Do high-temperature asphalt tanks need breather valves?
Thread Content
Is a high-temperature asphalt tank with a capacity of 200 cubic meters and operating at 175°C required to have a vent valve?
In response, first of all, I have not done this before. Checking the properties of asphalt, its boiling point is less than 470°C and its flash point is 204.4°C; at 175°C, there is no safety issue even if it is kept at an open state, as the vapor pressure is low at that temperature. So I think it’s better not to include a breathing valve after all
