EN1092-1 PN6 - PN40 Stainless Steel Weld Neck Flanges ST37 C22.8 SS304 304L

Stainless Steel EN1092-1 TYPE 11 PN6 - PN40 Welding Neck Flange

Description:

EN flange is a flange system from England, which have flange type including TYPE1(Plate Flanges); TYPE2(Losses Plate Flanges); TYPE5(Blank Flanges); TYPE11(Weld-neck Flanges); TYPE12(Hubbed Slip-on Flanges For Welding); TYPE13(Hubbed Threaded Flanges)etc., pressure grade have PN2.5 PN6 PN10 PN16 PN25 PN40 PN63 PN100, Size from 1/2" NB TO 48"NB.

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.

Specifications:

Stainless steel EN1092-1 TYPE 11 welding neck flange is forged flanges. The flange can connecting pipes, valves, pumps and other equipment to form a pipework systems. It is the machinery, petroleum, chemical, water, electricity, shipbuilding sectors piping systems and devices most widely used pipe fittings.
