7.0 Stopping Operation:
Install the appropriate gauges on the appropriate
couplings at the top of the gauge rod.
Gold: The gold connection gauge will indicate the
pressure inside the pipeline in front of the MDS
Stopper.
Silver: The silver connection gauge indicates the
inflation pressure of the inflatable stopper.
system / pipeline pressure
internal / inflation pressure
Verify that the coupling on the bottom of the
gauge rod contains a seal. The seal should be in
good condition.
NOTE: Extra gauge rod seals should always be
available.
Never use the stopping tool if the seal is not inside
the coupling.
Visually inspect that the stopper is in good
condition without weak spots or concern for
integrity.
(If the condition of the stopper is uncertain, refer
to Appendix A for additional stopper testing and
verification.)
Pre-bend the hose of the MDS Stopper as this will
facilitate the positioning of the stopper into the
pipeline through the chute.
NEVER pre-bend the MDS Stopper on the
frame!!! This can damage the frame and it will not
help as the internal frame is rigid.
