Advantages and disadvantages of bonded and welded ...

The two commonly used methods of installing wear-resistant ceramic lining in wear-resistant ceramic pipeline are direct bonding and welding. Both can improve the service life of the pipeline and protect the inner wall steel parts from direct impact wear and corrosion of materials, but the two are different in terms of cost, process and use effect. Now let's understand the advantages and disadvantages of bonded ceramic lining and welded ceramic lining in wear-resistant ceramic pipeline.

The advantages of bonded wear-resistant ceramic lining are that the construction cost is relatively low and the process is relatively simple. It can be installed in small pipes with a diameter of about 108mm. Even equipment with a slightly complex internal structure can be installed with bonded wear-resistant ceramic; The disadvantage of stick-type wear-resistant ceramic lining is that the connection between ceramics and equipment mainly depends on ceramic adhesive. Even the high-temperature resistant adhesive has a temperature resistance of about 220 ℃. If it exceeds this temperature, the ceramic may fall off when the material is impacted, so it is not suitable for application in areas with high temperature and strong impact.

Adhesive wear-resistant ceramic lining

The advantage of the welded wear-resistant ceramic lining is that it can be fixed by the combination of welding and inorganic adhesive, and can operate normally for a long time at a high temperature of about 700 ℃. Moreover, because the fixation is more firm, it can be used in the equipment or parts with high impact such as high-speed running machines and other moving parts. The wear-resistant effect and impact resistance effect are relatively better; The disadvantages of welded wear-resistant ceramic lining are relatively high construction cost, complex process and high labor cost. The length and width of porcelain chips are generally more than 100 * 50, and welding equipment is required, which cannot be used in pipes with small diameter.

Welded wear-resistant ceramic lining

Stick-type wear-resistant ceramic lining and weld-type wear-resistant ceramic lining have their own advantages and disadvantages, which need to be selected according to actual working conditions.
