What is cast basalt pipe?

Cast basalt pipe has good corrosion resistance and wear resistance. Cast stone pipe products are widely used in electric power, coal, mining, metallurgy, chemical industry, construction and other industrial departments of serious wear and corrosion. The service life of parts or equipment can be extended. Cast basalt pipe has excellent corrosion resistance and wear resistance, so it can be used as the lining of all kinds of pipes, chute, funnel, silo, all kinds of dust remover and all kinds of transporter. And all kinds of chemical plants and inner containers or storage rooms for picking corrosive substances. According to customer requirements, we can provide a variety of specifications, various shapes to meet the needs of customers.

A cast basalt pipe is made by a volcanic rock, which is cast in a similar method to that of cast iron. After annealing, it forms a re-crystallized black ceramic of extreme hardness and abrasion resistance. In addition, it will withstand temperatures of up to 350º Fahrenheit.

Cast basalt have an excellent performance of high abrasive and high corrosion resistance. Cast basalt products mainly include cast basalt tile, cast basalt pipe, cast basalt lined steel pipe, clamp cast basalt pipe, cast basalt wear-resistant slip joints, cast basalt wear-resistant valves, cast basalt powder and various wear-resistant corrosion-resistant cement which use cast basalt powder as raw material. Cast basalt products have been widely used in industrial sectors which have serious wear and corrosion of parts and equipment, such as electric power, mining, metallurgy, coal, chemicals, construction and so on. Cast basalt is an indispensable non-metallic industrial new material in the development of modern industry.

Friction Resistance – As more material is passed over Cast Basalt it gets polished up thereby reducing friction further. Cast Basalt improves in service after getting polished. Wetting also improves its performance in practical applications.

Impact Resistance – Direct Impact Resistance at 90 degree is low like all other ceramics, but it can be increased with proper installation by reducing the angle of impact. Cast Basalt is the best wherever sliding abrasion exists. Moreover, external impact strength of composite basalt pipe (enclosed in M.S. Shell) is always more than that of bare Ni-hard Pipe.

Chemical Resistance Cast Basalt is almost absolutely acid/alkali resistant (except Hydrofluoric Acid) and hence corrosion resistant.
Weight and Sizes – Basalt Tiles are available in regular shape square of 200 x 200 x 30 mm thick, weighing approx. 90 kg/sq m; whereas bends and pipes are lined using Basalt

Cylinders of various standard sizes from 50NB upto 500NB.
Temperature – Cast Basalt withstands temperature up to 450 o 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.

Why get your cast basalt pipe from Sunny Steel?

  • Exceptionally high abrasion-resistance
  • Unlimited resistance to moisture
  • High compressive strength
  • Resistance to virtually all acids and alkalis
  • Completely corrosion-proof

The right material for the job

  • Basalt is substantially more erosion-resistant than iron or steel.
  • In fact, over time, as the pipe experiences more friction from the media being transported, the coefficient of friction increases—creating even more beneficial flow outcomes.

A range of sizes for the perfect fit

Straight pipe lengths come in diameters from 50mm to 700mm, and 500mm in length.

It is also possible to line lobster back bends with bend diameters ranging from 50mm to 700mm. The thickness of the basalt depends on the diameter. It ranges from 20mm to 25mm.

Ready for anything

Basalt-lined pipes are perfect for many applications including slurry lines for all mineral processing and hydraulic conveying. They’re commonly used for fine material conveying.

Cast basalt is an all-round cost-effective and adaptable lining material that extends the life of equipment.
