Изобретение относится к области предохранения труб от коррозии и может быть использовано при изготовлении, монтаже и ремонте трубопроводов, предназначенных для транспортирования нефти, нефтепродуктов, газа, различных агрессивных сред, воды и т.д. Для обеспечения сплошности антикоррозионного покрытия внутренней поверхности труб после сварки способ предусматривает использование втулки из коррозионно-стойкого материала, которую устанавливают во внутрь двух соединений свариваемых между собой труб и перекрывают втулкой зону влияния тепла от сварки на термочувствительное покрытие в трубах. Уплотнение между наружной поверхностью втулки и покрытыми поверхностями сваренных труб осуществляют запрессовкой втулки в сваренные трубы, при этом запрессовку осуществляют путем высокоскоростного пластического деформирования втулки.The invention relates to the field of protection of pipes from corrosion and can be used in the manufacture, installation and repair of pipelines intended for the transportation of oil, oil products, gas, various corrosive media, water, etc. To ensure continuity of the anticorrosion coating of the inner surface of pipes after welding, the method involves the use of a sleeve of corrosion-resistant material, which is installed inside the two joints of the pipes being welded together and cover the sleeve with the zone of influence of heat from welding on the heat-sensitive coating in the pipes. The seal between the outer surface of the sleeve and the coated surfaces of the welded pipes is carried out by pressing the sleeve into the welded pipe, while the pressing is carried out by high-speed plastic deformation of the sleeve.
