Cast blast lined pipe and fittings

Cast blast lined pipe and fittings is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

Cast Basalt is a mineral of exceptionally high abrasion resistance, unlimited resistance to moisture, high compressive strength and resistance to virtually all acids and alkalis and is completely corrosion free. Cast blast is produced by melting selected natural basalt broken into sizes of 20-50 mm in shaft furnaces at temperatures around 1,300C, following by casting at which the melted basalt forms uniforms pherolithic crystals hence producing its typical physical properties, in particular its exceptional hardness and wear-resistance.
Cast basalt reaches a value of hardness of 8(min) on the Moh’s hardness scale. For comparison: the highest value10is only attained by diamonds. By virtue of these properties, the silicate cast basalt provides outstanding protection against abrasion and scrubbing.
However, it is marked by ascertain sensitivity to impacts. Under Normal services conditions, cast basalt withstands temperatures up to approx. + 350C or-40C. However Cast basalt should not be subjected to temperature shocks.
Sizes: Cast basalt produces are manufactured as tiles, from pieces and segments. Straight pipes are spun-cast, available for nominal bores of 32 to 600 mm with the wall thickness ranging from 20 to 30mm and a standard length of 500mm.samller nominal bores of straight pipes, pipe segment for radial of 40 to 3,000mm of various angles, as well as special form piece linings are predominantly sand-cast. The standard wall-thickness is 20mm. depending on the respective quantity, steel moulds can also be used, the wall thickness in those cases usually being 30 to 40mm.
Advantages
Fused cast basalt surfaces remain smooth and low in friction when used over time, thereby offering the benefit of low caking.
Fused cast basalt provides excellent protection against the following abrasive media: ore - sinter - ash - slag - sand - coal - clinker.
