Insulation of piping
Pipe hangers in direct contact with the piping
ProRox ® Rocktight requires a dry, clean (ventilated)
work environment. For outdoor applications, tents
should be erected if necessary, to protect the
unhardened ProRox
® Rocktight wrap (mat) from UV
light.
Note
High temperatures: ProRox ® Rocktight can
be used in temperatures of up to 190 °F
(90 °C).
Chemical resistance: ProRox ® Rocktight is
resistant to numerous chemicals.
Expansion joints: fit expansion joints to
accommodate expansion of the ProRox ®
Rocktight material and the steel pipe.
1.2.6 Pipe hangers and pipe supports
There is a wide range of solutions for pipe
hangers and pipe supports. The following
illustrations show the possibilities described
below for insulation systems:
Pipe hangers in direct contact with the piping
Pipe supports in direct contact with the piping
Pipe supports not in direct contact with the
piping (commonly used with cold insulation
systems)
A basic rule applying to all pipe attachments is
that the insulation system (e.g. the insulation and
cladding) must not be damaged if the piping
expands. Damage to the cladding of outdoor
installations, in particular, can allow the ingress
of moisture in the material. The result may be
permanent damage of the insulation system
and as a consequence high heat losses,
dangerously high surface temperatures and
corrosion etc.
