Easy Thread, Large Diameter HDPE pipe
Weholite threaded pipe is a large diameter, structural profile wall pipe made from advanced, high density polyethylene (HDPE) resin, manufactured to ASTM F-894. Designed for gravity, Weholite's raw material properties have been combined with a patented structural design technology, creating a strong, robust, lightweight pipe with superior performance and loading capacity.
Weholite pipe is much easier to handle and install than heavier, rigid concrete pipe, allowing for cost savings in transportation, installation and overall construction costs.
