Commercial Solutions - Pipe and Vessel Insulation

Plasti-Fab insulation is excellent for insulating cold environments, such as
pipes and vessels containing cold liquids or gases at temperature from
normal room temperature down to and including cryogenic temperatures
- i.e., below -100 °C (-150 °F). Properly shaped insulation coverings
efficiently control condensation and heat transfer.

At cryogenic temperatures, extreme care is necessary to ensure that
vapour barriers are complete and adequate. PlastiSpan insulation is not
suitable for insulating environments which will be maintained at heat
service temperatures greater than 60 °C (140 °F).

Insulation can be used to protect the contents of the pipe or vessel from the
effects of a freezing exterior temperature. Examples of this application would
be utility and sewer lines buried in an area where the ground temperature
will be below freezing or which are exposed to the weather for other
reasons. Methods for accomplishing this are dealt with the Plasti-Fab
brochure 'Utilities Insulation'.

Plasti-Fab fabricates PlastiSpan insulation for pipes and vessels to provide
maximum thermal efficiency, maximum physical properties and maximum
economy to suit the requirements of the application. PlastiSpan insulation
is a lightweight insulation which is easy to handle, ship and install.

Pipe and vessel coverings are fabricated with a butt joint or an optional
tongue and groove longitudinal joint. A factory applied foil jacketing can be
supplied to most pipe coverings or to vessel coverings in order to provide a
vapour barrier.
