M Metal Tubes India Pvt Ltd is a trusted manufacturer and exporter of high-quality Lap Joint Flanges, designed for flexible, corrosion-resistant, and easy-to-maintain piping systems. With over 40 years of industry expertise and adherence to ASME, EN, and JIS standards, we deliver lap joint flanges that ensure optimal bolt alignment and simplified pipe maintenance.

What Are Lap Joint Flanges?

Lap Joint Flanges consist of two components: a stub end that is welded to the pipe and a backing flange that remains loose. The backing flange slides over the stub end and is free to rotate, allowing for easy bolt hole alignment. This makes lap joint flanges an ideal solution for systems that require frequent disassembly or in applications where bolt misalignment is a concern.
