Moreover, different levels of C in the standard flange thickness has been set to die, your height suddenly face protruding at the flange thickness meet the appropriate process to face, is usually a value of experience, what is the scope of a DN, but the protruding height is not high, are generally small according to DN, increased, increasing

Q: Introduction of flange: Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different.
