Product Description

Petromet Flange Inc. is a biggest producer, supplier and Exporter of Welding neck Flange, WN solid Flange, welding-neck Flanges, ASME sixteen.5 Weld Neck Flanges / WNRF Flanges in cast metallic, stainless-steel, AS,CS and many others. Weld Neck Flange is flanges that designed to be joined to a piping gadget by using butt welding. This form of flange include plenty of specification,Weld neck Flange is highly-priced due to its long neck and cost of humans for contact WN flange with pipeline or fitting, however is preferred for excessive stress packages. The necks, or hubs, transmits stresses to the pipeline. The gradual transition of thickness from the base of the hub to the wall thickness on the butt weld provides important reinforcement of the Weld Neck flange. The bore of Weld-Neck flange matches bore of the pipeline, decreasing turbulence and erosion. Weld Neck Flanges are available in following specifications:
