Our safe and cost-effective solutions are standard weld neck flanges which are quickly mounted involving no hot work or welding. The patented technology is a permanent solution for improving pipeline integrity and flow assurance to the Oil & Gas industry.
The mechanically robust weldless flange-to-pipe connection combines a modified standard flange with a hydraulic tool and patented internal groove pattern to the machine in such a way that it slides over the pipe end and is activated with a cold-forging tool.
The two processes generate huge contact pressures, forming a seal and grip on the pipe. No spark or heat is generated and the process secures a metal-to-metal seal with no moving parts, balls, springs or gaskets.
Applications
Quickflange™ was developed to support the construction, maintenance and modification of new and existing pipework. To date, weldless connection solutions have been used worldwide with over 10,000 applications.
Typical Applications include
- Replacement of damaged or corroded piping/existing flanges
- Replacement of Insertion of valves and tees
- Re-routing and de-bottlenecking
- Pipework and new spool tie-ins
- Fitting flanges in restricted areas
- Difficult to weld materials including CuNi, Monel and Duplex

Partnering closely with leading Oil & Gas industry certifying authority, Det Norske Veritas (DNV), the Quickflange™ has passed vigorous testing and qualification for pressure containment properties and high load resistance values. The range of solutions are constantly evolving with new combinations of pipe diameters, materials and pressure ratings.
Technical Features include
- No heat, no spark, no hot work
- Permanent full-strength connections
- Activated in minutes
- Light and simple one-part design
- Crevice corrosion protection
- DNV Certified Installations Zone 1 and 2
RESULTS & BENEFITS
- IMPROVED SAFETY As the flange is slid over the pipe end and activated with a cold-forging tool, no hot work is required. Avoiding the use of gases, ignition sources and flames traditionally required for welding ensures increased safety.
- QUICK The whole connection process takes no more than 15 minutes for the largest size (14”) and less for smaller pipe diameters. Furthermore, Quickflange™ uses a modified standard self-contained flange so it can be shipped and delivered within hours bringing significant time savings.
- FLEXIBLE Installation can take place in contained areas with no impact to production and with a wide range of pipe diameters, this is a fully flexible solution. The Quickflange™ weldless connection is also compatible with numerous materials.
- REDUCED COSTS With simple application and installation, personnel requirements compared with traditional welding techniques, ensures a cost-effective weldless pipe connection solution.
