Investigation of the effect of heat fluxes on polyethylene cases

A study of the effect of heat fluxes on polyethylene cases has been conducted. Temperature fields from heating networks laid in impassable channels, in operating and emergency modes are con-structed. The calculated data indicate the possibility of using polyethylene cases at the intersection with heating networks. The conditions for laying polyethylene gas pipelines at the intersection with heating networks and the minimum distances at which polyethylene retains its strength characteristics are determined
