Gas transmission pipelines
Stroytransgaz has realized various projects over the course of ten years for construction of gas transmission pipelines in Finland. Application of proprietary quality management systems has enabled Stroytransgaz to win the respect of Finnish company-customers Neste, Gasum Oy, and Yit Rakennus Oy.
Imatra-Lappienranta
During 1996 and 1997 Stroytransgaz built a parallel branch of the Imatra-Lappienranta, a 48-kilometer pipeline of 36 inches in diameter. Company specialists used welding spread method of pipe welding, thereby achieving rapid pace in welding-assembly work. Thanks to this technology, the customer was able to obtain Russian gas a month earlier than originally scheduled.
Lappienranta-Luumiaki
During 2000 and 2001, in a consortium with Spetsstroymontazh, Stroytransgaz realized a project to build the 24-kilometers Lappienranta-Luumiaki pipeline; it has a diameter of 36 inches.
Kjumiyoky-Nijnikosky
In 2006 Stroytransgaz built the Kjumiyoky-Nijnikosky parallel gas pipeline. It has a length of 45 kilometers and a diameter of 28 inches. Stroytransgaz performed welding and assembly work, completed crossings of natural and man-made barriers, prefabricated and erected valve stations, conducted hydrotesting and drying of the pipeline to –20°C, and calibrated the pipe with an intelligent pig.
