Issues with measuring the thickness of old gaskets
Thread Content
I have a question. There is a high-strength graphite gasket for the valve cover of a valve in my unit; after removing it, its thickness was less than 2 mm. What should be the thickness of a new gasket? Under normal operating conditions, there is no gap between the valve cover and the valve body.
You should ask the manufacturer about this, right? @The valve is clearly @Butterfly Valve Specialty Store @Xiamen Shuangte Valves
According to general standards, the thickness required is 1.5 mm for sizes below DN300, while the thickness of gaskets for sizes above DN300 is 3 mm; there are also thicker ones, with the thickness varying depending on the pressure.
3 millimeters. . . . . . . . . . . . . . . . . .
That nonsense is really scary… Can you be serious?
It should be 3MM. If the flange is damaged. The thickness should be increased accordingly.
