304 316L SS201 Stainless Steel Flanges Neck flat welding flange
Description
Neck flat welding flange is a flange that extends the steel pipe and pipe fittings into the flange and connects with the equipment or pipeline through fillet weld. The flange also belongs to flat welding flange, because it has a short neck, which improves the strength of the flange and improves the bearing strength of the flange. Therefore, it can be used for higher pressure pipelines.

Characteristic
Neck flat welding flange, the welding seam between the pipe and the flange is fillet weld, and the material is machined from ordinary steel plate with qualified thickness, while the neck butt welding flange is mostly machined from forged steel parts; Therefore, the flat welding flange with neck and butt welding flange with neck cannot be replaced casually.
Application
Neck flat welding flange is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and light industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and so on.
