Product Description
The full name of the welding neck flange is the neck flat welding steel pipe flange, which is a flange that extends steel pipes, pipe fittings, etc. into the flange and connects equipment or pipes through fillet welds.
The sealing surface forms of neck flat welding flange are:
Raised face (RF), concave face (FM), convex face (M), tenon face (T), grooved face (G), full face (FF).
Diameter range of neck flat welding flange: DN10~DN600.
Scope of application: PN series PN2.5~PN40; Class series Class150~Class1500
Flange material: carbon steel, Luomo steel, 304, 316, 304L, 316L, 321, 347, CF8C.
Advantages and disadvantages
Advantages: The neck slip on flange is also a slip on flange, because it has a short neck, which improves the strength of the flange and improves the bearing capacity of the flange. Therefore, it can be used on pipes with higher pressure.
Disadvantages: The cost is higher than plate flat welding flange, and it is easier to bump due to its shape.
