Cast Basalt Pipe

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...

Cast basalt pipe adopts foam packaging, then in accordance with the specifications to put them into wooden cases, sometimes they can be directly loaded into the compartment or container.

Basalt cast stone tube is produced from basalt, through crushing, melting, centrifugal casting, annealing and quality control. Wear and corrosion resistance, acid and alkali resistance, with small resistance coefficient and water absorption close to zero. Widely used in mines, thermal power plants, coal mines, steel mills and other material delivery pipeline, cost-effective, service life can be extended.

More than twice as strong as natural basalt, our cast basalt has been used successfully in heavy industrial applications for over 20 years. Basalt casting was originally developed in the China to be used as a replacement to iron and steel which was in short supply after WWII – the crushed natural basalt is heated back to molten lava and then poured into moulds to make components such as pipes and floor tiles, which are incredibly hard wearing and abrasion resistant. Cast basalt can be formed into a diverse range of shapes and surface patterns –  including bespoke designs (min 325m2). During the cooling process the surface of the material achieves a glass-like patina, with an iridescence and texture that is unique to each piece.
