Successful clamshell installation and emergency on-site repair at a Nitric Acid Plant in Uzbekistan

On this occasion our On-Site team did an brilliant job at a Nitric Acid Plant located in Navoi, Uzbekistan, 470 km from Tasken, the capital.

In record time, at MACOGA facilities we manufactured a high pressure reinforced clamshell Alloy 625 gr. 1 LCF and immediately our team traveled from Spain to the plant with all the necessary material to install a same-size clamshell in a heat exchanger.
