Quickflange Weldless Connectors

Revolutionise Your Pipeline with Quickflange, No Hot Work Required

Robust pipe to flange connections without welding. Provides installation of permanent and gas-tight flange connections quickly and cost-effectively. Best suited for petrochemicals, energy, oil and gas industrial pipelines that require no hot work.

Increase Pipeline Installation Speed and Safety with Quickflange

Quickflange is a test and proven method for more than 20 years across various industries. This technology ensures quick and safe installations eliminating hot work and it is the mechanically robust alternative to traditional welding. Added benefit of corrosion protection on crevices. Wellube provides Quickflange service across UAE, Qatar and India, in partnership with ICR, a UK-based specialist on asset integrity.

Our Quickflange connector, paired with a bespoke activation tool, ensures seamless installation. With patented internal grooves, it effortlessly slides over pipe ends, facilitating swift and precise connections. The process is streamlined: after isolating the line and achieving a straight cut, the Quickflange aligns flush with the pipe edge. Our hydraulic tool, meticulously calibrated, swiftly activates to the required pressure, seamlessly swaging the pipe into the grooves for a permanent, gas-tight seal.
