Cast basalt half pipes have an excellent performance of high abrasive and high corrosion resistance. Cast basalt is a mineral material produced by melting natural basalt at a temperature of approximately 1300°C, followed by casting into moulds. This contributes to its superb physical and chemical properties.
Cast basalt half pipe is a common component of the heating part of tubes. It is usually used in power station boilers.The useful life of tube shield is 3-5years. The tube shield has a variety of material and the selection of the material shall be subject to the original design of the boiler.The tube shield is divided into straight pipe and bend pipe. The main effect of tube shield is to protect the pipe and increase the service life of the pipe.
Cast basalt pipe shields are designed to eliminate major maintenance and downtime costs from boiler and condenser tube failure.
We offer cast basalt tiles for coal bunkers and chutes. These cast basalt tiles are bedded as well as jointed in cement/special bonding agents like resins depending upon application. These tiles mostly find application in automotive industry and are designed to provide long-lasting lining and enhancement to involved operational life cycle for both plant as well as equipment.

Advantages:
* Utilizing Cast Basalt enhances and improves operational life of
plants.
* These are best suited for jobs where extensive cutting is needed.
* We can also deliver pre-cut tailored tiles based on the
considerations of vibration, impact and other factors at client’s
end.

Combined with the cast basalt production technology. We can manufacture cast basalt tiles according to various sizes and shapes.
Ultra-thin cast slate: the thinnest 12mm
The self-developed ultra-thin Cast basalt tile is a new product of the international advanced level.
Cast basalt pipe shield 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.
Coal drop bucket lining
lined with cast slate, generally 25-30mm (high chromium steel is best used for coal drop points);
