Product Description
Ceramic-lined steel pipe and elbow are mainly used in parts prone to erosion and wear, which can reduce pipe wear and increase equipment service life. They are mainly used to transport highly abrasive materials, such as quartz, sand, ash, clinker, coal, powder, etc. The use of a ceramic-lined steel pipe and elbow is the most effective way to repair severely worn pipes.

Alumina material and type
Ceramic-lined steel pipe and elbow material: mainly 92% and 95% alumina ceramics, 97%, 99%, and ZTA ceramics are also available.
Alumina ceramic types include:
1. Types include flat plate, orifice welded plate, slotted plate, mutual pressure plate, dovetail groove, trapezoidal plate, curved plate, inner and outer arc plate, big and small head plate, imported alumina powder ceramic lining plate for cyclone, trapezoidal Ceramics, cylindrical ceramics, ceramic mosaics, etc.
2. Ceramic thickness between 3mm and 60 mm.
The advantages of Ceramic Lined Steel Pipe And Elbow are as follows:
1. It is difficult for corundum ceramics to react chemically with other substances, so it can transport corrosive substances;
2. Corundum ceramics have high hardness and wear resistance, and can transport materials with high impact and corrosion;
3. The surface of corundum ceramics is relatively smooth, the material is not easy to accumulate, the resistance is small, and it is not easy to block the material;
4. The density of corundum ceramics is only half that of steel, and the weight is lighter under the same thickness, which is convenient for transportation and installation;
5. The development of ceramic composite pipes is more and more comprehensive, and the market is also more and more extensive. It is not only used in the electric power industry, but also in the port, metallurgy, coal, petroleum, chemical, building materials, machinery, and other industries. It is a wear-resistant pipe with very high-cost performance.
Product Composition
Ceramic lined steel pipe and elbow are composed of three parts: steel pipe layer, adhesive layer, and alumina ceramic layer from outside to inside. The steel pipe layer is usually made of stainless steel 304 or Q235 integral seamless carbon steel pipe, the viscose filling layer is made of high-strength inorganic viscose, and the ceramic lining layer is made of 92% or 95% alumina ceramic lining.
Ceramic pipes are mainly used to solve the severe wear of powder and slurry conveying systems. We can provide customized ceramic-lined steel pipes and elbows according to the different requirements of customers.
The production process of ceramic tile-lined pipe
The installation of wear-resistant porcelain tiles includes steps such as grinding, glue adjustment, glue application, ceramic bonding, trimming, and inspection. It should be noted that in the process of glue adjustment, the glue should be adjusted according to the proportion of ceramic pasting glue, and it needs to be adjusted in half. Use it up within an hour to prevent the adjusted glue from being left for too long and solidifying, and cannot be applied to ceramics and equipment.
What are the technical specifications for wear-resistant ceramic construction?
The construction of wear-resistant ceramics will have different processes for different equipment, different industries, and different working conditions. Let's take a look with us below.
1. Before construction, the surface of the equipment needs to be polished and dusted. When there is a lot of dust, it is necessary to use a cleaning agent to clean the polished part;
2. Attention should be paid to the blending of the adhesive. The ratio should be adjusted according to the ratio of the glue. After the ratio is mixed, the glue should be mixed repeatedly. After the adjustment, the glue is easy to solidify, so try to use it up within 30 minutes, and you can take a small amount many times. Adjust the glue in a way to avoid waste;
3. When applying glue, it is necessary to apply glue to the polished part first, and also apply glue to the bottom of each piece of porcelain and the four sides of the porcelain;
4. When installing the ceramics on the polished part, it is necessary to pay attention to extruding the ceramic block to ensure that the glue at the bottom is evenly dispersed after being squeezed, and then the porcelain needs to be pressed tightly to reduce the gap; After mastering the above process requirements and standards, and following the correct steps for construction, the ceramic installation can be firm and beautiful.
