Operating temperature for wound gaskets
Thread Content
The operating temperature for wound gaskets is determined by the metal and filler; where can this information be found?
HGT20610-2009, right?
I’ve seen HGT20610-2009, but it doesn’t seem to explain things clearly; it only mentions that the temperature of the filling material needs to be taken into account. Are alloys like 321 and 347 suitable for use at any temperature?

Having only the gasket material and temperature, without the corresponding medium and pressure, seems to make little sense.
HG/T20592~20635, specifically HG/T20610
1. The standard gasket to be selected specifies the operating temperature and pressure (gasket specifications such as Class150~Class2500 in HG/T20631). 2. When choosing the gasket material, the corrosiveness of the medium also needs to be taken into account
NB47020~47027-2012: Flanges, gaskets, and fasteners for pressure vessels; detailed information is provided on page 83 of NB47025-2012
Can’t the data sheet from the gasket supplier be used?
For gaskets used on equipment flanges, refer to NB/T47025-2017 and GB/T29463.2-2012; for those used on pipe flanges, refer to HG/T20610-2009 and HG/T20615-2009
