Solitaire Steel & Engineering LLP, located in Khetwadi, Mumbai, India, is a renowned supplier and exporter of lap joint flanges, serving clients worldwide. Our lap joint flanges are meticulously crafted to meet international standards, ensuring durability and adaptability for various piping systems. Unlike traditional flanges, our lap joint flanges are designed with a unique two-piece assembly, incorporating a stub end that is welded to the pipe and a loose backing flange. This design allows for enhanced flexibility in installation and alignment, as the flange can rotate freely around the stub end. Our commitment to quality and rigorous inspection processes set us apart, making our lap joint flanges a reliable choice across numerous industries globally.

Lap joint flanges are specifically designed to accommodate systems that require frequent disassembly or realignment. Featuring a flat face and a smooth surface, they are typically paired with stub ends that provide the sealing face and ensure a tight connection. These flanges are ideal for low-pressure applications, such as in chemical processing, water treatment, and marine environments. Due to their design, lap joint flanges allow for cost savings by using more affordable materials for the backing flange, while the stub end, in contact with the process fluid, matches the required pipe material. Our pricing varies depending on the material type, dimensions, and pressure class, providing competitive options that offer value compared to other flange types like slip-on flanges.
