slip-on flange sealing surface forms are:
Tu (RF), concave (FM), convex (M) and groove (T), groove surface (G), plane (FF).
With a flat welding neck flange size range: DN10 to 24 ")
Scope of application: PN series PN2.5 ~ PN40; The Class Class150 ~ Class1500 series
Flange material: carbon steel, no molybdenum steel, 304, 316, 304 l, 316 l, 321, 347, CF8C.
Manufacturing process: forging.
Advantages: with flat welding neck flange also belong to the welding flanges, because a short neck, so as to improve the strength of the flange improved flange bearing. So can be used in higher pressure pipeline.
Faults: a plate flat welding flange in terms of cost is higher, due to the characteristics of its shape is easier to knock against during transit. ss304 flange
