Center Pipe Wedge Wire Filter Element Inner Screen

Product Description

What is wedge-wire and how it's made
 

 

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 suit your application requirements. The pin point control over the specifications of the slot is what allows Yongkun 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. Yongkun 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,  Copper Nickel, Hastelloy C-276, Alloy B-3, 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.

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.

Construction Profiles
We offer numerous combinations of profile wires and support rods. Wedge Wire Screen is created by wrapping a profile wire cylindrically around longitudinally placed support rods. The wide range of apertures between the wires and rods allows us to design a screen according to our customers' technical or structural specifications.

 The benefits of using wedge wire:  
- Extended lifetime
- Slot during abrasive operation on the screen surface does not change
- Capability to withstand heavy loads
- High open area
- Less prone to clogging
- Perfectly smooth and flat surface
- High precision of execution Increased capacity and more precise separation
- Self-cleaning effect
- Low pressure loss
- Increased efficiency
- Permanence of exploited resources
- Lower capital cost and maintenance
