(jjj)s UNWEL L Gaskets - Spiral Wound Gaskets - KAMMPRO-SPIRAL Spiral Wound Gasket with PTFE Enveloped Inner Ring SUNWELL Code: SUNWELL KAMMPRO-SPIRAL Stype KAMMPRO-SPIRAL gaskets are desinged for highly corrosive applications, such as Hydrofluoric Acid (HF), This style offers the advantage of having double sealing design which occupies all the space from the bore of the pipe to the outer diameter of raised face flanges. The spiral wound can be fabricated to the customers specifications. Typically, we will use either Kammprofile Carbon Steel (Teflon Coated) or Monel Inner ring faced with Graphite or PTFE. This Kammprofile Inner ring is affixed to the “special” spiral wound. The GSI-HF gaskets are designed to prevent corrosion on the flange faces, especially in HF service. CGI Winding -Graphite -Monel. Monel Kammprofile Inner Ring - Graphite Faced CGI Winding -Graphite - Monel. PTFE Coated Carbon Steel Kammprofile Inner Ring - Graphite Faced CGI Winding -Graphite -Monel. PTFE Coated Carbon Steel Kammprofile Inner Ring - EPTFE Faced / PTFE Enveloped CGI Winding -Graphite - Monel. Monel Kammprofile Inner Ring - EPTFE Faced / PTFE Enveloped The winding portion is the main sealing element but once compressed the inner kammprofile creates a seal and stop HF attack on the inner bore of the flange faces. The inner ring is designed to sit on the inner bore of the pipe to stop HF build up in this area.
