A lined pipe is a pipeline with a steel or rigid structure as the skeletal pipe, and a lining layer made of rubber with excellent properties such as wear resistance, corrosion resistance, and temperature resistance. It combines the characteristics of metal and rubber, creating a pipeline equipment that is balanced in its rigidity and flexibility. Through the physical and chemical properties of the rubber, it reduces the impact and corrosion on the external structure of the pipeline medium, resulting in high strength, high wear resistance, high corrosion resistance, and high-temperature resistance. This significantly extends the service life of the pipeline and reduces the cost for the user.
