hen designing pipe supports for
cryogenic services, it is important
to consider pipe load resistance,
which can be divided into vertical loads
(downwards/upwards), axial loads, side loads,
and torsion loads. It is also important to provide:
Adequate insulation to prevent heat gain and
condensation.
Support and movement of the pipe where
required (resting supports, slides and guides).
Anchoring of the pipe where required (stops and
fixed anchors).
Anchoring for the insulation where required,
which depends upon the insulation system
and/or the insulation materials chosen.

challenges faced when
designing pre-insulated
pipe supports for
cryogenic applications.
