External pressure induced buckling collapse of high density polyethylene (HDPE) liners: FEM modeling and predictions
(Elsevier, 2015-08)
Abstract Thermoplastic polymers such as HDPE are nowadays widely used as lining materials for oil and gas pipelines. However, during maintenance or unexpected service stoppages, these liners can undergo external pressure ...
Buckling collapse of HDPE liners: Experimental set-up and FEM simulations
(Elsevier, 2016-09)
The purpose of this work is to provide a more complete framework for the development of short-term thermoplastic models to improve the design of liners subjected to external pressure. A device to perform short-term physical ...
A personal view oil pipeline relining with hdpe: Experimental and calculation challenge
(Budapest University of Technology and Economics, 2018-07)
Nowadays the use of polymers in the gas and oil transportation industry is widely spread. One of their main uses is as lining materials for oil pipe - lines. The liners consist of a free-standing thermoplastic pipe that ...
Numerical tool to model collapse of polymeric liners in pipelines
(Pergamon-Elsevier Science Ltd, 2012-03)
Polymeric liners are widely used in the gas and oil transportation industry. They provide improved corrosion resistance to metallic tubes and they also are used in rehabilitation of deteriorated pipelines. Oil derived gases ...

Determinación del revestimiento del Tunnel Liner mediante el modelamiento geotécnico aplicando el método de Elementos Finitos, en el Distrito de La Perla Callao
(Universidad Peruana UniónPE, 2019-12-18)
A través de esta investigación se busca mostrar la realidad del diseño de túneles en zonas urbanas, donde muchas veces no se tiene en cuenta la interacción suelo – estructura, dejando de lado los asentamientos que estas ...
Assessment of the interface shear strength between HDPE geomembrane and tropical soil by the direct shear test
(2018-01-01)
Liners are important impermeable constituents of sanitary landfill to contain the transport of pollutants to the unsaturated zone. The system can be made of different kind, being the compacted soil and geosynthetics widely ...
UV exposure of polymeric geomembranes
(Zhejiang Univ Press, 2008-01-01)
The break of polymer chemical bonds may occur due to penetration of sun short wavelengths. In sanitary landfills for instance, ultraviolet radiation affects uncovered materials and can be dangerous during the installation ...
