Typical applications

Basalt is ideally suited to protect equipment where abrasive materials are conveyed and cause sliding abrasion such as in pipes and bends for pneumatic or hydraulic systems, in cyclones and seperators, in flumes and chain conveyors, in hoppers and silos, mixers, tanks, pulpers, etc.

What is Cast Basalt?

Naturally occuring basalt rock is quarried, melted, cast and annealed to form a finely crystallised glass, ceramic of extreme hardness (8.5 on the moh scale)

What is it for?

Basalt provides a long lasting lining for static plant over which large volumes or abrasive and/or corrosive materials are passed.

How is it fixed?

Basalt tiles can be bedded and joined in cement or special bonding agents. The agents chosen depend on the application. Tiles can be supplied with a counter sunk central hole for individual bolting onto or in ready-made liner plates and pipes.

Where is it used?

Basalt can resist wear, corrosion and temperatures up to approximately 400 °C; Cast Basalt is generally used in wet material handling situations such as coal chutes and ash sluceways, ash pipelines at power stations and hydraulic granulated slag or sand conveying services . Basalt should be used in light impact areas. If you are in doubt let our sales engineer advise you on an “impact friendly” design.

Other than automobiles, some of the other industries where these are used in include:

  • Power
  • Coal
  • Steel
  • Cement
  • Pulp & Paper
  • Mineral Processing

Cast basalt tiles is mainly used in thermal power plants, steel mills, mines and other parts with heavy wear, such as raw coal bunkers, mine bins, coal unloading trenches, hoppers, ore troughs, flotation machines, chutes and other parts.

  • Round coal bunker lining: ultra-thin cast slate 14-20mm thick;
  • Coal discharge ditch lining: commonly used 25-30mm thick cast slate;

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 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.


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.
