Owing to an increase in demand, all pipe and test sealing
bags will be tted with brass couplings as a standard from
01.01.2012 onwards.
If you still wish to have the safety couplings (blue at
1.5 bar, black at 2.5 bar), we kindly ask you to state
this explicitly when placing an order.

1.2 Correct handling and usage
Page 4/33
Vetter pipe and test sealing bags must, depending on the purpose of the task, only be inated with compressed air to the corresponding pressure level using original ination ttings.
Ination with ination ttings from another manufacturer is classied as contrary to the regulations for correct use.
They are exclusively used for blocking the intended pipes, for leak
sealing testing of pipelines and for construction of a bypass.
Any other application or use going beyond this is classied as
contrary to the regulations for correct use.
An application contrary to the regulations for correct use of Vetter
pipe and test sealing bags includes:
9 Incorrect use, operation or maintenance of pipe and test
sealing bags.
9 Use of the Vetter pipe and test sealing bags with defective
safety devices or incorrectly tted or non-functional ination
ttings.
9 Non-observance of the instructions given in the operating
manual concerning storage, operation and maintenance of
pipe and test sealing bags.
9 Insucient monitoring of accessory parts subject to wear.
9 Incorrectly carried out maintenance work.
Correct use according to regulations also includes
9 The observance of all instructions given in this operating ma-
nual.
9 The observance of the set periods for maintenance and care
specied in the chapter „Maintenance and Care“.
2. Safety instructions
The knowledge and observance of this operating manual are the
preconditions for the use of Vetter pipe and test sealing bags
2.1 General information
The observance of all pertinent work protection regulations and
safety regulations, accident prevention regulations (e.g. safety regulations from the technical authorities – TBG) as well as the recognized technical laws are to be carried out.
The pipeline is to be inspected for damage before using pipe and
test sealing bags. The area in the pipe for the pipe and test sealing
bag must be free of deposits, dirt and foreign bodies, such as fragments, sharp-edged objects etc.
Necessary personal protection devices must be made available:
protection clothing, cloves, helmets, facial and/or eye protection
etc.
Pipe and test sealing bags must be positioned full length in the
pipeline and with the sealing area on the inside wall of the pipe.
All pipe and test sealing bags (round and egg-shaped) must be
non-positively and positively positioned and tted.

2.2 Information about the dangers
Changes and modications to the sealing bags, ination ttings
and ination hoses are not permitted. Operation of Vetter pipe
bags, test bags and bypass bags are only permitted with original
Vetter ination ttings and ination hoses. Parts made by another
manufacturer can inuence safety.
Pipe and test sealing bags are made of a strong expanding material. If this material is expanded beyond its permitted maximum
range then this can cause bursting. No person is allowed to remain within the working area during the pressure test. With a
water pressure test, the pipeline being tested must not have any
direct connection to a high-pressure line (e.g. hydrant).
After positioning the pipe and/or the test sealing bag it is to be
ensured that nobody remain in the channel or in front of the pipe
during ination, as well as during the test procedure and emptying sequence. Before removing the set-up make certain that the
pipeline is not under any pressure and is completely empty.
2.3 Warnings
The pipe and test sealing bags as well as the accessories must be
checked for perfect condition before and after each operation.
Outside the pipeline, Vetter pipe and test sealing bags, 0.5 bar and
1 bar, must only be lled to maximum 0.2 bar for the visual test.
1.5 bar and 2.5 bar bags must only be lled to a maximum of 0.5
bar.
All controllers are tted with a safety valve that has a permitted
maximum operating pressure corresponding to the pipe and test
sealing bag. If the maximum operating pressure of 0.5, 1.5, 2.5 or
6 bar is exceeded then the safety valve will activate. The tolerance
for opening and closing of the safety valve is only permitted to be
a maximum of + 10 %. The set pressure must not be changed. If
the sealing on the top part of the valve is removed then its operation is no longer guaranteed and the safety valve must be exchanged. The permitted inlet pressure on the controller (marking
on the inlet coupling) must not be exceeded.

4. Operation of Pipe and Test Sealing Bags
In this chapter you will nd out how the Vetter pipe and test
sealing bags are applied.
When using the pipe and test sealing bags, observe the
safety instructions given in chapter 2 as well as the pertinent regulations for work protection and safety protection, accident prevention regulations (e.g. the safety
regulations of the technical authorities -TGB) and the generally recognized laws of technology.
4.1 Preparations for operation
with blocking valve
Foot pump 2.5 bar with safety valve
9 Ensure that only authorized sta are in the working area and
danger area.
9 Select a suitable pipe and/or test sealing bag which corres-
ponds to the requirements.
9 Check the bag and the accessories to be used for complete-
ness and damage.
9 Damaged bags and damaged accessory parts must not be
used!
9 The bag diameter must be smaller than the inside diameter of
the pipeline.
9 Ination hose and controller must already be connected to
the sealing bag.
9 Mark the working area.
9 Position the bag (full length) into the pipe.
9 The sealing bag in the pipe is to be supported.
9 Draw the sealing bag to the support structure and inate so
that it can still be moved in the pipeline.
9 The support structure should be made so that the sealing bag
can be supported over a large area.
Page 9/33
Vetter Pipe and Test Sealing Bags
9 Leave the shaft and/or pipeline.
9 Make certain that no sta remain in the area of danger.
9 Inate the sealing bag to the permitted maximum operating
There is a danger of the bag catapulting outwards. The pressure
or water column must be completely reduced within the pipeline
before the support structure is removed. Otherwise the sealing
bag could catapult outwards.
After completion of the work, pressure reduction is to be carried
out via the ination hose (ventilation nipple) or the controller
(pressure reduction via the knurled screw of the safety valve).
Generally this must be made outside the pipeline or shaft.
9 If the water has completely owed out of the shaft / pipeline
pressure from a safe position.
then release the compressed air out of the bag.
9 Now remove the support structure and take the bag out of
the shaft/ pipeline.
4.2 Support structure
The type of support structure depends on the structural factors in
the pipe, the pipe itself and the counter-pressure to be expected.
The following support possibilities are only drawing diagrams and
are given as examples.
