Lining pipes are a type of pipeline equipment with a steel or rigid structure as the skeletal pipe, and a lining layer made of rubber with excellent wear-resistant, anti-corrosion, and heat-resistant properties. This combines the metallic and rubber characteristics, creating a robust yet flexible pipeline. By leveraging the physical and chemical properties of the rubber, the impact force and corrosion on the external structure of the pipeline are reduced, resulting in high strength, wear resistance, corrosion resistance, and high-temperature resistance. This significantly extends the service life of the pipeline and reduces the cost for users.
