Petrotec and Lokring have recently helped a major oil and gas operator in Qatar by installing Lokring flanges to connect piping offshore. The solution is completely ‘weld-free’ and has helped our client to reduce the time, cost and risk associated with welding activities or other traditional means to connect small bore piping. Lokring designs patented, weld equivalent pipe and tube fittings such as couplings, flanges, elbows, adapters, and more. The unique technology of the patented Lokring fittings utilize Elastic Strain Preload (ESP) and possesses a metal-to-metal leak-free seal providing a connection equivalent to a butt weld in only 15 minutes.
