As it is known, the underground layer of natural gas is of a high pressure. A high pressure of the layer is partially used for transportation of natural gas through the main pipelines at considerable distances to the consumption site. In case of gas combustion in the industry or in a life, its pressure should be considerably lowered in comparison with the pressure in the main pipelines. This decrease usually occurs due to throttling.
