Abstract
Способ сварки полимерной трубы, заключающийся в оплавлении торцов трубы нагретым до или выше температуры плавления материала инструментом, осаживании после удаления инструмента оплавленных торцов под давлением и выдерживании под этим давлением определенное время в замкнутом ограниченном объеме, отличающийся тем, что время оплавления продлевают до достижения определенной глубины проплавления торца трубы, достигаемой при нормированных температурах, а скорость охлаждения сварного соединения обеспечивают за счет теплоты сварного соединения путем изменения соотношения холодной и прогретой частей сварного соединения внутри ограниченного объема при фиксированной высоте. A method of welding a polymer pipe, which consists in melting the ends of the pipe with a tool heated to or above the melting temperature of the material, depositing, after removing the tool, the melted ends under pressure and keeping them under this pressure for a certain time in a closed limited volume, characterized in that the melting time is extended until a certain depth is reached penetration of the pipe end, achieved at normalized temperatures, and the cooling rate of the welded joint is provided due to the heat of the welded soy Inonii by changing the ratio of cold and heated parts of the welded joint within a limited volume at a fixed height.
