A lined pipe is a pipeline with a steel or rigid structural frame externally, utilizing a lining made of high-performance rubber with features such as wear resistance, corrosion resistance, and temperature resistance. It combines the properties of metal and rubber to create a balanced combination of rigidity and flexibility. The rubber's inherent physical and chemical properties reduce the impact and corrosion forces exerted on the external structure by the transported medium, resulting in a pipeline with high strength, wear resistance, corrosion resistance, and high-temperature resistance. This significantly extends the lifespan of the pipeline and reduces the cost for users.
