Description
Изобретение относитс к технике изол ционных работ при строительстве трубопроводов , в частности к нанесению дтепло- и гидроизол ции на трубы.The invention relates to the technique of insulation works in the construction of pipelines, in particular to the application of thermal and hydraulic insulation on pipes.
Известен способ тепло- и гидроизол ции трубы в разъемной форме, по которому на внутренних стенках с()ормы размещают гидроизол ционный материал в виде пленки и прижимают его к стенкам формы, нагретой до +100С гор чим воздухом, затем подают в полость между трубой и пленкой вспенивающуюс теплоизол ционную композицию , а после вспенивани и отверждени последней трубу охлаждают, обеспечива плотное прилегание гидроизол ционной пленки к теплоизол ции при усадке 1The known method of heat and water insulation of a pipe in detachable form, along which waterproofing material is placed in the form of a film on the inner walls with () forms and pressed against the walls of the form heated to + 100 ° C with hot air, then is fed into the cavity between the pipe and foaming insulating composition of the film, and after foaming and curing the last tube is cooled, ensuring a tight fit of the waterproofing film to the heat insulation during shrinkage 1
Известный способ не обеспечивает монолитности изолирующих слоев, что снижа,ет надежность изол ции трубы.The known method does not ensure the solidity of the insulating layers, which reduces the reliability of pipe insulation.
Дл получени монолитной теплогидроизол ции термообработку провод т в дву.х режимах: вспенивание и отверждение теплоизол ции при температуре + 60°С, а сплавление гидроизол ции с теплоизол цией при повышении- температуры до + ЗООТ,To obtain monolithic heat-insulating heat treatment is carried out in two modes: foaming and solidification of heat insulation at a temperature of + 60 ° C, and fusion of waterproofing with heat insulation with increasing temperature to + ZOOT,
Предложенный способ осуществл етс следующим образо.м.The proposed method is carried out as follows.
На внутреннюю поверхность разъемной формы при температуре 15-20 C путем пульверизации нанос т гидроизол ционный компонент в виде сло мастики, например из термопласта с битумом, укладывают в нижнюю часть горизонтальной формы изолируемую трубу и заливают ее жидкой композицией пенопласта, например фенольного или полиуретанового, после чего форму герметизируют и подают в термокамеру, где в течение 3-5 м при температуре + теплоизол ционна композици вспениваетс и отверждаетс . После отверждени теплоизол ции повыщают температуру термообработки до + 300°С, обеспечива в течение до 30 м сплавление гидроизол ционного компонента со слоем теплоизол ции. После снижени температуры до + 60°С производ т распалубку изолированной трубы.A waterproofing component in the form of a mastic layer, for example, from a thermoplastic with bitumen, is placed on the inner surface of a detachable form at a temperature of 15–20 C, the insulated pipe is placed in the lower part of the horizontal form and filled with a foam plastic composition, for example, phenolic or polyurethane, after whereby the mold is sealed and fed to a heat chamber, where for 3-5 m at a temperature + the heat insulating composition foams and cures. After curing, the heat insulation increases the temperature of heat treatment to + 300 ° С, providing for up to 30 m the fusion of the waterproofing component with the heat insulation layer. After the temperature has decreased to + 60 ° C, the insulated pipe is disassembled.
Продолжительность одного цикла работы зависит от диаметра изолируемой трубы.The duration of one cycle of work depends on the diameter of the insulated pipe.
