These pipe flanges are connected by welding the pipe to the neck of the flange. Instead, the stress is transferred from the flange to the pipe. It also reduces stress concentration from the bottom of the hub. Welded neck flanges are commonly used in applications that require high pressure. The inner diameter of the flange is designed to match the inner diameter of the pipe. Welded neck pipe flanges with hubs have published specifications ranging from 1/2 inch to 96 inches. Our company provides all material grades, specifications and sizes of these.
