Description
Basalt cast stone lining steel pipe is consist of steel pipe, basalt cast stone pipe and the concreteness of cement mortar.
Basalt Cast Stone Lining Steel Pipe is made with lining basalt cast stone pipes, steel pipe and the cement mortar filling between the two layers, it brings the wear resistance and corrosion resistance of cast stone pipe. And it improves the product's ability of adapting various complicated working condition. Using cement mortar as filling material, can make the pipe inner surface in alkaline medium, so that prevent corrosion.
Advantage
1. wear resistant : As the wear surface, the hardness of cast basalt is 8 Mohs, whose wear resistance is 8 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.
2. corrosion resistant: Cast Basalt is almost absolutely acid/alkali resistant (except Hydrofluoric Acid) and hence corrosion resistant.
3. against high pressure: 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.
4. Easy to transport:The density is 3.0 g/cm³,which is only half of the steel to reduce the load of equipment largely.
5.Low Price:The price is 1/2 of alumina ceramic lined steel pipe.
The basalt pipe is a reliable and effective combination of wear—resistant materials. Be used in a variety of transportation of corrosive materials in working condition.
Application
Wear Resistant Cast Basalt Stone Lined Steel Pipe / Elbow is widely used for serious abrasive environments, such as chute liners, cyclone liners, conveyor skirt liners, processing piping liners, hopper or silo liners, screen equipment liners in the industries including ,but not limited to:
1.Coal Preparation Plants
2.Coal Fired Power Stations
3. Mineral Processing Plants
4. Cement Plants
5. Chemical Plants
6. Steel & Iron Plants
7. Railway Stations
8. Ports

Comparision
Comparison of Ceramic lining with few other materials under standard conditions :
| Material | Thickness(mm) | Approx life (months) |
| Mild Steel | 10 | 3-5 |
| Cast Iron | 20 | 6-8 |
| Ni-Hard | 20 | 12-14 |
| Cast Basalt | 30 | 25-20 |
| Ceramic | 10 | 30-40 |
Packaging and shipping of basalt cast stone products
basalt Cast stone pipes are formed by centrifugal casting of rock slurry, annealed out by tunnel kiln, and need to be stored in the open air for a period of time to naturally eliminate the residual internal stress of the cast stone pipes. The cast stone pipes are shipped in foam packaging, and then packed into wooden crates according to the matching specifications, or sometimes directly into carriages or containers.
