What 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.

Surface Quality requirements: the internal and external surface of the pipeline should be smooth and smooth, no burrs, burrs, sticky sand, more meat or lack of meat, no cracks, loose, stomata or bubbles.

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.

High strength and low alloy rare earth heat-resisting and wear-resisting steel pipe parts are suitable for coal conveying, powder feeding, ash discharging pipeline and coal preparation plant transportation pipeline in thermal power plant boiler system.
