Pipe Fittings Flange,Steel Flange, forged stainless Steel Flange,Weld Neck Flange, Slip on flange , Plate flange , Blind Flange

Welded neck flange not easy to  distortion, good sealing, widely used, butt thinning transition weld joints ,horn shape, avoid shape change when welding in high temperature. applicable to high temperature pipeline, high pressure and low temperature pipeline, normally used to connect  pipes and valves which PN is greater than 2.5MPa; also used to transport expensive, flammable, explosive media pipeline.

Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications.
Key Features:
·This is the most common type of high pressure pipe flange.
·They are distinguished from other types of pipe flanges by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe.
·The long tapered hub provides an important reinforcement of the weld neck flange proper in terms of strength and resistance to dishing.
