T-Rack
®
Geometric Flexibility
NOTE
The T-Rack
®
3.0 is designed to allow expansion as well as
contraction and is therefore flexible. This is necessary to allow
differences in temperature and pressure. The maximum difference
between the length of a T-Rack
®
3.0
in ‘as-built’ condition to the
length after pressurizing is about
2 mm
per T-piece composite
coupling.
NOTE
The T-Rack
®
can contract further when the T-Rack
®
3.0 is exposed
to pressures below atmospheric (vacuum). The T-Rack
®
3.0 is not
designed for vacuum conditions.
NOTE
The T-Rack
®
3.0 is designed with connection options on both
sides.
If it is required to connect the T-Rack
®
3.0 with pipework on both
sides, this pipework should be able to adjust to the full expansion
and contraction possibility of the T-Rack
®
3.0. In installations
where both the bottom as well as the top feed headers of the T-
Rack
®
3.0 are connected to fixed pipework, a device for adjusting
to expansion and contraction can be omitted as long as the feed
pressure is below 3 bar.
