
Gas storage tank: Medium – water, air. Design pressure: 4.4 MPa; design temperature: 90 degrees. What type of flange and gasket should be chosen? Does the pressure gauge connector require its sealing surface to be processed and sealed with a gasket?
There is red copper, tetrafluoroethylene, cowhide, etc., all of which can be used
1. The flanges should be necked butt-welded flanges. 2. Flexible graphite composite gaskets, wound gaskets, or metal-clad gaskets should be used as shims. 3. The pressure gauge connector itself features end-face sealing, and shims must be used for sealing it.
Waisted butt-weld flanges, metal wound gaskets, gasket sealing for pressure gauge connections
Gas storage tank: Medium – water, air. Design pressure: 4.4 MPa; design temperature: 90 degrees. What type of flange and gasket should be chosen? Does the pressure gauge connector require its sealing surface to be processed and sealed with a gasket? HG20595-97WN-FM flanges are to be used; metal wound gaskets with an inner ring are to be employed as gaskets, and copper gaskets are to be used for the pressure gauge gaskets
The conditions in question are not very stringent: the temperature is low, the gas is air, and it’s sufficient for the equipment flanges to have a male-female design, without the need for precise machining!
It is rare to see storage tanks for water or air media under such high pressure and temperature. The flange can be a necked butt-welded raised-face flange in accordance with the HG series standards ； Gaskets should preferably be toothed gaskets or wound gaskets, made of stainless steel with PTFE ； Tapered pipe threads should be used for the connection of pressure gauges.

Use convex flanges, wrap gaskets around the inner ring, and seal the pressure gauge with copper gaskets
Both copper and PTFE gaskets can be used
