Abstract
Настоящее изобретение относится к области трубопроводного транспорта и может быть использовано для поддержания температуры трубопроводов в рабочем диапазоне, а также для защиты от замораживания трубопроводов и стартового разогрева трубопроводов до рабочей температуры. Трубопроводная система с подогревом включает по меньшей мере один участок металлической футерованной изолирующим слоем трубы, электроды, соединенные с металлической трубой, и источник электрического тока с системой регулирования. Особенность трубопроводной системы заключается в том, что в качестве футерованной трубы используют металлическую трубу, футерованную внутри каменным литьем, причем по длине трубы выполнены сквозные отверстия, в которых герметично вставлены электроды, одни концы которых имеют контакт с металлической трубой, а вторые - с прокачиваемой пульпой.The present invention relates to the field of pipeline transport and can be used to maintain the temperature of pipelines in the operating range, as well as to protect against freezing of pipelines and the initial heating of pipelines to operating temperature. The heated pipeline system includes at least one section of a metal pipe lined with an insulating layer, electrodes connected to a metal pipe, and an electrical current source with a control system. A distinctive feature of the pipeline system is that a metal pipe lined inside with stone casting is used as a lined pipe, and through the pipe there are through holes in which electrodes are inserted hermetically; .
