Many of today's plastics were developed during and just before world war II. Some were introduced into piping systems in the 1930's. In the United States, plastic piping systems obtained wide acceptance in the late 1950's and early 1960's. Since then plastic pipe usage has increased at an astounding rate.
Water mains, hot and cold water distribution, drain waste and vent (DWV), sewer, gas distribution, irrigation, conduit, fire sprinkler and process piping are the major markets for plastic piping systems throughout the world. Underground piping makes up the largest part of the market.
The primary plumbing applications in which plastic piping is used:
- Building Drain, Waste and Vent (DWV)
- Building Sewers and Drains
- Water Service
- Hot and Cold Water Distribution
Some other applications:
- Fire Sprinkler Piping
- Swimming Pool Piping
