Welding neck Carbon Steel Flange

Weld Neck Flanges are flanges that designed to be joined to a piping system by butt welding. the WN flange is relatively expensive because of its long neck, but is preferred for high stress applications. The neck, or hub, transmits stresses to the pipe, reducing stress concentrations at the base of the Welding-Neck flanges. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Weld Neck Flange . The bore of the Weld-Neck flange matches the bore of the pipe, reducing turbulence and erosion.

The industrial processes come into die forging,and machining,we can provide a wide range of WN flanges,following on standards like ASME B16.5 Flange, ASME B16.47 Flange, DIN 2573 Slip On Flange, DIN 2631 Welding Neck flange, JIS Flange 5K SOP Flange and JIS Flange 10K SOH Flange. WN flange is a type of flange that extends steel pipes, pipe fittings, etc into the flange and connects with equipment or pipelines through fillet welds. This flanges have short neck, which increases the strength of the flange and improves the bearing capacity of the flange. So it can be used on higher pressure pipelines.

ASME Flange include ASME B16.5 Flange, ASME B16.47-A Flange, ASME B16.47-B Flange, this standard system include slip on flange, blind flange, welded neck flange, Threaded Flange , lapped joint flange (loose flange), socket welded flange, B16.36 Orifice Flange, long weld neck flange and Special Flange , sizes from 1/2 inch to 60 inch, class 150, class 300, class 600, class 900, class 1500, class 2500.
