SPIRALIT® AF 632 Packing
The SPIRALIT AF 632 is made from layers of flexible graphite tape plied into compact strands; each individual filament is reinforced with an Inconel wire jacket. This yarn is then treated in a special process and then braided to form a dense yet malleable packing, which is subsequently treated with lubricating agents to reduce stem friction and a corrosion inhibitor to prevent pi?ng. (Inconel is a registered trademark of International Co.).
SPIRALIT AF 632 is a special valve packing which assures extremely low emission, especially designed for high pressure and high temperature service. It is self-lubricating, non hardening, dimensionally stable and easy to install. The Inconel wire mesh covering makes this packing highly resistant to extrusion, the advanced construction assures supreme leakage control and highest integrity in service.
Applicaon: Typical applications for packing style AF 632 include all the valves where LOW EMISSION is a must. This packing is suitable for VOC and VHAP emission regulations and exceeds TA-LuF requirements. Further Properties: high mechanical and thermal stability; chemically inert within pH range 0-14; quick and easy to install; low friction, special lubricating system; corrosion inhibitor.
User: Designed for use with most chemicals and gases, SPIRALIT AF 632 can also be used with steam.
Not suitable for highly oxidizing agents at high temperature.
