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.

The length of the straight anti-wear shields ranges from 20mm to 3000mm, and the general length of 1000-2000mm is commonly used. The anti-wear shields with bends generally requires a processing drawing and the following parameters should be on the drawing: outer diameter of the pipe used, bending of the pipe Radius R (to the center of the pipe), the degree of bending angle, and the length of the straight sections on both sides of the arc segment of the wear-resistant shields.

“snap-on” type shield

The most basic parameter of boiler tubes shields is the outer diameter of the tube used (that is, the inner diameter of boiler tubes erosion shields). The main specifications of the tube are: 32, 38, 42, 44.5, 48, 51, 57, 60, 63.5 , 76, 89mm, etc . the inner diameter of the boiler tubes erosion shields is usually 1-3mm larger than the outer diameter of the tube used, depending on the actual requirements.

Tube shields production process

To ensure the accuracy of the material. Positive Material Identification (PMI) of stainless steel sheets for tube shields is critical to verifying the grade and composition of stainless steel before it goes into production.
Tube shields from us are manufactured to exacting standards. Advanced equipment and material handling capabilities permit us to offer the fastest turnaround times anywhere.
The current production process for tube shields is to use high-pressure presses and professional moulds for pressing.
The production time is short, the welding performance is good, the welding seam does not fall off, the surface is smooth and the appearance is beautiful. The arc-shaped wear-resistant tile is pressed on a press or bent on a pipe bender with a special mould.
