Modeling of underground hydrogen pipelines
Process Safety Progress, 2013Hydrogen is a critical component in the production of cleaner fuels. Underground pipelines provide a safe, reliable supply of hydrogen to refineries and the petroleum industry. Proper assessment of the risks associated with underground hydrogen pipelines requires an accurate model of the jet fire consequence.

Earthquake response of underground pipelines
Earthquake Engineering & Structural Dynamics, 1979AbstractSeismic response of underground pipelines is investigat́ed theoretically considering dynamic soil‐pipe interaction. A lumped mass model of the pipe is employed with the soil reactions derived from static and dynamic continuum theories. The soil is supposed to be homogeneous or composed of two different media separated by a vertical boundary ...

Design and Modeling of Pipeline Inspection Robot (PIR) for Underground Pipelines
2021The rapid growth of in-pipe inspection robots has been demanding in the society which is widely used in oil and gas industry, power plant industry, and sewage system, etc. This kind of robot can be applicable for inspecting the internal surfaces of underground pipelines like defects, cracks, and internal erosion.

Underground Pipeline Corrosion
Transportation Engineering Journal of ASCE, 1973It has been estimated that losses to the water works industry in the United States due to underground corrosion are in excess of $150,000,000 annually. Work definitions and theory of underground pipeline corrosion are presented. Various methods have been tried in an attempt to combat the effects of corrosion on ferrous metal pipe buried in the ground ...

Control of Corrosion in Underground Pipelines
Journal AWWA, 1954Stray current is found flowing in the earth as the result of the operation of both intentionally and unintentionally grounded d-c systems. The most common offenders are street railways and electric railroads. Frequently difficulties are also caused by manufacturing plants and other d-c power users. The operation of a d-c traction system illustrates the

Microscopic Study on the Corrosion of Underground Pipeline
Key Engineering Materials, 2016Corrosion on the water pipelines can potentially cause substantial human and economic losses. This paper concentrates on corrosion observation on the underground pipeline material as a part of our continuous study regarding this work. The samples which is mild steel taken from actually used pipeline at the site.

Unsteady heat losses of underground pipelines
Journal of Engineering Physics, 1977Analytic expressions are presented for the unsteady temperature distribution of the ground and heat losses of an underground pipeline for an arbitrary variation of the temperature of the medium being transferred and boundary conditions of the third kind at the pipe wall and the surface of the ground.

Corrosion and Protection of Underground Pipelines
ICPTT 2012, 2012With China's rapid development of the petrochemical industry and an improvement in city utilities (water, gas, and sewer services), underground pipelines are literally the "lifeline of city." However, corrosion can cause perforations that will eventually lead to leakage accidents creating an Underground Pipeline Hazard or “time bomb" when gas ...
