Tube wells generally fails due to problems like corrosion and
encrustation associated with conventional pipes. Due to
corrosion the strainer screens get damaged and the sand
particles enters along with the water. Due to encrustation, pipe
diameter as well as effective area of screen get reduces and
hence tube well becomes un-service able in short period. These
problems are totally eliminated in Supreme casing pipes made
from specially developed PVC compound. Supreme casing
pipes offer superior performance at a lower cost and becomes
the prime choice of the customer.
Supreme offers varieties of pipes for bore-well applications to
cater every need of bore-well sector which includes Casing
pipes as per IS 12818, Casing pipes as per ASTM D : 1785,
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. Column pipes for submersible pumps
are also offered to lift the water from the bore -wells.
Very encouraging results have made the Supreme uPVC casing pipes well accepted by civil engineers, drilling contractors and government/semi-government departments. They are ideal for domestic, irrigation, industrial, public and mining wells, etc.
Features & Benefits
- Excellent corrosion resistance:
Unlike steel pipes, uPVC casing pipes are totally immune to corrosion and offer good resistance to aggressive elements in the soil which could cause encrustation of well screens.
- Light in weight:
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 provided with good quality threaded joints, thus they can be 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.
The material of the pipe is non-toxic and hence does not impart any taste, odor 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.
uPVC is non-conductor of electricity, which eliminates any elector 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.
Apart from all the advantages listed above, 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
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 type 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.
