Refurbishment & Revamp
All existing expansion joints are candidates for our services and
existing parts inventory may be used wherever technically possible
in delivering the required solution. Refurbishment & revamp solutions
work with the expansion joint still in the process line wherever
possible, this has signifi cant advantages for the plant owner:
- Reduced risk – minimum intervention, large heavy circumferential
welds eliminated
- Reduced cost – structures can be left in place, heavy lifting
avoided, few key parts only required for the rebuild.
During critical turnarounds on major units SFP’s fi eld service capability
will make a very signifi cant contribution to the project. The
approach taken on ever project is tailored to the client’s precise
needs and plant conditions.
In situ refurbishment of a joint - What we do
- Remove covers and insulation
- Constrain pipe / duct, block hangers
- Remove hinges or other hardware
- Detach bellows element / remove attach ment weld
- Separate joint using existing freedom in the pipe system
- Remove old bellows
- Check and rework as necessary liner
- Replace any internal insulation and seals
- Insert new bellows – upgrade materials, 2-ply testable,
all options can be used
- Re-weld attachments
- Reassemble hardware
- Replace insulation, replace covers
Saving
Cutting out of old joint
Saves water jet costs, time and major disturbance to the piping. Very
often getting the old joints out is very hard work, heavy cranes are
needed to support the piping and get the parts in and out.
All existing hardware
The hardware is very unlikely to be damaged, as it is a low
temperature. It is expensive to reproduce.
Heavy welding to ageing, crack-prone pipe
When welding in a new joint a circumferential weld has to be made
very close to the heat-affected-zone of the original weld. The pipe
material once it has been in service is very prone to cracking which
makes this re-weld risky.
Replacement of refractory in-side the pipe where cutting has taken
place
It is impossible to remove the old joint without signifi cant damage
to the lining of the pipe. By avoiding the cut the refractory work is
avoided saving signifi cant time and cost.
Costs of all parts and shipments not absolutely needed
Only the key bellows and seal elements need be bought and
shipped
- Turnaround programme is reduced
- Risks inherent in joint replacement are reduced – welding /
cracking / fitting
- Time expended by the main mechanical contractors reduced
and specialists work on the critical components.
- Additional parallel working is possible as work is removed
form the mechanical contractors scope.
- Hardware and shipping costs are dramatically reduced.
