Stainless steel flange plate flat welding flange 316L butt welding 304 chemical department flange plate
Full name of flat welded steel pipe flange with neck: Slip-ON for short SO
Neck flat welding flanges, like plate flat welding flanges, are also flanges that extend steel pipes and fittings into the flanges and connect with equipment or pipelines through fillet welds.
Sealing surface form of flat welding flange with neck:
Convex surface (RF), concave surface (FM), convex surface (M), tenon surface (T), groove surface (G), full plane (FF).
Diameter range of flat welding flange with neck: DN10~DN600
Applicable scope: PN series PN2.5~PN40; The Class Class150 ~ Class1500 series
Flange material: carbon steel, Luomolybdenum steel, 304, 316, 304L, 316L, 321, 347, CF8C.
Manufacturing process: forging.
Advantages: flat welding flange with neck is also a flat welding flange, because there is a short neck, so as to improve the strength of the flange and improve the bearing strength of the flange. So it can be used on higher pressure pipelines.
Disadvantages: more expensive than plate flanges and easier to knock in transit due to their shape characteristics.
