Description
The compression, recovery and leakage properties are achieved from. Fig 1.1
• Profile offset
• Precisely machined flats (length of flats) in-between the raised sections.
• Tested and qualified angles on the raised sections of XRG.
• The precisely machined gasket core design.
RECOVERY TESTING XRG
Fig 1.2 details the thickness change of XRG and s Spiral Wound Gasket (SWG). The gasket stress is increased and reduced at three different temperatures.
The compression and recovery is constant at the three temperatures for XRG and remains stable as the stress increases. The XRG has the ability to compress and recover at high loads.
• XRG demonstrates consistent recovery throughout the gasket stress range.
• The resilience of the XRG remains, even at the different temperatures.
• Conversely, the SWG simply compresses to the guide ring and then fails to recovery after compression.
