Wedge Wire Screen is  also called Johnson screen. Wedge wire screens (Johnson Type Screens) are manufactured by a v or wedge shaped wire around an internal array of longitudinal support rods. The world advanced all-weld technology is used with each interesting point of these wire fusion welded, which creates the robust construction and excellent mechanical performance. It consists of wedge wires resistance welded onto support rods, which can provide more open area  and these non pl ing well screens have a tight slot tolerance. The specific continuous slot construction aims to optimize flow rates  and minimize clogging .Each wedge wire screen product is  designed to suit the specific requirements of the customer. Our manufacture wedge wire screens are available  for a variety of industries, including water well production,water treatment,food and beverage,oil and gas,pulp and paper,mineral and aggregate processing,refining and petrochemical.

Advantages

1Non-clogging construction: The V-shape section plane of wedge wire screens (Johnson type screen) creates the continuous slot, which can avoid blockage and make sure of the unimpeded water.

2 Large filtering area: the consecutive slot of wedge wire screens (Johnson type screens) has wider open area, and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so it can control sand better, which can increase the water yield and prolong service time of the well.

3 long service life: Wire and support rods are all-welded, which makes wedge wire screens (Johnson type screens ) more robust and longer life.

4 Excellent construction strength: The longitudinal support rods and the continuous slot make the wedge wire screens (Johnson type screens ) can be fabricated according to customers’ requirements.

Note: Wires, rods and slot sizes can be customized according to customers’ requirements.
