Characteristics and production technology of ceramic tile lined pipe

Ceramic tile lined pipe using ceramic-metal composite production technology principle, with Al2O3 as raw material.

Ceramic tile lined pipe process welding sturcture

Special Corundum ceramics made of rare metal oxides as solvents and sintered at high temperature by 1730 ℃ through bonding, welding, mosaic, riveting and socket technology, a variety of wear-resistant ceramic pieces, block brick materials in the pipe wear surface, so as to form a surface with excellent wear resistance, and the matrix is still using the composite pipe of ordinary metal.

According to different needs of the choice of wear-resistant ceramic patches, to meet the special needs of users of technical conditions. Compared with the traditional all-metal high alloy pipe fittings, the working face has higher abrasion resistance, which can make the whole wear-resistant and anticorrosion service life of the pipe increase several times to dozens of times times. Overall weight of the first mate down, reduce the amount of steel, reduce the cost of equipment and maintenance costs, improve economic efficiency.

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.
Basalt and alumina ceramic are the two generally accepted lining materials. Other linings which complement the basalt and ceramic include Eucor, AZS, silicon nitride bonded silicon carbide, and ceramic filled epoxy coatings.

Main properties of ceramic tile lined pipe

Ceramic tile lined pipe wear good: wear-resistant ceramic pipe lining ceramic layer for wear-resistant engineering ceramics, its hardness (HRA) ≥84, its wear resistance is high chromium wear-resistant cast iron alloy pipe fittings more than 10 times times. The use of 5mm thick ceramic layer, its actual wear-resistant life will be equivalent to 50mm thick wear-resistant cast steel.
Ceramic patch Composite pipe corrosion resistance: the use of different wear-resistant ceramic materials, for different corrosive medium has excellent anti-corrosion properties, acid, alkali, salt and other strong corrosive medium and brine corrosion characteristics.
Ceramic tile lined pipe high temperature performance: wear-resistant ceramic itself with 1200 degrees Celsius above the high-temperature capacity, through reasonable design and use of different composite methods, wear-resistant ceramic pipe fittings can be in-50 ℃ to 800 ℃ humidity range of long-term operation, especially for high-temperature burners and other equipment lining.
Ceramic tile lined pipe to reduce project cost: wear-resistant ceramic pipe is mainly used for conveying particles of liquid-solid two-phase flow and corrosive media, for the replacement of expensive stainless steel tubes, high chromium cast steel pipe, carbide wear-resistant pipe, can directly reduce the project cost, while prolonging the service life. Products cost-effective, can save maintenance, replacement material costs and time.
Ceramic Patch Composite pipe is our company to draw on the domestic and foreign advanced technology of similar products developed on the basis of a shell for steel, wear-resistant ceramic tube of new composite pipe products, with high wear resistance, long service life and so on.

Characteristics of ceramic tile lined pipe

The use of anti-fall porcelain tube, porcelain pipe inlay, so that the paste more flat, more solid.
The use of strong inorganic adhesive paste, wear-resistant steel bowl welding, porcelain tube and steel combined to form a double reinforcement to ensure that the porcelain tube does not fall off.
The surface of the porcelain tube is smooth, the running resistance is small, the scaling is unfavorable.
Flexible installation, high abrasion resistance, convenient processing and moderate cost.

Production process of ceramic tile lined pipe

Steel body Grinding-> Ceramic patch-> Paste-> Welding-> Detection
Use tools to clean the surface of the steel body.
The raw material can be mixed evenly before use.
The ceramic tube is pasted by professionals to ensure that the porcelain tube is free from the wrong side and the surface of the ceramic pipe is smooth.
After testing qualified storage.
Wear resistant ceramic pieces of the fixed way

Wear-resistant ceramic pieces of the fixed way at present only three kinds of bonding, welding and docking. Here is a detailed description of these three fixed ways.

Adhesive is the current wear-resistant ceramic pieces of the most fixed application of a way, as long as the wear-resistant ceramic glue selection of suitable surface treatment can be very good fixed ceramic, and construction efficiency is very high. His deficiency is not resistant to high temperature, in the impact of a relatively large situation can not guarantee stability.

Welding is a good way to deal with the high-temperature impact of a fixed method, he used the first sticky after the welding method, with the help of solder joints can not be able to handle the high temperature and impact conditions, but the corresponding construction efficiency will be greatly discounted.

The application of the plug is relatively small, because it requires special wear-resistant ceramic pieces, such ceramic pieces are difficult to make, the relative price will be relatively high, but in some cases can only be used in this way.

What is the temperature of the wear-resistant tube 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.
