The integral ceramic tube is the ceramic pipe fittings as a whole after firing, with a special filling material will be poured in the steel pipe internal assembly. The pipe wall is smooth, good sealing, with good wear resistance, corrosion resistance.

Abrasion resistant ceramic tile lined steel pipes are composed by steel pipe, adhensive and abrasion-resistant ceramic, we use 20 # seamless steel pipes shaping with hot bending (it is different from centrifugal casting or steel plate rolling), the ceramic tiles bonding with GWJ-350 high temperature-resistant inorganic adhesive which was developed by TsingHua University and to affix abrasion-resistant ceramic in the steel pipes, we use miss match installation instead of directly bonding (this technology was used in the bridge building a thousand years ago), and forms a firm wear-resistance layer after heating solidification. Abrasion resistant ceramic tile lined steel pipes are applicable for the pneumatic powder-feeding, and can be used under a temperature of 350℃without aging and peeling for long life. The service life is 4-5 times than the normal abrasion-resistant pipes.

A high alumina ceramic lined bend is a type of pipe bend that incorporates a lining made of high alumina ceramic material. This lining is designed to provide exceptional wear resistance and protect the bend from abrasion, erosion, and corrosion.

The high alumina ceramic material used in the lining is known for its hardness, strength, and excellent wear resistance properties. It is typically made of alumina (aluminum oxide), which has a high Mohs hardness and is capable of withstanding harsh operating conditions.

The benefits of using a high alumina ceramic lined bend include:

  1. Wear resistance: The high alumina ceramic lining offers superior resistance to abrasion, making it ideal for applications where the pipe bend is exposed to abrasive materials or high-velocity particles.
  2. Corrosion resistance: The ceramic lining provides excellent resistance to chemical corrosion, protecting the pipe bend from degradation caused by corrosive fluids or environments.
  3. Extended lifespan: The high wear resistance properties of the alumina ceramic lining result in a longer service life compared to traditional metallic materials.
  4. Increased efficiency: By reducing the wear and tear on the pipe bend, the high alumina ceramic lining helps to maintain the flow efficiency of the system and minimize downtime for maintenance and replacements.

After the inspection and acceptance by the quality inspector, the construction of the next process can be carried out.
3 Formulated Adhesives It must be measured in strict accordance with the prescribed proportion, and how much should be used; it must be stirred evenly, and the overall mixing should not be less than 4 times; if the mixed embedded material is added, the binder must be mixed well before adding the mixture and mixing Not less than 3 times. Assigned by designated personnel.
4 Repair of the adhesive surface If there are potholes on the pasting surface, especially if there are large potholes on the pasting surface of the old equipment, the wear-resistant ceramic sheet must be gradually filled with embedded materials. After the inspection and acceptance by the quality inspector, the construction of the next process can be carried out.
5 Paste wear-resistant ceramic tiles There should be no dust or dirt on the surface of the ceramic tiles. The surface of the repaired inlay material must be leveled. The pasting surface must be wiped again. Scrape the adhesive on the pasting surface for 1-2 times and scrape it flat. Scrape the back of the ceramic sheet for 1 It is necessary to ensure that there is a certain thickness of uniform adhesive available for pasting. Checked by the person in charge of the construction of the pasted ceramic tiles.

Application area of ceramic tile lined pipes

Application area of ceramic tile lined pipes

The use of Ceramic tile lined pipe and fittings is ideal in services that are prone to erosive wear, and where standard pipe and fittings would fail within 24 months or less.

Ceramics with very low friction factor at low impingement angles decreases the abrasion of materials maximally. Its low density makes it easy to carry and install.

These ceramic lined fittings include elbows, bend, reducers and T pipes are bonded with the abrasion resistant alumina or ZTA ceramic tiles into the inner wall of the carbon steel pipes/elbows with strong-high-temperature resistant adhesive, thus form a firm abrasion resistant layer.

Application area of ceramic tile lined pipes

This method mainly applied in the pneumatic&hydraulic conveying system and it can be applied in almost all kinks of pipe fittings like coal powder conveying pipes and elbows,dusting,ash, slag removing pipes ,elbows,reducer,T pipe and cross pipe, even laterals, mining slurry conveying pipe fittings and so on. Almost no limitation for the the diameter of the pipe fittings.

Easy-Flexible joint connection

A conventional ceramic tip was arranged with a certain gap between tips in a steel pipe so that the pipe was damaged at the gap before the tip was worn out. The newly developed ceramic tip has a shape with no straight line portion parallel to the transport direction so that the steel pipe is protected until the tip is worn out.

The tailings that are in the pipeline hydraulic transport,which are the phenomena known as the wear abrasion,fatigue,impact.

Have seen that,the use of a tube is 6mm in lenght,the pipe wall thickness was 20mm,and after 8 mounths of using,the bottom is correded till the pipe has 1mm of thickness.

The pipe lined by Dahua has the advantage of the 3mm to 4mm of thickness after 12 mounth of use.

The direction of alignment of ceramics in zig zag,have excellent resistance tc friction of abrasive agents such as sand,gravel,gravel,tailings with solid particles,scale,coal,pulp, tailings from phosphate,salt slag, sludge,ash,..

The perfect choice Resistance to abrasion is superior to all material available on the market

The ceramic alumina pressure has superior performance against abrasion,wich has five times more resistant than the conventional ceramic. If the objective is protection of components and reduced maintenance costs,the correct application of anti-abrasive lining led immediately to track the economy. If the objective is protection of components and reduced maintenance costs,the correct application of anti-abrasive lining led imediately to track the economy.

The ceramic pipe lining of hydraulic and pneumatic conveying transport has efficiency and economy,especially in steel tubes.Where they have great advantages, increasing the time of life.

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.

Ceramics are among the hardest materials available and provide ultimate wear resistance in piping. In high wear applications, ceramic lined pipes have been demonstrated to be cost-effective by increasing service life and reducing maintenance costs. Sunny Steel supply ceramic lined abrasion resistant steel pipes to your custom dimensions and budget. Our ceramic linings are the highest quality materials available to ensure that we provide the most cost-effective solutions for our clients.
