Ceramic tile lined pipes are a type of steel pipe that have been lined internally with ceramic tiles to provide superior resistance to wear, abrasion, and corrosion. The ceramic tiles are typically made from high-grade alumina ceramics, which are known for their hardness, strength, and durability.
Ceramic tile lined pipes are commonly used in applications where the pipes are exposed to harsh environments, such as in mining, power generation, and chemical processing. The ceramic lining provides superior wear resistance, protecting the underlying steel pipe from premature failure due to abrasion or corrosion.
In addition to their excellent wear properties, ceramic tile lined pipes may also provide benefits such as reduced friction, improved flow rates, and lower maintenance costs. They may also be used in applications where hygiene is important, as the ceramic lining is non-toxic and does not react with most chemicals.
Ceramic tile lined pipes may be manufactured in various sizes and shapes, including elbows, tees, and reducers, to meet the specific requirements of each application. The ceramic tiles may be bonded to the steel pipe using specialized adhesives, and may be installed using conventional welding techniques.
While ceramic tile lined pipes can offer significant benefits in terms of wear resistance and longevity, they are typically more expensive than traditional steel pipes due to the cost of the ceramic lining and specialized manufacturing processes.
There are many clients who are concerned about the specification of ceramic lined tile sheet, because it is related to whether the ceramic chip purchased can be used.
Wear resistant ceramic lining is AL203 as the main material, with rare metal oxide as solvent, after more than 1700℃ high temperature roasting to special ceramic, embedded into rubber , polyurethane or mild steel for the purpose of low to moderate impact and highly abrasive sliding application.
Main performance indicators: The wear resistance of the ceramic work surface is more than 100 times that of manganese steel, 20 times that of high chromium cast iron, and several times to several dozen times higher than that of wear resistant rubber. Ceramic metal bonding strength up to 300kg/cm2 can be used up to 500°C.
The use of equipment made of wear-resistant ceramics, the service life can be increased by more than five times, and the performance-cost ratio can be increased by more than three times.

Technical Specifications: SunnySteel offers various models of ceramic lined wear-resistant pipes and can also customize production as per requirements. Ceramic lined wear-resistant pipes are essentially not restricted by pipe size, and they can be produced for diameters ranging from 1 inch to 120 inches or even larger.
It is important to note that expansion joints are not limited to ceramic tiles alone. They are also used in other applications, such as in pipework systems and ducts, where ceramic lined pipe expansion joints are designed to absorb dimensional changes caused by heat-induced expansion.
When installing ceramic tiles, it is crucial to consider the proper placement of expansion joints. Guidelines suggest that grout lines must be wide and proportional to the size of the tiles, and expansion joints in the tiling must also be calculated accordingly.
Ceramic tile lined expansion joints are used to accommodate the movement and expansion of ceramic tile surfaces, preventing cracks and damage. They can be installed in various ways, such as creating gaps between tiles or toothed around the tiles in an offset-bond pattern.

Metals have good ductility but poor resistance to abrasion - which means that abrasion prevention is required when metal pipes are used in high-temperature fluid catalyst service. On the other hand, ceramics possess great hardness and abrasion resistance, but they are brittle. Metal Ceramic double pipe is a hybrid pipe using metal as an outer pipe and a ceramic material for inner pipe segments, applied together to utilize the two materials' advantages. Hence excellent wear-resistance and good corrosion resistance of the ceramics and high strength and toughness of metal can be well combined to get a comprehensive advantage of wear-resistance, corrosion-resistance and anti-scaling. They are suitable for applications in heavy wear working conditions.
