Rare earth alloy wear-resistant pipe

Description

In fact, Rare earth alloy wear-resistant pipe is still widely used in coal washing plants. As we all know, the environment of coal washing plants is very harsh, and there are particles in it that are easy to wear. Rare earth alloy wear-resistant elbow material is good in terms of cost performance and wear resistance. There are certain reasons why coal washing plants recommend it highly. Moreover, Rare earth alloy wear-resistant cast pipe can be cut and welded at will in industrial mines, and it is very convenient to install.

What is rare earth alloy wear-resistant pipe?

• Material: ZG40CrNiMoMnSiRe
• Hardness: HRC≥40
• Impact toughness: ≥14J/cm2
• Tensile strength: ≥700MPa

With wear resistance and heat resistance, the wear resistance is 10 times that of ordinary steel pipes, and the temperature resistance range can reach ≤400 ° C. It can be cut and welded at will, and is very convenient for construction and installation.

Coal washing plant abrasion resistant pipe fittings under the same conditions as compared with the high manganese steel materials, the unit is a high-manganese steel wear about 1/3, life is more than three times as high manganese steel. Bends and branches seamless steel pipe segment with supporting the use, manufacture applicable irregular pipelines, cutting, welding easy maintenance.

Abrasive wear is a serious form of wear among all kinds of wear, and its essence is the result of the cutting or chiseling action of hard abrasive particles on the metal surface. The abrasive particles penetrate the metal surface to produce plastic deformation and wear scars until the metal surface is abraded. The new high strength low alloy rare earth wear resistant steel pipe is developed according to this principle, and the components are various alloying elements such as Cr, Ni, V, Mo, W, and Cu.

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.

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 steels / steeled tube wear-resistant materials can resist wear and prolong the life of the product. Mainly divided into the 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 alloy 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.
