Corrosion Resistant Materials

World n°1 in graphite anticorrosion equipment

The Anticorrosion and Process Equipment Activity missions consist in designing innovative solutions for its customers in the following environments:

  • high temperature;
  • corrosion.

Mersen’s engineers design and manufacture solutions based on a unique combination of material and know-how.

Today, our customers acknowledge our expertise in improving their industrial performance in many fields.


Mersen, expert in graphite for more than 120 years, designs and manufactures graphite equipment for the circulation, the heat transfert and the storage of highly corrosive fluids.

Graphilor® is a Mersen trademark material made of isostatic graphite combined with a choice of various impregnations.


Mersen’s R&D engineers have extended their expertise to reactive metals. Tantalum is welded by TIG. Extreme care is required to ensure that all surfaces, which due to the heat of welding reach temperatures above 300°C, are shielded with inert gas.


Armylor®, the PTFE coated pipe range, is the result of decades of R&D, combining processes and materials innovations to address the chemical and pharmaceutical industries.

This equipment fulfills our customers’ demands thanks to our experience and skills in thermal design, process engineering and anticorrosion materials. 




Mersen offers a range of 3 Graphilor® 3, based on various impregnations (phenolic, carbon and PTFE) which ensure the imperviousness, the resistance to corrosion and temperature as well as the long-term stability.
