Abstract
Mobile system MKT 1420 of the equipment for heat treatment of welded joints on pipelines is described. Its capabilities are shown for optimization of the preset modes of heating using flexible electrical resistance heaters. Peculiarities of design are considered, and comparative characteristics of sectional resistance heaters intended for heat treatment of welded joints and local heating of pipelines are presented.
