Acidproof tiles ATM-1

 

            These tiles are made of graphite fiber composite material - antegmit, grade АТМ-1,

conforming to TU 1916-002-5382976-2008 "Lining graphite tile".

            The tile is used for the protection of steel hardware, reinforced concrete structure surfaces, storage facilities operating in liquid aggressive media in the range of temperatures from -20°С to 115°С.

            The sizes of the tiles fabricated are (mm) 125×195×10 and 125×195×20. Tiles of any thickness up to 50 mm as well as smaller sizes are available at Customer's option.
