Water pressure and temperature of pressurized components in boilers
Thread Content
What is the water temperature when testing the pressure-bearing components of a boiler with water pressure? Such as 20G, 12G1MoV, and so on
Each type of steel is different; it is determined by the steel’s brittle transition temperature
GB150 stipulates that when conducting hydraulic tests on steel containers such as carbon steel, the liquid temperature must not be lower than 5 ℃； For other low-alloy steel vessels, the liquid temperature during hydrostatic testing must not be lower than 15 °C.
Boilers are generally made of carbon steel; in practice, 5 degrees is sufficient
According to the relevant regulations for steaming, the temperature should be within the range of 20 degrees to 70 degrees, and it must be above the steel’s brittle transition temperature. I would like to know what the specific water pressure temperature for steel is
