A weld neck flange, one of the most common types of flanges, features a long inching hub that can be welded with a pipe. This flange type is used, typically, in high-pressure and high/ low temperatures applications

Weld neck flanges are a type of flange that is designed to be welded onto the end of a pipe. They have a long tapered neck that is designed to be welded to the pipe, and a circular base that provides a seating surface for the mating flange.

Weld neck flanges are used in a variety of applications, including high-pressure and high-temperature systems, and are known for their strength and durability. They are often used in conjunction with a gasket and bolts to create a leak-tight seal between two flanges.

Weld neck flanges are available in a range of sizes and materials, including carbon steel, stainless steel, and alloy steel. They are typically manufactured by forging or casting, and may be finished with various surface treatments such as galvanizing or chrome plating to improve their corrosion resistance.

that want an unrestricted inflow of the fluid conveyed by the pipeline. The absence of pressure drops prevents negative things like turbulence and corrosion/ erosion of the raw material in the proximity of the flange joints. The tapered base allows a smooth distribution of the mechanical stress between the pipe and the weld neck flange and facilitates the prosecution of radiographic examinations to detect possible leakages and welding scars.

The dimension of the Industrial Flange (schedule & NPS) shall match the dimensions of the connecting pipes. Thus, when ordering Steel welding neck flanges, the Customers shall inform the suppliers about the nominal sizes and wall density of the connecting pipes. A Industrial welding neck flanges are connected to a pipe by a single full penetration V-shaped butt weld.
