How to control temperature during the hydrostatic testing of pressure vessels in winter?
Thread Content
For hydrostatic testing of pressure vessels made of materials such as Q245, the temperature must be no lower than 15 degrees Celsius. In this season, it’s especially difficult to reach such temperatures in the north. So how is this temperature achieved in manufacturing plants nowadays? I see that some manufacturing plants use gas for ignition in their baking equipment – is that okay? Welcome everyone; feel free to participate actively in the discussion.
Hot water is available under certain conditions. The hot water we’re using today to test the floating roof tank!
It is likely necessary to ensure good insulation; due to its large volume, water fills up slowly but heat dissipates quickly
The requirements for hydrostatic testing of carbon steel materials generally state that a temperature of not lower than 5 degrees Celsius is sufficient
