It is used for high temperature, high pressure operation or where there is wide fluctuation in pressure and temperature. These flanges are useful for handling costly, hazardous, flammable, explosive fluids, because failure or leakage of a flange joint can prove disastrous for the plant. The various dimensions to be specified for a welded neck flange are:
(a) Outside diameter of flange.
(B) Minimum flange thickness.
(c) Outside diameter of raised face.
(D) Diameter of hub at base.
(E) Diameter of hub at point of welding.
(F) Length through hub.
(G) Diameter of hole.
(H) Diameter of bolts.
(I) Bolt circle diameter.
(J) No. of holes.
