Flange Type

There are many types of flange type, such as welding, welding, loose flanges. Its sealing surface has a convex, concave and convex face, tongue and groove, trapezoidal ducts. Flange type, sealing surface and sealing surface finish on the sealing performance impact.In the past,  Hydraulic pipe fittings the strength calculations, are aware of the same thickness weld neck flanges welded flange plate intensity ratio is good, and can be used for quantitative calculations, but theWhat kind of influence on the sealing flange, but no quantitative concept, GB150 also no flange stiffness formula.
