Spiral wound gasket graphite tape/Graphite Foil
The graphite strip of spiral wound gasket is cut into strips by special tools of high-precision CNC lathe. Compared with the traditional graphite strip, the precision is higher, the damage to the graphite strip is smaller, and the cutting part is smooth without burr, so it is used to produce the graphite spiral wound gasket filling material.
Common specification and size of graphite tape for winding pad:
Thickness: 0.5 ~ 1.0mm
Width: 5.6-6.0mm, 3.9-4.5mm for 4.5mm and 3.2mm respectively,
