Frequently Asked Questions


HOW DO YOU FIGURE OUT THE OPEN AREA OF SCREEN?

Wedge screen open area ratio (OA) is calculated using the following formula (multiply by 100 for percent)

HOW MUCH DOES IT COST?
All our products are custom manufactured mainly due to the fact that there is limitless possible combinations of wire profile, slot size, material choices and lengths. Depending on the applications, the cost per unit varies and must be calculated on a per-job basis.


WHAT IS THE STANDARD SLOT SIZE?

There is no real standard size. Due to the large range of applications we deal with on a day to day basis, each requires very different slot sizes. Typically, the rule of thumb for most applications is to use a slot size that is half the size of the smallest media particle.


DOES WEDGE WIRE HAVE LOW HEAD LOSS

The high open area of wedge wire screen contributes to low head losses through the screen surface.


IS WEDGE WIRE NONCLOGGING?

Wedge wire screens are fabricated by helically wrapping parallel support rods with a continuous V-shaped wire. The uninterrupted slot formed with this procedure allows only two-point contact of particles in the screen slot to minimize clogging. This means maximum effective flow area and operating efficiency is maintained.


WHAT ARE THE STANDARD TOLERANCES FOR SCREEN?

Specialty tolerance maybe requested, especially on custom machined items.

Tolerance of O.D:0.005”

Tolerance of slot size:+/- .002”

Fabrication:+/- 1/16” (2 PL DEC = 0.020”, 3 PL DEC = 0.010”)

Angles:+/- 1 degree
