Project Outline
The 16-inch, 0.203-0.281-inch thick, tar-coated, 70-Kilometer
Aliabad-to-Shahrood Gas Pipeline passed through one of Iran's roughest terrains.
The pipeline branched out from Sarakhs/Neka main pipeline at km 641+700 to reach
the outskirts of the city of Shahrood, traversing seemingly impassable
mountains, marshlands, forests and rivers.
Main Features
- Volume of Excavation in
Normal and Rocky Terrain: 2.2 Million Cubic Meters
- Excavation in Rocky Terrain:
1.3 Million Cubic Meters
- Explosives: 27 tonnes
From Kilometer 0-10, the pipeline
passed through farm fields and marshlands; from kilometer 10-24 through forests,
semi-mountainous regions, rivers and swamps; from kilometer 10-24 through
impassable mountains with slopes of 30 to 60 percent, under freezing
temperatures, fog and constant rainfall; from kilometer 40-70 through farmlands
and orchards, rising up to 2300 meters above the main pipeline from which it
originally branched out.
