Securing and containing the chemical contents of reactors is of vital importance. Nord-Lock Group provides state-of-the-art, proven solutions that keep a lid on your refinery’s hydrocracking, hydrotreating, hydrodesulfurization, and catalytic processes.

Nord-Lock Group’s corrosion-resistant solutions are ideal for demanding reactor cover applications. No matter the environment, Superbolt tensioners are available with plenty of product-enhancing options to keep things protected – helping to keep corrosion at bay. Additionally, our Nord-Lock washers are made from a wide variety of materials, and many are treated to withstand a minimum 1000 hours in a salt spray test per ISO 9227.

Severe vibration and dynamic loads cause reactor cover bolts to loosen, which can introduce contaminants to the chemical reaction process and expose equipment and personnel to harmful leaks and spills. Nord-Lock Group solutions prevent bolts from loosening, which increases operational reliability, reduces unplanned production interruptions, and lowers maintenance costs.
