Product Overview
A Slip On Flange (SO Flange) is designed to fit over the outside diameter of a pipe before being fillet welded on both the inside and outside. Its simple design allows for easy pipe alignment and installation, making it a preferred choice for low to medium-pressure applications where ease of fabrication and cost savings are important.
At Moksh Tubes & Fittings LLP, we manufacture precision-engineered Slip On Flanges using high-quality raw materials and advanced machining technology. Available in a wide range of sizes, pressure classes, and material grades, our flanges provide reliable sealing performance and excellent corrosion resistance for demanding industrial environments.
