Companion Flanges Manufacturer, Supplier & Exporter
Companion flanges, also known as threaded flanges, are designed for easy connection to threaded pipe systems without the need for welding. These flanges screw directly onto NPT threaded pipe and are bolted to a mating flange using a gasket to create a secure, leak-resistant seal.
They are widely used in low to moderate pressure applications such as water distribution, fire protection systems, compressed air lines, and general industrial piping. Companion flanges offer fast installation, easy removal, and simplified maintenance.
Manufactured in accordance with industry standards including ASME B16.5 and ASTM International material specifications, our companion flanges ensure dimensional accuracy, pressure integrity, and long service life.
