A rubber-lined pipe is a pipeline equipment that combines the strength of steel or a rigid structure with the wear-resistant, corrosion-resistant, and high-temperature-resistant properties of rubber as the lining. This integration of metal and rubber characteristics creates a balance of rigidity and flexibility. By leveraging the physical and chemical properties of rubber, the impact force and corrosion on the external structure of the pipeline medium are reduced, resulting in a pipeline with high strength, wear resistance, corrosion resistance, and high-temperature resistance. This significantly extends the service life of the pipeline and lowers the user's costs.
