Description

СПОСОБ METHOD

Изобретение относитс  к способам изготовлени  термоизол ционной оболочки на трубчатых издели х, образуемой из жидкой термоизол ционной смеси типа пенобетона, заливаемого в формы под давлением с последующей выдержкой и термообработкой.The invention relates to methods for producing a heat insulating shell on tubular articles formed from a liquid heat insulating mixture of a type of foam concrete, poured into molds under pressure, followed by aging and heat treatment.

Известный способ предусматривает покрытие теплоизолирующим материалом отдельной трубы или ее звена в отдельной камере и укладку ее на трассе после отвердени  термоизол ционной оболочки.The known method provides for coating a heat-insulating material with a separate pipe or its link in a separate chamber and laying it on the track after the heat-insulating sheath cures.

Целью изобретени   вл етс  повышение плотности оболочки и предупреждение расслоени  смеси.The aim of the invention is to increase the density of the shell and prevent the mixture from splitting.

Дл  этого трубчатые издели  располагают по русно с зазором в блок-формы, сообщающиес  между собой сквозными отверсти ми, где образование термоизол ционного сло  происходит одновременно.For this, the tubular products are arranged in an abraded way with a gap in the block forms, which communicate with each other through holes, where the formation of the thermal insulation layer occurs simultaneously.

После выдержки издели  подвергают термовлажностной обработке в течение 14-16 час под давлением 8-12 атм.After exposure, the product is subjected to heat treatment for 14-16 hours under a pressure of 8-12 atm.

Сущность предлагаемого способа по сн етс  чертежом.The essence of the proposed method is illustrated in the drawing.

давлением заливаетс  в ее полость через внутренние сквозные отверсти  2. Затем термоизол ционна  смесь уплотн етс  в полост х  русно-разъемной формы и выдерживаетс  в неподвижном состо нии в течение 12 час. После этого трубчатые издели  подвергают термовлажностной обработке под давлением 8-. 12 атм в течение 14-16 час.pressure is poured into its cavity through the internal through holes 2. Then the thermal insulating mixture is compacted in the cavities of an ovoid-separable form and kept in a stationary state for 12 hours. After that, the tubular product is subjected to heat treatment under pressure of 8-. 12 atm for 14-16 hours.
