Mersen Piping Systems and accessories


Mersen offers a full range of PTFE / PFA lined pipes and accessories specially designed to convey corrosive fluids for the chemical and pharmaceutical industries. Using Armylor®, Mersen’s proprietary PTFE / PFA material, our products are corrosion resistant at any temperature or pressure conditions.

Due to our more than 50 years of experience with lining technologies, Mersen has gained the ability to optimized our products and limit the permeability rate. Our knowledge allows us to understand the chemical nature, temperature, and pressure of the process, and the importance of the lining thickness, to provide the low level of permeability required.  


Mersen thoroughly tests the mechanical and physical properties of each batch of material manufactured. Multiple internal audits, dimensional and visual inspections, and thorough tests are done during the entire manufacturing process. Data, such as elongation at break point and tensile strength, is collected and evaluated in order to guarantee the product delivers a low level of permeability.
