If you’re planning an irrigation system, a water supply line, or a tube well installation in Nepal, choosing the right HDPE Pipe size and pressure class matters as much as choosing a reliable manufacturer. Here’s what to know before you buy.
Understanding HDPE Pipe Sizes
HDPE Pipe in Nepal is typically sold by outer diameter (OD), ranging from small 16mm pipe used for drip irrigation up to large 315mm pipe used for municipal water supply and industrial applications. Kamla Polythene, a BN Mahto Group company based in Janakpur, manufactures across this entire range — 16mm to 315mm — using PE-100 grade granules to NS-40 Nepal standard.
Choosing the Right Pressure Class
HDPE Pipe pressure classes (PN6, PN10, PN12.5, PN16) indicate how much internal water pressure the pipe can safely handle. Lowerpressure classes like PN6 suit gravity-fed irrigation, while PN10–PN16 are typically used for pumped water supply systems and river water intake lines where pressure is higher.
Common Uses of HDPE Pipe in Nepal
- Agricultural irrigation: Drip and sprinkler systems, especially given Nepal’s dependence on agriculture across the plains and hill regions
- Tube wells and bore wells: Corrosion resistance makes HDPE Pipe ideal for groundwater extraction
- Municipal water supply: Larger-diameter pipe for town and city distribution networks
- Sewerage and effluent disposal: Chemical resistance handles industrial and municipal waste transport
- Cable ducting: Protecting underground electrical and telecom cabling
Why HDPE Pipe Outperforms Traditional Pipe in Nepal’s Climate
Nepal’s geography spans plains, hills, and mountains, with temperature swings and ground movement that can crack rigid pipe materials over time. HDPE Pipe remains flexible from -60°C to 60°C and resists cracking under seasonal ground shift — a key reason it has become the preferred piping material over steel or cement pipe for many contractors and government irrigation projects.
Buying HDPE Pipe in Nepal
When sourcing HDPE Pipe, check that the manufacturer certifies to NS-40 standard and uses PE-100 grade virgin granules rather than recycled material, which affects long-term durability. Kamla Polythene and Plastic Industries Pvt. Ltd, based in Janakpur, has manufactured to these standards since 1987.
