Product Description

The application of alumina ceramics in deslaggers has many important aspects:
 
Advantages of material properties
 
- High wear - resistance: Alumina ceramics have high hardness and can effectively resist the erosion and wear caused by impurity particles during the deslagging process. For example, in the deslaggers of the paper - making industry, sand, gravel, fibers, etc. in the pulp will rub against the inner wall of the deslagger. The alumina ceramic material can greatly extend the service life of the deslagger and reduce the cost and time required for frequent replacement or maintenance of the equipment due to wear.
- Corrosion - resistance: It has good chemical stability and can resist the corrosion of acids, alkalis, and a variety of chemical substances. When dealing with pulps or fluids containing corrosive components, it can maintain structural and performance stability. For instance, in deslagging in the chemical industry, some acid - base solutions or corrosive pulps would easily corrode ordinary materials, but alumina ceramics can work properly.
- Smooth inner wall: An inner wall with extremely low roughness, such as a mirror - like roughness, can be obtained through specific processes. This can reduce the flow resistance of the fluid, making the flow of pulp, etc. smoother inside the deslagger, reducing the risk of blockage, improving the deslagging efficiency, and also reducing power consumption and saving energy.
 
Applications in deslaggers of different industries
 
- Paper - making industry: It is used to make the key cone components of conical deslaggers. Its high wear - and - corrosion - resistance and low - friction smooth inner wall enable it to have a normal operating life of 7 - 9 years. It plays a key role in coordinating the service life of various components in the deslagging system, stabilizing work efficiency, and reducing power energy consumption. Wear is mainly caused by the scouring, cutting, and friction of slag particles, the corrosion of pulp, and fatigue, etc., and mostly occurs at the grain boundaries of the glassy phase and at the pores with stress - concentration phenomena.

Transport and installation precautions:

Matters needing attention for transportation and installation of ceramic pipe
1. The ceramic composite pipe has high hardness and good toughness, but it should be put gently in the process of transportation and installation to avoid serious collision, especially to avoid direct contact with metal instruments or impact on the ceramic layer on the end surface.

2. The qijing bending pipe is installed with directivity. When the bending pipe is installed, the direction indicated by the arrow on the surface of the bending pipe should be consistent with the flow direction of the conveying medium.

3. When installing the pipe, the pipe should be aligned with the center line and level should be adjusted to make sure that both ends meet accurately.The displacement of both ends should be controlled within 1.0mm.

4. When the flexible pipe joint is used to connect and install the pipe, the inserted lengths of both ends of the flexible pipe joint shall be adjusted symmetrically.Since the thermal expansion coefficient of the composite pipe is about 1/3 of that of steel, the expansion clearance can be reduced by 3-5mm.

5. When using flange connection, the flange end shall be flush with the end of the composite pipe.

6. Due to the excellent welding performance of the composite pipe, the pipe connection can be conducted by welding. However, when welding, 45o-60o "V" type slope Angle is 2-4mm and gap is 0.8-1.2mm.
