Abstract
1. Способ создания износостойкого полимерного покрытия на внутренней поверхности трубы, включающий введение в полость трубы рукава из модифицированного термопластичного полимера и его нагрев, отличающийся тем, что габаритные размеры указанного рукава в поперечном сечении, по крайней мере, на 10% меньше внутреннего диаметра трубы, при этом рукав при нагреве способен увеличиться в диаметре до размера, по крайней мере, на 10% превышающего внутренний диаметр трубы. ! 2. Способ по п.1, отличающийся тем, что рукав предварительно деформирован в поперечном сечении так, что его габаритные размеры в поперечном сечении меньше внутреннего диаметра трубы до 3-х кратного значения, при этом в процессе нагрева рукав принимает цилиндрическую форму и увеличивается в диаметре. ! 3. Способ по п.2, отличающийся тем, что деформированный рукав имеет в поперечном сечении U-образную форму. ! 4. Способ по п.1, отличающийся тем, что нагрев осуществляют горячей газообразной или жидкой средой, подаваемой во внутреннее пространство полимерного рукава, введенного в трубу. ! 5. Способ по п.1 или 4, отличающийся тем, что рукав нагревают до температуры 100-170°С.1. A method of creating a wear-resistant polymer coating on the inner surface of the pipe, comprising introducing into the pipe cavity a sleeve of a modified thermoplastic polymer and heating it, characterized in that the overall dimensions of the specified sleeve in the cross section are at least 10% smaller than the inner diameter of the pipe, while the sleeve during heating is able to increase in diameter to a size of at least 10% larger than the inner diameter of the pipe. ! 2. The method according to claim 1, characterized in that the sleeve is pre-deformed in the cross section so that its overall dimensions in the cross section are less than the inner diameter of the pipe to 3 times the value, while during heating the sleeve takes a cylindrical shape and increases in diameter. ! 3. The method according to claim 2, characterized in that the deformed sleeve has a U-shape in cross section. ! 4. The method according to claim 1, characterized in that the heating is carried out by hot gaseous or liquid medium supplied to the inner space of the polymer sleeve introduced into the pipe. ! 5. The method according to claim 1 or 4, characterized in that the sleeve is heated to a temperature of 100-170 ° C.
