Analysis of Standard and Technical Parameters of Viscoelastic Tape

Viscoelastic tape are used widely in the field of pipeline anticorrosion. But many customers are not familiar with the performance of viscoelastic tapes, such as application standard and acceptance standard. Besides, how does the viscoelastic tape protect metal, when the adhesion between viscoelastic tape and metal is low. In this paper, 5 kinds of viscoelastic tape and outer protection tapes are introduce. They are viscoelastic tape of ST and HT, viscopaste, viscocure of HT, PE outer protection tape. These products can be used cooperatively according to different temperatures, the anticorrosion effect is good. And the CSA and GB standard of each performance test are listed. The appropriate application and operating environments for viscoelastic tapes are clear and definite through comparison and explaining technology parameters. Two sucessful project cases are listed.
