Steel Lap Joint Flanges

Steel Lap Joint Flanges are designed for piping systems that require frequent dismantling, inspection, and maintenance. Used together with a stub end, these flanges can rotate freely around the pipe, making bolt alignment quick and easy during installation. Their flexible design and durable steel construction make them an ideal choice for industries where easy assembly and long-term reliability are essential.

At Royal Steel India, we manufacture and supply premium-quality Steel Lap Joint Flanges in a wide range of sizes, pressure classes, materials, and international standards. Our flanges are precision-engineered to deliver excellent strength, corrosion resistance, and reliable performance in demanding industrial applications.

Steel Lap Joint Flange

Steel Lap Joint Flanges are backing flanges that are used with a welded stub end instead of being directly welded to the pipe. The flange rotates freely over the stub end, allowing easy alignment of bolt holes and simplifying installation. This design also makes maintenance, inspection, and replacement much easier without disturbing the entire piping system.

Steel Lap Joint Flanges are commonly used in industries where piping systems require regular servicing or where corrosion-resistant materials are used for the stub end.
