sealant into the closed sealant injection port. Once pressure starts to build on the pump, open the
sealant injection port to allow sealant to flow into the fitting. (See Figure 5)
5.
Continue injecting sealant until the barrel is empty or the PLIDCO Flange+Repair Ring is full.
Close the sealant injection port. Release any hydraulic pressure on the sealant pump. Disconnect
the sealant barrel from the sealant injection port.
6.
If the barrel is empty, follow the procedures in the PLIDCO Hydraulic Sealant Pump for reloading
sealant. For any other sealant injection pumps, follow their manufacturer's loading procedure.
7.
Continue to inject sealant through the bottom sealant injection port by repeating steps 4 thru 6.
When there are multiple sealant injection ports on a PLIDCO Flange+Repair Ring, close or plug
the port/vent when sealant starts to come out.
8.
Continue to inject until sealant comes out of the top sealant injection port. After sealant comes out
of the top injection port close the sealant injection port.
9.
Slowly and cautiously pump more sealant until the sealant pressure is equal to the line pressure
without any loss in pressure. Wait a couple minutes for sealant pressure to stabilize and hold
without any pressure drop.
10. Repeat step 8 on all sealant injection ports.
11. Remove sealant pump and install pipe plugs into the ends of the sealant injection ports.
Sealant injection on an Active Leak
1.
Select the proper type of sealant from the choices on page 5 for your application.
2.
During installation of the PLIDCO Flange+Repair Ring make sure to have one sealant injection
port as close to the top and as close to the leak as possible but not directly over the leak. This will
show when the annulus of the PLIDCO Flange+Repair Ring is completely filled or that sealant has
reached the top of the fitting. (See Figure 5)
3.
Open all the sealant injection ports slightly. Place pipe plugs into connections without sealant
injection ports. Close the bottom sealant injection port that is being injected into first.
EXCEPTION: If injecting into a PLIDCO Flange+Repair Ring containing high temperatures or
harmful contents that could cause harm to personnel, it is suggested to close all sealant injection
ports except the one closest to the leak and is farthest from the personnel injecting the sealant.
Figure 4 shows the correct orientation for closed and open sealant injection port.
4.
Connect a sealant barrel to the closed sealant injection port on the bottom or farthest injection port
away from the active leak. If clearances are an issue, use the flexible hose adapter. Start to inject
sealant into the closed sealant injection port. Once pressure starts to build on the pump, open the
sealant injection port to inject sealant. (See Figure 5)
5.
Continue injecting sealant until the barrel is empty or the PLIDCO Flange+Repair Ring is full.
Close the sealant injection port. Release any hydraulic pressure on the sealant pump. Disconnect
the sealant barrel from the sealant injection port.
6.
If the barrel is empty, follow the procedures in the PLIDCO Hydraulic Sealant Pump for reloading
sealant. For any other sealant injection pumps, follow their manufacturer's loading procedure.
7.
Continue to inject sealant through the bottom sealant injection port by repeating steps 4 thru 6.
Inject sealant until sealant comes out of the top sealant injection port. After sealant comes out of
the top injection port close the sealant injection port.
8.
Slowly and cautiously pump more sealant until the sealant pressure is equal to the line pressure
without any loss in pressure. Wait a couple minutes for sealant pressure to stabilize and hold
without any pressure drop.
