IMPP(Injection Moulded Polypropylene)coatings is a new technology for offshore pipeline field joints.It is featured by its high temperature resistance,high wear resistance,good corrosion resistance,high degree of application automation and easy control of application quality.IMPP has solved the difficulties of field joint coatings of high temperaturepipeline,which has been widely used on projects in middle east,but not used in China by now.The experience of applying IMPP on a foreign project by our company was introduced in thispaper.The application process of IMPP coatings included surface treatment,FBE(fusion bond epoxy)spraying,CMPP(chemical modified polypropylene)spraying and PP injection processes,and the main equipment used were closed cycle abrasive blasting equipment,induction heating equipment,fluidized bed,powder spraying gun,radiation heating equipment and PP injection equipment.
