Cast stone wear-resistant pipe

What is a basalt pipe? excellent hard-wearing surface

Basalt pipe is a natural mineral material that provides an excellent hard-wearing surface for corrosive wear and abrasion of equipment. We use a basalt lining to significantly increase the service life of our pipes, saving you money.

Cast basalt is a mineral material which, thanks to its special characteristics, is superbly suitable as wear protection.

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.

A basalt pipe has a stronger strength as compared with that of a bare pipe. Its external effect of strength is higher than the raw form. Another important feature of cast basalt is that it is resistant to chemicals including alkalis and acids.

Basalt-lined pipes

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. According to customer requirements along with cast basalt production technology and we can offer various specifications and various shape to meet client’s need.

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

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.

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.

Why get your cast basalt pipes from Sunny Steel?

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

Design Aspects

The bend radius should be minimum 3 times of nominal bore

At discharge end of each bend, cast basalt lined straight pipe of length 5 to 12 times the nominal bore must be used.
