Three-way coal powder expansion joint

　　The three-way coal powder expansion joint is specially designed for coal powder conveying pipeline systems. It consists of components such as a corrugated pipe, connecting flange, and guiding bracket. Its unique corrugated pipe design allows for flexible expansion and contraction in axial, lateral, and angular directions, effectively compensating for displacements caused by temperature changes, pipeline vibrations, and installation errors during the coal powder conveying process. This expansion joint is made of highly wear-resistant materials, capable of withstanding the abrasive wear of coal powder, while also possessing good sealing performance to prevent coal powder leakage. It is widely used in industrial fields involving coal powder transportation, such as thermal power generation and steel smelting, ensuring stable operation of pipelines, reducing failures caused by displacement issues, and improving production efficiency. It is a key device for ensuring the reliable operation of coal powder conveying systems.
