Key Features
- Vinyl ester FRP construction with thick abrasion-resistant internal liner.
- Smooth-turn branch connections (radius tees) to reduce turbulence and erosion.
- Support for maintenance loads (reinforced laminate for walkways).
- Multiple bolt-flanged nozzle mounts for easy replacement.
Benefits
- Uniform Spray: Precisely drilled nozzle ports ensure even coverage across the tower. Reduces un-scrubbed zones.
- Durable: Thick FRP resin and glass give excellent resistance to slurry wear (better than rubber-lined steel).
- Energy Savings: Smooth internal flow and optimized nozzle design lower pumping power and pressure drop.
Applications
These components are used inside FGD scrubbers and reaction towers in power plants. Spray headers deliver limestone or lime slurry to absorption zones; nozzles atomize the slurry for flue gas scrubbing. They are also used in spray chambers for wastewater treatment and cooling towers. FRP headers can be paired with FRP riser piping and pumps to form a complete FRP liquid distribution network.
Technical Specifications
- Materials: FRP (vinyl ester or epoxy) with optional epoxy vinyl ester liner ≥150 mil.
- Sizes: Custom lengths and pipe diameters (commonly 4″–24″) with flanged ends.
- Nozzle Types: Choice of single-orifice, full-cone, hollow-cone or flat-fan nozzle profiles. Nozzle flow rates and angles to suit process.
Unique Selling Points
We fabricate spray headers to exacting tolerances. For example, our proprietary smooth-turn branch connections significantly reduce internal turbulence and wear. Each header is fully supported to handle maintenance loads. We also supply corrosion-resistant nozzles (e.g. PVDF, polypropylene) to complement our FRP headers for extreme services.
