Изобретение относитс  к Способу соединени  эмалированных труб лутем сварки их концевых участков.This invention relates to a process for joining enamelled pipes by welding them at their end portions.

Цель изобретени  - исключение отслаивани  эмали.The purpose of the invention is the elimination of enamel flaking.

Достигаетс  это тем, что на коицевые участки впутрен ей поверхности трубы нанос т слой коррозиопностойкой стали леременного сечени  с уклоном к концу трубы и с наследующим эмалированием остальной трубы. Уклон сло  коррозионностойкой стали составл ет 1 :20-1 :50.This is achieved by applying a layer of corrosion-resistant steel of section with a slope to the end of the pipe and with subsequent enameling of the rest of the pipe. The slope of the corrosion resistant steel layer is 1: 20-1: 50.

Сущность способа по сн етс  че1ртежом.The essence of the method is illustrated by flipchart.

На концевые участки трубы 1 со стороны поверхности, подлежащей эмалированию, методом наплавки нанос т слой 2 коррозионностойкой стали. Затем производ т механическую обработку наллавленнаго сло  2 таким образом, что его тол|Щина увеличиваетс  от О до 2 мм в направлении к торцу трубы. Одновременно производ т разделку кромок -поц сварку.A layer 2 of corrosion-resistant steel is deposited on the end portions of pipe 1 from the side of the surface to be enameled by surfacing. Then the machined layer 2 is machined in such a way that its thickness increases from 0 to 2 mm toward the pipe end. At the same time, edge cutting is performed - welding is performed.

После подготовки поверхности нанос т слой 3 эмали на поверхность трубы 1, при этом эмалируют и .слой коррозионностойкой стали 2 за исключением зюны шириной около 20 мм, приле-гающей к торцу трубы. После лроверки сплошнасти эмалевого покрыти  трубы стыкуют путем наложени  шва 4.After surface preparation, a layer of 3 enamel is applied to the surface of pipe 1, while enameling is also made of a layer of corrosion-resistant steel 2, with the exception of a sjune about 20 mm wide, adjacent to the pipe end. After leveling the enamel coating, the pipes are joined by stitching 4.

Пред мет изобретен и  Prev invented and

1. Способ соединени  эмалированных труб путем сварки их концевых участков, отличающийс  тем, что, с .целью исключени  отсланвани  эмали на концевые участки внутренней поверхности труб, нанос т слой коррозионностойкой стали Переменного сечени  с уклоном к торцу трубы с последующим эмалированием остальной трубы.1. A method of joining enamelled pipes by welding their end sections, characterized in that, in order to prevent enamel from being expelled onto the end sections of the inner surface of pipes, a layer of corrosion-resistant Variable Section steel with a slope to the end of the pipe is applied with subsequent enameling of the rest of the pipe.

2. Способ по П. 1, отличающийс  тем, что уклон сло  коррозионностойкой стали составл ет 1 : 20-1 : 50.2. The method according to claim 1, characterized in that the slope of the layer of corrosion-resistant steel is 1: 20-1: 50.
