Pipe and Soil Mechanics for Buried Corrugated HDPE Pipe

Pipeline Engineering and Construction, 2004
High density polyethylene (HDPE) pipes are being installed as buried conduits at an increasing rate. HDPE pipes are lightweight and resistant to corrosion and abrasion. Because HDPE pipes are flexible, the soil embedment is a major component of the conduit.

Corrugated pipe as beam energy stabilizer

High Power Laser and Particle Beams, 2014
Stringent tolerance budget is restricted on the linear accelerator (linac) parameters, such as the mean beam energy stability, peak current variation, electron bunch arrival time jitter, and the transverse beam position offset, in order to generate stable output pulses in modern linac driven free electron laser facility.

Instabilities of flow in a corrugated pipe

2009
Flow in a corrugated pipe is considered. Different from previous studies, both the corrugation amplitude and wavelength are much smaller than the pipe diameter. Results of the multi-scale analysis show that the mean flow modulated by the surface corrugation becomes unstable to three-dimensional travelling waves at moderate Reynolds numbers, and the ...

Hydraulic Roughness of Corrugated Pipes

Journal of the Hydraulics Division, 1962
Original data on friction losses in two types of corrugated-metal pipes, obtained in the course of investigations into the hydraulic behavior of corrugated-metal culverts, are reported. A comprehensive friction factor-Reynold's number diagram, incorporating all published data on corrugated-metal pipes, is presented and used to develop a relationship ...

Flow establishment in helical corrugated pipe

Canadian Journal of Civil Engineering, 1988
Corrugated steel pipe suppliers have recently switched from annular rivetted corrugated pipe to helical lock seam corrugated pipe. This was done as a manufacturing expedient, but there has been an unexpected benefit in terms of reduced hydraulic resistance.

Performance of Corrugated Polyethylene Entrance Pipe

1989
Observations noted during inspections of 57 entrance pipe installations are summarized. Inspections were conducted in 1986 and 1989. It is recommended that corrugated polyethylene pipe be permitted routinely as an alternate to other materials for entrance pipe.
