When designing, the requirements of current regulatory documents of Transneft, federal legislation in the field of industrial, fire and environmental safety were taken into account.  

During the project implementation, an underground pipe section with a diameter of 720 mm will be laid. The section to be revamped crosses highways, including a section of the Samara – Orenburg federal route, as well as overhead and underground utilities. Highway crossings will be made by laying 1,020 mm diameter pipes with a three-layer polyethylene factory insulation coating in a protective sleeve.

Pipes of K56 strength class or higher with a wall thickness of 8 mm (second quality level) were selected for the pipeline section construction. There are no plans to install line stop valve units in the project area.

The work is scheduled to begin in 2022.
