Vetter 1 bar cone pipe stopper
Page 14/21
Once work is complete, relieve the pressure via the filling hose or the con-
trol device (pressure relief via the knurled screw on the safety relief valve).
This action must always be performed from
outside
the pipeline or shaft.
9
Once the water has fully drained from the shaft/pipeline, discharge
the compressed air from the stopper.
9
Now remove the shoring and take the stopper out of the shaft/pipeline.
3.3 Shoring
The type of shoring required depends on the struc-
tural conditions in the pipe, on the pipe itself and
on the expected backpressure.
3.4 Shutting off the pipeline
DANGER!
Risk of death for persons in shafts and in pressurised pipe-
lines during a pressure check!
• Personnel: - Instructed person
• Protective equipment: - Safety gloves
- Safety shoes
- Face, head and ear protection
- Protective clothing
Cone pipe stoppers can be used for different pipe diameters
(see label on the cone pipe stopper).
9
Select a cone pipe stopper, filling hose, control device and com-
pressed air source.
9
Make sure that there are no branch pipes, service connections or
similar in the section of pipe to be shut off.
9
Connect the cone pipe stopper to the filling hose and control device
and insert it into the pipe.
9
From a secure position, fill the cone pipe stopper from above to the
maximum permissible operating pressure.
9
If a pipeline is to be shut off with a cone pipe stopper, generally
monitor the operating pressure on the control device (e.g. possible
pressure changes due to temperature fluctuation). See separate op-
erating manual for the control device.
