Quickflange is a leading provider of high performance weldless, flange to pipe connection solutions. The patented technology is a permanent solution for improving pipelines integrity and flow assurance to the Oil and Gas industry. Our safe and cost-effective solutions are standard weld neck flanges which are quickly mounted involving no hot work or welding.


Quickflange was developed to support construction, maintenance and modification of new and existing pipework. To date, the weldless connection solutions have been used around the world with over 2,500 applications.

Typical applications include:

  • Replacement of damaged or corroded piping
  • Replacement of existing flanges
  • Insertion of valves and tees
  • Re-routing and de-bottlenecking
  • Pipe work and new spool tie-in
  • Fitting flanges in restricted areas
  • Difficult to weld materials including CuNi, Monel and Duplex


Technical Features

Partnering closely with leading Oil & Gas industry innovator, Det Norske Veritas (DNV), the Quickflange weldless connection has passed vigorous testing and qualification for pressure containment properties and minimal load resistance values.

The range of solutions are constantly evolving with new combinations of pipe diameters, materials and pressure ratings, all in accordance with DNV.

Technical features include:

  • No heat, no spark, no hot work
  • Permanent full-strength connections
  • ASME flange specification range
  • Activated in minutes
  • Light and simple one part design
  • Multiple redundancy metal seals
  • Available in a large variety of materials & diameters
  • Crevice corrosion protection
  • DNV Certified Zone 1 and 2


Results and Benefits

As the flange is slide over the pipe end and activiated with a cold-forging tool, no hot work is required. By avoiding the use of gases, ignition sources and flames traditionally required for welding, ensures increased safety.

The whole connection process takes no more than 15 minutes for the largest size (12”) and less for smaller pipe diameters. Furthermore, the weldless solution uses a modified standard flange which his self-contained meaning it can be shipped and delivered within hours bringing significant time savings.

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.

With simple application and installation, personnel requirements compared with traditional welding techniques, ensures a cost effective weldless pipe connection solution.
