• The effective sealing area of the mating flange must be free from gouges or deformities of any type to ensure proper gasket sealing.• Working pressure and/or end load are total allowable.• One time field test pressure may be increased to 1.5 times the figures listed above.• Required flange bolts to be supplied by installer.• Using AF-4 Flanges as anchor points for tie rods across joints that are not restrained is prohibited.• When using wafer or lug-type valves to join fittings, verify disc dimensions to make sure adequate clearance is available.• The hinge points / latch bolt locations must be staggered, and a flange washer (3"-12") or transition ring (14"-24") must be used when mating two AF-4 Flanges.h• AF-4 Flanges require a smooth flat sealing surface. Some applications do not provide an adequate sealing surface. In these cases, a metal flange washer must be inserted between the AF-4 flange and the component.
