Mersen’s cladding technology, CL-Clad®, is a process in which a thin layer of reactive metal (tantalum) can be cladded onto a carbon steel or stainless-steel base plate. CL-Clad® technology is suitable for large thicknesses when design pressure is high.

The CL-Clad® process offers:

  • Excellent resistance to thermal and mechanical shocks
  • A full vacuum resistance
  • Superior corrosion resistance against most process fluids.

Brazing is the assembling of metals through capillary action. A filler material, with a melting point below that of the other base metals, is added. The metals are then heated to enable the filler material to melt and spread between the metals to form a perfect joint.
