Plate Flanges

For robust pipe connection and sealing across various industrial sectors, Plate Flanges from Fortis Forge are valued for their structural strength, straightforward installation, and adaptability in both low-pressure and non-critical applications. These flanges are flat, circular discs welded directly to the pipe end and bolted together with a matching flange to form a tight, reliable seal. Precision-engineered to align with ASTM A105, ASME B16.5, and DIN specifications, Fortis Forge Plate Flanges are manufactured using carbon steel or mild steel for dependable performance and durability.

Our Plate Flanges are crafted using advanced cutting and finishing techniques to ensure dimensional accuracy, surface flatness, and secure fitment. They are ideal for systems where space is limited or welding needs to be minimized. Widely used in fire protection lines, water treatment systems, shipbuilding, HVAC, and general industrial pipelines, these flanges offer a practical and economical option for easy bolted connections.

With options in multiple sizes, thicknesses, pressure ratings, and face types (RF/FF), Fortis Forge Plate Flanges provide cost-effective and durable pipeline solutions. Designed for easy handling and reduced installation time, they are particularly well-suited for systems where regular dismantling or maintenance is expected.

What is a Plate Flange?

A Plate Flange is a flat, circular disk with bolt holes around the perimeter, used to bolt pipes, valves, pumps, or other equipment together in a piping system.
They are typically made from a single cut plate and do not have a hub, making them cost-effective and easy to fabricate for low-to-moderate pressure applications.

Plate flanges are ideal for connecting piping sections that need frequent disassembly for inspection, maintenance, or replacement.

Simple Construction → Made from cut and machined plate material.
Economical Option → Lower cost compared to forged flanges.
Ease of Fabrication → Quick production for standard or custom sizes.
