Anti-Wear Cast Stone Lined Steel Pipe
Anti-wear cast stone lined steel pipe / cast basalt lining composite tube have an excellent performance of abrasive resistant and corrosion resistant, can be used as the pipeline lining in conveying wearable materials and corrosion materials.
The combination of high rigidity of cast basalt ceramic and high elasticity of steel gives the pipe unmatchable features as an abrasion resistant, heat resistant and corrosion resistant material used in the variety of industries.Such as: electric power plant, chemical plant, metallurgy industry, mine and so on. Cast basalt pipe can be divided into straight pipe, elbow, three-way (four-way) pipe and variable diameter pipe, etc.
Advantages
Good abrasion resistance
As the wear surface, the cast basalt ceramic is 8 Mohs hardness, whose wear resistance is 10 times that of hi-chrome cast iron alloy pipes. It can make little wear loss of the pipe during running, which extend the service life of the equipment largely.
Good thermal stability and excellent corrosion resistance
-50-350 ℃ is ideal temperature for the cast basalt ceramic lined pipe, and the inner wall of the pipe is cast basalt plates or tubes which have unique chemical properties of wonderful acid and alkali resistance.
Light Weight
The density is 3.63g/cm³, which is only half of the steel to reduce the load of equipment largely.
Easy and fast to fix on site
Welding, flange, flexible joint are available for fix with the equipment.
All the performance of Anti-wear cast stone lined steel pipe / cast basalt lining composite tube makes low project costs, the charges can be about 20-30% less than wear steel piping project.
Normal Specification
Full range of Anti-wear cast stone lined steel pipe / cast basalt lining composite tube including straight pipes, bends, elbows, tees,Y-pieces, reducers,crosses and etc can be available from our factory.
Regarding the connection ways, we can provide with the normal way of welding or flange or to customize according to the customer’s requirements.

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.

Ceramic lined equipment and bends
Hard & Compact Smooth & Inner Withstands High-Abrasion & Corrosion In any of the process industries especially Sled and Cement corrosion and abrasion lead to significant downtime of the plant. Further, the useful life or the equipment itself may get impaired because of the high abrasive nature of the materials being used. Thus, ‘wear mechanism’ results in hut down, replacement, etc., which is costly, resulting in loss to tilt: tunic of millions of dollars.
Characteristics
- High resistance to all types of chemicals.
- High resistant to sliding abrasion.
- Non weld ability & smooth surface results ill easy How of materials.
- Can With stand and temperature up to 200 C.
- Smooth Surface and resistant to abrasion & corrosion.
Technical details:
- 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 a perpendicular angle is low like all other ceramics, but it can be increased with proper installation by reducing the angle of impact. Cast Basalt can be used to mitigate sliding abrasion. 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 approximately 90 kg/sq. m; whereas bends and pipes are lined using Basalt Cylinders of various standard sizes from 50NB up to 500NB.
- Temperature: Cast Basalt withstands temperature up to 450ºC.
- 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.
