The design procedure of installation is developed for an estimation of behaviour of heat-transfer agent in the main pipelines, as distributed parameter systems. The description is based on two equations Navie-Stokes and the indissoluble environment equation. The solution is two equations of speed and pressure. At calculation of system of the equations it is based on with use of dependence of density from temperature and pressure and a derivative of pressure on density. Search of the given components is based on temperature of heat-transfer agent in the set point of the pipeline based on a balance equation of heat amount in the pipeline, in view of available thermal losses, properties of the insulating materials.
