Aiming at short service life of existing composite piping used in the interaction of corrosion and wear, three element composite piping with anti corrosion and wear resistance was fabricated. The newly developed composite piping that composed of three layers materials such as metal, ceramic and polymer was made by reactive processing technology and reactive impregnation technology. The corrosion resistances of product in different corrosive medium and temperature were characterized and evaluated as well. Successful engineering cases show that the three element composite piping has excellent properties of anti corrosion,wear resistance, and scaling proof, especially possesses long service life and high performance cost ratio in the application of complex operation situations such as composite corrosion, erosion corrosion,high temperature and negative pressure.
