Abstract
Recently slurry pipeline system has been successfully used for the transportation of coal, iron ore, iron sand, dredged sand and many kinds of tailings.
The slurry transportation system has many advantages such as efficient use of energy, reliability, and protection of the environment. However, it has also been recognized that the wearing of pipe caused serious problems.
Polyurethane is well known for its excellent resistance to abrasion, though the water vapor permeation rate is significant.
The abrasion and anticorrosive properties of polyurethane lined steel pipe were investigated and discussed.
