Employees of Laboratory No. 8 at NIIK are the most sought-after specialists during shutdown repairs at enterprises in the nitrogen industry.

From June 15 to July 1, a team of NIIK specialists carried out repairs on the lining of the upper part of the urea synthesis reactor at Apatit JSC in Cherepovets, Russia. The scope of repair work included replacing four belts of the cylindrical part of the lining with a total height of 8300 mm, overflow pipes, a thermal jacket at the lower part of the apparatus, and the mass transfer tray. In addition to the planned work, a corrosion inspection of the urea synthesis reactor was conducted. From July 16 to 23, eddy current testing of equipment was performed, and five more apparatuses were inspected.

These planned activities will ensure the uninterrupted operation of the workshop and the achievement of production targets in the future.
