EX Pipe is produced from a base of PVC, conforming to ASTM D-1784 cell classification 12334-B, tested to ASTM F 1504-Standard Specifications for folded Poly Vinyl Chloride (PVC) Pipe for existing sewer and conduit rehabilitation. The PVC material is specifically designed to meet the stringent requirements of the EX Method of pipeline reconstruction. The high strength EX Pipe delivers chemical, earthquake and abrasion resistance, which results in a superior pipeline with long-term, proven stability.With an extremely smooth material surface and only minimal reduction of pipe diameter, the new EX Pipe meets or exceeds the flow capacity of the original pipe, while forming a new, exceedingly strong and corrosion-resistant pipe-within-a-pipe. The EX Pipe can be installed in lines with bends up to 90° and small diameters changes with minimal or no wrinkles.
