A lined pipe is a pipeline with a steel or rigid structural framework on the outside, and a lining layer made of wear-resistant, corrosion-resistant, and high-temperature-resistant rubber. This combines the metallic and rubber properties, creating a pipeline equipment that is a perfect blend of rigidity and flexibility. By leveraging the physical and chemical properties of the rubber, it reduces the effects of the transported medium on the external structure, such as impact force and corrosion. This results in the pipeline having high strength, excellent wear resistance, strong corrosion resistance, and high-temperature tolerance, significantly extending the service life of the pipeline and lowering the user's costs.
