Abstract
Использование: нанесение защитных антикоррозийных битумнополимерных покрытий армированных стеклохолетом. Сущность изобретени : стекловолокнистый армирующий материал пропитываетс гор чей битумной или битумно-полимерной мастикой и навиваетс на вращающуюс трубу с нахлестом шириной 10-15 мм и нат жением 0,7-1,0 кг/см. 1 ил.Usage: the application of protective anticorrosive bitumen-polymer coatings reinforced with glass fiber. SUMMARY OF THE INVENTION: A fiberglass reinforcing material is impregnated with hot bitumen or bitumen-polymer mastic and wound onto a rotating pipe with an overlap of 10-15 mm wide and a tension of 0.7-1.0 kg / cm. 1 ill.
Description
Изобретение относитс к защите стальных труб от коррозии, в частности к способамнанесени на трубы битумно-полимерных покрытий, армированных стеклохолстом.The invention relates to the protection of steel pipes against corrosion, in particular to methods for applying bitumen-polymer coatings reinforced with fiberglass to pipes.
Цель изобретени - повышение переходного электрического сопротивлени , снижение водопоглощени и стоимости антикоррозионного покрыти за счет навивки армирующего стекловолокнистого материала , пропитанного гор чей битумной или битумно-полимерной мастикой на трубу с нат жением 0,7-1,0 кг/см и нахлестом шириной . 10-15 см.The purpose of the invention is to increase the transient electrical resistance, reduce water absorption and the cost of anticorrosion coating by winding a reinforcing fiberglass material impregnated with hot bitumen or bitumen-polymer mastic onto a pipe with a tension of 0.7-1.0 kg / cm and an overlap width. 10-15 cm.
Изобретение по сн етс чертежом.The invention is illustrated in the drawing.
Способ осуществл ют следующим образом .The method is carried out as follows.
Стальную трубу 1 очищают от ржавчины , нанос т на ее наружную поверхность грунтовку и устанавливают на свободно вращающиес ролики 2, один из которых вл етс приводным.The steel pipe 1 is cleaned of rust, a primer is applied to its outer surface and mounted on freely rotating rollers 2, one of which is driven.
Свободный конец рулонного армирующего стеклохолста 3, установленного наThe free end of the roll of reinforcing fiberglass 3 mounted on
шпуле 4, посредством нат жного ролика 5 погружаетс в ванну 6 подвижной каретки 7 и пропитываетс мастикой 8, затем приклеиваетс мастикой 8, затем приклеиваетс к трубе 1. Включаетс механизм (не показан) вращени трубы1 и перемещени комбинированной каретки 7 с ванной 5, оборудован-. ной электроподогревателем 9 и заполненной гор чей мастикой.the spool 4, by means of the tension roller 5, is immersed in the bath 6 of the movable carriage 7 and impregnated with mastic 8, then glued with mastic 8, then glued to the pipe 1. The mechanism (not shown) for rotating the pipe 1 and moving the combined carriage 7 with the bath 5 is turned on, equipped . electric heater 9 and filled with hot mastic.
Проход через мастику, армирующий стеклохолст пропитываетс ее и, увлека с собой некоторое количество мастики, навиваетс на трубу с нат жением 0,7-1,0 кг/см и с нахлестом шириной 10-15 см. При навивке и обжатии трубы мастика, наход ща с на нижней части армирующего стеклохолста , полностью заполн ет его поры и на наружной поверхности трубы образуетс надежный изол ционный слой.The passage through the mastic, the reinforcing fiberglass, is impregnated with it and, carrying with it a certain amount of mastic, is wound onto the pipe with a tension of 0.7-1.0 kg / cm and with an overlap of 10-15 cm wide. When winding and crimping the pipe, the mastic When sealed on the bottom of the reinforcing fiberglass, it completely fills its pores and a reliable insulating layer forms on the outer surface of the pipe.
Скорость движени комбинированной каретки с ванной, заполненной гор чей би- тумно или битумно-полимерной мастикой, выбирают по следующей зависимости:The speed of movement of the combined carriage with a bathtub filled with hot bitumen or bitumen-polymer mastic is selected according to the following relationship:
