AL2O3 Wear And Corrosion Resistant Seamless Steel Pipe

AL2O3 wear and corrosion resistant seamless steel pipe consist of three parts (steel pipe + adhesive + ceramic tiles), the steel pipe is made of seamless carbon steel pipe.  Abrasion resistant ceramic tile lined steel pipes are 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.

The pipe welding type ceramic technology of Wear resistant ceramic sheet pipe with holes is mainly used to solve the problem of anti wear of conveying system equipment under high temperature pneumatic force. It has the characteristics of super wear resistance, high temperature resistance, good toughness, strong impact resistance, and stud welding does not fall off.

Physical properties of ceramic tile lined pipe

To achieve the best abrasion-resistant solutions, thicken ceramic liners can be used in the elbow which has serious abrasions.

Our Alumina Ceramic Lined Project has good wear resistance and impact resistance, the use of alumina wear resistant ceramic liner, can help extend the service life of the equipment, thus to reduce unnecessary maintenance costs. Because of its light weight and good welding performance. Therefore, welding, flange, fast connection and other methods can be used to facilitate the construction and installation. Our Alumina Ceramic Lined Project includes ceramic wire tube, elbow, cone, ceramic turret, ceramic-lined hydrocyclone,  valves to help users obtain the maximum efficiency of the equipment.

Ceramic tile lined elbow fabrication technology principle, special corundum ceramics, made from Al2O3 as raw material, with rare metal oxides as solvents, and sintered at high temperature by 1730 ℃, are combined with wear-resistant ceramic pieces and block bricks in the pipe wearing surface through bonding, welding, inlay, riveting and socket technology. Thus forming a surface with excellent abrasion resistance, and the matrix still uses the composite pipe of the ordinary metal material.

According to different needs of the choice of wear-resistant ceramic patches, to meet the special needs of users of technical conditions. Compared with the traditional all-metal high alloy pipe fittings, the working face has higher abrasion resistance, which can make the whole wear-resistant and anticorrosion service life of the pipe increase several times to dozens of times times. Overall weight of the first mate down, reduce the amount of steel, reduce the cost of equipment and maintenance costs, improve economic efficiency.

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.

High hardness
Rockwell hardness of high alumina ceramics is up to HRA80-90 which is second only to diamond and far exceeds wear-resistant steel stainless

Excellent wear resistance
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.

Corrosion resistance
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.

Thermostability
Working temperature of high alumina ceramics can be as high as 1400℃.

Good self-lubricity
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.

Light weight
The density of high alumina ceramics is about 3.6g/cm3, which is only half that of steel, thus easy for construction and installation.

Technology and structure of ceramic tile lined pipe

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.
