A lined rubber pipe is a pipeline equipment that combines the metallic and rubber characteristics, featuring a steel or rigid structure as the pipeline frame and a lining layer made of rubber with excellent properties such as wear resistance, corrosion resistance, and temperature resistance. This integration results in a balance of rigidity and flexibility. The rubber's inherent physical and chemical properties reduce the impact and corrosion effects on the external structure of the pipeline, thus enhancing the pipeline's strength, wear resistance, corrosion resistance, and high-temperature resistance. This significantly extends the service life of the pipeline and lowers the cost for users.
