PVC-U Water Supply Pipe for irrigation
I.Pipe Introduction,
The PVC-U irrigation pipe (full name unplasticized poly (vinyl chloride) (PVC-U) pipe for low-pressure conveyance in irrigation) takes PVG resin as the main raw material, added with proper auxiliaries; it is manufactured and formed by mixing, extrusion, sizing, cutting and flaring processes. The pipe has large stiffness, high external force resistance, and it is not easy to be destroyed by external forces when being buried under ground for water delivery, and it will not rust. It does not have strict requirements for water quality; it is not easy to accumulate dirt or to be blocked.
