884 Megawatt Suki kinari hydropower project is being constructed in the difficult geological terrain of Kaghan Valley since 2017. The Project is Pakistan’s highest head Hydropower with a long headrace tunnel and twin penstock system including horizontal pressure tunnels and shafts.
Due to the high pressure, poor geological condition, and faults, approximately 2000m twin penstock tunnels & shafts are lined with steel pipes. To fabricate the Steel, a state-of-the-art steel factory was established with in the construction site area with the average monthly production capacity of 735 tons.
The factory is equipped with a 4,000 tons hydraulic press, gantry cranes, C N C cutting machine, welding cross arm, and a bunch of other advanced equipment. The peak monthly manufacturing capacity is 950 tons. By the end of 2022, the fabrication works of all steel liners have been completed. This steel factory produced over 15,000 tons of steel liners successfully.
The strict quality assurance system is exercised to detect the welding flaws. The non-destructive testing including VISUAL TESTING, ULTRASONIC TESTING, PENETRATION TESTING, and Time of Flight Diffraction (TOFD) is in practice. After sand blasting and painting, the cans were transported to the respective site.
Considering the complex nature of job, the good health, safety and Environmental practices are in place. The mock trainings and strict implementation are being insured during the job.
