What is a Rain Hose Pipe?
A rain hose pipe has small openings on the entire length, which releases sprays of water to crops.
A rain hose pipe connects to the water source on one end and is laid on the plant line.
Specifications of a Rain Hose Pipe
- Available in diameter sizes of 32mm, 40mm and 50mm.
- Made of UV treated and non-corrosive PE material.
- Emitter hole size ranges from 0.5mm -1 mm.
- Spray radius of 1.5-6 m depending on diameter size
- Roll length 1000 m/acre
Where to apply Rain Hose Irrigation System
This method of irrigation is often used in areas where there is limited access to water, as it allows farmers to efficiently distribute the water, they have available for their crops. It can be applicable in slightly hilly or gently sloping regions where drip or furrow irrigation are not practical.
How Rain Hose Pipes work
Rain hose pipes work under high pressure to enhance continuous spray jets of water from emitter holes. It requires a pressure of 0.8-1.5 bar for it to operate.
When water is flows the rain pipe releases water in thin spray jets from its numerous small holes. The sprays wet the ground faster and can reach a height of 2 m and a spray radius of up to 6 m depending on the diameter of the rain hose pipe.
Requirements for a Rain Hose System
- PVC mainline pipe
- Rain Hose Tape
- Connector
- End cap
