Rare earth alloy wear-resistant tube

Date:2019-08-29    View:3307      Tags:Rare earth alloy wear-resistant tube


The rare earth alloy wear- esistant pipe is used for pneumatic, pump slurry, etc. Rare earth alloy wear resistant pipe has the characteristics of fast velocity and high flow rate. The conveying medium temporarily continues to produce impact on the pipe wall, wear, corrosion and so on, which causes the pipe to become tired and gradually wear out.

Rare earth alloy wear - resistant tube is badly worn parts, such as pipe, elbow, reducer, and water intake place such as the model of integral casting, then mechanical processing method, especially the outer wear parts, especially in the elbow to the outer diameter change circle method is adopted to carry on the design, local thickening severe wear parts, but also according to various requirements, produce all kinds of irregular switch pipe fittings to meet the design requirements, straight tube is using centrifugal casting.Rare-earth wear-resistant alloy containing Cr, Ni, V, Mo, W, a variety of alloy element such as Cu, it not only has high hardness, but also has certain mechanical properties, at room temperature with good welding performance, and can be cut and the possibility of opening, also has certain corrosion resistance.
