TeleGroup performs construction of gas pipelines with medium and high gas pressure as well as gas distribution networks. We offer complete services on a “turnkey” base, which include designing of the infrastructure through construction works and casing on gas digs and drilling sights, machine (welding) works on pipeline construction, isolation works with testing for electrical penetration, complete radiography of welds and testing the strength and tightness of the pipelines. 

Designing and construction of gas infrastructure

  • Production of all types of projects and complete project documentation
    Project types: Conceptual design projects, feasibility studies, detailed designs, built design, technical review of the main project
  • Integrated construction of gas and telecommunication infrastructure
    The advantages of integrated construction is reflected through a reduction of total costs, while simultaneously addressing two infrastructural problems – thus ensuring minimal disruption of functionality and appearance of settlements caused by excavation works.
  • Execution of construction works
    We offer services in mechanical and manual excavation along the route of the gas distribution networks, along with bringing the route back to its original state. We perform drilling with underground installation of steel (polyethylene) pipes with the diameter of up to Ø 1500mm and length of up to 120m.
