W.hat is the material of the rare earth wear-resistant alloy pipe

The wear and tear of rare earth alloy is a phenomenon of material loss caused by relative motion between objects. Rare earth wear-resistant alloy steel tube wear-resistant materials can resist wear and prolong the life of the product. Mainly divided into single metal pipe and composite pipe. According to the shape can be divided into straight pipe, elbow, tee, four-pass, reducer, Fangyuan section and other special-shaped tubes.

表面质量要求：管道的内部和外表面应光滑，光滑，没有毛刺，毛刺，粘性砂，更多的肉类或缺乏肉，没有裂缝，松散，气孔或气泡。

Rare earth wear-resistant pipe, is in the area of serious wear, such as elbow, reducer, suction nozzle, such as the use of the model as a whole casting, especially in the outside of the elbow wear particularly significant parts, the external diameter of the method to change the center of the design, so that the wear serious parts of the local thickening, but also according to various requirements, Make a variety of irregular shaped pipe fittings to meet the design requirements, straight pipe is centrifugal casting. Second, the rare earth wear-resistant alloy containing CR, Ni, Mo, W, V, Cu and many other alloying elements, it not only has a high hardness, but also has a certain mechanical properties, at room temperature with good welding performance, and has the possibility of cutting and on-site openings, but also has a certain corrosion resistance. In the actual use of the process, whether it is in the steel slag pipe, or in the coal preparation plant, such as the use of washing pipes have achieved very good results, in the same conditions compared with high manganese steel, the unit wear is about 1/5 of the higher manganese steel, the service life is high manganese steel 4-5 times, elbow and branch pipe can be used with seamless pipe fittings, installation, maintenance more convenient.
