In August 1951, a temporary pump station in Ufa, a segment of the products pipeline from Ufa to Berdjaush (Chelyabinsk region) and the Berdjaush filling station with a platform for simultaneous filling up of eight tetra-axial RVS-2000 tanks and a pump-filling station with two 5NDV pumps were commissioned, accompanied in December 1951 by construction of a head station in Ufa with a pump station equipped with 8МB9х2 pumping units and ЗV200х2 support stations with a goods park of 14 RVS-4600 tankers made of unkilled steel. At the same time, the Berdjaush – Sineglazovo segment and the Sineglazovo station with a filling platform, pump station and three 8NDV and 12 RVS-4600 units made of unkilled steel were commissioned. The product pipeline segment till Petropavlovsk was put into operation in 1953 together with an intermediary Kropachevo station and a filling Petropavlovsk station with a gallery-type platform, a pump station with two 8NDV units and a 6 tanker RVS-3200 and RVS-2000 park.

Construction of the linear part of the products pipeline (1176 km) was totally completed in 1954.

The intermediary Petropavlovsk pump station equipped with five NТ-45 pumps with the Scoda 65-350 diesel motor drives were commissioned in 1956. This pipeline throughput capacity reached its planned value of 2 million tons. By decision of the USSR Government, it was planned to boost this pipeline throughput capacity up to 3.9 million tons a year in the Ufa – Chelyabinsk segment and up to 3.5 million in the Chelybinsk – Omsk segment. To achieve this, pump stations were built: in 1957 – Asha and Travniki; in 1959 – Khokhly and Suslove; in 1960 - Isil-Kul. Commissioning of these stations marked a round-up of the total projected construction complex of the first Ufa – Omsk products pipeline. In late ’40s - early ’50s several oil fields of the Tujmazy and Ishimbaj type were prospected and partially explored.

This was followed by a decision on construction of the Tujmazy – Omsk oil pipeline, its project was endorsed by the USR Council of Ministers Resolution of March 28, 1951. The route went parallelly to the first Tujmazy – Ufa pipeline and the Ufa –Omsk products pipeline. Construction of an oil pipeline was commenced in February 1952. In winter period, only welding of pipes at the stationary plants was performed, and in May ground and insulation works had a good start.

On December 30, 1952, the Naryshevo – Subkhankulovo (127 km) and an experimental pump station at Node No. 1 of the head constructions in Subkhankulovo were put into operation, and the newly manufactured 8ND10х5 pumps were tried. The segment was looped to the first and second Tujmazy – Ufa oil pipelines.

In November 1954, the commission accepted a segment of the Tujmazy – Omsk pipeline (127 - 261 km), the Cherkassy oil pump station and a 350 mm dam form the head (Ufa) oil products pump station to the Cherkassy oil pump station.

In the same period, small length pipelines were built: Shkapovo - Ishimbaj, Almetjevsk - Kujbyshev, Bavly - Kujbyshev, Karabash - Bavly, Kujbyshev - Saratov, Vyshka - Krasnovodsk (second line), Pokrovsky - Syzran, Minnibajevo - Bavly, Romashkino - Klyavlino, Buguruslan - Kujbyshev, Ozek - Suat – Grozny, etc. The 144 km long Ozek - Suat – Grozny pipeline was commissioned in 1955. This was the first Soviet “hot” pipeline for pumping of high-viscosity heated oil.

As of January 1, 1957 (40th anniversary of the Great October Revolution), 11,500 km of trunk pipelines with 101 pump stations were operated.

Year 1957 saw the start of construction of the Trans-Siberian 720 mm, 3,662 km long Tujmazy – Irkutsk oil pipeline. The pipeline was constructed in two phases: Tujmazy - Omsk (1332 km); Omsk - Novosibirsk - Irkutsk (1639 km).

The first two segments of this pipeline were commissioned in 1959. In the same year, construction works on the second 530 mm, 1083 km long Ufa – Omsk oil pipeline were completed. In 1956, the 530 mm, 110 km long Almetjevsk – Aznakajevo – Subkhankulovo oil pipeline was constructed. It brought the Almetjevsk oil to Subhankulovo and further on to the Tujmazy – Omsk – Novosibirsk trunk pipeline. Before the end of construction of the 530 mm, 579 km long Almetjevsk – Gorky pipeline, oil was pumped along the first segment up to Chistopolsky quay on the Kama river. Then it was loaded on the tankers and delivered to the Gorky and Yaroslavl refineries. When the pipeline was commissioned, water shipments had been noticeably reduced.

In the sixth five-year-plan period, the 350 mm, 446 km long Almetjevsk – Perm and not very long Mukhanovo – Kujbyshev, Serny Vody - Krotovka, Chekmagush - Ufa (later part of the Ufa Kambarka product pipeline), Kaltasy -Ufa, Almetjevsk - Subkhankulovo - Orsk, Zhirnoje - Volgograd, Krotovka - Kujbyshev, Shkapovo - Subkhankulovo, Cheleken - Belek, Belek – Krasnovodsk pipelines were constructed.

In the sixth five-year-plan period the already known Astrakhan – Urbakh – Saratov product pipeline received a new life. It became an oil pipeline and changed its pumping orientation. The development of oil refine industry in the eastern region has removed the demand in the oil product supplies to these regions, and the pipeline load went down to 30 %. Upon commissioning of the Kujbyshev – Saratov pipeline, a 49 km long branch was built to connect it with the Urbakh pump station, which transferred oil to the southern plants. This pipeline further exploitation had demonstrated its high reliability and allowed to unload the railroad transport. The 65 km long Urbakh – Saratov segment was now used for pumping of the Stepanovsky field oil.

In 1959, the Council for Mutual Economic Assistance (SEV) adopted a decision on construction of a unique
