Cast Basalt

Floors of interiors, specially historical buildings, hotel halls, restaurants, motor shows, very mechanically loaded floors of industrial buildings including exteriors; floors resistant to chemical agents, oil products etc. Cast basalt pipes suitable for hydraulic and pneumatic stowing and in general for transport of variety of abrasive materials. Special castings (bends, branch pipes, T-sections, Y-sections as additions of piping orders, grate rolls, jets, cyclones etc.) as replacement of parts of high-alloy steel. In general we can say that casted basalt has 5-20 higher abrasion resistance than special alloyed cast iron and steel.

Chemical Resistance – Cast Basalt is almost absolutely acid/alkali resistant (except Hydrofluoric Acid) and hence corrosion resistant.
Temparature – Cast Basalt withstands temperature up to 450 C.
Life – Life of basalt-lined pipe is estimated to be 7 to 10 times that of Cast Iron, and 3 to 4 times that of Ni-hard Steel.
