What is the most commonly used plastic pipe material?

The most commonly used plastic pipe material is PVC (Polyvinyl Chloride). PVC is widely used in various plumbing applications due to its excellent properties, including durability, resistance to corrosion and chemicals, and affordability. PVC pipes are lightweight, easy to install, and can be used for both residential and commercial applications, making them a preferred choice among pipefitters and builders.

Furthermore, PVC has a long history of use in the industry, which has contributed to its availability and the establishment of comprehensive standards for its application. This widespread acceptance and reliability ensure that PVC maintains its status as the go-to material when it comes to plastic piping solutions.

Other materials, such as HDPE (High-Density Polyethylene), PPR (Polypropylene Random), and CPVC (Chlorinated Polyvinyl Chloride), have their specific use cases and benefits but do not match the overall usage and versatility of PVC in the realm of plumbing and piping systems.
