Tops Customs Wedge Wire Vessel Lateral Assemblies for Water Treatment & Media Retention

Our wedge wire vessel lateral assembly is produced advanced welding process. Comparing with the traditional intermediate drainage device, wedge wire vessel lateral assembly has a large flow area, uniform water distribution, high mechanical strength, high-temperature resistance, pressure resistance, anti-aging, and corrosion resistance. Even when the branch pipe is bent, there will be no running resin.

The gap size can be designed according to resin size.

Wedge wire vessel lateral assemblies including following:

  • Headers lateral assemblies
  • Hubs lateral assemblies
  • Spool lateral assembly
  • Intake lateral assembly
  • Pipe based laterals
  • Custom designs lateral laterals

Hub Radial Lateral Assembly-Effective Distribution and Collection

Hub Radial Lateral Assembly is mounted on the top or bottom vessels, is an economical possibility for smaller vertical vessel. Our every Hub Radial Lateral Assembly can be specifically designed for your application and serves both as a collector of down-flow service and a distributor of incoming backwash water. And, for counter-current flow, flow with an inlet at the bottom of the vessel, the arrangement is inversed with the distributor at the bottom of the vessel and the collector at the top of the vessel.

The wedge wire screen can be perforated pipe based for high pressure vessels, or designed to evenly distribute flow over the entire screen area.

Header Lateral Assembly- Designs For Horizontal Vessels

Header lateral assembly consist of a series of wedge wire screen laterals attached to a central header, it allows process engineers to design for uniform flow through the treatment media at a wider range of rates and for a variety of vessel sizes and shapes. Header lateral design for horizontal vessels is also used for square or rectangular underdrains.

Header lateral assembly can be either side mounted or centrally mounted, it provides most effective uniform distribution or collection for vertical vessels. Header lateral assembly system can be designed to accommodate a variety of process conditions and requirements, while maintaining their characteristics of high distribution efficiency.

Wedge wire screen laterals spacing, numbers, length, diameter and slot opening size are based on individual system needs. Slot sizes can be any width from 0.002 inches and up in 0.001 inch increments.

Wedge Wire Screen Laterals-Top Customized &Designs For Different Requirements

Except of header lateral assembly, hub radial lateral assembly, if customers only need the wedge wire screen laterals, types of customized wedge wire screen laterals and resin trap also available from us.

Our wedge wire screen laterals can be as small as 0.75inches in diameter or larger.

Wedge wire screen Laterals attach to headers of hubs with either threaded fittings, couplings or flanges. A perforated pipe-base can be used inside the screen laterals for increased collapse resistance and enhanced flow distribution.
