Project Overview:
The 30-inch Tabriz–Armenia gas transmission pipeline was designed and constructed to facilitate the export of natural gas from Iran to Armenia, with a daily capacity of 10  million cubic meters.
The pipeline originates from the Tabriz Gas Compression Station and stretches 115  kilometers to the Armenian border near the village of Norduz, adjacent to the Aras River
Execution Activities:
– Pipeline Diameter: 30  inches
– Length: 115  kilometers
– Transmission Capacity: Approximately 10 million cubic meters of gas per day
– Pipe Wall Thickness: 0.375”, 0.438”, 0.562”, and 0.688”
– Steel Grade: API 5L X52
– Project Duration: Planned for 900  days, completed in 650  days
