What should the water belt of winter irrigation pay attention to when used?

Farmers should pay attention to these when they are choosing:
1.We as consumers won’t produce agricultural water hoses, the specific parameters of pipe may not be very understanding, but touch the pipe when the pipe with the skin surface is smooth, no broken diameter, diameter jump problem that we are easy to distinguish;
2.Again we need to have a look at the inside coating of agricultural water hose should be smooth, without defects such as wrinkle, rough, if the pipe has the above defects may cause irrigation pipe to use process to take off the layer tube;
3.The working pressure of the water hose should meet the requirements of the normal use of the hose, and the pressure is not enough to cause the removal and leakage in the user process.
4. Cold weather in winter requires high temperature resistance of water belt. It can be utilized without fracture at -20 low temperature, and the water belt is not deformed in the process.
