SPIRALIT® AF 222 Packing
SPIRALIT AF 222 is diagonally braided from pure expanded flexible graphite, reinforced at the corners with a high quality pure carbon yarn.
SPIRALIT AF 222 is the newest generation of graphite packings, specifically designed for very demanding applications. Because of the special construction style AF 222 can be used in areas where normal expanded graphite packings fail. The pure carbon fibres reinforcing the corners and body of this packing, make style 2202 at least three times more resistant to extrusion and also extremely pressure resistant.
Style AF 222 lacks the stiffness of conventional carbon or graphite packings. Because of the high proportion of expanded flexible graphite SPIRALIT AF 222 conforms readily to stuffing box configurations, installs easily and requires li:le gland adjustments. Excellent extrusion resistance. Fire-Safe certificate.
Application: This unique and extremely versatle packing can be used in all demanding applications, both static and dynamic. Style AF 222 does not suffer from limitations that prevent general service use in both pumps and valves. It is extremely well suited for high temperature - high pressure installations occuring in power stations, petrochemical plants, steel mills etc..
User: Although designed with an eye on high temperature steam applications, style AF 222 can be used with all chemicals but the most aggressive acids. Very good all-purpose packing which can lower stock volumes considerably.
Not suitable for strong oxidizing agents.
Test & Approvals: Fire Safe.
