 Product contained
 Temperature / pressure
 Strategic (risk assessment)
 Physical size/access

Planning
Analysis – Overview
 When a bolted gasketed flange joint is
assembled the gasket seal is subjected to a
compressive force – “W”
 When a system is pressurized the initial
compressive force is relieved by ‘H’
 To maintain seal integrity there must be a
residual compressive force on the gasket when
the system is in service


Maintenance involves opening/closing bolted gasketed joints. Appreciation of the
‘system’ is necessary.

The system fails, not the gasket when there is a leak.

PSI Management
Only when all the components of the bolted gasketed
flanged joint are working together will an effective
long term seal be achieved:
 Selection of correct components for the application
 Careful inspection, preparation, installation and assembly
 Correct bolt tightening

Past Performance
WMC Phosphate Hill
 Major Shut Down – 2003
 Furmanite assisted UKG & WMC with development of shutdown work packs
from Jan – July 2003
 Furmanite - Control of 970 Plant Flanges, including 150 critical on Ammonia
Plant
 20 personnel, including Project Manager, Engineer, Safety Representative all
with the ability to be hands on
 Over 5,500 shutdown man-hours
 Zero Injuries throughout works.
 Zero Leaks at Start-Up.
 Plant Shut Down finished on schedule

Plant Benefits
Safety & Efficiency
 Right first time
 Re-work significantly reduced
 Reduced shutdown duration
 Down time reduced
All above = Plant owner’s confidence increased
All above = Improved Safety performance

Plant Benefits
Efficiency Example
 Critical flanges – Syngas line
 Flange failure – 7 days downtime* at $30,000/hr = $5million
 7 days = 3 days cool down + 1 day rectification + 3 days start
up
 JIMS – 100% success on syngas flanges to date.

Cost of leaks & un-planned re-work is far
greater than cost of avoiding it.
