During a planned 72-hour shutdown of the Kuybyshev – Lisichansk OTP, specialists of the Samara RPD carried out midlife repairs of five gate valves, dismantled MPU No. 2 for subsequent replacement and cut out a defect of the supply oil pipeline at the Samara-2 oil pumping station (PS). MPU No. 3 was installed and seven substandard air escape valves were eliminated at the Sovkhoznaya-3 PS. Specialists of the Volgograd RPD connected a newly constructed oil meter skid for oil outflow at the Krasnyi Yar LODS.

During a 72-hour planned shutdown of the Krasnoarmeysk – Saratov Refinery OTP, specialists of the Saratov RPD replaced two check valves and connected a supply pipeline to the oil and petroleum products’ lease automatic custody transfer unit (LACT) at the Krasnoarmeyskaya-3 oil pumping station.

In addition, specialists of the Samara RPD connected temporary PIG traps to the pressure oil pipeline of the Samara-1 PS. The work was carried out during a scheduled shutdown of the Kuybyshev – Unecha-2 oil trunk pipeline at the Samarara – Klin section within 72 hours.
