Advantages of Lead-Free Column Pipes
Lead is highly toxic and harmful to various body systems, including the nervous system, reproductive system, and kidneys. Long-term exposure to lead can cause high blood pressure, anaemia, and even lead poisoning. Children, pregnant women, and developing foetuses are particularly
vulnerable, as lead interferes with calcium and Vitamin D metabolism, leading to severe health consequences.
- Prevent lead from leaching into water, ensuring safe potable water.
- Reduce the risks of intellectual disabilities and behavioural issues in children.
- Protect pregnant women and their unborn babies from lead exposure.
- Avoid fatal outcomes such as convulsions, coma, or death caused by high lead levels.
Switching to lead-free piping systems, like Astral’s, is important for the safe and sustainable transportation of drinking water. It is a step towards healthier lives and a safer environment.
Why Choose Astral Bore-Well Pipes For Submersible Pumps?
Astral has redefined the standard for bore-well pipes through precision engineering and advanced robotics. By employing automated CNC machines, we produce unique square threads that provide a superior grip and the high tensile strength necessary to support heavy submersible pump assemblies. This meticulous manufacturing ensures that every column pipe offers consistent quality and enhanced durability.
1. Structural Integrity and Innovation
To ensure long-term reliability, Astral uses a specialised ‘Thick and Thin’ process. This increases wall thickness at the threaded ends. This compensates for any strength lost during the machining process. This design allows the pipes to withstand significant vertical loads and dynamic pressures. This makes them the best pipe for borewell installations in demanding environments.
2. Reliability and Safety
Leak-Proof Performance: Each joint features high-quality EPDM ‘O’ rings. These create a watertight seal while absorbing operational vibrations and maintains pump efficiency without the need for frequent maintenance.
Eco-Friendly Composition: Developed using Japanese technology, these best-quality borewell pipes are 100% lead-free. This commitment to non-toxic materials ensures that drinking water remains pure and groundwater remains uncontaminated.
3. Versatile Applications
Astral offers an extensive range of sizes, from 1″ (25 mm) to 6″ (165 mm), across various pressure classes including V4 ECO, Medium, Standard, and Super Heavy. Whether for agricultural, residential, or commercial use, our dedication to innovation makes our lead-free pipes the trusted choice for modern water extraction.
Complete system accessories include top-bottom adaptor sets, pump guards, lowering jigs and belt spanners.
4. Enhanced Locking System Features
Shock-Absorbing Rubber Ring: Beyond the Double S.S. Stud Pin Lock System, our column pipes incorporate a specialised rubber ring at the coupler-pipe junction. This addition ensures 100% secure locking while absorbing shocks and impacts during transportation. It also reduces installation errors during lifting or lowering.
Permanent Authentication Stripe Pattern: A distinctive stripe pattern runs across the entire pipe wall thickness, created during the extrusion process (not printed or embossed). The stripe color corresponds to the pipe’s pressure class. This provides permanent identification that cannot fade or peel.
Advanced Jointing Technology: Pipes and couplers are joined using a proprietary special compound that creates permanent joints without affecting thread dimensional stability. This compound jointing process, combined with the mechanical locking system, ensures extended service life and reliable leak-proof performance.
Annealing for Superior Mechanical Properties: Every Astral column pipe undergoes a specialised annealing process during manufacturing. This heat treatment enhances the pipe’s mechanical properties, ensuring consistent performance under demanding operational conditions.
5. Comprehensive Quality Assurance
We treat every unit as a precision-engineered tool. To maintain the title of the best pipe for borewell systems, a multi-stage testing protocol is enforced:
In-Process Monitoring: CNC-calibrated thread gauge testing and continuous extrusion checks for dimensional accuracy.
Performance Verification: Post-assembly tests, including Ultimate Breaking Load (UBL) and high-pressure joint leakage inspections.
Full Traceability: Each coupler features batch-coded identification for complete quality-control tracking.
How to Install Column Pipe for Submersible Pump?
Below are the Installation Procedure of Column Pipe for Submersible Pump
1. Insert MS Flange
Insert one MS Flange onto the Bottom Adaptor from the bottom side.
2. Fix the Adaptor
Fix the Adaptor to the pump with a wrench, and support it tightly.
3. Wash with Washing Powder and Clean Water
Wash the male and female threads of the PVC Small Piece with washing powder, water and clean water. Insert into the Adaptor Square Threads.
4. Connect Flanges with SS Rods
Place the second MS Flange on top of the PVC Small Piece coupler and connect both flanges with SS rods. Drop the pump with pipes one after another, using a lowering jig/elevator with proper manpower support.
5. Insert Pipes
Clean the male and female threads with washing powder, water, and clean water. Insert pipes one by one until the last pipe is connected.
6. Fix Winding Wire
Tie the cable to the pipe’s outer walls loosely using winding wire, PVC sleeve or cotton thread. Leave an extra length of approximately one foot for each pipe to absorb vibration jerks.
7. Fix the Top Adaptor for Usage
Fix the Top Adaptor to the final pipe coupler. Adjust with the coupler and bend for regular usage.
Note: Maintain a minimum play between both flanges while tightening the bolts to the rods.
Essential Precautions and Maintenance of Borewell Pipes
- Seal Integrity: Always use new EPDM ‘O’ rings during reinstallation. Do not overtighten, as crushing the seal can lead to joint failure.
- System Protection: Install high-quality reflux valves to prevent water hammer and backspin. Use a safety rope (nylon or steel) as a secondary precaution against pump drops.
- Environmental Handling: In silt-heavy wells, flush the bore-well thoroughly before attempting to pull a stuck pump to avoid excessive tensile stress.
Handling and Storage
Proper care maintains pipe integrity before it ever reaches the ground. Handle pipes with care, as they are lighter than metal counterparts. Avoid dragging them across truck beds; use forklifts for pallets and handle with extra care in freezing conditions (below 0°C) to prevent impact damage.
Indoor storage is preferred to minimise UV exposure. If stacking, place the thickest-walled pipes at the bottom. Ensure racks provide continuous support or support at intervals no greater than three feet to prevent sagging, with a maximum stacking height of seven feet.
Following these guidelines ensures pipes remain in excellent condition during handling and storage.
