Method for increase of gas pressure in distribution gas pipelines and gas pipelines – branches includes installation on sections of gas pipelines where working gas pressure Prob is smaller than 90 % of calculated gas pressure Prorb, of devices for increasing gas pressure and increase of working gas pressure Prob to values of calculated gas pressure Prorb. Before devices for increase of gas pressure one installs filters for gas purification with removal of admixtures and fine particles, with control of level of pollution of those with additional manometers installed before and after filters. By indications of manometers one performs replacement of filters for gas purification, with control of pressure and stability of operation of pressure indicators by means of manometers installed on gas pipelines – branches. |
