Use on long, steep slopes when there is a high potential of flow concentration or rill development. Design and Installation Effective use of temporary slope drains involves design of an effective collection system to direct flows to the pipe, proper sizing and
HDPE is used to manufacture geomeranes, geocellular webs, pipes, etc. ESC was first identified as a problem in HDPE in the 1970’s in gas pipes, and then in HDPE geomeranes in the 1980’s. Since then, the problem has been researched and is now fully understood such that ESC can be avoided.

On the steep slopes of Mercer Island we investigated a landslide that reached just below the basement footings of a large two-story residential home. During our site subsurface investigation we provided our client with several potential remedial options along with the relative risks implied by each.
30/10/2006· For anchoring the steep part, you may be able to use a Manta Ray or duckbill type device attached to a collar around the pipe. HDPE pipe design must accomodate expansion/contraction of the HDPE. I had a tightline project where the change in length was about 3 feet from summer to winter; slip connections consisting of one pipe sleeved inside a slightly larger pipe are typically used.
Irrigation Systems found that the HDPE pipe was a good solution to the challenges of transporting materials to a road-less jobsite, and the chilling temperatures that were as low as 14F (-10C) during installation. Steep mountain slopes made installation of the
placement, among others. With regards to construction of these facilities with very steep slopes, this paper Puhui Pipe manufacturer in China diameter dual wall HDPE pipe can speed up the placement of the material in areas Puhui Pipe manufacturer in China
This self-study course provides training on the design and analysis of buried High Density Polyethylene (HDPE) Pipe in accordance with the ASME Boiler and Pressure Vessel Code Case N-755. The course covers all aspects of the design of buried HDPE Pipe including pressure design, soil loadings, thermal expansion loads, and seismic design requirements.
