Lokring
Lokring is a cold installation method for assembling an indefinite weld equivalent of pipe connections, eliminating the need for hotwork and the associated health and safety issues. Lokring is used as a hybrid solution along with a prefabricated pipe spool for installation as well as repair of existing piping. Generally used for smaller pipe connections.
