Quality Assurance in Every Product

At PolyPipe^® , quality throughout the manufacturing process is an inherent value that assures the highest performance. Our manufacturing facilities start with only superior grade, polyethylene resins that have been specifically formulated for long-term integrity and performance in gas distribution systems.

Computer controlled extrusion techniques are utilized in the manufacture of our pipe to ensure quality. In addition, continuous wall monitoring during manufacture results in dimensional consistency.
