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.

Johnson ScreenFeaturesJohnson screen (also known as wedge wire screen, or water well screen, or wire wrapped screen) 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.Use area of the Johnson screensThe 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, the environmental protection, the sea water transforms into the industrial water and life use water desalination treatment, running water treatment, water softening treatment, the petroleum industry: The petroleum product terminal filters and the chemical acid, the alkali liquid filters, the ethyl alcohol and so on the organic solution recycling filters. CharacteristicsJohnson Screen consists of V-wire and the longitudinal support rods. Each intersecting point of these wires is fusion welded, so it has sturdy construction 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 avoid the sand entering the screen under the great pressure, so water well screen can filter sand better. Materials: Galvanized carbon steel(LCG), stainless steel (304,304L,316,etc.). Diameter: From 30-1500mm /(114.3mm- 4 1/2",168.3mm-6 5/8", 219.1mm- 8 5/8", 244.5mm- 9 5/8", ) Slot Size (mm): 0.02mm-15mm or as customers requirement.Unit length: 1- 6m, 5.8m fit for the container.Johnson screeScreen Size(in)Inside Diameter (in)Outside Diameter(in)OD of Female Threads End (in)2225/823/43335/833/44445/843/45555/853/46665/878885/891/41010103/4113/81212123/4133/814131/814 161516 2018 3/420
