Johnson Screen Suppliers and Manufacturers

They consist of v-shape profile wire and the longitudinal support rods. Each intersecting point of these wires is fusion welded, so it has sturdy constriction and good mechanical property.The v-shape section plane can avoid blockage, and make sure of the unimpeded water. The consecutive slot have more open area, and it can reduce the speed of the water entering to aviod the sand entering the screen under the great pressure, so it can filter sand better.Meanwhile, the slot can change according to the real condition of the earth.

Advantages of using Profile Wire Water Well Screens : When compared to conventional slotted pipe, Water Well Screens have superior open area due to their continuous slot openings. The benefits of which will : * Reduce energy consumption and increase water flow. * Reduce erosion of entry surfaces and increase well life. * Allow a uniform and efficient well development. * Reduce significantly potential pump damage and subsequent maintenance costs. Water Well Screens offer many advantages including: A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone (the aquifer) A "V" shaped profile wire which avoids clogging and ensures an uninterrupted flow. A uniform and efficient well development due to the continuous slot opening. Uses:The strainer is a kind of filtered water tubing with the perforation. it can use with the deep well pump, dive the water pump, also may use in the water-treating equipment, water supply, the environmental protection, Polluted water and sundries separating, the petroleum industry, crude oil refining, mineral processing, foodstuff processing, and so on the organic solution recycling filters.

Johnson screen filter Introduction of Johnson screen filterJohnson screen filter 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 intersecting point of these wire fusion welded, , which creates the robust construction and excellent mechanical performance.The v or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening, hence the screen allows water(oil) to enter your well freely in ample quantities, while at the same time keeps the majority of sand and gravel out of the well.The slots can be changed according to different strata. Advantages1)Non-clogging constructionThe 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 areaThe 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 lifeWire and support rods are all-welded, which makes wedge wire screens (Johnson type screens ) more robust and longer life. 4)Excellent construction strengthThe 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. SpecificationsSlot Size (mm): 0.10, 0.15, 0.2,0.25, 0.30-3 or as per customers requirement. Material: carbon steel, stainless steel (304, 316,304L,316L etc.).Unit length up to 6m (or according to clients' requests).

Johnson Screen Resin Trap Strainer Wedge Wire Resin Traps Wedge Wire Screen PRODUCT FEATURES Johnson screen pipe resin trap strainer used in water treatment processes namely in 'Ion Exchange' and other numerous media filter systems, Completion Products offers a Resin Trap Screen. This screen system is primarily used as a safety device and is positioned immediately after the outlet nozzle of the vessel/reactor. Johnson screen pipe resin trap strainers are very effective in wells of this type since they can be manufactured with very small slot size and yet still maintain the necessary open area to minimize friction head loss. Most continuous wire wrap screen is manufactured from stainless steel rather than carbon steel in order to avoid problems which often leads to accelerated corrosion.

Characteristics of johnson screens: Easy clearing The narrowest part of the aperture comes at the top and the steady opening out from that point promotes easy clearing. Lateral strength Increases rapidly with the width of the profile and sufficient is needed to avoid the likelihood of the wedge wires being bent sideways and the accuracy of the slot being thereby lost. Load carrying capacity or vertical strength Increases rapidly with the depth of the profile and is needed to a greater degree than is lateral strength Percentage open area For any given aperture size this depends on the number of apertures per foot width of johnson screen. The wider the profile the fewer the apertures, and the less is open area - likewise the smaller the number of pressed wedge wires per foot, the greater the open area. Wearing life With abrasive materials the top surface of the profile becomes worn away and inevitably the aperture must increase. With a small angle of opening the increase is gradual, but with a large angle it is rapid. The apertures quickly reach the oversize limit and the working life is reduced.
