application
Drink water pipelines are the backbone of municipal and regional water supply systems.
Municipal Water Transmission & Distribution: Primary transmission mains carrying treated water from plants to reservoirs/towers, and secondary distribution networks delivering water to homes, businesses, and institutions.
Water Treatment Plant Internal Piping: Connecting processes within treatment plants (clarifiers, filters, disinfection contact tanks, pump stations).
Reservoir and Elevated Tank Inlet/Outlet Pipes: Connecting storage facilities to the distribution grid.
Large Building & Campus Water Supply: Dedicated mains for hospitals, universities, industrial complexes, and high-rise buildings.
Rural Water Schemes: Extending safe drinking water to remote communities and agricultural areas.
Infrastructure Projects: Dedicated pipelines for new developments, urban expansions, and disaster recovery projects.
advantages
Water Quality Protection: Certified linings and materials prevent corrosion, leaching of contaminants, and biofilm growth, ensuring water remains safe and aesthetically pleasing (no taste/odour issues).
Hydraulic Efficiency: Smooth internal linings (e.g., CML, PE) minimize friction losses, reducing pumping energy costs over the pipeline’s lifetime.
Durability & Longevity: Resistant to internal corrosion and external environmental factors (soil corrosion, UV for plastics), designed for service lives exceeding 50 years with minimal maintenance.
Leak Resistance: Robust materials and reliable jointing systems (e.g., push-fit joints with elastomeric seals, welded joints) significantly reduce water loss.
Structural Integrity: High strength-to-weight ratio (especially DI, GRP) withstands earth loads, traffic loads, and internal pressure surges.
Versatility: Available in a wide range of diameters (DN80-DN3000+) and pressure ratings (PN6-PN32+) to suit any project requirement. Suitable for diverse installation methods (trenching, trenchless – HDD, microtunneling).
Cost-Effectiveness: Low lifetime cost due to minimal leakage, reduced pumping costs, long service life, and low maintenance requirements.
packing
Packaging focuses on preventing damage to linings/coatings and pipe ends during transport and handling. Common methods include.
Bundling: Smaller diameter pipes (DI, plastic) bundled with protective strapping and end caps.
Cradling/Saddling: Larger diameter pipes (steel, DI) transported on flatbed trailers or ships using timber or custom cradles to prevent deformation. Ends are always protected with caps or covers.
Container Shipping: Suitable for smaller diameter and shorter length pipes
Break Bulk Shipping: Used for large quantities of pipes, requiring careful stowage and securing on vessels. End protection is critical.
Specialized Trailers: For oversized pipes.
Transportation modes include road, rail, and sea. Emphasis is placed on using clean transport and ensuring no contamination of the pipe interior.
