Molecularly oriented polyvinyl chloride pipe (PVCO) was developed in Europe in the 1970’s but was not commercialized in North America until the early 1990’s. This paper briefly examines the current state of the North American oriented pipe market and discusses molecular orientation and its effects.

Finally, comparisons are made among pipes made from PVCO and three other pipe materials : PVC, ductile iron, and HDPE.
