The flat welded flange with neck, like the flat welded flange of the plate type, also extends the steel pipe, pipe fittings, etc. into the flange and connects with the equipment or pipeline through the fillet weld. The sealing surface forms are: protruding surface (RF), concave surface (FM), convex surface (M), tenon surface (T), groove surface (G), full plane (FF), ring connection surface (RJ).
Butt welding flange with neck refers to a kind of flange with a tapered neck and butt welding with the cylinder or pipeline. It belongs to the integral flange. Due to the excessive structure of the cone neck and the butt welding connection, the strength and rigidity of the flange are strengthened, the butt welding flange is not easy to deform, the sealing is good, and it is widely used.
Flat welded flange refers to a kind of flange connected with fillet weld seam with container or pipeline. The flat welded flange has a simple structure and saves materials, and is widely used in the connection of medium and low pressure vessels and pipelines.
Plate flat welding flange (chemical standard HG20592, national standard GB/T9119/mechanical JB/T81): convenient to take materials, simple to manufacture, low cost, widely used; However, the rigidity is poor, so it should not be used in chemical process piping systems and highly hazardous occasions where supply and demand, flammable, explosive and higher vacuum requirements are required. The sealing surface type has flat and protruding surfaces. Welding form: plate flat welding flange is to insert the pipe into the flange to weld.
