Abstract: This paper presents an experimental investigation into the axial pullout behavior of buried medium-density polyethylene (MDPE) pipes under various pulling rates. Tests were conducted in a facility developed at the Memorial ...

Abstract: The maximum axial force on a pipeline subjected to axial ground movement is commonly calculated using a design equation developed without proper consideration of soil-pipe interaction. The authors’ recent work revealed ...

Abstract: Medium-density polyethylene (MDPE) pipes are widely used for gas transmission and distribution systems. The behavior of the pipes buried in the ground is governed by soil–pipe interaction. MDPE possesses a time-dependent ...

Abstract: Buried medium-density polyethylene pipes are conveniently used in gas distribution systems, particularly in areas subjected to ground movements, due to their flexible property to accommodate large deformation. The pipelines ...

Abstract: The steel pipelines used for oil and gas transportation are subjected to corrosion during the service life, which reduces the strength of the pipelines. The maximum operating pressure of a corroded pipeline depends on the ...

Abstract: Medium-density polyethylene (MDPE) pipes are extensively used for gas distribution systems in Canada and worldwide. MDPE pipe material possesses time-dependent mechanical properties that govern the performance of the pipes ...

Abstract: Circumferential cracking or ring fracture has been identified as the most common type of failure mode for cast-iron water mains. However, the cause of circumferential cracking in water mains is not well understood. A number ...

Abstract: The vulnerability of water distribution networks (WDNs) to water-main breaks is used for prioritizing pipes in the network for maintenance planning. In this paper, a parameter of graph theory, algebraic connectivity (AC), ...

Abstract: Small-diameter steel pipes are often used for the distribution of gas to residential homes. These pipelines must service the end-user, even in landslide-prone areas, necessitating the study of their response to ground ...
