Abstract
A method has been developed for determining the heater power at the cooling stage when welding polyethylene pipes for gas pipelines at low ambient temperatures (below those recommended by regulatory documents). Efficiency of the method is verified by studies of materials crystallization kinetics in the heataffected zones of welded joints
Supporting agencies: The reserch was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation No 122011100162-9.
