Fiberglass Flanges

Fiberglass flanges are indispensable key connecting components in fiberglass piping systems, used to connect and seal pipe sections to each other, and pipe sections to valves, pumps, or other equipment.

There are two main types of fiberglass flanges, which differ in structure and performance:

1. Integral Flange

Advantages:

Highest strength: Integral molding, good structural integrity, and strong load-bearing capacity.

No leakage path: Avoids the bonding interface, resulting in extremely high sealing reliability.

Good fatigue resistance: Better able to withstand vibration and pressure fluctuations.

2. Adhesive Flange / Loose Flange

Manufacturing process: The flange is manufactured separately from the pipe, and then a high-strength adhesive is used to bond the flange to the outer wall of the pipe.
