Today at the construction of the main gas pipeline Russia – Turkey (“Blue Stream”) OAO Stroytransgaz has completed the process of pneumatic tests of section km 307 - km 370 from the Krasnodarskaya compressor station up to the Beregovaya compressor station in the Caucasus Mountains.
As stated by the test commission the testing of one of the most complicated Russian sections of the mainline was carried out successfully by observing all the required parameters. Considering the peculiarities of the relief the test of the gas pipeline was carried out by a traditional method with compressed air by increasing the pressure up to 110 atmospheres. Prior to the tests the interior space of the pipeline was cleaned by air with the help of compressors and cleaning pigs, this work was carried out by IP Belstroytransgaz - the subsidiary company of OAO Stroytransgaz. As a result, the pipes were made free of the remains of electrodes, earth and water. Preparation of the gas pipeline for the tests was carried out by OAO Zakneftegazstroy – Prometheus (the city of Erevan) and the test process was carried out by DAO Orgenergogaz. At present preparatory works are being carried out for the drying process of the pipeline in the mountainous area. The plain part of the Russia – Turkey gas pipeline, as requested by the Client of the project – OAO Gazprom, is subjected to tests by using a stress-test method in accordance with the European standards of Vd TŰV Merkblatt Rohrleitungen 1060. The modern technology of the stress-test method is a hydrostatic method of testing of a pipeline for strength and leakproofness, whereby the installed section of the gas pipeline is filled with water by raising the pressure up to the test level. For carrying out trial and commissioning works at the “Blue Stream” project it has been planned to start supply of the gas in mid-November.
