Tube, pipe, fittings and flanges
Recuperator tubes in a wide range of high-temperature corrosion resistant materials suitable for flue gas temperatures up to 1300ºC (2370ºF).
The Alleima portfolio covers materials for most types of recuperators used for heat recovery in, for example, steel and metal processing, glass production and carbon black production.
The Alleima portfolio includes several materials allowing for higher operating temperature, enabling increased heat recovery and higher efficiency. Examples are Kanthal APMT and Alleima® 253 MA*.
