CRUMPLER'S corrugated plastic pipe and accessories meet and exceed all specifications concerning corrugated plastic pipe. These specifications include:

Both CPP Single Wall corrugated and CPP Dual Wall Smooth Core/n-10 corrugated meet the same AASHTO pipe standards cited above. The two styles are differentiated by the addition of the letter "C" or the letter "S" to the end of the appropriate spec. The "C" indicates a "corrugated interior wall", and the "S" indicates a "smooth core interior wall". Similarly, the letters "CP" indicate an interior corrugated wall that is perforated, and "SP" indicates a smooth core interior wall pipe with perforations. The AASHTO standard is based on the ASTM single wall standards cited above. CPP pipes can be made with up to 100% re-cycled HDPE content per the test criteria established in the above noted pipe standards, if requested. In addition to the generic ASTM and AASHTO specifications, specification writers can also cite CPPA-100 from the PPI/CPPA (Corrugated Polyethylene Pipe Association)
