PVC Well Screens, Casings and Accessories - Johnson Screens

PVC is the material of choice for a growingnumber of applicationsPVC offers a combination of economy,light-weight design and flexibility thatmakes it a cost-effective solution for:• Water wells• Water monitoring wells• Environmental• Soil vapor extraction• Sparging - air or oxygen• Bioremediation• Free product recovery• Groundwater extraction• Drainage and dewatering• Leachate collection• MiningPVC is also used when sampling forheavy metals, since it will not leachmetals or contaminate the samples. Italso has the advantage over steel whenencountering corrosive fluids.Among Johnson Screens fabricationoptions are:• PVC casing and well screensfrom 0.50 to 18 in. (13 to 400 mm)diameter• Plain end, flush joint, NPT or customthreaded• Threaded products supplied in layinglengths• Screen openings from 0.005 to 0.50in. (0.01 to 13 mm)• Standard and custom lengths up to20 ft (6.1 m)Johnson screens - environmentally friendly,environmentally awareThe environmental and remediationmarkets require special manufacturingtechniques and processes.Johnson Screens manufactures acomplete line of PVC well productssuited for groundwater monitoring andremediation.With the same quality and reliabilitythat accompanies all Johnson Screensproducts, the environmental andremediation product line includes wellscreens, casings and accessories.To meet industry requirements,Johnson Screens provides the following:• No printing on screen or pipe• Cleaned and bagged• Flush thread connections• O-ring pre-installed• Box or bulk package optionsavailable3

The critical differencein Johnson screens ® pvcscreens is open areaJohnson screens Pvc vee-wire ® well screensCommonly used in shallow wells,Johnson Screens sonic welded PVCVee-Wire screens present higher openarea for given slot than any other nonmetallicscreen available.More economical than metal screens,PVC Vee-Wire screens resist corrosionfrom salts and gases commonly foundin either salt or fresh water, and areresistant to acid treatments commonlyused to clean wells.PVC screens are furnished with standardflush threads or plain ends for connectingto standard PVC fittings.Sizes range from 1.25 to 8 in. (32 to 203mm), and screen slot size can be assmall as 0.005 in. (0.13 mm) and up, percustomer specifications.End FittingsPVC screens are supplied with standardflush threads or plain ends for connectingto standard PVC fittings.Better well developmentIt is important to remove fines from thefilter pack or formation to increase thewell’s porosity, which enhances wellefficiency. For this to be effectively done,development energy must pass throughthe screen with minimum interference.This requires high open area.More open AreaJohnson Screens PVC Vee-Wire screenshave more open area per foot than anyother non-metallic screen available.This allows more water to enter at lowervelocities, which reduces turbidity andenables a more representative sample tobe collected.Johnson screens Pvcvee-pack pre-packed screensSome subsurface conditions, suchas heaving, caving, silty sand makeconventional gravel pack placementdifficult or impossible.The solution is Johnson ScreensVee-Pack screen. The Vee-Pack containsan integral gravel pack that is held inplace between two concentric screens.This assembly is then installed in a singleoperation.Standard features of the Vee-Packinclude:• Smaller borehole• Slot spacing as small as 0.008 in.(0.203) mm• Standard 2 and 4 in. (51 and102 mm) sizes available• Reduces cutting disposal• Factory-installed re-sieved silicasand filter pack is uniform, withoutvoids• Fine-grade pack allows sedimentfreesampling• High screen open area• Sonic-welded constructioneliminates solvents which can affectsample integrity• Schedule 40 and 80 flush threadsavailable• Thread-on points ease installationin heaving sands4
