Linings made of Cast Basalt are proven to last six to ten times longer than steel, cast iron, Ni-hard, etc. These products are known for their sturdy constructions and dimensional accuracy.

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


  • Nominal Bore: 32 to 600 mm
  • Wall Thickness: 20 to 30 mm
  • Length: 500mm


  • 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 to 500NB.
  • Temperature – Cast Basalt withstands temperature up to 4500 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 are cast basalt lined pipes so wear-resistant

The moulding process of cast basalt lined pipe includes solution casting, sintering and thermal direct sintering. So, why the cast basalt lined pipe is very wear-resistant cast basalt lined pipe has been widely used in building materials, chemical industry, metallurgy, mining and other industries. Cast basalt lined pipe is an ideal substitute material for steel, iron, lead, rubber, wood, etc. In some parts of many equipment. Individual metals cannot achieve high wear resistance, acid and alkali corrosion resistance, and have the advantages of extending equipment service life, reducing maintenance man-hours, improving production efficiency, and reducing product costs.

The cast basalt lined pipe has the characteristics of thoughtful structure, low water absorption, high compressive strength and good wear resistance. Except hot phosphoric acid, hydrofluoric acid and dissolved alkali above 30℃, it has good corrosion resistance to almost all inorganic acids, organic acids, alkalis, salts, water and organic solvents. The brittle material of cast stone has high hardness, and the problem of cast stone is that it is brittle and is not easily impacted by heavy objects.

Under the microscope, the cast stone can be seen interlaced with individual pyroxene spheres or feather-like crystallites of 0.05-0.1 mm. The thoughtfulness of this internal structure greatly improves the hardness of the cast stone, and its mohs hardness reaches 7~8. The greater the hardness of the material, the better the wear resistance. From the point of view of atomic and molecular structure, the combination of silicon and oxygen atoms of this silicate mineral is connected with each other by a strong force.

Individual cast basalt lined pipes have good wear resistance in blast furnace tank utilization, and meet application requirements in terms of wear resistance, but there are also brittleness of ceramic materials, which are easily broken during the process of falling ore. The construction of single-piece pasting is incomplete, and signs of aging will appear after a long time of pasting. The wear-resistant material not only has good wear resistance in the use of blast furnace tanks, but also meets the application requirements in terms of wear resistance, and has a mortar material, which is tough and will not be smashed in the process of falling ore. Good performance, combined with cement, not limited by time and so on. The wear resistance of cast basalt lined pipes is also the reason for their widespread use.


Cast basalt pipeline transportation on the apllied site
Cast basalt pipeline transportation to the applied site

Cast basalt pipes owing to an excellent performance of abrasive and corrosion resistance .It may be used as the liner of pipeline for hydraulic,pneumatic of conveyance of material and corrosion materials or slurry.We can offer the basalt pipes with nominal diameter of 40mm-800mm.

Cast Basalt can be used for the lining of pipework, chutes, bunkers, cyclones, and hoppers. It has become the global standard in areas such as ash slurry pipework, often used at fossil-fuel power stations. It is an all-round cost-effective and adaptable lining material that extends the life of equipment in the pipe or tile form where affected by erosion.

Cast Basalt is well-proven in a variety of industries as a cost-effective, long-lasting lining material used to extend the operating life of equipment manufactured or lined with lower-wearing materials such as steel, cast iron, rubber, and polyurethane.

Cast basalt lined steel pipe, as both a wear—resistant and corrosion—resistant materials, the transport properties of wear or corrosion of materials, after thirty years of practical verification, cast basalt lined steel pipe can be well done.

Installation site

Cast basalt is also used in cement plants for making air separators, chain conveyor, silica hoppers, nozzles, coal hoppers, cement hoppers, cyclones, raw mill ducts, chutes, thick slurry lines, mixers, grate cooler housing, coal ventury etc.

Cast basalt lined pipes and fittings can be supplied with different and connections as per the design requirement to suit the site conditions and easy installation.

Flange Connection

As a standard production, we supply flanged components according to DIN, with at least one movable flange for easy mounting, but pipes with plain ends or for custom coupling are also available. Flange Connection Is One Kind Of Common Pipeline Installation Connections. By Two Pieces Of Flanges, Pipeline, Valve, Equipments Are Connected And It Forms A Tight Piping System. When Pipeline Pressure Is Larger, Flange Connection Is Priority Selection. Flanges Have Lots Of Different Sizes. Flange Size Is Determined According To Pipeline Normal Diameter And Pipeline Operation Pressure.

The parameters of the outside steel pipe will be decided according to the working pressure of the system. The connection of the pipes and fitting will be of flange connections, easy—flexible joint connection or by welding.

Welding & Beveled End

It suits short Distance Pipeline System Without Maintenance. It Is One Kind Of Common Installation Connections. It Requires Installation Personnel Higher Welding Ability. It Also Restricts By Welding Site, Distance, Welding Positions. Welding Connections Is Inconvenient In Later Maintenance.

Easy-Flexible Joint Connection

It Is One Of High Efficient And Rapid Installation Connection. I T Has The Below Characteristic: Easily Install And Disassemble, Fast Installation, Temperature Adjustable Compensation Function, Saving The Necessary Expansion In Long Pipeline. Easy-Flexible Joint Also Has Angle Compensation Characteristic. At Smaller Angle Turning Points, Easy-Flexible Joint Can Be Instead Of Bends And Adjust Angle.

Design aspects

1. The bend radius should be minimum 3 times of the nominal bore.

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