Download PDFThe combination of high rigidity of ceramic and high elasticity of steel gives the pipe unmatchable features as an abrasion resistant, heat resistant and corrosion resistant material for use in the fields of power generation, metallurgy, mining, and chemical industry etc.. It has many advantages over steel pipes, cast stone pipes, and steel-plastic compound pipes.

The Ceramic tile lined pipe spool is composed by steel pipe, adhensive and abrasion-resistant ceramic, we use 20 # seamless steel pipes shaping with hot bending (it is different from centrifugal casting or steel plate rolling), the ceramic tiles bonding with GWJ-350 high temperature-resistant inorganic adhesive which was developed by TsingHua University and affix abrasion-resistant ceramic in the steel pipes, we use miss match installation instead of directly bonding (this technology was used in the bridge building a thousand years ago), and forms a firm wear-resistance layer after heating solidification. Ceramic tile lined pipe spool is applicable for the pneumatic powder-feeding, and can be used under a temperature of 350℃without aging and peeling for long life. The service life is 4-5 times than the normal abrasion-resistant pipes.
Alumina ceramic-lined bend pipes are engineered to transport pulverized coal powder efficiently. The integration of high-hardness alumina ceramics with durable steel provides exceptional wear resistance, heat resistance, and corrosion resistance, making them ideal for industries such as power generation, metallurgy, mining, and chemicals.
Our alumina ceramic lined project consists of alumina ceramic tiles affixed to a natural rubber base mold with high tensile strength, securely mounted on a steel plate.
These ceramic-lined products serve as cost-effective alternatives to expensive materials such as stainless steel, titanium, nickel, cast stone, or alloy tools. The unique combination of the high rigidity of ceramics and the elasticity of steel results in a heat-resistant and corrosion-resistant material, making it widely applicable in various industries, including power generation, metallurgy, mining, and the chemical industry.
Ceramic tile lined pipe is our company to absorb similar products at home and abroad on the basis of advanced technology developed a shell for the steel body, within the wear-resistant ceramic tube of the new composite pipe products, with high wear resistance long service life and so on.
The use of anti-off porcelain tube, porcelain tube mosaic, so that paste more flat, more solid with a strong inorganic adhesive paste, wear-resistant steel bowl welding, porcelain and steel body combined to form a double reinforcement to ensure that the porcelain tube does not fall off. The installation of flexible, high wear resistance, processing convenience, the cost is moderate.
Rockwell hardness of high alumina ceramics is up to HRA80-90 which is second only to diamond and far exceeds wear-resistant steel stainless
The wear resistance of high alumina ceramics is 266 times that of manganese steel and 171.5 times that of high chromium cast iron. According to our investigation & follow-up to the clients, the service life of equipment can be prolonged over 10 times under the same working conditions.
High alumina ceramics are inorganic oxides with extremely stable molecular structure and no electrochemical corrosion, thus they can resist erosion of acid, alkali, salt solutions and organic Solvents.
Working temperature of high alumina ceramics can be as high as 1400℃.
High alumina ceramics have the properties of self-lubricity and in adhesion, the roughness is only 1/6 that of steel pipes thus less flow Resistance.
The density of high alumina ceramics is about 3.6g/cm3, which is only half that of steel, thus easy for construction and installation.
Ceramic tile lined pipe is composed of three layers: outer steel pipe layer, corundum layer, and ceramic glue layer. The inner ceramic layer is white from the surface. The ceramic is generally 95% ceramic, and the temperature is generally below 200°C.
At present, the common ceramic sheets lined with ceramic composite pipes are: ceramic block, dovetail mutual pressure, welding type, mosaic, card slot and so on. It has the characteristics of wear resistance and long service life.
The ceramic tile is pasted on the steel pipe with high temperature wear-resistant glue to play a wear-resistant role, and the pipe is generally white. Generally used for large diameter pipes.
Bends and other profile sections can be clad in whole and this process has changed the traditional practice to fabricate bend and other profile sections by drawing polyline without changing flow pattern of material inside piping, greatly reducing conveyance resistance of material.
The ceramic tiles are pasted to the inner wall of the steel pipe with high temperature wear-resistant glue to play a wear-resistant role.
| No. | Process | Standard | Inspection |
|---|---|---|---|
| 1 | Cleaning the inner surface of the fitting | Clean up all the rubbish and floating ash on the inner surface of construction equipment and pipe fittings. | Checked by the construction supervisor. |
| 2 | Rust removal, oil removal, paint removal | The rust, grease, and paint on the bonding surface must be completely removed without leaving any traces. Use iron sand skin, angle grinder, and soft sand skin to polish to see the metallic luster. After cleaning, wipe the surface with a cloth until there is no trace of dirt. | After the inspection and acceptance by the quality inspector, the construction of the next process can be carried out. |
| 3 | Formulated Adhesives | It must be measured in strict accordance with the prescribed proportion, and how much should be used; it must be stirred evenly, and the overall mixing should not be less than 4 times; if the mixed embedded material is added, the binder must be mixed well before adding the mixture and mixing Not less than 3 times. | Assigned by designated personnel. |
| 4 | Repair of the adhesive surface | If there are potholes on the pasting surface, especially if there are large potholes on the pasting surface of the old equipment, the wear-resistant ceramic sheet must be gradually filled with embedded materials. | After the inspection and acceptance by the quality inspector, the construction of the next process can be carried out. |
| 5 | Paste wear-resistant ceramic tiles | There should be no dust or dirt on the surface of the ceramic tiles. The surface of the repaired inlay material must be leveled. The pasting surface must be wiped again. Scrape the adhesive on the pasting surface for 1-2 times and scrape it flat. Scrape the back of the ceramic sheet for 1 It is necessary to ensure that there is a certain thickness of uniform adhesive available for pasting. | Checked by the person in charge of the construction of the pasted ceramic tiles. |
| 6 | Repair of gaps and corners between ceramic tiles | The gaps exceeding 3 mm must be repaired with wear-resistant and anti-corrosion fillers, the edges and corners must be neat, and the bevels must be trimmed with special ceramic tiles and then filled with fillers. | After the repair, the person in charge of the construction and the quality inspector will conduct a comprehensive quality inspection, and submit it to Party A for acceptance after passing the inspection. |
| 7 | Maintenance time | After construction and repair are completed, it can be put into use after natural maintenance for more than 12 hours after acceptance by Party A. |
There are probably hundreds of different methods for packing a abrasion resistant pipe and Elbows, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.
