RoydadNaft –  A project to upgrade the class of the final 10 kilometers of the Third Tehran Gas Pipeline, carried out in accordance with international standards and delivering savings of more than 2,000 billion rials, has commenced in Region 3 of Iran’s Gas Transmission Operations.

According to Roydad Naft, quoting the Public Relations Department of the National Iranian Gas Company (NIGC), Reza Emami, Manager of Region 3 Gas Transmission Operations, announced the development. He stated that following the approval of the NIGC Board of Directors for the class-change project on the final 10 km of the Third Tehran Pipeline, planning and preparation of the necessary infrastructure within the urban area were completed, and executive operations began in Tir 1405 (June–July 2026).

Emami highlighted the technical significance of the project, noting that it is being implemented based on the latest editions of recognized international standards, particularly in the areas of welding and hydrostatic testing, in order to enhance both safety and the reliability of the transmission line.

He added that the required pipes, after delivery from the Iranian Gas Engineering and Development Company, were prepared with polyethylene coating. Under the continuous supervision of the Corrosion Protection Unit and in cooperation with the Procurement and Materials Operations departments, the pipes underwent quality controls and were stockpiled in the region’s warehouses.

Emami emphasized that by relying on the region’s internal capabilities and assigning clear responsibilities to various units under the Pipeline Operations Deputy, the groundwork for project execution has been laid despite financial and equipment constraints. This approach, in addition to improving execution quality, will result in savings exceeding 2,000 billion rials.

He further noted that executive operations are currently underway, covering approximately 2,817 meters of class change across six separate sections. Upon completion, the project will mark an effective step toward enhancing the safety, stability, and reliability of Iran’s national gas transmission network.
