PVC-O, known in Chinese as biaxially oriented polyvinyl chloride, represents the latest evolutionary form of PVC piping. This pipe material is manufactured through a specialized orientation processing technique that involves axially and radially stretching PVC-U pipes produced via extrusion. As a result, the long-chain PVC molecules within the pipe are arranged in an orderly, biaxially oriented manner, yielding a new type of PVC pipe with high strength, high toughness, excellent impact resistance, and superior fatigue resistance.

Drip irrigation tape uses plastic tubing (drip irrigation pipes) to deliver water directly to the root zones of crops through openings or drippers along a 10mm-diameter emitter line.

Introduction to PVC Pipe Products Polyvinyl chloride pipes (commonly referred to as PVC pipes in English) are plastic pipes that were among the earliest to be developed and put into practical use. They are produced by heating and extruding a mixture of polyvinyl chloride resin combined with auxiliary materials such as stabilizers, lubricants, and color masterbatches.

I. Introduction to PVC Pipe Products Polyvinyl chloride pipes (commonly referred to as PVC pipes in English) are plastic pipes that were among the earliest to be developed and applied. They are produced by heating and extruding a mixture of polyvinyl chloride resin combined with auxiliary materials such as stabilizers, lubricants, and color masterbatches. After years of accumulated experience in processing and application, PVC pipes have now established standardized production and processing techniques as well as a comprehensive supporting infrastructure. Coupled with their economic, environmentally friendly, and cost-effective advantages, PVC pipes have become the dominant product in the rubber and plastic piping industry.
