This paper presents a technology for locating plastic pipe buried underground. The technology was developed for the water market in India and, through intra-company collaboration, has been introduced to the water and gas markets in the United States. Information regarding product technology and end-use considerations is presented.
This paper presents the technology for a unique locatable pipe solution and history of its development in India along with the collaboration within a global company structure to launch this technology into US markets.
This fully locatable polyethylene pipe solution which provides precise traceability of the underground networks and also offers helpful features like depth measurement and GPS coordinates. It carries a co-extruded highly conductive copper wire encased in a high density polyethylene web along the entire length of the pipe. The co-extruded web is designed to provide excellent adhesion to the pipe and protection to the tracer wire to withstand the rigors of underground installation. This wire carries a signal from a battery operated transmitter that is easily sensed and received by a hand held locator. The exact depth and location of the buried pipe is displayed on the receiver to provide exact geographical coordinates.
This locatable pipe technology was developed in India where it is widely accepted in that region for open-cut installations. Global collaboration of inter-company teams and the sharing of best practices and product innovation have led to the introduction of this product into the US markets where pipe location and tracking is in high demand. Case studies are presented on the successful use of this product in India and Oman for opencut installations. Case studies are also presented detailing a variety of trial installations performed with the City of Arlington, TX as part of the market introduction of this product into US markets. These case studies include a variety of installation methods including open-cut, horizontal directional drilling and pipe bursting.

HDPE Pipe holds a dominant position in several markets in North America: natural gas distribution, oil patch, mining, landfill and geothermal. So why are polyethylene’s municipal water and wastewater market shares so much lower than these other industries? How has the polyethylene industry been successful in growing...

PP-R (random copolymerized polypropylene) has been widely used in hot and cold water systems. However, the standard PP-R pipes have the disadvantages of a large high-temperature thermal expansion coefficient, an insufficient notched impact strength, and a low temperature and pressure resistance. In this paper, a new...

HDPE pipe can be relatively easily scratched during the manipulation on the site, which is especially true for the marine pipelines. Installing the scratched marine pipe with the S bend method presents a risk and repair methods are usually performed. Currently, there is no standard defining the repair procedure, in...

For controlled water disinfection, typically chlorine is used and preliminary studies demonstrate its aging and crack growth acceleration effects on polyolefin pipe materials [1, 2]. Although the use of recycled plastics is not prohibited in some ISO standards for polyolefin piping systems [3–5], only small amounts...

For PE 100-RC, two tests are still under development for pipes: the point load test (PLT) and the accelerated notch pipe test (aNPT). The PLT was developed by a project group consisting of manufacturers and end users. The PLT determines the resistance to point loads as they can occur in practice. An earlier study...

The Point Load Test (PLT) [ 1, 2] was designed to simulate the SCG (slow crack growth) failure initiated by a rock pressing into the exterior wall of a polymer pipe. Today’s PE materials sustain long PLT testing times, due to its high SCG resistance design. Consequently, an accelerated “PLT+” with the support of...

Flowable fill is used for many applications, but mainly for pipe trench embedment and backfill. There are three ways that using flowable fill can be kind to the environment. Because flowable fill is self-leveling and has a strength greater than the native soil, the trench cross section can be minimized. This means...

For pipe applications, catastrophic failure due to crack growth has to be prevented by all means. Techniques to develop new and even tougher pipe materials are explored in this contribution. The aim is to create a multi-layer architecture, that exhibits high toughness as well as damage tolerance towards sharp notches....
