Plate Weld Flange
A Plate Weld Flange (PL Flange) is a flat, circular disc with bolt holes, designed to connect pipes, valves, pumps, and other equipment in piping systems. Unlike welding neck flanges (WN), plate flanges are simpler in design and welded directly to the pipe by fillet welding at the backside. Key Features: ✔ Simple & Cost-Effective – Made from a flat plate, reducing material and machining costs. ✔ Easy Installation – Requires only fillet welding (no beveling needed). ✔ Wide Applications – U...
