Calculation of the intermittent thermal expansion amount between the valve body and seat of a high-temperature ball valve, seeking help
Thread Content
High-temperature ball valve: temperature of 450 degrees Celsius, outer diameter of the valve seat is 320, inner diameter is 250; material is 304, and the valve body is made of WCB. When the temperature rises to 425 degrees, what is the degree of thermal expansion of the valve seat? The valve body made of WCB also experiences expansion, but since its wall thickness is definitely greater than that of the valve seat, what should be the gap between them? How can this be calculated?
At a working temperature of 450 degrees, it’s strange if nothing goes wrong using WCB material
At such high temperatures, the material must be at least WC6.
