Poly pipes or irrigation pipe is made of black polyethylene. The wall of this pipe is thin to allow for easy joining and fitting of drippers and sprayers. As a general rule, 13mm pipe can be used for drippers, but 19mm will feed more emitters. Sprayers need 19mm pipe, and pop-ups usually require 19mm or 25mm depending on water pressure.

Flat Dripper Inlaid Drip Irrigation Pipe (Belt) is a new generation of water-conservation drip irrigation product developed from the cylinder dripper irrigation pipe. It is an economic water-conservation product, adapting to the developing requirement of the precise agriculture.
1. Advantages:
Mould the dripper for one time;
The dripper with its filtering window, has the new style wide and long flow channel；
The dripper has spacious area for filtering and wide size of flow channel section, so the blocking resistance is strong；
The water is turbulently flowing, and the deviation of the effluent evenness degree is below 5%；
The dripper is directly welded inside the pipe, so the pressure lose is slight and irrigation precision is high;
Compared with the field irrigation by flooding, water is saved by 30-40％，and output & efficiency is increased by 20-40％.
2. Basic characteristics：
The different wall thicknesses are suitable for the different ages and environments touse；
The different flow-rates and dripper intervals are suitable for the different water demand quantities of crops;It is convenient to install, transport and use；
The price of project is low, and the water-saving efficiency is high.
3. Working pressure: 40~120kpa
4. Suitable scope：field crops sowed in rows, big greenhouse, fruit trees, grape crops.
