Abstract: A kind of new heat -shrinkable and pressure-sensitive tape and its production and application were introduced in this paper. This tape as joint coating was featured by its excellent performance of water resistance, anti-corrosion and long term cathodic disbonding tolerance and adhesion to steel, PE and primer. Just applying it on the joint of pipes by proper heating, the tape could come into being joint coating with strong adhesion and tight sealing, which could be used in in-service or newly pipeline joints.

Key words: pipeline, anti-corrosion, joint coating, pressure -sensitive tape
