expansion bellow guide gen.

[adelaida]

Пожалуйста, помогите уточнить смысл "guide" из:

Ammonia Plant and Urea Plant,
UREA MELT PRELIMINARY OPERATING MANUAL

Inspection immediately after erection
The following points must be checked:
Vertical position of the stripper.
The vertical position of the stripper is to be checked with a plumb line or a theodolite.
An additional check should be carried out through the tubes.
The maximum allowable deviation from the vertical is 1 mm per meter tube length.
Before this check can be made, the bolts of the ***expansion bellow guide must be loosened.

Затрудняет "guide"

Спасибо.
