To ensure our customers benefit from the most current technology in plastic pipe manufacturing, as well as products that meet the most rigorous certification standards, Flying W Plastics maintains membership with the following industry associations:

Flying W Plastics is a member in good standing with the Plastics Pipe Institute (PPI). PPI is the major trade association representing all segments of the plastics piping industry. As an association, PPI focuses collaborative efforts to accumulate data, concentrate facts and target resources toward advancements in plastics piping application and usage. PPI promotes contemporary use of plastics piping for water and gas distribution, sewer and wastewater, oil and gas production, industrial and mining uses, power and communications, and ducting and irrigation.


PPI’s vision and leadership have resulted in the establishment of uniform testing and design criteria that have become the foundation for all current applications of plastics piping. As PPI members, Flying W Plastics recommends PPI’s Handbook of Polyethylene Pipe, Second Edition for testing and design criteria of all HDPE pipe manufactured by Flying W Plastics. This handbook is available for purchase online. The individual chapters can be downloaded free of charge. Many case studies, technical bulletins, and pipe calculations can also be found at the PPI web site.
