graphite ring is made of low-sulfur expanded graphite tape by winding and molding, with precise size, fixed density, and without any external fillers or adhesives. Generally, the cross-section is square, but also can be wedge-shaped V-shaped. The latter two are suitable for high-pressure parts, reinforced graphite packing ring, expanded graphite packing ring, lined with stainless steel foil, net, etc., which can improve the pressure capacity. Corrosion-inhibited graphite packing ring application: It has the characteristics of expanded graphite and can withstand violent alternating temperature and pressure. It is an ideal packing for valves and various static seals. In addition to avoiding use when the valve stem is severely damaged, it can be used alone or in combination with high carbon fiber packing end rings to prevent packing extrusion.
