Cast basalt composite heavy caliber pipe is a type of pipeline that is used for the transportation of abrasive and corrosive materials. It is made from individual fused cast basalt segments, which are joined together to form a pipe of a specific diameter. This type of pipe has an excellent performance in terms of abrasion and corrosion resistance, making it ideal for conveying material such as slurry, hydraulic fluids, or pneumatic fluids. The nominal diameter of cast basalt composite heavy calibre pipes can range from 40mm to 800mm. These pipes are widely used in various industries, including mining, power generation, and chemical processing, due to their superior wear protection capabilities.

Pipes that last longer

The 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 abrasive, corrosion materials or slurry. We can offer the basalt pipes with nominal diameter of 40mm-800mm.

Other specifications of cast steel pipe lined with basalt can be manufactured according to customer technical requirements. Suitable for large-diameter basalt lining steel pipes with a nominal diameter greater than 800mm. Generally, according to the running status of the pipeline, different cement is used to fix the basalt brick inside the finished steel pipe to complete the basalt lining steel pipe. Its advantages are good wear resistance, wide range of use, basically not limited by the size of the pipeline and low cost of pipeline installation.

Why get your cast basalt pipes from Sunny Steel?

Cast basalt pipe can be divided into straight pipe, elbow, three-way (four-way) pipe and variable diameter pipe, etc.

  • 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.

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.

The excellent performance of cast basalt lined steel pipe is that it sets tenacity of steel pipe, abrasive resistance of cast basalt pipe, concreteness of cement mortar in one.

This greatly improves the products adaptive capacity in complicated operation conditions. At the same time. Cement mortar is selected as the filling material and this can make the inside surface of steel pipe in alkali mediums. So the surface of steel pipe generates purifying films. These films can prevent being rusted.

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.
