Description
Galvanized Ductile Iron Backup Flanges
Galvanized Ductile Iron Backup Flanges are designed to provide a secure bolted connection when used with compatible grooved-end piping systems and stub-end adapters. Manufactured from high-strength ductile iron and finished with a corrosion-resistant hot-dip galvanized coating, these flanges provide dependable mechanical strength and durability for commercial, industrial, and fire protection piping applications.
The galvanized finish helps protect the ductile iron body against rust and corrosion, making these backup flanges suitable for demanding indoor and outdoor installations. Precision-machined bolt holes and flange surfaces help maintain proper alignment when assembled with compatible flange components, gaskets, and hardware.
