Calculation of soil temperature at the intersection of the heating line of the underground gasket and gas pipeline taking into account real operating conditions

Distances from the insulation shell of pipelines duringchannelless laying to utility networks are recommended by regulatory documents, but in real conditions it is not always possible comply with these parameters. Calculations have been made verify that gas pipeline can be laid next supply heating network problematic section installation where restrictions met. The soil temperature on wall case determined exclude condition polyethylene pipes above 40 °C for entire period operation. Soil temperatures at intersection line and were taking into account operating district networks, peculiarities regulating coolant parameters Russian heat systems state thermal insulation.
