A lined pipe is a pipeline with a steel or rigid structure as the backbone, lined with a rubber material that excels in wear resistance, corrosion resistance, and temperature tolerance. This combination of metal and rubber properties creates a balanced, flexible pipeline equipment. 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, superior corrosion resistance, and high-temperature resistance. This significantly extends the service life of the pipeline and reduces the cost for users.
