7.1 Vetter Egg Profile Bags 1 & 1.5 bar
Description
Vetter egg profile sealing bags 1 and 1.5 bar can be used for blocking
egg-shaped pipelines and channel lines during repair and maintenance
work, e.g. channel inspection, maintenance and cleaning.
9 Please observe the specified sizes of egg profile bags: e.g. EDK 60/90
– the first number is the diameter in cm of the upper area of the pro-
file, the second number gives the size of the inside height of the egg
profile in cm (refer to the drawing below).
9 Also please observe the permitted maximum counter-pressure of 5
m water column, resp. 0.5 bar, when using the egg profile sealing
bag.
Vetter egg profile sealing bags 1 bar can be folded in the deflated con-
dition so that they are able to be inserted through a standard shaft ope-
ning of 600 mm.
The egg profile sealing bag EDK 35/52.5 –50/75 1.5 bar can be used for
a number of profile sizes.
Egg profile sealing bags 1 bar are used for the specified size.
9 Connect the 1.5 bar inflation hose (plug-in nipple/coupling) or 1 bar
inflation hose (claw coupling) to the connection coupling of the egg
profile sealing bag 1.5 bar, resp. 1 bar, and also to the 1.5 bar, resp. 1
bar, connection nipple/coupling of the controller.
9 Position the whole length of the sealing bag into the pipeline and
secure it with a suitable device, e.g. with a structure support, in order
to stop it from catapulting outwards.
9 Inflation of the sealing bag can then be made according to descrip-
tion given in chapter 4.
