Equipment from reactive metals for the chemical / pharmaceutical industries

Mersen designs and manufactures equipment (columns, pressure vessels, reactors, heat exchangers) using reactive metals suited to meeting the extreme conditions associated with industrial chemicals and pharmaceuticals processes.


Reactive metals

For decades, Mersen has developed a specific know-how in the treatment, design and manufacture of corrosion resistant equipment from reactive metals like tantalum. Mersen provides any design, including solid, lined and cladded construction.


CL-Clad® is Mersen patented cladding technology. In this process, a thin layer of reactive metal (tantalum) can be cladded onto a carbon steel or stainless steel base plate.

CL-Clad® technology is perfectly suitable for large thickness when design pressure is high.
This process offers an excellent resistance to thermal and mechanical shocks, a full vacuum resistance and a superior corrosion resistance against most process fluids.


Assembling metals through capillary action.

A filler material with a melting point below that of the other base metals is added to them. They are then heated to enable the filler metal to melt and spread between the metals to be assembled in order to form a perfect joint.
