Ceramic tile lined pipe refers to a type of steel pipe that is lined with ceramic tiles to provide increased wear resistance and protection against abrasion and corrosion. Welding wear-resistant ceramic pipes is to stick the alumina ceramic lining tile with holes in the middle of the inner wall of the pipe with strong adhesive, and at the same time, with the spot welding process, the ceramic liner plate is firmly welded to the inner wall of the steel pipe through the small holes.
The specifications for ceramic tile lined tiles
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.
Process flow of Ceramic tile lined pipe
The ceramic tile is pasted on the steel pipe with high temperature wear-resistant glue to play a wear-resistant role, and the pipe is generally white. Generally used for large diameter pipes.

Features
The Rockwell hardness of the ceramic tile is HRA80-90, the hardness is second only to diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel.
Its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.
The density of the ceramic tile is 3.5g/cm3, which is only half of that of steel, which can greatly reduce the load of the equipment.
The wear-resistant ceramic tile is pasted on the inner wall of the device with heat-resistant super glue. It can run for a long time at 350°C without aging, and the inorganic adhesive used for cemented products can withstand a temperature of 750°C. The temperature resistance and adhesion performance of the adhesive are far ahead in China.
The toughening formula of ceramics can form strong crystal bonding bonds, which greatly enhances the impact resistance of alumina ceramics.
According to our customer follow-up survey for more than ten years, under the same working conditions, the service life of the equipment can be extended by at least ten times.

Composition of ceramic tile lined pipe
Composition | Thickness | Material | Process characteristics |
---|---|---|---|
Steel | 6-16mm | 20# seamless pipe Stainless pipe | Steel pipes with High strength and smooth interior |
Viscose | 0.5-1mm | High temperature resistant inorganic compounds | Long-term operation under high temperature of 350 °C without aging, thermal expansion, strong adhesion |
Ceramic tiles | 5-25mm | Corundum with a Al2O3 content is more than 92% | High density, super wear resistance, good toughness |
Technology and structure of ceramic tile lined pipe
Ceramic tile lined pipe is composed of three layers: outer steel pipe layer, corundum layer, and ceramic glue layer. The inner ceramic layer is white from the surface. The ceramic is generally 95% ceramic, and the temperature is generally below 200°C .
At present, the common ceramic sheets lined with ceramic composite pipes are: ceramic block, dovetail mutual pressure, welding type, mosaic, card slot and so on.It has the characteristics of wear resistance and long service life.

Why Do I Need Wear Parts?
“Wear” is the last thing any business wants to experience with their machines. Apart from its unpleasant physicality, it could also be a sign that means your parts and/or components are about to break. You need wear parts to help prevent or prolong the wearing out of these parts and components – and that could be any type of wear parts such as pipes, liners, plates, etc.What Kinds of Wear Plates Do You Offer?
Here at Sunny Steel, we put emphasis to the primary kinds and types of wear pipes and fittings – they include:- Ceramic Liner pipes and fittings
