ISO Ceramic Sleeve Lined Pipe Custome Pneumatic Conveying Pipeline Lined With Ceramic

Product Description

The pneumatic conveying pipeline lined with ceramic is composed of three layers of steel, viscose, and ceramic. The steel part adopts 304 stainless steel pipe or carbon steel pipe, and the ceramic is bonded to the inner wall of the steel by high-strength adhesive. After heating and curing, a strong wear-resistant layer is formed, which will not age or fall off after long-term operation in an environment below 150 °C. Its life is more than 4-5 times that of ordinary pipes.

The main reason for the wear of the pneumatic conveying pipeline is that the pneumatic conveying device transmits the conveyed material through the air during the conveying process, and the air needs to exchange momentum when stirring the material. To prevent the material from staying in the pipeline, the material must maintain a certain speed of movement. During the conveying process, there is collision and impact between the medium and the pipe wall, which is the principle of wear of the conveying pipe in the pneumatic conveying device. Straight pipe sections in pneumatic conveying pipelines are lightly worn. The easy-to-wear parts mainly occur at the bends of the pipes, especially the outside of the bends of the pipes that are impacted by solid particles. The pneumatic conveying pipeline lined with ceramic is widely used in the anti-wear of the inner wall of the pipeline, especially the elbow.

Causes of pipe wear

1. Wear caused by material impacting or rubbing against the inner wall of the tube:

Physical properties of conveyed materials include particle size and shape, concentration, hardness, moisture, breakage rate, and adhesion, etc.

Condition of the conveying pipe including the material and metal composition of the conveying pipe, hardness, surface processing, inner diameter, arrangement and shape, etc.

Conveying conditions include: conveying air velocity, material-to-gas ratio, temperature and flow state, etc.

2. The effect of conveying air velocity on wear:

In pneumatic conveying, the amount of wear can be roughly considered proportional to the third power of the conveying air velocity. That is, the greater the relative velocity of the material in contact with the pipe wall, the greater the contact pressure formed. The higher the frequency of contact produced, the faster the wall of the elbow will wear.

3. Impact angle on wear

The impact angle of the material impacting the pipe wall also has a great influence on the wear of the pipe wall. The material collides with the elbow in the form of a jet at the elbow. The greater the flow rate, the greater the incident angle, which will cause serious wear to the local pipeline and form pits. After long-term operation, it will cause the pipe wall to wear.

4. Influence of material properties on wear of elbows

The larger the particle diameter of the material, the more wear and tear; the more the hardness and concentration of the material increase, the more the wear is aggravated. When the water content of the material increases within a certain limit, the faster the iron and steel material oxidizes, the wear will be aggravated: but if the water content exceeds this limit, the mechanical wear will be reduced, and the wear will be reduced. The greater the contact stress, the greater the wear in general.

5. The influence of the structure and shape of the elbow on the wear

The material flows along the outer inner wall of the elbow. The larger the radius of curvature, the closer it is to a straight tube, and the smaller the corresponding wear and pressure loss. Therefore, the pneumatic conveying system initially used long-radius elbows. In general, the larger the curvature radius of the long-radius elbows, the more serious the impact. The more impact collision points, the greater the energy loss and the more serious the wear. The greater the roughness of the elbow, the greater the frictional resistance, and the easier the elbow is to wear. Usually, the material with less roughness is selected at the elbow. The more elbows are used, the more energy is consumed, the easier it is for pipes to clog, and the faster the elbows wear. The smaller the pipe diameter, the greater the airflow resistance and the more serious the damage to the pipe wall. The greater the bending angle, the greater the amount of wear.
