ASTM 16.5 Weld Neck Flanges

We are Manufacturer, Supplier and Exporter of ASME 16.5 Weld Neck Flanges / WNRF Flanges. Weld Neck flanges or welding-neck flanges can be differentiated from all other types of flange by their long tapered hub. These flanges are bored to match the inside diameter of the mating pipe so there will be no restriction of product flow. The weld neck is therefore favoured in critical applications. Weld Neck Flanges are available in following specifications:
