Pipelines through embankments should be designed to withstand extreme weather-related events and everyday stressors. As extreme weather-related events are on the rise because of climate change, it is important to ensure proper design, construction, and inspection practices are understood and executed. This paper discusses common stressors that act on pipelines through embankments such as internal and external hydrostatic pressure, seepage, scour, Ph, and backfill movement; and provides suggested design, construction, and inspection practices that limit the impacts of extreme events and everyday stressors on pipelines. Suggested practices discussed in this paper include identifying hydrostatic forces, backfill selection and placement, proper pipe and joint selection, inspection practices during and after installation, and use of geotextiles.
The author’s goal is to aid designers, contractors, and inspectors to understand stressors that degrade pipelines and strategies to improve the durability of pipelines through embankments.

One solution in development for managing runoff water is the buried stormwater drainage retention tank or “crate”. The crate is typically a rectangular box structure made of thermoplastic components (flat panels and columns) assembled in a modular form. The function of the top panel is to transfer the load to the...

The European Commission set demandingly high recycling targets which will, when followed, eventually create an increased supply of polypropylene (PP) post-consumer recyclates (PCRs). No regulations currently mandate the use of recycled PP (rPP), so the industry is challenged to explore possibilities to utilize these...

A majority of field failure of viscoelastic plastic pipes can be attributed to slow crack growth (SCG) and has become crucial in terms of characterization of newly developed materials – particularly, if they are designed for pressurized pipe applications. In this study, investigations in terms of SCG resistances...

The strain hardening test (SHT, ISO 18488 [1]) becomes increasingly important for the characterization of high-density polyethylene (HDPE) grades and pipes made thereof. With regard to small pipe diameters, a smaller test specimen than the one defined in ISO 18488 has been developed. SHT results were demonstrated to...

For high pressure pipes above maximum operation pressure of 10 bar, this paper emphasizes PA-U12 as the easy to install alternative to steel. It underlines the superb performance of PA-U12 pipes for alternative installation techniques without need for a separate mechanical protection. An unplasticized polyamide 12...

We investigated the possibility of using a greaseless polyethylene (PE) ball valve by applying a coating on it to improve the valve’s robustness. In order to verify the valve’s operability, we performed initial-operating-torque, abrasion, and dust tests on both grease-applied and coatingapplied ball valves. These...
