Landfill Applications:
HDPE pipe provides excellent characteristics for a variety of landfill applications including methane gas recovery, leachate collection, dual containment piping, and manholes. The flexible nature of HDPE pipe provides an excellent pipe material for an environment that is constantly moving and settling. HDPE pipe is also noncorrosive and provides a pipe material that will be inert to the landfill environment. HDPE pipe is manufactured to 63" sizes. The company has the ability to perforate pipe through 12". We offer three different dual containment systems with a complete line of dual wall fittings.
Perforated Pipe:
Perforations are available 3" through 12" IPS. Hole sizes can vary from 1/4" through 3/4" diameter. Spacing ranges from 2" through 24" centers which can be staggered upon request.
The following patterns are available:
- Style - A 4 rows 60 degs. from top and bottom
- Style - B 3 rows 120 degs. apart equal spacing
- Style - C 2 rows 180 degs. apart
- Style - D 3 rows 90 degs. apart
- Style - E 2 rows 120 degs. apart
- Style - F 4 rows 90 degs. apart
Dual Wall Containment:
Dual containment HDPE pipe systems can be broadly characterized in three categories. The first is a proprietary product called simutaneously fused DC pipe. The second system requires electrofusion or an anular heating iron. The third system uses a sliplined conductor pipe inside the containment pipe.
System 1: simultaneously fused system which utilizes standard fusion procedures. Size capabilities range from 2" through 18" for the carrier pipe.
System 2: utilizes standard fusion procedures on the carrier pipe and an anular heating iron or electrofusion coupling on the containment pipe. HDPE Pipe and fitting systems are available from 2" through 8".
System 3: the containment is installed first, then the conductor pipe is slip lined inside the containment pipe. The carrier pipe is not restrained and is not centered in the containment pipe. This system is usually best suited for smaller pipe sizes, where long coils are available, and in circumstances requiring no restraint.
