Arctic pipelines

are trunklines (gas and oil products pipelines) constructed within the Southern Polar Circle. The pipelines division into Arctic and those which are to the south of the Polar Circle is notional. Main characteristics of Arctic pipelines are determined by the specific climate conditions of a given territory: low radiation balance, summer average zero temperature and annual average subzero temperature, large areas of permafrost, wet lands and plenty of swamps in plains.
Arctic pipelines are constructed on pile supports. In the process of Arctic pipelines construction, axial strain compensation devices are installed; measures are taken to prevent pipes vibration caused by winds.
