Cast Basalt Pipe

Basalt is a volcanic rock possessing ideal properties like inertness coupled with excellent resistance to corrosion and abrasion.
After selective quarrying the rock is melted at a temperature of around 1500 degree C and cast into molds or spun into cylinders. The castings so produced are then subjected to heat treatment cycles in special kilns to produce re-crystallized basalt. The product thus produced inherits inertness of parent materials. Its microcrystalline, non-porous texture being denser and more homogenous than raw basalt, it acquires exceptionally high abrasion resistance.
