Removable Thermal Insulation Covers
1. Introduction
Removable thermal insulation covers are used to cover heaters,
processing pipes, valves, flanges, instrumentation panels, and
other components. Unlike permanent hard insulation, soft insulation
covers have the advantage of being removable and reusable, making
them the insulation of choice for components that need to be
accessed from time to time for maintenance and inspection.
While removable thermal insulation covers are typically one of the
last items to be installed before a facility goes into production,
they are a critical component when it comes to site safety and
system stability.
Heaters, pipes, valves, flanges, and other components left
uncovered can result in:
Unnecessary process adjustment due to heat loss.
False readings or alarms being sent to the control room.
Equipment failures due to operation outside of normal temperature
ranges.
Degradation of product quality due to improper process
temperatures.
Process piping and equipment left without a properly designed
thermal insulation cover can freeze and fail to properly operate.
2. Benefits
Heat retention and freeze protection.
Personnel protection against burns from hot components.
Energy savings from reduced heat loss to surrounding environment.
Sound attenuation.
Insulation is easily removed and replaced to allow for maintenance
and inspection.
3. Construction
Removable insulation covers are typically constructed in 3 layers.
The photo below illustrate the construction used in a standard
removable insulation cover. Note that for different demanding and
unique applications, GME offers a wide range of materials and
construction.
Fastening methods include straps, lacing wire, cords, buckles, and
Velcro.
Removable insulation covers feature high temperature sewn
construction and incorporate flaps, closures, and cutouts to
provide easy access to ports and controls.
