Bending Ceramic Sleeve Lined Pipe One Piece Alumina Ceramic Tube

Product Description

The one-piece ceramic tube is also called the one-piece ceramic tube, which is assembled by firing the wear-resistant ceramic tube as a whole and pouring it into the steel tube with special fillers. The pipeline has a smooth inner wall, good airtightness, good abrasion resistance, and corrosion resistance, and the ceramic ring has the characteristics of a smooth inner wall and super abrasion resistance. It is widely used in the chemical industry, fine powder transportation pipeline,  and other industries, with high wear resistance and anti-corrosion functions.

When transporting abrasive materials in the pipeline (such as ash, coal powder, slag powder, tailings, cement, etc.), there is a problem of rapid wear of the pipeline, especially the rapid wear of the elbow. When the gas, liquid, or solid with strong corrosion is transported in the pipeline, there is a problem that the pipeline is corroded and quickly damaged. Since the alumina-lined ceramic tube is integrally formed, the slurry cannot be penetrated. At the same time, the alumina ceramic tube has high hardness. The isostatic pressing dry powder molding process is very beneficial to the uniformity of the ceramic crystal structure. Performance is better than wear-resistant ceramic sheets of the same material.

According to the traditional process, the production of ceramic rings mainly adopts techniques such as hot die casting, grouting, and isostatic pressing. The isostatically formed ceramic ring has better compactness and more precise ceramic dimensions.

Product Features

Wear resistance: under the same conditions, it is 10 times more wear-resistant than ordinary pipes;

High-temperature resistance: it can run at 750℃ for a long time, which can meet most working conditions;

Corrosion resistance: One piece ceramic tube and inorganic adhesive can resist acid and alkali corrosion;

Erosion resistance: it can resist the erosion of larger particles;

Smooth inner wall: The smooth surface allows materials to pass freely without material hanging and blocking;

Reduce maintenance: super abrasion resistance greatly reduces the frequency of maintenance, saving costs and labor

Technical requirements for ceramic pipe wear-resistant elbow

1. The elbow is required to be lined with a ring-shaped ceramic tube, a ceramic wear-resistant layer greater than or equal to 10mm, and an outer shell steel pipe greater than or equal to 5mm. The ceramic should be filled with the same thickness of ring-shaped ceramic between each section of the pipe to ensure firm bonding and No trace of the transition.

2. Alumina content ≥95%, density ≥3.65g/cm3, Rockwell hardness ≥82 HRA, compressive strength ≥850 Mpa, fracture toughness KΙC≥4.8MPa·m1/2, bending strength ≥290MPa.

3. The wear-resistant elbow has a smooth transition, a smooth surface, and a height difference of <1mm. The bending angle deviation is ±0.3°. And has good thermal stability to ensure long-term normal operation.

4. The size of the elbow is made according to the technical requirements of the drawings.

The production process

The integral wear-resistant ceramic pipeline is composed of a steel pipe layer, a viscose filling layer, and a ceramic anti-wear layer from the outside to the inside.

Steel pipe layer: The elbow is formed by SUS304 or Q235 as a whole. Compared with the welded elbow, it has a beautiful appearance, smooth airflow, and stronger pressure resistance.

Adhesive layer: Adopt special ceramic viscose, strong shearing force (15MPa), and good workability.

Ceramic layer: The arc is customized according to the radius of curvature of the elbow, and the end and end of each section of the ceramic pipe are connected by sockets.

Product application areas

It can be widely used in mining, electric power, metallurgy, coal, chemical industry, and other industries as the conveying of abrasive particles and corrosive media such as sand, coal, ash, aluminum liquid and so on.
