A weld neck flange features a long tapered hub that smoothly connects to the pipe or fitting via butt welding, where the pipe end is inserted into the flange and welded around its circumference. This ensures a robust, leak-proof joint, while the hub reinforces the flange, reducing susceptibility to distortion or damage. Commonly used in high-strength applications such as petrochemical, oil and gas, and power generation industries, weld neck flanges are available in materials like carbon, stainless, and alloy steel to meet diverse operational needs.
