Welding of polymer pipes of gas pipelines at low temperatures

Abstract

Taking into account the special features of the thermophysical processes of polymer materials, the authors propose methods of welding polyethylene pipes for gas pipelines in which welding can be carried out without temporary cover at low temperatures of atmospheric air.

Keywords:

• polymer material
• gas pipe line
