Ceramic lined composite wear-resistant pipe - a new type of composite material with international advanced level

Development of ceramic lined composite wear-resistant pipe is a national "863" project, which is developed by University of Science and Technology Beijing and is a new type of composite material with international advanced level. Ceramic lined composite wear-resistant pipe from the inside to the outside, by the ceramic layer, the transition layer and the steel tube. The ceramic layer is made of 2600 degrees above the molten aluminum oxide, under the action of centrifugal force, uniform composite in the steel tube after the solidification of the formation of the layer, the layer is dense, smooth, and the steel tube is firm, appropriate, uniform combination.
Ceramic lined wear-resistant pipe with excellent wear resistance, heat resistance, mechanical and thermal shock resistance, easy welding and installation, especially adapted to the wear and erosion of serious material conveying occasions, such as coal, metallurgy, coal, mining, geological and other industries of the material and general road transport. Compared to common seamless steel tube, the service life of the ceramic lined steel composite pipe has grown exponentially, instead of casting Sheng tube, alloy pipe, organic material liner, is an ideal wear-resistant pipes.
The product is countries "863" high-tech new materials experts committee of the key support and promotion of the project, the State Science and Technology Commission and was included in the "Ninth Five Year Plan" national torch plan, the product also in 1994, respectively, through the Ministry of metallurgical industry and the Ministry of electric power scientific research achievements and product identification. Its characteristics are as follows.
Good abrasion resistance: ceramic lined composite steel pipe inner ceramic corundum, Mohs hardness in more than 90, equivalent to more than hrc90, so for electricity, coal, mines the delivery of any media have a high wear resistance.
The loss of operation risk is small, the ceramic lined composite steel pipe is carried out by the authority of the test, the result is ideal.
Engineering cost low: ceramic lined steel composite pipe because of the light weight, the use of high ordered, thereby reducing the installation cost and transportation cost, ceramic lined composite pipe is the total cost of the project and cast stone tube quite, 30 percent to 20 percent lower than the wear-resistant steel pipe. Good temperature resistance, ceramic lined composite steel pipe can be in the range of fifty degrees below zero, the long-term normal operation, the expansion coefficient of the material is 6~8 * 10/ 6.
Easy installation and construction: ceramic lined with wear-resistant pipe weight, compared with the same diameter of other tubes, can save steel thirty percent to twenty, and has a heat resistance and resistance to mechanical impact, such as a good comprehensive performance, can be used welding, flange and other fast connection mode, construction and installation.

Sleeve Type Expansion Joints

Sleeve Type Expansion Joints are primarily designed to compensate for thermal expansion but it is not the only movement being imposed on the pipeline system. Other types of movements can occur that need to be taken into account when providing a pipework flexibility solution such as building settlement, wind loading, vibration from rotating and reciprocating machinery. Related Ceramic lined pipe Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique. The sleeve type expansion joint is also called tube compensator, pipe expansion joints, which is used for hot fluid pipelines, mainly applied to the laying of straight pipelines. And the working medium can be hot water, steam, oil, etc. The sleeve expansion joint does thermal expansion by sliding its external sleeve. Sleeve compensator Types of Sleeve Type Expansion Joint: Buried sleeve expansion joint: Using advanced sealing structure and sealing materials with the features of easy installation...

Tubes Erosion Shields

Tubes Erosion Shields are used to reduce excess wear of boiler tubes within the extreme conditions prevalent inside a fossil fuel fired boiler, Sunny Steel is able to manufacture and supply erosion shield solutions to protect and reduce wear in all applicable boiler related situations. Boiler Tube Shields are designed to eliminate major maintenance and downtime costs from boiler and condenser tube failure. Advantages Tube Shields are custom made to fit perfectly to straight sections, curved sections and even finned and specialised tubing. Boiler Tubes Erosion Shields, also known as anti-corrosion Shields, anti-wear plate, anti-wear protection Shields, anti-wear cover plate, anti-corrosion cover plate, boiler climbing pipe, anti-wear pressure plate, etc. , which are used in combination with snap rings. Boiler Tubes Erosion Shields are produced using a high-pressure press and professional mold pressing. The production time is short, the welding performance is good, the welding should not...

Cast basalt lined steel pipe

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. 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. 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. Flange connection is one kind of common pipeline installation connections. The parameters of the outside steel pipe will be decided according to the working pressure of ...

Large diameter ceramic lined tile pipe

The Ceramic tile lined pipe spool is 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 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. Ceramic tile lined pipe spool is 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. Advantage Super wear-resistant, high density: we use 95% of chromium corundum, 100 tons dry-pressing. Elbows formed by hot-bending, the outside of ...

Ceramic lined pipe expansion joints

Ceramic lined pipe expansion joints are designed to safely absorb the dimensional changes of pipework systems and ducts caused by heat induced expansion and contraction. They are essential in pipework systems that are used to convey substances of a high temperature, such as steam, heated water or exhaust gases. Expansion joints can also be designed for other applications, such as noise and vibration caused by reciprocating machinery, building settlement and in some extreme environments earthquake movement. Expansion joints are very important components with in a pipework system as they not only solve the problems associated with pipework movement but offer such advantages as reducing stresses and loads to connecting equipment such as pumps and steam turbines.
