Product Description
The full name of the neck flat welding 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 with equipment or pipes through fillet welds. The types of sealing surfaces include raised face (RF), concave face (FM), convex face (M), tenon face (T), grooved face (G), and full face (FF). Diameter range: DN10~DN600Scope of application
PN series PN2.5~PN40; Class series Class150~Class1500 Flange material: carbon steel, 304, 316, 304L, 316L.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.Data Reference
