Flat welding flange
- Detail
-
The Flat Welding Flange (also known as Slip-On Flange) is a revolutionary pipe connection component engineered to deliver secure, leak-proof, and cost-effective joining for industrial, commercial, and heavy-duty piping networks. Unlike complex butt-weld flanges, this flange features a simplified design that slides directly over the pipe end, then secures via double-sided welding—striking the perfect balance between structural strength and installation efficiency. Designed to adapt to diverse pipe materials and pressure requirements, it serves as a critical link in systems where reliable connectivity, easy maintenance, and compliance with global standards are non-negotiable.
