A lined rubber pipe is a pipeline equipment that combines the metallic and rubber properties, featuring a steel or rigid structure as the outer casing and a lining made of rubber with excellent wear-resistant, anti-corrosion, and heat-resistant properties. This design integrates the benefits of both materials, creating a balanced combination of rigidity and flexibility. The rubber's inherent physical and chemical properties reduce the impact and corrosion on the external structure of the pipeline, resulting in high strength, wear resistance, corrosion resistance, and heat resistance. This significantly extends the service life of the pipeline and lowers the cost for users.
