Pipes for Bore well application

Tube wells generally fail due to problems associated with conventional materials like corrosion and encrustation. 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 SFMC casing pipes made from high quality PVC resin. SFMC casing pipes made from high quality PVC resin. SFMC casing pipes offer superior performance at a lower cost and become the prime choice of the lower cost and become the prime choice of the customer.

SFMC 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, Hi-tech Wellguard structured-wall casing pipes conforming to IS 12818, Ribbed screen casing pipes for tube wells.

The advantages of SFMC uPVC water well casing, Wellguard structured-wall casing and screen pipes are given below.

Features and 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. Wellguard pipes are further lighter than alternative solid wall PVC casing pipes. 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 either equipped with good quality threaded joint or easy-fit joints for Wellguard casing. Thus SFMC 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 sue to excellent mechanical properties, SFMC casing pipes lasts for lifetime.
Economical : When all the advantages listed above are taken into consideration, it would be seen that in most cases SFMC 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 Grey colour. One end of the pipe is male threaded where as other end is female threaded socket. Threads are 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.

SDR Pipes
These economical pipes manufactured as per company standards are available in Grey colour. These pipes are suitable for shallow depths where soil formation is favorable. Use of these pipes for particular application should be examined on case to case basis. One end of pipe is plain end where as other end is socketed for solvent weld joint.

Ribbed Screen Pipes
These pipes are provided with V shape ribs on its exterior surface. Special design of this structure with fine slots provided on pipe prevents entry of even small particles and hence permeability of the screen gets properly maintained. These pipes are generally used in combined wells or used for specific formation where normal screen pipes do not work. These pipes are provided with threaded joints with one end of the pipe male threaded and another end with female threaded socket.

uPVC column pipes submersible pumps
These pipes have been specially designed and manufactured under stringent quality standards. They are tested to withstand system load comprising of pump, water and pipe weight with adequate factor of safety. Due to unique design of square threads, they can withstand considerable shock and jerk load during operation.

SFMC submersible column pipes offer many advantages like -
Light Weight,
High Tensile ZLoad Capacity,
Leak Proof Joints and Long Life
Economical and hence emerges as the best option for conventional metal pipes.

These pipes are provided with square threads with male threads on one end and female threaded socket on another end upto 1½ size and with separate integral female threaded coupler for 2” and 2½” size. These pipes are available in light duty and standard duty. Light duty pipes can be used upto 400 feets and standard duty pipes can be used 900 feets depth.
