A rubber-lining pipe is a pipeline with a steel or rigid structure as the skeletal pipe, lined with a rubber layer that excels in wear resistance, corrosion resistance, and temperature resistance. It combines the characteristics of metal and rubber, creating a balanced combination of rigidity and flexibility. The rubber's inherent physical and chemical properties reduce the impact and corrosion effects on the external structure of the transported medium, resulting in high strength, excellent wear resistance, superior corrosion resistance, and high-temperature resistance. This significantly extends the service life of the pipeline and reduces the user's costs.
