Description

Известные способы футеровки труб термопластами заключаютс  либо в накладывании соответствующей замазки на внутреннюю иоверхность трубы, либо в запрессовке предварительно разогретых термопластичных труб в металлические меньшего диаметра.The known methods of lining pipes with thermoplastics consist either in applying appropriate putty to the inner surface of the pipe, or in pressing in preheated thermoplastic pipes into metal of smaller diameter.

Описываемый способ футеровки металлических труб термопластичными материалами отличаетс  от существующих способов тем, что плотное прилегание трубы из термопласта к стенкам металлической трубы достигаетс  за счет сн ти  внутренних напр жений в формованной трубе, номещенной в термостат .The described method of lining metal pipes with thermoplastic materials differs from the existing methods in that a tight fit of a thermoplastic pipe to the walls of a metal pipe is achieved by relieving internal stresses in a molded pipe placed in a thermostat.

Способ заключаетс  в том, что вначале при определенном тепловом режиме формуют трубу из термопластичного материала, вследствие чего в ней возникают значительные внутренние напр жени . После этого пластмассовую трубу ввод тThe method consists in forming a pipe of a thermoplastic material at a certain thermal regime, as a result of which considerable internal stresses arise. Thereafter, a plastic pipe is introduced.

в металлическую с минимальным зазором между ними и помещают обе трубы в термостат. При температуре 110-125°, снимают внутренние напр жени , создава  плотное прилегание пластмассовой трубы к стенкам л еталлической трубы.in a metal with a minimum gap between them and put both pipes in the thermostat. At a temperature of 110-125 °, the internal stresses are removed, creating a tight fit of the plastic pipe to the walls of the metal pipe.

Футерованные таким способом трубопроводы в услови х повыщенных температур и агрессивнь,1х сред не деформируютс .Pipelines lined in this way under conditions of elevated temperatures and aggressive, 1x media are not deformed.
