flanges FAGE ABES hreaded (Screwed) s made steel, are confined to special applications. heir chief merit is that they can be assembled without welding: this explains their use in extremely high pressure services, particularly at or near atmospheric temperature where alloy steel is essential for strength and where the necessary post weld heat treatment is impractical. Screwed flanges are unsuitable for conditions involving temperature or bending stresses any magnitude, particularly under cyclic conditions where leakage through the threads may occur in relatively few cycles heating or stress: seal welding is sometimes employed to overcome this, but cannot be considered as entirely satisfactory. Slip On Welding neck s are distinguished from other types by their long tapered hub and gentle transition thickness in the region the butt weld joining them to the pipe. he long tapered hub provides an important reinforcement the flange proper from the standpoint strength and resistance to dishing. he smooth transition from flange thickness to pipe wall thickness effected by the taper is extremely beneficial under conditions repeated bending, caused by line expansion or other variable forces, and produces an endurance strength welding neck flanged assemblies equivalent to that a butt welded pipe. hus this type flange is preferred for every severe service condition, resulting from high pressure or sub zero/ elevated temperatures, and whether loading conditions are substantially constant or fluctuates between wide limits: welding neck flanges are particularly recoended for handling high explosive, flaable or costly liquids, where loss tightness or local failure may be accompanied by disastrous consequences. Blind hreaded Slip on s continue to be preferred to welding neck flanges by many users due to their initially lower cost, the reduced accuracy required in cutting pipe to length and the somewhat greater ease assembly alignment; however their final installed cost is probably not much, if any, less than that welding neck flanges. heir calculated strength under internal pressure is the order two thirds that welding neck flanges, while their life under fatigue is about one third. For these reasons slip on flanges are limited to sizes 1/2" to 2 1/2" in the 1500lb standard, are not shown in the 2500lb standard and the ASE Boiler Construction Code limits their use to the 4" size. Welding eck Blind s are used to blank f the ends piping, valves and pressure vessel openings. From the standpoint internal pressure and bolt loadings, blind flanges, particularly in the larger sizes, are the most highly stressed all American Standard flange types; however, since the maximum stresses in a blind flange are bending stresses at the centre, they can safely be permitted to be higher than other types flanges. Where temperature, or repeated severe water haer, is a service factor, consideration should be given to closures made welding neck flanges and caps. Bore (Rating) able Out. o.
