Stroytransgaz employs a number of progressive technologies, equipment and materials in construction of oil and gas facilities:
Development of the production base and technical retooling of machine-building enterprises:
Technical requipment of construction organizations:
APPLYING HIGH TECHNOLOGIES FOR GAS AND OIL PIPELINE CONSTRUCTION
Crossings by a horizontal directional drilling method
Said technology allows to construct oil and gas pipelines and other communication installations across all kinds of obstacles – just passing under them. In the course of Russia-Turkey gas pipeline construction (Blue Stream Project) 6.0 km of river crossings by HDD method was performed. The longest one is 900 m long.
Construction of tunnel crossings of the Main Caucasian ridge
Construction of the first European standard tunnels in Russia for a high pressure main gas pipeline made it possible to minimize the harmful effect on the environment and ensure a reliable protection of the pipeline against corrosion and landslide. Three tunnel crossings of the Kobyla and Bezymianny ridges were constructed, with 2.1 m in diameter and correspondingly 2082, 988 and 196 m in length.
NEW ALL-SEASON TECHNOLOGY OF TESTS OF MAIN GAS PIPELINES
For the first time in the Arctic conditions during commissioning of a pipeline section 101.7 km long 1420 mm in diameter of the Zapoliarnoe – Urengoy gas pipeline during the winter season new technology of testing of pipelines was used which was elaborated by Stroytransgaz together with the experts of Research Engineering Company Ltd. "Buster" and Ltd. "SOTEGA". This technology provides for filling of the section under test with gas taken from the first line under operation and rising the pressure in it up to the test pressure of 8.25 MPa with the help of boosters. Two loopings of this pipeline 39 and 62.7 km long were tested during 17 days with the use of three self-propelled pumping and compressor units of UNG 8/15 type manufactured at the compressor plant of the "Borets" Joint-Stock Company. Flexible characteristics of gas compression provided by boosting pump and compressor units ensure at the unit outlet the required test pressure of the main gas with the capacity of 120 m3/min. In this case the pressure at the inlet of the unit may range from 5.9 to 7.4 MPa.
The elaborated technology allows one to ensure pumping of the gas after completion of testing from the gas pipeline section under test back to the gas pipeline under operation. Such a technology ensures considerable savings of natural gas and is much cleaner from the ecological point of view even in comparison with the tests when air or liquid (water) is used.
The most important advantage of the elaborated technology is the possibility to carry out strength and leak tests of pipelines in any weather conditions including arctic ones.
The elaborated technology can also be widely used during tests after performance of repairs on the gas pipelines under operation.
WELDING TECHNIQUES
Stroytransgaz has the most modern techniques and equipment for welding pipes of large diameter and this enables one to ensure high quality and reliability when executing the most vital operations during construction of pipelines.
The CRC-AW complex of automatic gas-arc welding
This technology is used for mass-scale welding of pipes at long sections by highly productive complexes equipped with computer system for monitoring the welding process and has a program control system for change of welding modes depending on spatial position of the welding head for each layer of the weld.
The Innershield technology
This is semi-automatic welding by using flux-cored wire. This technology is used particularly at very complicated sections of the route in severe climatic conditions.
Flash-butt welding
This technology is used for welding of pipes of large diameter in the Far North and enables one to exclude the influence of the weather and human factor on the quality of welding.
CONSTRUCTION AND RENOVATION OF COMPRESSOR AND BOOSTER STATIONS, BUILDING OF UNDERGROUND GAS STORAGE FACILITIES AND MODULES
Stroytransgaz take an active part in the constructing of mainline gas compressor stations of various capacity and other facilities of industrial and social infrastructure/
From 1995 to 2005 16 compressor stations with total capacity of 1117 MW were constructed at main gas pipelines.
From 1995 to 2005 21 booster compressor stations with total capacity of 1576 MW were constructed at Urengoy and Yamburg gas condensate fields.
From 1995 to 2005 18 main pipeline compressor stations with total capacity of 650 MW were renovated and upgraded using Tragaz Consortium equipment.
In the course of the Yamburg gas condensate field construction 252 super modules, each of 350 - 500 tons, were applied.
