Рассмотрены защитные свойства фторопластовых покрытий с целью возможности их применения в качестве внутренних покрытий магистральных газопроводов, с учетом специфичных условий эксплуатации. Проведенные исследования на стойкость к воздействию воды, растворителя и соляного тумана показали высокие защитные свойства покрытия. По результатам изучения сплошности покрытия электроискровым методом установлено отсутствие пропусков в покрытии при толщине, соответствующей требованиям нормативно-технической документации. Исследование покрытия на стойкость к воздействию низких температур показало сохранение внешнего вида без следов растрескивания. По результатам работы сделаны выводы, что рассматриваемые фторопластовые покрытия обладают высокими защитными и диэлектрическими свойствами, а также требуемой для низкотемпературных климатических зон Крайнего Севера хладостойкостью. Таким образом, покрытия на основе фторопластовых полимеров можно рекомендовать в качестве внутренних защитных покрытий магистральных газопроводов, в том числе расположенных в районах Крайнего Севера.
