Installation of the V-Sup
Step B.1.
Preparation of construction location:
−
Make sure the construction area is visibly marked and the transport and emergency routes are clearly indicated.
−
Make sure the surface on which the V-Sup will be installed is
levelled
, the maximum slopes should be accepted.
Check the right-of-way (pipeline route) for any slopes.
−
Make sure the surface on which the V-Sup will be installed is
flat
, unevenness in the terrain of maximum 50 mm
are acceptable. Unevenness larger than 50 mm should be levelled out properly.
−
Make sure the surface on which the V-Sup will be installed is
free of ice, snow, oil, mud, algae
, or any other
substances that have a negative influence on the friction.
−
Make sure the surface on which the V-Sup will be installed is free of obstacles (such as wood, stones, gravel
or any other obstacles).
−
To ensure a safety envelop large enough, the use of the V-sup is recommended within a temperature window
of -30
°
C up to +45
°
C. (-22°F to 113°F)
Step B.2.
Installation of Stackable Beams
−
Each V-Sup Stack will be assembled from stackable beams, placed on top of each other. For every pipe, at
least two V-Sup stacks are necessary.
−
Make sure all beams are
free of ice, snow, oil, mud, algae, or
any other substances that have a negative
influence on the friction.
−
Make sure the V-Sup segments are not damaged, deformed or worn down.
−
Make sure the recesses in the beams lock precisely into each other.
−
The alignment of the V-Sup stacks is of vital importance for the safe functioning of the system. The V-sup stacks
needed for one pipe should be aligned parallel.
−
To give the best support for the pipes, the V-Sup stacks have to be placed at a set distance according to the
pipe length and the amount of V-sup stacks needed. The distance is prescribed as a percentage of the pipe
length. Figure 7 will show the prescribed distances with 2, 3 and 4 supports.
