Selection of pipe flange type
Thread Content
Are the pipe flange types used for connecting butt valves proprietary or standard? If it is a standard component, what type of flange surface is generally used to achieve better sealing performance?
It should generally match the flange type at both ends of the valve
They are generally standard components. As for the type of sealing surface, it is usually convex or flat, unless special conditions such as high pressure apply, in which case a ribbed surface is used
Generally, it is necessary to determine what type of sealing surface the valve you are using has, and then choose a flange that is compatible with it. For example, if the valve’s sealing surface is concave, then the flange must be convex in order to work properly, okay!
