What is wedge-wire and how it’s made 

Wire-Spool#9-(1)_fin.gif

Wedge wire screens are manufactured by resistance welding V-shaped wire on support rods. Our wedge wire screen begins with the highest quality raw wire then is made into screen that is cut, shaped, fabricated and cleaned.

Wedge wire can be ordered as raw screen material or fabricated to a finished product to suite your application requirements. The pin point control over the specifications of the slot is what allows Federal Screen to provide its customers with highly accurate flow distribution and effective media, debris and sediment filtration. Support Rods running perpendicular to the wrap wire strengthen and maintain the proper design configuration of the screen allowing it to handle intense pressure demands.

Our Wedge Wire Screen is designed to control various processing conditions including volumetric flow rate, minimum dimensional media retention, minimum open area and fluid pressure capabilities. Federal Screen is able to professionally work a large variety of stainless steels and alloys into both standard or customizable screen applications and accessory products.

Screens are available in slot sizes ranging from 0.001 in. (25μm) up to (1/2”).

The most common material of construction is 300 series stainless steel, however many exotic alloys are available upon request such as 321SS, Duplex & Super Duplex SS, Alloy 20,  Hastelloy C-276, Alloy B-3, Titanium, Monel 400. 
 

Screen diameters range from 0.750 in. to 38” in size straight from our machines. Screen can be fabricated in upwards to 52” O.D in two or more sections depending on the requirements.

Screens also are made in various different configurations, including cylindrical, flat, specialty shapes or curved.  Many different variations of wire and rod sizes/profiles can be selected to develop the exact screen of your choice. A wide range of wire and rod shapes make it possible to achieve the optimum balance of strength, open area, abrasion resistance and filtration efficiency.

Our screen can be welded to nipples, couplings, pipe, or flanges.

The fabricated and welded construction makes for durable quality vessel internals and media retention products. Wire mesh and perforated pipe may be less expensive initially, but wedge wire screens offer easier installation and long-term operating and cost benefits. Any process or vessel requirements can be accommodated, such as vertical or horizontal vessels.
