Product Description

Weld Neck Flange (WN Flange)‌

WN Flange is a type of pipe flange characterized by a long tapered neck that transitions into the pipe wall, ensuring uniform stress distribution. It is connected to pipes via butt welding, providing high structural integrity and resistance to mechanical stress. The design includes a raised face (RF) or other sealing surfaces (e.g., ring joint, RTJ) to accommodate gaskets for leak-proof connections.
