Alumina Ceramic Mosaic Lined  Wear-Resistant Composite Pipe

Our ceramic composite wear-resistant pipe is designed according to the customer's requirement of steel pipe (Q235), the thickness of ceramic lining, and the inner diameter size of the final pipe. We use a special ceramic adhesion agent to laminate 92% pure alumina ceramic products to the inner wall of the steel pipe, thus forming a hard wear-resistant layer.

Features:

1. Good wear resistance

The lining layer of the wear-resistant pipe is alumina ceramic, with Rockwell hardness up to 90 (HRA90 or more), which has high wear resistance to abrasive media delivered by metallurgy, electric power, mining, coal mining and other industries, and its life is more than ten times that of the quenching platform.

2. Anti-corrosion and anti-scaling 

Since the ceramic layer is alumina ceramic, it has acid and alkali resistance, corrosion resistance and anti-scaling properties.

3. Good resistance to high temperature and thermal shock

It can be used in the range of -50℃ to 900℃ for a long time, and the coefficient of linear expansion is 6-8×10-6/℃, which is about 1/2 of steel pipe.

4. Easy installation and construction

Because of its small weight and good welding performance, it can be easily installed by welding and flange connection.

The composite wear-resistant pipes produced by our company have long life and high quality. It is widely used in metallurgy, iron and steel, coal, mining, thermal power, cement, chemical and other industries with serious equipment wear.

Application

Metallurgical and electric power industries consume a large amount of metal pipes every year to transport pulverized coal, ash, mud, lime gypsum slurry, etc. The use of ceramic lined composite pipes to replace other pipes has the characteristics of high wear resistance, long service life, convenient installation and significant economic benefits.

Power plant: Alumina Ceramic Mosaic Lined Pipe is used in coal-fired power plants for ash removal, slag discharge pipes, powder feeding, powder returning pipes, and desulfurization pipes.

Metal mines:  Conveying wear-resistant elbows for concentrates and tailings;

Metallurgy:  Blast furnace coal injection and slag conveying pipes for iron making in iron and steel plants; CAO, zinc and sand conveying pipes, ferroalloy conveying in steel making, out-of-furnace refining and other preferred wear-resistant elbows;

Cement plant:  Raw slurry transportation, pulverized coal transportation, hoist unloading, finished cement pneumatic transportation loading and unloading of rotary kiln wet production line, concrete transportation wear-resistant elbow.

Chemical plant:  Coal powder conveying pipeline, silicon powder and other raw material conveying wear-resistant elbows.

Mine:  Mine filling, concentrate powder and tailings transportation have serious wear and tear on the pipeline. The service life of the ore powder transportation pipeline used in the past, such as Daye Mine, is less than one year. Changing to this pipe can increase the service life by about 5 times.

Coal:  Coal preparation and long-distance pipeline coal transportation generally adopt wet transportation, which requires the transportation pipe to be both wear-resistant and corrosion-resistant.
