The PPI provides plastics piping standards for multiple applications.
The Plastics Pipe Institute Inc. (PPI) publishes standards for the design, manufacture and use of polyethylene pipe in a variety of applications.
PPI standards promote the use of plastics piping for water and gas distribution, sewer and wastewater, oil and gas production, industrial and mining uses, power and communications, duct and irrigation.
PPI’s standards are the foundation for all current applications of plastics piping. In addition, PPI creates standards for the methodology of rating long term material strength and preferred numbers to state specific properties. PPI also engineered the first code of acceptance for plumbing, industrial, commercial and gas distribution.
