Product Introduction
SO100-2.0RF neck flat welding flange full name neck flat welding steel pipe flange English name: Slip on
The abbreviation SO with neck flat welding flange is the same as the plate flat welding flange, which also uses steel pipes
A flange that extends into the flange and is connected to the equipment or pipeline through a fillet weld.
The sealing surface forms of flanges with neck flat welding include: convex surface (RF), concave surface (FM), convex surface (M), tenon surface (T), groove surface (G), and full plane (FF).
Diameter range with neck flat welding flange: DN10~DN600 Applicable range: PN series PN2.5~PN40; Class series
Class150~Class1500 flange materials: carbon steel, molybdenum steel, 304, 316, 304L, 316L, 321, 347, CF8C.
Manufacturing process: Forging. Advantages: Neck welding flanges are also considered as flat welding flanges because they have a short neck, which increases the strength of the flange and changes its shape
The load-bearing capacity of the flange. So it can be used on pipelines with higher pressure. Disadvantages: Compared to flat welding flanges, the cost is higher due to its unique shape
It is more prone to collision during transportation.
