Lined pipes are a type of pipeline with a steel or rigid structure as the backbone, lined with wear-resistant, corrosion-resistant, and heat-resistant rubber. This combines the properties of metals and rubbers into a balanced, versatile pipeline device. The rubber's inherent physical and chemical properties reduce the impact and corrosion on the external structure of the pipeline medium, resulting in high strength, excellent wear resistance, superior corrosion resistance, and high-temperature tolerance. This significantly extends the lifespan of the pipeline and reduces the cost for users.
