Pressure is high. Applicable to any pressure level. Use in conjunction with the outer lining tight, using a special process to form a connection between the composite layer solution to ensure the reliability of operation, has good resistance to mechanical shock, thermal shock resistance, easy installation and connection, any cutting, welding.
Wear-resistant alloy steel tubes for the base, lined with super wear-resistant alloy by centrifugal casting, metallurgical combine to form a solid body. LFC elbow vacuum casting process. Resistant alloy tube both excellent wear resistance, high temperature resistance and impact resistance, but also has good toughness, excellent thermal shock resistance to mechanical properties, welding performance, easy installation. Especially suitable for high temperature wear cold shock. Such as electric power, metallurgy, coal, mining, cement and other material handling industry. The product is compared with other wear-resistant pipe, long life, cost of investment economy.
Compared with corrosion-resistant alloy pipe, bimetal composite pipe has higher strength.
Compared with common steel pipe with internal anti-corrosion coating, bimetal composite pipe has better abrasion resistance.
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.
The late eighty`s, American technology of rare eath wear resistant steel was introduced into our country. The relevant experts researched and made many experiments. The rare-earth wear-resistant steel had occupied the main position.Rare-earth wear-resistant steel is based on 40 steel. Cr, Ni, Si, Mo, Mn, Re elements are mixed in 40 steel forming low alloy steel which carbon content is 0.35~ 0.45%.
Rare earth alloy bimetal pipe is in the serious abrasion of the parts, such as elbows, different diameter pipe, water inlet and the overall model casting, and then the mechanical processing method, especially on the outer side of the elbow wear is particularly striking parts of, external diameter of the circle method to carry on the design change, the wear serious parts of locally thickened, but also according to the requirements of the various produce all kinds of irregular switch fittings to meet the design requirements, the straight tube is by centrifugal casting. Two is a rare earth wear-resistant alloy containing Ni, Mo, W, V, Cr, Cu and other alloy elements, which not only has a high hardness, but also has a certain mechanical properties, has good welding performance at room temperature, and has the possibility of cutting and opening the hole, but also has a certain anti corrosion performance.
My company and major universities jointly developed a new type of high-strength wear-resistant alloy of rare earth products, it is crucial to overcome the technical material of cold, heat, cracking, brittleness, deformation, etc., with high strength, good toughness, corrosion resistance, weldability well, the process is using the most advanced centrifugal casting, long life, under the same conditions than the high manganese steel materials, wear the unit around one-third of the high manganese steel, high manganese steel service life is three times above. Bends and branches seamless steel pipe sections with supporting the use, installation and maintenance more convenient.
These Steel-High-chromium alloy Bi-metal pipe elbows is a new type of abrasion proof piping developed by our company. Outer of straight pipe is common steel pepe, cladding realized by forming high chromium lining via centrifugal forming technique.
Outer of bend uses hot-bending bend and lining is cast with high-chromium cast iron. Compared with traditional wear-resistant alloy cast iron, wear-resistant alloy cast steel, general cladding steel pipe and cast stone pipe.
Electricity Industry: Coal power plant coal transmission pipeline, fly ash exhaust system, chemical water circulation system, desulfurizing system and all the corrosive areas in the nuclear electrical power plant.
Rare earth alloy bimetal pipe bend

The outside wall of the clad pipe is steel pipe, and the inner wall adopts anti-abrasion high Cr alloy. Clad pipes not only have the anti-corrosion prosperities of high Cr alloy, but also have relative high mechanic intension and impact-resistance performance of steel. These kinds of clad pipes have solved the contraction between anti-abrasion and weldability. So they can make the best use of the materials` performances to ensure a safe and credible application.
