PRODUCTS AND SERVICE
Pressure Compensated drip tapes
Advantages:
The internal structure of dripper adopts elastic diaphragm to regulate pressure and control flow; 
The lifetime is effectively lengthened by injecting molded silicone membrane; 
The special designed flow path can effectively improve self-cleaning and anti-clogging capacity;
Anti-UV materials are suitable for all kinds of weather conditions; 
High mechanical strength, corrosion resistance; 
Ensure the uniform, precise and consistent irrigation, in the range of compensated pressure.

Feature: 
Can be Laid on the ground or buried; 
Different flowrate Can choose from;
Suitable for different terrain and slope of irrigation area.

pressure: 50-450 kpa
