A lined rubber pipe is a pipeline equipment that combines the metal and rubber properties, featuring a steel or rigid structure as the pipeline frame and a lining layer made of rubber with excellent wear-resistant, corrosion-resistant, and heat-resistant properties. It integrates the strengths of both materials, creating a balance between rigidity and flexibility. The rubber's inherent physical and chemical properties reduce the impact and corrosion forces on the external structure of the pipeline, resulting in high strength, excellent wear resistance, strong corrosion resistance, and high-temperature resistance. This significantly extends the service life of the pipeline and reduces the cost for users.
