Weld Neck Flanges

Product Description

A welding neck flange is a type of flange that has a long tapered neck that is welded to the pipe. It's designed to transfer stress from the flange to the pipe, reducing stress concentrations at the base of the flange. This design provides excellent strength and structural integrity, making it suitable for high-pressure and high-temperature applications in various industries such as oil and gas, chemical, and petrochemical. Welding neck flanges are commonly used in industries such as oil and gas, petrochemical, chemical processing, power generation and others where high-pressure piping systems are employed.
