Slip-On Flange (SO Flange)
A Slip-On Flange (SO Flange) is one of the most commonly used flanges in industrial piping systems due to its simple design, easy installation, and cost-effectiveness. It is designed to slide over the pipe before being welded on both the inside and outside, creating a secure and reliable connection. Slip-On Flanges are ideal for low to medium-pressure and moderate-temperature applications across a wide range of industries.
At Royal Steel India, we manufacture and supply premium-quality Slip-On Flanges in various sizes, pressure classes, materials, and international standards. Our flanges are precision-engineered to deliver excellent performance, durability, and long-lasting reliability in industrial piping systems.
A Slip-On Flange is a type of pipe flange that easily slips over the outside diameter of a pipe before being welded into position. Unlike Weld Neck Flanges, it does not have a long tapered hub, making installation faster and more economical. Double fillet welding on both sides provides a strong and leak-resistant joint suitable for many industrial applications.
Slip-On Flanges are widely preferred where ease of fabrication, lower installation costs, and reliable performance are important.
