Alloy pipe

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%. Experienced long-term production making and many failures, we summed up a reasonable science and new experience.A certain amount of rare earth element is added into steel can improve the quality of alloy steel and can fining grains also can form a protective film on surface. A certain amount of Mo is added, the alloy under certain temperature and certain antioxidant effect, increase the service life.A certain amount of boron carbide is added, hardness can be controlled in the range HRC45 ~ 65. At the same time solve the contradictions between the hardness and weldability of wear resistant ste...

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. In the actual use of the process, whether it is in the steel slag water pipe or in coal...

1.Wear-resistant white cast iron composite tee: working temperature 600 ℃ or less; 2.Metal thermal expansion coefficient of Wear-resisting layer : (11.65~13.75)×106 (mm/mm·℃),and this is very close to outer metal thermal expansion coefficient. The closer of the thermal expansion coefficient means the closer speed of heat expansion and thermal contraction. performance characteristics of Bimetal composite wear-resistant pipe: 1.Favorable combination property 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. 2. High–wearing feature The inner wall of the anti-abrasion clad pipe is...
