1.2 Insulation of piping
Selection of pipe insulation systems
Generally, the best insulation is achieved using
ProRox
® Pipe Sections. The preformed sections
are quick and easy to install. Their excellent fit
and high compression resistance means pipe
sections can be applied in a single layer without
any additional spacers. They also have a lower
insulation thickness. Pipe wraps (mats), are
usually applied for the insulation of large pipe
diameters and can be applied to shaped pieces
like elbows and T-joints.
Comparison
ProRox ® pipe sections and pipe wraps (mats)
offer the advantage that spacers are generally
not required.
ProRox ® pipe sections and pipe wraps
(mats) are applied more quickly without the
inter ference of spacers.
Both products offer an even, firm surface
for installing the cladding.
The lack of spacers creates lower heat loss.
It yields an even surface temperature
across the cladding.
In comparison to wired mats, a more
shallow insulation thickness can be used.
With a same insulation thickness, the
operational costs of the installation
decrease as a result of lower heat losses.
Generally speaking, a spacer or support structure
functions as a thermal bridge, as a result of which
the heat loss in the total insulation is increased
considerably.
The design of an insulation system depends upon
many factors such as the dimensions, mechanical
loads, safety aspects, economics, etc.
Consequently this also requires a considered
selection of the insulation material.
