Insulation of piping
1. System solutions
1.2 Insulation of piping
Piping plays a central role in many industrial
processes in chemical or petrochemical
installations such as power plants, as it connects
core components such as appliances, columns,
vessels, boilers, turbines etc. with one another
and facilitates the flow of materials and energy.
To guarantee a correct process cycle, the
condition of the media within the pipes must
remain within the set limitations (e.g.
temperature, viscosity, pressure, etc.). In addition
to the correct isometric construction and
fastening of the piping, the piping insulation also
has an important function. It must ensure that
heat loss are effectively reduced and that the
installation continues to operate economically and
functionally on a permanent basis. This is the only
way to guarantee the maximum efficiency of the
process cycle throughout the design service life
without losses as a result of faults.
Requirements for industrial piping
The basic efficiency and productivity factors of
piping for the processing industry include: energy
efficiency, dependability and reliability under
different conditions, functionality of the process
control, appropriate support structure suitable for
the operating environment, as well as mechanical
durability. The thermal insulation of piping plays a
significant role in fulfilling these requirements.
thermal insulation
The functions of proper thermal insulation for
piping include:
Reduction of heat losses (cost savings)
Reduction of CO² emissions
Frost protection
Process control: ensuring the stability of
the process temperature
Noise reduction
Condensation prevention
Personnel protection against high temperatures
ProRox ® products for pipe insulation
ROXUL Inc offers a wide range of high-quality stone
wool insulation products for the insulation of
industrial plants. These products are part of our
extensive ProRox
® range for industrial insulation.
With this specific field of application in mind we
developed our pre-formed pipe sections and pipe
wrap (mat) products for pipe insulation. All these
products are easy to install and contribute to a high
level of efficiency, functionality and reduced heat
losses. Continuous internal and external inspection
and high levels of quality assurance ensure the
consistently high quality of all ROXUL
® products.
The examples of use below cannot fully take into
account the particular circumstances of the
construction-related factors. Determine whether
the products are suitable for the corresponding
application in each individual case. If in doubt,
consult the ROXUL Technical Services Team.
The applicable standards and regulations must
also be observed. A few examples follow:
NACE SP0198 (Control of corrosion under
thermal insulation and fireproofing materials - a
systems approach)
MICA (National Commercial & Industrial
Insulation Standards)
DIN 4140 (Insulation works on technical
industrial plants and in technical facility
equipment)
AGI Q101 (Insulation works on power plant
components)
CINI-Manual “Insulation for industries”
BS 5970 (Code of practice for the thermal
insulation of pipework, ductwork, associated
equipment and other industrial
installations)
