PVC lay flat hose is widely used in agricultural irrigation because of its light weight, good flexibility, bright color, smooth coating, easy to roll, easy to move, high pressure resistance, corrosion resistance, wear resistance and aging resistance. However, in order to prolong the service life of PVC lay flat hose effectively, we should pay attention to its folding. First, after winding and drying, the new folding line can be fixed. According to this method, the service life of PVC lay flat hose can be greatly prolonged by any type of PVC lay flat hose. 2. Straighten the new PVC lay flat hose seam by folding it, and then irrigate it to make it slightly harder to fold the new seam. 3. Each section of PVC lay flat hose is folded by two persons at the same time. One person begins to fold the suture from any end point with his hand, and the other person follows and coils with the new folded thread. Therefore, when you use the PVC lay flat hose, you must be patient to fold it. This can not only facilitate the next use of the PVC lay flat hose, but also recycle and reduce costs.
