A Slip-On Flange (SO Flange) is a popular type of pipe flange designed to slide over the pipe before welding. It is welded on both the inside and outside, providing strong leak-free connections. Slip-On Flanges are easy to align, simple to install, and commonly used in low to medium pressure pipelines.

They are preferred in many industries because of their cost-effectiveness, low hub height, and simpler positioning compared to other flanges.
