Roxul Industrial Insulation Process - Manual (Page 33)

Installation
Before starting the insulation works, ensure
that all preparatory work on the object has been
completed. Refer to Chapter 1.1 for details.
The ProRox ® PS 900 Series pipe sections are
mounted directly onto the pipe to form a close
fit. With horizontal pipes, the lengthwise joint of
the pipe section should be turned towards the
underside at the 6 o’clock position. With vertical
pipes, the lengthwise joints should be staggered
at an angle of 30 ° to one another. Secure the pipe
sections with galvanized binding wire or with steel
bands. With an insulation thickness exceeding
5 inches (120 mm) [or temperatures > 550 °F
(300 °C)], install the insulation in at least two
layers. If the insulation is assembled in multiple
layers, the joints of the individual insulation layers
must be staggered.
Support structures and spacers
Spacers are not generally essential in insulation
systems with pipe sections. With pipes that are
exposed to large mechanical loads (e.g. strong
vibrations) and/or temperatures above
550 °F (300 °C), determine whether a spacer ring
is required in each individual case.
With pipes that have been installed vertically,
with a height in excess of 13 feet (4 m), fit support
structures to transfer the dead load of the
insulation system onto the pipe. Attach the first
support ring to the lowest point of the vertical
pipe. The distance between the support rings
should not exceed approximately 13 feet (4 m).
