Pre-compressed hybrid packing set with skive cut made of expanded graphite, special impregnation and reinforcement to protect against extrusion
Characteristics
Packingset made by combining two expanded Graphite grades and designs. Both are reinforced with a inconel matrix in order to avoid blow out and extrusion. The combination enhances the sealability. The set was tested and approved by Yarmouth Research, Maine in USA.
The tighteness class is CH with a max. leakage rate of <4,5E-3mbar.l/s. The endurance class is CO1 with 2 thermal cycles and 205 mechanical cycles. Number of Packing adjustments (SSA) 1. Test pressure: 20°C @ 51,1bar and 400°C @ 34,7bar. Test fluid Helium. Performance Class ISO FE CH-CO1-SSA1-t400C-ANSI Class 300 - ISO 15848-1.
The Packingset is therefore recommended as a high grade sealing system.
