Polyvinyl chloride (PVC) and high-density polyethylene (HDPE) are two of the most common types of plastic pipes. A U.S. Trenchless Technology survey even showed PVC and HDPE as the top two choices by sewer system operators and engineers in most piping categories.
PVC and HDPE are used in a wide range of applications. PVC is used in plumbing and drinking water supply lines, above-ground and below-ground drainage, ventilation and exhaust systems, and electrical cable insulation.
HDPE pipes have long been used in gas, oil, and mining operations. They can transport potable water, wastewater, chemicals, slurries, compressed gases, and hazardous wastes. They are also used in firefighting, drainage, and ducting applications.
