Borewell Casing Pipes
APPLICATIONS
- Borewell pipes are used to extract ground water for farms and fields.
- For connections to residential & commercial buildings, public places etc.
MAJOR ADVANTAGES
- Easy to transport, store, handle and install.
- Bore diameter remains constant, ensuring constant.
- Saves labour & installation cost.flow over lifetime
- Drinking Water supply and distribution.
- Smooth bore ensures higher flow compared to G.I. pipeline.
- Superior resistance to most of the chemicals, no scaling, of the same size. No clogging. makes the system almost maintenance free.
- Long life.

DO’S & DONT’S
JOINTING & INSTALLATION.
- Ensure that pipes threads are proper and clean it with normal water to avoid forceful jointing.
- Ensure that rubber seal is properly sealed in its position, without any twist/cut while tightning the threads to avoid leakages.
- Before jointing the pipes with pump, it is recommended to provide pump guard between pipe coupler and pipe metal adapater.
- Assemble the TRUBORE G I metal adapter with pump.
- During assembly of the pipe.,initially hold the pipe coupler with hands & tighten it, for final jerk always use rope strap wrench to tighten the pipe properly.
- Fix a nylon rope to cast iron adapter as a safety measure against failing of submersible pump due to mishape.
- Clamp the pipe below coupler (at defined location at pipe) at the time of lowering Trubore rising main pipe into the borewell.
- Always use chain pulley for lowering Trubore rising main pipe.
- Don’t use any chemical for cleaning the pipe thread.
- Don’t apply lubricant on borewell casing pipe thread.
- Don’t over-tighten the joints to avoid breakages.
- Don’t use pipe/chain wrench to tighten the joints.
- Don’t dump gravel at a very high rate to avoid excess abrasion.
- Don’t use any chemical for cleaning the pipe thread.
- Don’t use agri-pipes(with solvent cement joint) for borewells, as their mechanical strength is not designed for this application.
- Don’t hammer the pipes during assembly.
HANDLING, TRANSPORTATION & STORAGE.
- Pipes shall be stored in shade on resonably flat surfaces, free from sharp objects.
- Don’t hammer the pipes during assembly.
- Don’t dump the pipes over each other.
- Don’t remove the packing & thread protection covers of borewell pipes till the time of installation.
- Don’t drag/throw the pipes during handling to avoid thread damages.
GUIDELINES FOR INSTALLATION
OF SCREEN & CASING PIPE.
- Drill the bore of the required size & depth in the gorund using the method of auger drilling/water jet boring/hydraulic rotart drilling/core drilling. During drilling, care should be taken that it is vertically straight down without any bends.
- To contstruct the bore/tube well, CASING/SCREENING & RISING MAIN pipes are required.
- CASING pipes are highly recommended in the area where loose soil & slit/loose boulders & loose stones are prevalent.
- Fit the rubber gasket properly on the space provided on the ribbed screen/casing pipes.
- Fit C damp below the bell end on the pipe and lower the assembly done with the help of chain pulley block (Provide sand trap with endplug as necessary).
- Ater lowering the pipe up to the clamp level, fix the rubber gasket on another pipe & tighten it gently with the lowered pipe. After tightening, use pipe/chain wrench for proper jointing, but do not over tighten.
- Fix the next clamp with the pipe above and bend below and connect the chain pulley with clamp.
- Remove the clamp of lowered pipe & start lowering further.
- Repeat the jointing method till the required depth of borewell.
- Centering guide to be fitted wherever necessary.
- Fill the gravel between pipe & bore hole.
GUIDELINES FOR INSTALLATION
OF RISING MAIN PIPE.
- Once screen & casing pipes are installed properly, follow the below guidelines for installation of PUMP & SUBMERSIBLE DELIVERY PIPE.
- Before starting installation, pre-check if submersible pump is in good working condition.
- Join the Trubore metal adapter with the submersible pump with the help of chain wrench
- Before starting the pipe assembly, clean the pipe threads with normal water to avoid forceful jointing.
- Before joining the pipe with pump, ensure the pump guard is installed properly between pipe coupler & pump metal adapter.
- Assemble SUBMERSIBLE DELIVERY PIPE with pump, always use strap wrench/rope for last jerk.
- Fix a nylon rope to cast iron adapter as a safety measure against falling of submersible pump due to mishap (run the nylon rope throughout the borewell length & tie it with top clamp).
- Fit the C clamp below coupler(at defined location on pipe) & lower the assembly inside the CASING pipe carefully with the help of a chain pulley.
- Once casing pipe will be lowered in the borewell up to the clamp level, fix the rubber ring on the other pipe & tighten it gently with the help of rope/strap wrench, till half of the ring gets inside the coupler.
