Wedge Wire Lateral Assemblies for Under Draining Filtering


Wedge wire screen is widely used in the under draining applications with the features of effective filtering and screening performance. Wedge wire lateral assemblies are a typical screen type used in the under draining.

Wedge wire lateral assemblies, also called header lateral assemblies, are assemblies of horizontal herring bone style wedge wire screen laterals and vertical secured round hub. The screen lateral has inherent even pattern, which is made of stainless steel, hastelloy alloy steel and other alloy steels. The screen lateral has various slot size, wire size and diameters to suit common or customized applications.

The wedge wire screen lateral has two type: threaded ending wedge wire screen lateral and flange ending wedge wire screen lateral. Threaded ending wedge wire screen laterals are composed of a solid cap on one end and a threaded pipe connection on the other end. The flange ending wedge wire screen lateral is composed of solid cap on one end and a flange. The different design make it possible to suit different applications and machines.

Because of the different ending of wedge wire screen lateral, the connection type is different. Commonly the wedge wire screen laterals are installed onto the vertical hub by threaded. Sometimes, the screen laterals are bolted onto the round hub through flanges on the screen laterals and round hubs.

Sometimes, the threaded ending wedge wire screen laterals are installed on to a hub with flanges. And the flanges are connected to the vertical hub flange by the bolts and nuts. The flange can be top flange or bottom flange. All the designs are used to suit different position and requirements of machine.

Hub radial laterals
There are another type of lateral assemblies, which are named as hub radial lateral. It is composed of several screen laterals and a central hub. The hub radial lateral assemblies has two main ending types: threaded ending types and flange ending types.

Eight wedge wire screen laterals are connected to the central hub by threaded connection.
WWLA-07: Threaded connection type hub radial lateral assembly.
Four wedge wire screen laterals are connected to the central hub by flange connection.
WWLA-08: Flange connection type hub radial lateral assembly.

Hub radial lateral assemblies have lots of specs, including the slot size, screen lateral lengths and assemblies diameter. Additional, the quantity of screen laterals can be customized. There are four common type of hub radial lateral assemblies, you can refer to them and if you want other types, just tell us and we will customize them for you.
