Welding Polymer Pipes at Low Climatic Temperatures

The results of the research on development of technology for welding polymer pipes at low climatic temperatures in open air without the use of temporary heated structures are presented. The most common welding methods are considered: butt welding with a heated tool, electrofusion welding with embedded heating element and socket welding. Tests on welded joints show that the developed technology for welding in open air without the construction of shelters provides the same level of quality as when welding at admissible temperatures.
