Ceramic rubber Wear Liner

Ceramic-Rubber compound lining plate is compounded by high alumina ceramics and excellent natural rubber through special process. The excellent damping performance of natural rubber greatly lowers the noise generated in the transportation, which fully settled a series of issues such as impact, abrasion and noise.
Features for this kind wear resistant lining:
1) Outstanding wear-resistant performance: the working face of ceramic-rubber compound lining plate is high alumina ceramics, the hardness of which is second to diamond, so it has excellent wear-resistance.
2) Optimum impact resistance: Compared with ordinary ceramic tiles, the Ceramic-rubber plate under the special process treatment changes the ceramic mechanism of easy breakage. With the characteristic of shock absorption of natural rubber, the impact-resistant performance of ceramic will be highly improved which is more than 10 times of ordinary ceramic tiles.
3) Effective noise reduction: excellent damping of natural rubber absorbs a great deal of vibration energy during shocking, and the flexible molecular chain within the natural rubber will be beneficial for damping, which greatly reduces the noise in transportation. Laboratory test indicates the value of noise reduction up to over 30dB.
4) Adjustable specification: the thickness of rubber and ceramic, the shape of ceramic-rubber plate can be adjusted accordingly to fit for the various conveying equipments.

The Type Of Alumina Ceramics

Alumina ceramics are divided into two types: high purity and common type.

Al2O3 content of high purity alumina ceramics is 99. More than 9% of the ceramic material, due to the sintering temperature up to 1650-1990 ℃, the transmission wavelength of 1 ~ 6 microns, usually made from molten glass to replace platinum crucible; It is used as the sodium lamp tube with its transmittance and alkali resistance. In the electronics industry, it can be used as integrated circuit board and high frequency insulation material.

Ordinary alumina ceramics are divided into 99 porcelain, 95 porcelain, 90 porcelain and 85 porcelain in accordance with Al2O3 content. Sometimes the content of Al2O3 is in 80% or 75% of the ceramic series. Among them, 99 alumina ceramic materials are used to make high temperature crucible, furnace tube and special wear-resisting material such as ceramic bearing, ceramic seal and water valve, etc. Alumina porcelain is mainly used as corrosion resistant and wear-resisting parts; In China, due to the constant incorporation of the sliding stone, the electrical performance and mechanical strength can be improved with metal sealing, such as molybdenum, niobium and tantalum, and some used as vacuum devices.

Cast basalt lined steel pipe

Cast basalt lined steel pipe

After 30 years of practical use proved cast basalt lined steel pipe is a reliable and effective combination of wear—resistant materials. Be used in a variety of transportation of corrosive materials in working condition.

Cast basalt lined steel pipe is consist of steel pipe, cast basalt pipe and the concreteness of cement mortar.

The excellent performance of cast basalt lined steel pipe is that it sets tenacity of steel pipe, abrasive resistance of cast basalt pipe, concreteness of cement mortar in one.

This greatly improves the products adaptive capacity in complicated operation conditions. At the same time. cement mortar is selected as the filling material and this can make the inside surface of steel pipe in alkali mediums. So the surface of steel pipe generates purifying films. These films can prevent being rusted.

The parameters of the outside steel pipe will be decided according to the working pressure of the system.

The connection of the pipes and fitting will be of flange connections, easy—flexible joint connection or by welding.

Cast basalt lined steel pipe, as both a wear—resistant and corrosion—resistant materials, the transport properties of wear or corrosion of materials, after thirty years of practical verification, cast basalt lined steel pipe can be well done.

Flange connection is one kind of common pipeline installation connections. By two pieces of flanges,pipeline,valve,equipments are connected and it forms a tight piping system. When pipeline pressure is larger, flange connection is priority secection. Flanges have lots of differents sizes. Flange size is determined according to pipeline normal diameter and pipeline operation pressure.

Abrasion resistant pipe specification, Standard and identification

Because the outer surface behaves like mild steel, the product can be cut and welded with proper procedure in the field, configured into a variety of fittings, and can accept the standard end options of flanges, weld rings and couplings.

Application of Abrasion resistant pipe

Abrasion resistant pipe applied in coal-fired power plant ash and slag discharge tube, powder, powder tube, desulfurization pipeline,in addition also widely used in the following industries:

Q&A

Self-propagating high temperature synthesis (SHS) is used to describe a process in which the initial reagents (usually powders), when ignited, spontaneously transform into products due to the exothermitic heat of reaction.

A well-known example of SHS reaction is the thermite reaction given below:

化学反应式

This reaction generates temperatures above the melting point of alumina and is used in the thermit welding process for joining railway lines.

Several other terminologies - such as combustion synthesis, gasless combustion or self-propagating exothermic reaction - are used to describe the process.

The types of material that can be formed using this process include metal borides, silicides, carbides, nitrides, sulphides, aluminides and oxides.

use in power plants

One-hundred-twenty-nine-million tons of coal ash—a byproduct of the coal burning process—is produced every year. Most power plants transport the coal ash in liquid form to large surface impoundments or in solid form at landfills near the facility through long lengths of steel piping, which can range in length from several thousand feet to miles.

Limestone slurry is also commonly used by coal-fired plants for the effective removal of sulfur dioxide and hydrogen chloride from flue gases. These wet scrubber flue gas desulfurization (FGD) systems utilizes a pumped in limestone slurry through which flue gas containing SO2 is passed in absorber spray towers. The limestone slurry reacts with the flue gas, removing the SO2. The limestone in slurry is then converted into calcium sulfate. This waste material produced by the process is then pumped out from the bottom of the spray towers through steel pipe for further treatment for use in commercially viable by-products such as gypsum board and cement.

To deal with the extremely abrasive and caustic nature of these various slurries, plant maintenance managers are looking to a variety of “abrasion resistant” steel pipe products and accessories to replace standard mild steel pipe in these high wear areas.

Pipe Options

Most abrasion resistant pipe options operate on the premise that when two objects meet, the harder object wins. As such, products are available in a variety of increasing hardness, measured on the Brinell Scale from A-R steel (200 BHN) through iron cast pipe (up to 800 BHN).

Unfortunately, any product that is very hard throughout the wall thickness is also brittle. This brittleness is unacceptable as piping systems are constantly flexing and moving as a result of pressure surges and spikes and due to mechanical and physical contact at the facility.
However, one type of pipe delivers the best of both worlds: an induction hardened pipe with an abrasion resistant inner surface that tapers to a strong, yet ductile outer surface.

At 600 BHN, the inner surface of this induction hardened pipe can withstand most common abrasives and tapers to a 250 BHN outer surface that is ductile enough to accommodate normal handling during shipment, installation and maintenance. With this process, pipe can be created in various diameters up to 40”, in varying lengths and wall thickness.
