This specification covers the general requirements of corrugated High Density Polyethylene (HDPE) drainage tubing for use in various land drainage applications.
Pipe shall be manufactured from high density polyethylene resin, which shall meet or exceed the requirements of cell classification 424420C as defined in ASTM D3350. Resistant to a wide range of soil acidity: pH 1.25 to 14.
The pipe shall be joined with snap, insert or split couplers.
Drainage tubing shall have minimum pipe stiffness of 210 kPa at 5% deflection when tested in accordance when tested in accordance with ASTM D2412.
The following Manning's 'n' values shall be used to calculate flow. See CPPA Technical Hydraulic booklet available from Ideal Pipe or the Plastics Pipe Institute.
Structural design shall conform to the industry accepted procedures found in the Corrugated Polyethylene Pipe Association's technical booklets from Ideal Pipe or the Plastics Pipe Institute.
Ideal drainage tubing is available with a variety of perforation patterns and engineered geosynthetic filters for different soil types.
Ideal drainage tubing is available in diameters from 50 mm (2") to 375 mm (15") and shipped in selective coil sizes, 50 ft. to 4000 ft. or length sections of 20 ft. Nominal pipe size is based on inside diameter of the pipe. See below:
