Product Features Resistant to corrosion Non chemical contamination Supreme Flexibility Further DetailsAjay uPVC ribbed screens and plain casing pipes for application in tubewells, besides various government aided schemes of medium irrigation projects are manufactured by house of A.I.C. who are in the field of plastic extrusion for past 4 decades. Produced with strict quality control, these pipes are made according to International standard British standard ASTM standard German standard (DIN 4925 Part-I/II) Indian standard (IS 12818: 1992). The plant is equipped with cincinnati milacron twin screw extruder machine capable of producing pipes from 20mm to 250 mm in 2.5 kgf/cm2 pressure classes. ApplicationSoil corrosion is a major cause for short life of Tubewells. Due to its exceptional resistance to soil corrosion, unplasticised poly vinylchloride (uPVC) has firmly established itself as the best alternative to the more traditional materials used for well screens and casing. uPVC ribbed screen and plain casings have swiftly been accepted by the experts in the field of irrigation. Advantages Corrosion resistance Non chemical contamination No need of protective liners, coatings, encasements or cathodic protion Low thermal conductivity Flexibility Variety of jointing methods Non-Toxic Biological resistance Better resistance to water hammer / surge pressures Threading of Screen and Casing pipesAjay uPVC ribbed screens and casings can be easily and quickly jointed as ends are theaded. The joints have good tensile strength and can hold the weight of the suspended assembly. This screen and casing pipes shall have male threads at spigot end and female threads at the socket ends. Screen and casing pips of nominal diameter from 40 to 80 mm shall have threads in accordance with whitworth pipe thread. Screen and casting pips of nominal diameters of 100 to 200 mm shall have threads in accordance with basic profile for metic trapezoidal thread. Rubber sealing element of diameter ensuring secure fit shall be used with the trapezoidal treads to seal the joint. Use thread lubricant/Soap for easy tightening. Remove dust from thread roots. InstallationLowering of the uPVC ribbed screens and plain casing is similar to that of mild steel pipes. However care must be taken to ensure that the pipes are perfectly upright which would ensure trouble free working of the tube well. The pipes should not be driven using external force such as hammering etc. Use back wash method while gravel packing the well. Avoid generating excessive external pressure while gravel packing. The external pressure should be equalized. Exercise care during removal of drilling muds during jetting and surging not to create excessive differential pressure across casings.
