Abstract

Viscoelastic anticorrosive tape is extensively used for repairing anticorrosive layers on compressor outlet pipelines in the oil and gas industry. However, there is no relevant research on the coupling effect of temperature and vibration on the performance of viscoelastic anticorrosive tape. In this paper, acceleration tests of temperature and vibration coupling conditions were conducted to investigate the performance of viscoelastic anticorrosive tape. After temperature and vibration treatment, the specimens showed wide variance in thickness, and the adhesion and chemical soaking resistance of the tape was reduced. However, the viscoelastic anticorrosive tape still showed high adhesion. According to theoretical calculations, the tested viscoelastic body can repair pipes with a maximum diameter of 903 mm. Therefore, this viscoelastic anticorrosive tape is suitable for the compressor outlets of buried pipelines with diameters smaller than 903 mm. The research in this paper provides a method and basis for the selection of repairing materials for the anticorrosion coatings of compressor outlet pipelines.
