Abstract The vibration of the pipeline act on the gasket sealing surface in the form of fretting wear, reducing the sealing performance. In this paper, an experimental study was described on the fretting wear and frictional mechanism of interface between spiral wound gasket (SWG) and flange. The results showed that the gasket winding structure affects the variation of the friction coefficient fluctuation. Moreover, only the fretting behavior of mixed friction regime (MFR) and slip regime (SR) can be expressed stably. Additionally, fretting wear is dominated by abrasive and adhesive wear, and plastic deformation occurs under high load. The intense wear behavior mainly presented in the circumferential direction of small displacement and the radial friction process of large displacement.
