What working conditions are ceramic tile lined elbows suitable for?

The pulverized coal conveying and dedusting system pipelines are used to convey high-temperature gas mixed with hard particles. Its operating characteristics are high temperature, high flow rate, high particle hardness, and serious equipment wear. Especially the elbow part of the pipe, because the airflow changes the flow direction at the elbow, the material directly washes on the outer inner wall of the elbow, which causes serious wear to the elbow. If no protective measures are taken, it is usually worn out in less than a year. Most of these equipments are mounted on high-altitude supports, which are inconvenient for maintenance. Once worn out, the safe use of the equipment will be seriously affected.

Wear-resistant ceramic tile lined elbows. According to different porcelain types and processes, it can be divided into arched patch type ceramic elbows, stud welding type ceramic elbows, and integrally formed wear-resistant ceramic elbows. According to the different working conditions of users, the Special Ceramics designs different types of wear-resistant ceramic elbows, and the operating temperature range: -50°C – 750°C.

• Wear resistance: high-quality alumina corundum ceramics are used, and the hardness is above HRA85, which is more than 10 times wear-resistant than ordinary pipes;
• High temperature resistance: it can operate at a high temperature of up to 750 °C;
• Anti-seismic and thermal expansion and contraction: the thermal expansion coefficient of viscose is between steel and ceramics, which can well adjust the extrusion of ceramics due to the inconsistent thermal expansion of ceramics and steel; at the same time, a variety of flexible fibers are added to viscose, To maximize the guarantee that the ceramics will not fall off during long-term operation under the environment of vibration, frequent thermal expansion and cold contraction;
• Erosion resistance: It can resist the erosion of larger particle materials without breaking;
• The inner and outer walls are smooth and the air flow is smooth: the smooth surface allows the material to pass freely without hanging and blocking;
• Easy to install: 1/3 lighter than ordinary pipes, easy to handle, save manpower, easier and faster to install, and can easily erect pipes higher;
• Low cost: reduce the load of support and hanger equipment and save material cost;
• Reduced maintenance: Excellent wear resistance greatly reduces the frequency of maintenance, saving costs and labor.
