Permanent gas tight flange-to-pipe connections without welding

Page last modified

For almost 20 years, our patented Quickflange™ technology has built up a proven track record as a leading provider in cold work solutions, offering clients a permanent repair option for improving pipeline integrity and flow assurance eliminating the need for welding or hot work.

With an extensive range, Quickflange™ is a safe, cost-effective and efficient solution generating up to 80% time saving over traditional welding.

By combining our Quickflange™ connector with with our bespoke Quickflange activation tool, the process of installing a Quickflange weldless connector is both quick and easy.  Once the line is isolated a straight cut is crucial to ensure the Quickflange™ sits flush to the pipe edge.  The hydraulic tool is aligned into the pipe and activated to the required pressure.  During this process, the cone of the tool quickly extends allowing the segments to flare swaging the pipe into the pre-machined grooves of the Quickflange connector.  The tooling is then reversed concluding the installation creating the permanent gas tight seal.
