Abstract:

Pipelines transport water, storm run-off, process wastes, petroleum, natural gas, slurries, solids, sewage, steam and other fluids either by gravity or under pressure. Pipelines are also used as utility corridors. The loadings on these pipelines vary considerably depending on the intended use. Soils, differential movement, seismicity, frost, temperature changes, pressure, vacuum, transients, construction, handling and shipping, are all usually considered, in addition to vibrations, blasting, bends, restraints, weak native soils, wave, self-weight, impact and live loads. The materials used by engineers and specification writers for pipeline construction could be broadly classified into metals, plastics, concrete, clay and composites. The last 20 years have seen numerous developments in pipeline materials, design procedures and standards in Europe and North America. Materials technology has evolved the most among all aspects of pipeline engineering in the last 20 years. Many new products appeared on the market and an equal number of products and trade names disappeared.
