7.0 Stopping Operation:
Pull stopper rod out by unscrewing brass cap and
pull rod all the way out.
Attach the appropriate gauges on the appropriate
couplings at the top of the stopper rod.
Each gauge has a specific function. The gold
connection gauge will indicate the pressure inside
the pipeline in front of the MDS Stopper. The
silver connection gauge indicates the inflation
pressure of the inflatable stopper.
internal / inflation pressure
system / pipeline pressure
Verify that the coupling on the bottom of the
stopper rod contains a gasket.
The gasket should be in good visual condition.
The condition of the gasket can be verified when
conducting the vacuum test on the stopper prior to
inserting the stopper into the gas system.
NOTE: Extra stopper rod gaskets should always
be available.
Never use the stopping tool if the gasket is not
inside the coupling.
Take the stopper you selected from the chart in
Section 4.0 and 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.
