Introduction
In modern fire protection systems, hydrant flanges play a crucial role. They connect hydrant valves, pipelines, and fittings securely. A hydrant flange ensures a tight seal that prevents leakages during high water pressure emergencies. Choosing the right flange improves safety and operational efficiency.
At Fortis Forge, we specialize in manufacturing durable hydrant flanges for industrial and municipal applications. Our products comply with global standards and deliver reliable performance.
What is a Hydrant Flange?
A hydrant flange is a flat, circular metal plate with holes around its perimeter. It connects a hydrant system to a pipeline or valve. The bolts secure it tightly to ensure leak-free operation.
Hydrant flanges are generally made from galvanized iron, carbon steel, stainless steel, or ductile iron. Each material offers unique advantages based on environment, pressure, and cost.
Types of Hydrant Flanges
Hydrant flanges vary based on pressure ratings, material composition, and application. Below are the most common types:
1. Weld Neck Flange
This flange is welded directly to the pipe. It offers excellent strength under high pressure.
2. Slip-On Flange
Easy to install, this type slips over the pipe and is then welded in place.
3. Blind Flange
Used to close or block a pipeline, blind flanges ensure complete shut-off.
4. Threaded Flange
Threaded connections make installation simple, without welding.
5. Lap Joint Flange
Used with stub ends, lap joint flanges provide flexibility in alignment.
Importance of Hydrant Flanges in Fire Safety
Hydrant flanges are not just pipeline accessories. They are vital safety components in fire suppression systems.
They allow quick connection between hydrants and pipelines.
They withstand sudden surges of water pressure during emergencies.
They prevent leakage that can weaken fire-fighting efficiency.
They support reliable maintenance and inspection of systems.
Materials Used in Hydrant Flanges
Material choice impacts durability and performance.
Galvanized Iron (GI): Affordable and rust-resistant.
Carbon Steel: Strong and ideal for industrial pressure handling.
Stainless Steel: Corrosion-resistant and suitable for harsh environments.
Ductile Iron: Flexible and strong under high pressure.
