SecureFlex Single Arch DuPont Kevlar® Reinforced Non-Metallic Expansion Joint
The SecureFlex Van Stone interlocking flanges are compatible to mate with Lap-Joint Stub ends, Raised Face or Flat Full Face type flanges. For other mating flange surfaces (wafer type check or butterfly valves), a full face hard spacer may be required. Consult UIP International, Inc. Engineering. The standard floating flanges are 150# drilled epoxy-coated carbon steel. Galvanized, stainless steel and other alloy type materials are also available. DIN-PN-JIS and other non-standard drill patterns customizable to your needs.
Kevlar® wrapped around a solid steel ring in the base of the rubber flange portion eliminates the tire cord from “pulling out” of the flange and provides superior sealing force when compressed against the mating flange during installation. The ring also prevents the distortion of the sealing surface if the installation tolerance is exceeded providing an “extra” margin of safety. Polyester tire cord may be substituted, with customer approval, for sizes 14” and above if design temperature does not exceed 250°F.
