Product Description
Cast basalt pipe shields 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 pipe shield 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.

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

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.
