Use : Multi-lateral
Tiles : 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. 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.
