Precision Hub & Header Lateral Systems
Ensure uniform collection and distribution in your process vessels. Our wedge wire laterals prevent dead zones, optimize media utilization, and offer superior mechanical strength for backwashing.
High-Efficiency Vessel Underdrain Solutions
Hub and Header Laterals are critical internal components designed for pressure vessels, reactors, and filters. By utilizing wedge wire (V-wire) technology, these systems provide a continuous slot that ensures consistent flow rates and prevents the loss of expensive resins or filter media.
Whether you need a Radial (Hub) configuration for circular tanks or a Fishbone (Header) layout for rectangular or large cylindrical vessels, our systems are engineered to handle high pressure drops and intensive backwashing cycles.
Two Main Types
Hub Lateral Systems
Ideal for smaller vertical vessels. Laterals radiate from a central hub, ensuring even coverage across the entire bed diameter.
Header & Lateral Systems
Best for large diameter vessels or horizontal tanks. A central header pipe with multiple side laterals ensures balanced flow across large surface areas.
Engineering Advantages
Uniform Distribution
Precisely calculated slot area ensures no "channeling" or dead zones in the media bed.
Resin Retention
Extremely fine slot options (down to 0.05mm) reliably retain even the smallest ion exchange resins.
Easy Installation
Modular design allows for assembly inside the vessel through standard manways.

Frequently Asked Questions
We typically recommend a slot size that is half the size of the smallest media particle (e.g., if resin is 0.4mm, we use 0.2mm slots).
Yes, our segmented design allows the system to be taken through existing manways and assembled inside the tank.
For high-stress applications, we recommend fully welded or heavy-duty flanged connections.
