Bore well Application -

The System
Tube wells generally fails due to problems like corrosion and encrustation associated with conventional materials Due to corrosion the strainer screens get damaged and the sand particles come out along with the water. Due to encrustation, pipe diameter as well as effective area of screen get reduces and hence tube well becomes unserviceable within few years. These problems associated with conventional materials are totally eliminated in Supreme casing pipes made from high quality PVC resin. Supreme casing pipes offer superior performance at a lower cost and become the prime choice of the customer.

Supreme offers varieties of pipes for bore well applications to cater to every need of bore well sector which includes Casing pipes as per IS 12818, Ribbed screen casing pipes for tube wells. SDR casing pipe series for shallow depth applications as per company standard, Plain pipes as well as screen (slotted) pipes are available in every category of casing pipes. (Slotted pipes can also be used for rainwater harvesting). Submersible column pipes for submersible pumps are also offered to lift the water from the wells. The advantages of Supreme uPVC water well casing, and screen pipes are given below.

Features & Benefits

  • Excellent corrosion resistance:
    Unlike steel pipes, uPVC is totally immune to corrosion and offer good resistance to aggressive elements in the soil and normal chemical action, which could cause encrustation of well screens.
  • Lightweight:
    These pipes are light in weight and hence transportation and installation becomes much easier. This is a major advantage particularly in remote rural areas where road communications are not satisfactory and well construction is a one-time exercise.
  • Quick and convenient installation:
    These pipes are equipped with good quality threaded joint. Thus Supreme casing pipes and screens are easily assembled and installed where drilling is done by hand with light weight drilling rig or even with large capacity drilling machines.
  • Excellent Stiffness:
    These pipes have excellent stiffness and meet all the mechanical properties as per the IS 12818 specifications. These pipes have excellent hydrostatic collapse pressure i.e. capable of withstanding the external hydraulic pressure they would be subjected to during well construction.
  • Non-toxic:
    The material of the pipe is non-toxic and hence does not impart any taste, odour or colour. It does not release any harmful substances to water from well, which could pose health problem. It is free from bacteria and hence absolutely safe for carrying drinking water.
  • Non-conductive:
    uPVC is non-conductor of electricity, which eliminates any electro chemical action with ground water, which could cause encrustation of screens.
  • Longer Lasting:
    Being free from rusting, weathering and chemical action and due to excellent mechanical properties, Supreme casing pipes lasts for lifetime.
  • Economical:
    When all the advantages listed above are taken into consideration, it would be seen that in most cases Supreme uPVC casing pipes and screens provide the best cost benefit ratio when compared to other materials or even alternative uPVC casing pipes available in the market.

 

Casing Pipes conforming to IS 12818:1992

Pipes

These pipes are manufactured as per BIS standard and are available in deep blue colour. One end of the pipe is male threaded where as other end is female threaded socket. Threads are either V or trapezoid type and protection caps are provided on the threads to protect the threads in transit. Two types of pipes i.e. Shallow Well (C.S.) and Medium Well (C.M.) are available. Shallow Well pipes can be used for depths upto 80 meters and Medium Well pipes can be used upto 250 meters.
