A weld neck flange is a type of flange that can be welded to the termination of a pipe or fitting. It is defined by a long, tapered hub that neatly transitions to the pipe's diameter and a welded neck. This design transfers stress from the flange to the pipe, lowering the danger of leakage or failure under high pressure and temperature conditions.
Weld neck flanges are widely utilized in high-pressure, high-temperature applications, including the oil and gas sector, petrochemical plants, and power production facilities. They provide a robust, dependable connection between pipes or fittings and are ideal for applications where joint integrity is crucial.
