Abrasion resistant ceramic lined pipe, Abrasion Resistant Lined Pipe and Elbow, Wear Resistant Alumina Ceramic Cone

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.

Application Guidance

Wearable ceramic lined pipe

Wearable ceramic lined pipe includes straight pipe, bend, reducer,transition short sections and so on.Ceramic-metal composit technique is adopted for these. All kinds of ceramic tiles are used as linings in the inside worn surfaces of pipeline by adhension, welding, inlay, reveting and socket. And the excellent wearble inside surface is achieved. The substrate of pipeline is also adopted the common metal materials. Compared to the traditional all metal high alloy of pipeline, the work surface has higher abrasive resistance.

The whole pipeline of useful life in abrasive resistance aspect and corrosion resistance aspect is improved more than dozens of times. And the whole weights are decreased,amount of steel pipes which are sued are decreased.These points bring lower products price, maintenance cost and improve the economic returns.

Alumina Ceramic – Abrasion Resistant Linings

Alumina is a cost effective and widely used material in the family of engineered ceramics. Alumina ceramics have been developed and optimized for maximum wear resistance and corrosion resistance. A high density, diamond like hardness, fine grain structured and superior mechanical strength are the unique properties that make it the material of choice for a wide range of demanding applications.

Alumina Ceramic has uses similar to cast basalt but it has greater resistance to wear in high velocity applications and impact resistance in extreme dynamic systems.

Sunny Steel provides its customers with the full range of abrasion resistant lined pipe work including straight pipe, bends and elbows, reducers, tees and y-pieces. Sunny Steel offers a comprehensive range of lining materials designed to combat erosion.

耐磨管的温度是什么with ceramic patch technology? How about the paste strength?

As a result of the use of paste technology, the main use of high-temperature, high-strength adhesives for pasting ceramic patches, and most of the use of high polymer adhesive temperature is not higher than 200 degrees, and the higher the temperature, adhesive strength is lower, aging speed also increased rapidly.

Therefore, the use of paste ceramic technology, the workpiece temperature is generally not higher than 150 ℃, under this temperature, the general ceramic and metal paste strength can reach 200 kg/cm. For higher than this temperature components, can be used ceramic composite wear-resistant process treatment, so that the use of temperature can reach 500 or more than 700 degrees.

Why Ceramic Coating?

The abrasion pipe of thermal power plant is mainly conveying raw coal powder, ash slag, flue gas desulfurization (FGD) limestone powder and slurry, due to the transmission of medium velocity fast, poor operating conditions, resulting in pipelines, especially elbow, variable diameter pipe serious wear and corrosion, not only consumes a lot of metal materials, but also to the thermal power plant security, economic operation has brought hidden dangers. The abrasion mechanism of pipeline is mainly based on erosion wear. Wear-resistant pipe can be divided into two categories: single metal pipe and composite pipe.

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.

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.

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,..

We are sure that from pure-hearted cooperation we can establish good relationships. Feel free to contact us, we are sure to satisfy you with our professional information, top quality products, best price, and efficient services.

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.

金属具有良好的延性,但可怜的阻力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.
