High performance weldless flange to pipe connections
For over 20 years, Quickflange™ has revolutionised flange-to-pipe connections by providing a permanent and mechanically robust alternative to traditional welding. Our technology ensures rapid and safe installations eliminating hot work providing a cost-effective solution for improving pipeline integrity and flow assurance.
Technology Overview
ICR’s Quickflange™ weldless technology utilises a modified standard flange where patented internal grooves are machined in such a way that it slides over the pipe end. By combining our Quickflange™ connector with our bespoke Quickflange activation tool, the process of installing a Quickflange weldless connector is both quick and easy.
Installation made easy
Upon isolating the line and ensuring a straight cut is achieved to the pipe, Quickflange™ sits flush to the pipe edge. Our hydraulic tool is aligned into the pipe and activated to the required pressure. The tool’s quick extension flares the segments, swaging the pipe into the pre-machined grooves of the Quickflange™ connector. A simple reversal of the tool concludes the installation, creating a permanent gas-tight seal.
Varied product range
Our connectors cater to a wide range of pipe sizes, pressure classes, and – most crucially – material types that can be challenging for traditional welding methods.
Size Range: ¾” to 14”
Material Range: Carbon Steel, Stainless 316, Duplex, Super Duplex, 6Mo, Copper-Nickel & Nickel Alloy.

Confined Spaces
Quickflange™ is ideal where welding habits or welding in general would not be possible
Remote Locations by Rope Access
Our tooling can be rigged into position or handheld to easily reach remote locations. We can also train 3rd party personnel in the installation process.
Piping Repairs
Quickflange™ is an ideal option for repairing pipework permanently – saving on average 80% time over welding.
Close Proximity to Heat Affected Zones
Quickflange™ can be installed as close to 20mm from the heat-affected zone of a weld.
Hydrocarbon Gas and Liquid Systems
Quickflange™ is type-approved for use on hydrocarbon gas and liquid services with a proven track record over 2 decades.
Pipework Modifications
Whether an asset or site requires modifications, a new spool tie-in or a system needs to be rerouted, Quickflange™ is an ideal solution where hot work is not always a safe, cost or time-effective option.
Pipework Construction
Multiple Quickflange™ installations can be carried out in the same shift – maximising productivity – ideal for system replacements/construction where time is limited.
Decommissioning
Quickflange™ is an ideal option to cut and blind off lines no longer in use.
