Shape Memory Alloy Couplings for pipes - Standard or customized

Typical applications:

  • Welds where X-ray tests would be mandatory, and your production rate or maintenance frequency are so low, that you should re-qualify your operator teams for each new weld.

  • Pipes that are so close to each other, that there is no space for a welding head.

  • Quick repair solution at customer site with limited equipment capacity (military operation theaters, satellite in Launch Vehicle integration site, ...).
  • Pipe diameters that are so small, that (i) there are no longer machines that could do this in a controlled and repetitive manner (ii) X-ray inspection is no longer a reliable way to monitor the result.

  • For joining two pipes, made of different alloys or processes.

Currently, this product in available as 1/4'' and 1/2'' pipe OD versions up to 320bar/4640psi MEOP, but rapid customization is possible, thanks to  in-house, very flexible R&D en Production entities equipped with CAD/CAM, very specific FEA tool, CNC equipment for prototyping and serial production, leak test bench with helium mass spectrometer,  1,300bar/19,000psi high pressure facility and vibration test shaker.

Depending upon Quality and Supply-Chain requirements, specific solutions can be provided.

In addition, ChP Consult can propose a complete solution for pipe kits (Development and Serial production):

  • Co-development of piping solution (including bracket constraints relative to couplings, bi-metal coupling, other component...)
  • Design/adaptation of couplings (material, dimensions, fatigue constraints, ...)
  • Manufacturing according to space quality rules
  • Acceptance test of segments (geometry, tightness, proof, electric continuity...)
  • Shipment
  • ...
