9. Tube integrity and Lubrication
Tube integrity and lubrication are entirely the responsibility of the opera-
tor.
To be sure that the tube into which the cable is to be inserted is installed appropriately, it is
recommended that its integrity and lubrication be checked.
Check that the tube is:
1.
Not blocked
2.
Not crushed
3.
Continuous (no breaks)
4.
Also check that any couplers are pressure tight
5.
Finally check that the tube is appropriately lubricated
The easiest and most straightforward way to complete these checks is to set the machine up
for a normal cable insertion but fit a seal in place of the cable. The tube can then be pressur-
ized without running the roller drive.
The checks listed at 1
-
4 (inclusive) above may all be carried out at the same time using one
check. The procedure is outlined below. Set up the air box and tube clamp as shown.
CAUTION:
Any object inadvertently left in the tube during the tube installa-
tion may be expelled from the end of the tube with high force and velocity. It is
imperative that no personnel be in the vicinity of the end of the tube or that a
suitable device is fitted to the end of the tube to arrest any expelled object.
When the air box has been set up as shown in the photo, the air box and tube clamp should
be closed as for usual cable installation.
Fit the tube and tube seal in
position as for normal cable
installation.
Fit the appropriate
solid plug as shown
