Polyvinyl chloride, more commonly known as PVC, is a versatile thermoplastic polymer that can be molded into different shapes. It was first created in the 1870s but did not become widely used in piping applications until the late 1950s. When PVC is mixed with plasticizers, it becomes pliable and durable, making it well-suited for piping uses both indoors and outdoors.

Physical Properties of PVC Pipe

PVC Pipes is lightweight yet tough, resisting impact and pressure. It has a smooth internal surface that causes little friction loss for liquids flowing through the pipes. PVC is highly resistant to chemicals found in water, soil or sewage systems, maintaining its integrity when exposed to salts, acids, alkalis and organic materials. It does not rust, corrode or decay over time like metal pipes. PVC is also non-conductive, preventing electrochemistry problems in corrosive environments. Thermosetting during manufacturing gives PVC pipe dimensional stability to maintain its shape.

Durability and Longevity of PVC Systems

Properly installed PVC Pipes systems can last 50 years or longer with little maintenance required. The materials are very stable and do not degrade over decades of use like other plastics may. PVC retains its physical properties in extreme temperatures from freezing to above boiling, making it suitable for both hot and cold water applications indoors or outdoors. It withstands freeze/thaw cycles without bursting. PVC is also resistant to root intrusion so underground pipes do not become clogged over the years. Overall, the longevity and low lifetime costs of PVC piping make it a wise investment.
