Yanggu - Ultra High Molecular Weight Polyethylene Lined Steel Pipe
The Dragon UHMWPE Lined Steel Pipe is a specialized pipeline developed by Dragon UHMWPE. It consists of a steel pipe with an Ultra-High Molecular Weight Polyethylene (UHMWPE) liner, combining the strength of steel with the durability of UHMWPE.
Construction: The UHMWPE liner is inserted into the steel pipe using shrinkage technology, ensuring a tight fit. The steel pipe serves as the outer layer to withstand pressure, while the UHMWPE liner acts as the inner layer, providing exceptional resistance to wear and extending the pipe`s service life.
Sealing Design: The sealing face of the UHMWPE lined steel pipe is a UHMWPE stub. This stub is formed by flanging and heating the UHMWPE liner itself, ensuring a seamless and reliable sealing interface.
Connection Method: The pipes are connected via the UHMWPE stub sealing face and steel flanges. These flanges are welded to the ends of the steel pipe, creating a secure and robust connection.
This innovative design ensures high performance in demanding applications, making Dragon UHMWPE Lined Steel Pipes an excellent choice for industries requiring durability and reliability in pipeline systems.

With the above properties of UHMWPE liner, the mainly application of Dragon UHMWPE lined steel pipe is for mine tailings transport as tailings pipeline. In the mining industry, transporting tailings—the waste materials left after the extraction of valuable minerals—presents a significant challenge. The solution to this challenge lies in choosing the right pipeline material, as tailings can be abrasive, corrosive, and prone to causing erosion and wear on traditional mining pipeline systems. Ultra-High-Molecular-Weight Polyethylene (UHMWPE) lined steel pipe has emerged as a reliable, cost-effective solution to address these issues, offering a long-lasting and durable option for mine tailings pipelines.
When uhmwpe pipes used as mining pipeline, there are pressure derating when temperature gets higher, besides that, UHMWPE pipe has pressure holding ability limitations for transport pipeline. UHMWPE lined steel pipes are just invented to fulfill the above limitations of UHMWPE pipes.
