ISOGUARD™ Sealing/Isolation Gaskets
ISOGUARD™ isolation kits feature GRE gaskets with quality pressure energised seals. The inclined plane grroce and one piece seal element create a dynamic and reliable seal with guaranteed corrosion protection. A range of materials offer a service range from -150°c to plus 200°c.
DEFENDER™ Sealing/Isolation Gaskets
DEFENDER™ isolation kits contain a steel core with GRE bonded to both sides for ultimate strength and integrity. Spring loaded PFTE seals are locked into machined grooves ensuring that the seals are anchoired into the steel core. DEFENDER is proven in the most hostile service environments inclusing H2s “sour” service. DEFENDER can be specified for pressure ratings up to API 6A 15000.
DEFENDER FS™ Sealing/Isolation Gaskets (Fire Safe)
DEFENDER™ fire safe isolation kits are the ultimate in corrosion protection, seal security and fire protection all in one. The Kammprofile core and Matrix PTFE primary seal ensures seal integrity at the highest pressures while the special PTFE coating and GRE complete the flange isolation. In the event of a fire special washers and a secondary seal prevent the flange from failing. Tested and accredited to API 6FB “fire safe”.
Sleeve and Washer Sets
Shuk Engineering sleeve and washers sets, when combined with our sealing/isolation gaskets, complete a Flange Isolation Kit. For a successful flange isolation kit, it’s critical to use the appropriate material for your application. Compressive strength, flexural strength, and cut through resistance are key material physical properties that should not be over looked.
