ASMEB16.5A105SO with neck flat welding flange manufacturers

With neck flat welding flange sealing surface form with a neck flat welding flange are: raised face (RF), concave (FM), convex (M), tenon surface (T), the groove surface (G), the whole plane (FF ). With neck flat welding flange diameter range: DN10 ~ DN600 Scope: PN series PN2.5 ~ PN40; Class series Class150 ~ Class1500 flange material: carbon steel, Luo molybdenum steel, 304,316,304L, 316L, 321,347, CF8C. Manufacturing process: forging. Advantages: with neck flat welding flange welded flange belong, because there is a short-necked, thereby increasing the strength of the flange improves the bearing strength of the flange. It can be used in higher pressure pipelines. Disadvantages: higher than the plate flat welding flange terms of cost, because of its characteristic shape is easier to bump in transit.
