Pipelines for the transportation of natural gas, cold water supply and drainage are one of the most significant elements of urban and rural infrastructure. Pipelines from polymer materials, in particular polyethylene, are a modern alternative to steel pipelines, which during 15–20 years of operation are destroyed under the influence of chemical and electrochemical corrosion. In the world and in Ukraine, almost all new distribution pipelines for gas, cold water supply and drainage are constructed from polyethylene pipes. In Ukraine, especially in large cities, a practice of replacing old worn-out steel pipelines by new polyethylene ones and renovation using the method of inserting a polyethylene pipe into steel pipeline has become widespread. One of the most technological methods of joining of polyethylene pipes of almost the whole range of outer diameters is butt welding with a hot tool. The equipment for this welding method is currently not manufactured in Ukraine. The imported installations for butt welding of polyethylene pipes are operating according to the conventional technological scheme developed a long time ago, some elements of which, due to the improvement of the polymer materials themselves, can be revised and simplified preserving a high quality of final welded joints. The aim of the work is to review the state of the art in the field of butt welding of plastic products, first of all, polyethylene pipes with a hot tool and its modifications, which are the most interesting from the technological point of view. 28 Ref., 5 Figures.
Keywords: butt welding with a hot tool, plastics, polyethylene pipes
