Portable Mirage milling machine technology ensured accurate metal-to-metal sealing for vessel covers and heat exchangers during maintenance work by specialty mechanical services company, Hydratight, at an industrial complex in Germany during the plant’s annual shutdown.
A team of 40 Hydratight engineers from Germany, Holland, France, and the UK, operating under COVID-19 restrictions, was tasked with lifting vessel covers, performing on-site machining and controlled bolting on a number of vessels and heat exchanger joints, within the 45 day shutdown.
