Metal pipes have been used and installed in fluid and gas applications since the mid-19^th century. Metal pipes are strong, safe, and provide excellent performance for many demanding services. Plastic pipes are an alternative to metal pipes for many fluid applications.

They do not have the same high-pressure ratings, but they are highly corrosion resistant. They do not rust, scale, pit or corrode. They are lightweight and easy-to-install, which make them an excellent choice for many liquid applications. Over the decades, users have learned that a plastic piping system, when properly selected and installed, will require very little maintenance and will offer many years of uniform service. Since thermoplastic piping is an ideal choice to transport fluids, how would plastic piping perform with compressed air? This article will focus on the suitability of plastic pipe systems as well as joining methodology in compressed air applications.
