1.4 Insulation of columns
Insulation systems for columns
Selection and installation of the
insulation
Selecting the appropriate insulation depends on the
operating method, the installation temperature, the
dimensions and the location of the vessel or
column.
Insulation materials such as ProRox ® are suitable
for use of the insulation of columns.
Since columns are often located outdoors, it is
important to select insulation with a low thermal
conductivity and excellent water repellent
properties. The insulation is usually fastened to
the columns with steel straps. These should be
made from stainless steel and should be closed
with butterfly nuts or quick release fasteners. The
strap measurements and intervals for cylindrical
objects shown in the table on the next page have
proved useful in many projects.
