Изобретение относится к способам защиты металлических трубопроводов от коррозии и может быть использовано в нефтедобывающей и других отраслях промышленности, где применяются трубопроводы для перекачки нефти и других агрессивных жидкостей. Способ футеровки металлических труб термопластичным покрытием включает введение внутрь этих труб заготовки из термопластичного материала в форме трубы, прижатие заготовки к поверхности трубы при нагреве участков заготовки с постепенным перемещением зоны обогрева. При этом используют заготовку в форме трубы с наружным диаметром, соответствующим внутреннему диаметру металлической трубы. Перед введением в металлическую трубу заготовку нагревают, подвергая в нагретом состоянии обратимой вытяжке с уменьшением диаметра с последующим охлаждением до комнатной температуры в вытянутом состоянии. После введения заготовки в металлическую трубу прижимают ее к поверхности трубы при нагреве заготовки от одного конца трубы до другого до температуры не ниже температуры первоначального нагрева. Это позволяет упростить способ футеровки металлических труб, обеспечить повышение надежности футеровки и увеличение пропускной способности трубопровода.The invention relates to methods for protecting metal pipelines from corrosion and can be used in the oil and other industries that use pipelines for pumping oil and other corrosive liquids. The method of lining metal pipes with a thermoplastic coating involves inserting a billet of thermoplastic material in the form of a pipe into these pipes, pressing the billet to the surface of the pipe during heating of the billets with gradual movement of the heating zone. A blank in the form of a pipe with an outer diameter corresponding to the inner diameter of the metal pipe is used. Before introduction into the metal tube, the billet is heated, subjecting it to a heated state in a reversible stretch with a decrease in diameter, followed by cooling to room temperature in the stretched state. After the billet is inserted into the metal pipe, it is pressed against the surface of the pipe when the billet is heated from one end of the pipe to the other to a temperature not lower than the initial heating temperature. This allows us to simplify the method of lining metal pipes, to ensure increased reliability of the lining and increase the throughput of the pipeline.
