A weld neck flange is a type of industrial flange designed to transfer stresses to the pipe to reduce high stress concentrations at the base of the flange. Compared with other types, weld neck flanges are known for their tapered hub and gentle transition from flange thickness to pipe wall thickness. They are deformation-resistant, and are normally used for high pressure, high or low temperature conditions.

As a premium Manufacturer & Exporter in China, MetalGoods offers a variety of industrial pipe flanges to satisfy your specific requirements, which include weld neck flange, slip on flange, threaded flange, socket weld flange, lap joint flange, blind flange, spectacle blank flange, orifice flange and so on. Our products are made in accordance with ISO 9001-2015, Pressure Equipment Directive 2014/68/EU (PED 2014/68/EU), AD2000 Merkblatt W0, and API standard.
