√ Applied in high pressure medium, like, light hydrocarbon, aromatic hydrocarbon, ethylene, propylene ,etc.
√ Prevent medium leaking into the atmospheric, usually micro leakage inside should be discharged into the flare system;
√ High pressure seal in process side, the unique design of the primary ring is beneficial to reduce the deformation of seal faces and increase the heat dissipation area;
√ Short axial dimension and compact designs
Features:
● Double seal with tandem arrangement
● High pressure seals in process side
● multiple springs, rotary
● Torque transmitted by lugs
● Dent drive
Recommended applications:
√ Refining & petrochemical
√ Coal chemical
√ Chemical
√ General industry
Piping plans:
● Process side:API682 PLAN 11, 21, 32,
● Between seals:API682 PLAN 52, 55
