Application of bimetal wear-resistant elbow in pulverized coal conveying pipeline

Bimetal wear-resistant elbows are commonly used in mine pipelines. In pipeline systems, bimetal wear-resistant composite elbows are pipe fittings that change the direction of pipelines. According to the angle, there are three most commonly used ones, 45°, 60°, and 90°. In addition, according to engineering needs, other abnormal angle elbows such as 30°40° are also included. The material of bimetal wear-resistant elbow is composed of carbon steel 20# elbow and high-quality high-quality alloy wear-resistant material. There are two ways to connect with the pipe: direct welding and flange connection, and the loop flange connection is the most commonly used.
In the pulverized coal conveying pipeline using the boiler of the thermal power plant, factors such as anti-riot, anti-wear, anti-blocking, anti-leakage, anti-corrosion, anti-rain, anti-freezing and other factors must be considered in the design for the connection at the corner of the pipeline. The main points are anti-wear and anti-corrosion. The wear-resistant elbow of pulverized coal pipeline is particularly serious. It has been the key part of power plant maintenance for a long time. The comprehensive performance of the pipeline system, especially the wear resistance, is directly related to the safety of the entire power plant. Operating costs and economic benefits are issues that must be considered in the engineering and maintenance of new power plants.
