PLANT FOR PNEUMATIC TESTS OF PIPELINE AND METHOD OF PNEUMATIC TESTS OF PIPELINE (VERSIONS) Russian patent published in 2010 - IPC F17D5/00 F17D5/02 G01M3/08 

FIELD: construction industry.

SUBSTANCE: plant for pneumatic tests of pipeline includes container wherein the main system is located. System consists of centrifugal and piston-type compressors equipped with gas turbine drive and connected in various combinations to pipeline by means of air supply lines, system of coordination of modes of simultaneous operation of compressors and various units, and namely: regulating cock, units of air coolers and moisture separators, three-way valve, shutoff pass valves, control unit of piston-type compressor start-up and air flow of centrifugal compressor, converters of operating parametres of the plant. Methods of pneumatic tests of pipeline consist in the fact that the plant is activated and medium is delivered immediately from centrifugal compressor or through piston-type compressor to pipeline. Operating parametres of the plant are constantly recorded and controlled. Before air is supplied to pipeline, it is cooled, and condensed moisture is removed.

EFFECT: improving operating reliability of the plant at pneumatic tests of pipelines in various climatic conditions.
