What Are Headers and Manifolds?
Headers (also known as manifolds) serve as the main conduit used to:
- Distribute incoming flow evenly to multiple downstream pipelines
- Collect flow from multiple lines into a single outlet
- Maintain pressure uniformity across cross-connected systems
- Provide stable flow to filtration media, membrane modules, scrubbers or reactors
FRP/GRP headers are widely preferred due to their superior corrosion resistance, structural durability and compatibility with varying process fluids.
Why FRP/GRP Material for Headers?
✔ Corrosion-Proof Construction
FRP/GRP headers resist:
- Acids
- Alkalis

Significantly lighter than metal headers, allowing:
- Lower civil and structural load
- Easier handling during installation
- Faster maintenance
✔ Excellent Hydraulic Behaviour
Smooth internal surface ensures:
- Low friction loss
- Uniform flow distribution
- Minimal scaling and deposition
✔ Tailor-Made Configurations
Customizable in:
- Diameter
- Port quantity
- Orientation (top entry / bottom entry / side port / radial)
- Length
