Single-type coal powder expansion joint

　　The single coal powder expansion joint is specially designed for coal powder conveying pipeline systems. It mainly consists of a corrugated pipe, connecting end pipes, and sealing components. During the coal powder conveying process, the pipeline is prone to expansion and contraction due to temperature changes and airflow impacts. At this time, the corrugated pipe plays a key role, efficiently compensating for pipeline displacement with its own elastic expansion and contraction, preventing pipeline damage caused by stress concentration. It is made of highly wear-resistant materials, capable of withstanding long-term erosion and wear from coal powder, while the sealing components ensure no leakage of coal powder. This expansion joint has a simple structure and is easy to install, widely used in industries with large coal powder conveying volumes, such as thermal power generation and cement manufacturing, effectively ensuring stable pipeline operation, reducing maintenance costs, and improving production efficiency. It is an indispensable important component of coal powder conveying pipelines.
