Is it okay to use asbestos gaskets in a heat transfer oil system? Can they be used?
Thread Content
Could an expert help answer this? Can asbestos gaskets be used in heat transfer oil systems below 300°C and those below 150°C?
Asbestos gaskets are no longer used; metal wound gaskets should be used instead
It was used before. Now metal wound gaskets.
It is recommended that the poster use graphite metal winding
Asbestos gaskets are not recommended; double-ring metal wound gaskets are advised
Personally, I recommend that the poster provide specific operating conditions: temperature, pressure, flange design type, operating conditions (such as presence of temperature variations or pressure variations, etc.). Regarding the medium and temperature of the heat transfer oil, I believe that, aside from being environmentally unfriendly, asbestos should not pose much of a problem. But XB450 must be chosen. Thank you.
Bro, this isn’t an environmental issue; it’s a toxic one. Asbestos gaskets must be phased out – they absolutely cannot be used anymore. If foreigners hear that there are asbestos pads in the factory, they definitely won’t go in to work there. Replace it quickly.
No, it is recommended to use metal wound gaskets.
Is the toxicity that high? Is there any information?
