METHOD FOR TRANSPORTATION OF A PRODUCT VIA A PIPELINE IN A PERMAFROST GROUND

摘要

The invention relates to the construction of trunk pipelines and can be used to transport products with a positive temperature when laying pipes in permafrost soil. The purpose of the invention is to reduce energy consumption during transportation of the product by completely eliminating the heat flux from the transported product with a temperature above the temperature of the soil surrounding the pipeline. To do this, measure the temperature of Ti on the surface of the laid pipeline like a pipe in a pipe with an annular space filled with insulating material and the temperature T2 of the soil surrounding the pipeline, regulate the temperature Ti and T2 from the condition Ti Ta by continuously removing heat from the surface of the internal pipeline. channels, fixed on the outer pipeline, and pass through them coolant with a temperature below the temperature T2 of the soil. 2 Il.
