Reliability and Durability of Pipelines

Dear Colleagues, 

Pipelines are extremely important for modern society because they are the medium for the transportation of water, wastewater, oil, and gas. A pipeline failure or rupture is likely to occur when the environmental and operational stresses act upon a pipe whose structural integrity has been compromised by corrosion, degration, inadequate installation, or manufacturing defects. Pipeline failure can be sudden and catastrophic, can impact the lives of hundreds or thousands of people, and can cost millions of dollars.

Pipeline failure is an environmental, safety, economic, and operational issue. These factors are the basis for the installation of pipelines and also have significant influence on the decision to renew pipelines. In selecting an appropriate trenchless pipeline renewal method, it is important to consider durability, reliability, load-carrying strength (hydrostatic and soil/traffic in addition to internal pressures), social impacts, constructability and bypassing requirements, pipe section lengths, and types of joints, as well as the suitability of a specific method and the availability of qualified contractors. The aim of the renewal selection process is to consider all factors to arrive at the most cost-effective and technically viable solution.

Globally, pipe renewal costs may reach more than trillions of dollars in the coming decade; therefore, there is a need to determine a suitable material that maximizes both the durability and reliability of pipelines. Overall, corrosion resistance, hydraulic efficiency, flexibility, abrasion resistance, toughness, fused joints, and long service life are among the important factors for determining the durability and reliability of pipelines. Proper design, specifications, installation, and operation typically mitigate any reduction in durability and reliability due to the aforementioned issues.

Because all pipeline projects impact the environment and society, the goal of a pipeline design is generally to choose durable products that perform as intended, that have an acceptable cost, that avoid adverse environmental impact, and that satisfy societal needs, both in the short and the long term. Sustainable products provide performance and quality levels equivalent to their less-sustainable alternatives while minimizing any adverse environmental and societal impacts. The reliability and durability of pipelines can also help field engineers and utility owners in understanding the best structural analysis methods and in more accurately predicting the life of their pipeline assets.

This Special Issue calls for state-of-the-art research and practices focusing on different aspects of the renewal of buried pipes, utility conduits, and culverts, using trenchless technologies to gain further insights into the reliability and durability issues of pipelines. Reviews on the research and practices of this field are also considered within the scope of this Special Issue.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Infrastructures is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
