1. SCOPE This information stand../;! outlines the selection and design proce-
dures for thermal insulation, and discusses some of the considerations
governing successful performance of insulation.
. . .crystallization or other deposits on the walls.
. . .viscosity changes or product degradation.
. . .vaporization losses (in cold service).
2. DESIGN PROCEDURE The essential steps in thermal insulation selection and design are:
(1) Determine whether insulation is
required (Par. 3).
- ..
(2) Obtain.application data (Par. 4).
(3) Select appropriate insulation material (par-.,5)-.i - ^ - -
(4) Determine how much insulation is required (Par. 6).
(5) Verify material selection, select
barrier materials for.a complete system (Par. 7).
(6) Properly identify final selection
on drawings, in schedules, and in ; summaries.
(7) Establish construction details (See K11.4 standards).
3. INSULATION FUNCTION Thermal insula
tion simply reduces heat flux out of hot. c surfaces or into cold surfaces. Because it is expensive to install and maintain, insulation must pay for itself in at least
one of the following ways:
(1) Utility Conservation: Every heat flux represents a loss of energy. Most of these losses represent a cost increment in fuel, electrical power, cooling water, and o'ther utilities. - ... .
. (2) Equipment Economy: Unwanted heat losses may require oversizing heat exchangers, distillation columns,
pipelines, etc., simply to make up for the loss' - which may in some cases be a significant fraction of* process heat flux. (The alternative to oversizing may be yield loss or product degradation from excessive heating and/or pressure drops in
the equipment.)3
(3) Process Protection:- Heat flux requires temperature gradients in equipment walls and -fluid contents. Undersirable effects of these
gradients may include: ______ aj.Si;
(4) Fire Protection: Insulation may ' serve the primary or secondary purpose of protecting equipment and structures from early loss of strength during a fire - at least long enough to permit fighting the fire to bring it under .control., ,,__ _ .
(5) Personnel Protection: Where the fore going considerations call for no insulation, or not enough, insulation must be added only in those areas where operating and maintenance personnel are likely to contact the hot surfaces. (See Par. 5.1.6) .
,(6) Insulation and Plant Protection: In cold service,,insulation must be thick enough, regard less--of the above consi derations, to prevent deterioration
- and premature failure due to moisture attack. In "chilled" service insula tion may be required to avert the housekeeping and maintenance expenses
,, resulting from sweating and dripping. This requirement is most likely to apply in controlled environments.
3.1 Noise Control'" "The* use of insulation materials to absorb noise emitted from piping and equipment is a specialized subject not covered in this Selection Guide. Consult an expert in the noise control field.
4. APPLICATION DATA Prior to selection of insulation, the following kinds of data should be compiled to minimize the risk of picking an insulation system in the dark:
(1) Surface temperature range (Use tempera ture of contents unless a different temperature can be reliably specified. Note any rapid or extreme temperature
...fluctuations or cycling. For low - - temperature applications, determine
whether the aystea will be heated under some, circumstances, and list the maximum as well as minimus temperature!
(2) Limits on permissible heat flux.(These are process-imposed requirements which
, should be in performance data. In most instances no specific limit will be imposed,)
(3) Critical temperature limits. (Same considerations as in. Item (2) above.)

(4) Critical environmental conditions.
(These are normal temperature and
relative humidity, indoors. Outdoors, the critical conditions for hot and cold services are discussed in Par. 5.1.1 thru 5.1.6 Consider possible wind damage.)
(5) Operating department data. (Consider
fire hazard, possible leakage of
flammable materials info-insulation,
washdown practices, possibility of
hose stream impact during a fire,
etc. Consider also possible abuse:
foot, vehicle traffic, vibration,
mechan ical shock .)
----- ---
(6) Economic data. (See normal values in T4.9 STD 2, List 8. These factors are required to choose economic insulation thickness. Actual eco nomic-values, if available, may be substituted for normal factors.)
5. INSULATION MATERIAL SELECTION Assuming a preliminary determination has been mads that insulation is required, refer to Table I, entering at the appropriate surface temperature range. Observe remarks on Use and Limitations, if a Table II reference is given, review the general considerations "irrPaTT '5.i"before selecting an insulation material. The preferred (bold-face) mate rial will be the most economical selection unless one or more general considerations forces an alternative selection.
It is recommended that all insulation selec tions be reviewed at an early project stage with the Thermal Insulation specialist. ,$h process -will be more efficient, and considerations can be evaluated-on a broad basis of experience.

have a decisive effect on performance, safety, or economy. The preferred (bold face) insulation material should be selected unless application data developed in Step 2
(par. 4) indicates another choice.
5.1.1 Thermal -Performance ^ The key
consideration is thermai-conducfTvity (tabulated here for a single representative
temperature). Stability of this value with respect to age, moisture content, etc., is noted. Maximum temperature limits are given,
where significant. For infrequent cases where specific heat, diffusivity, or thermal shock limitations may apply, see Kll.l STD 3.
5.1.2 Chemical- interactions Ther-e three types of interactions
;;
(1) insulation material affects insulated surface.
(2) process contents deteriorate insulation.
(3) .flammable xontents'are"degraded , by insulation (Spontaneous
combustion risk). ,,_t
A number of insulating materials can release halides enough to cause stress corrosion ' cracking of austenitic stainless alloys. These are noted. Any alkaline insulation
can attack aluminum, especially when moist.
Nearly all insulations are attacked by
strong acids and alkalis. No special note
is made, since most of surroundings are also
attacked. Special note is made where'sol
vents deteriorate the insulation.
' ' '"
sifters, and h-overs, chutes, or ducts fitted with vibrators :c facilitate bulk material flow.
Materials of h;-:'-; compressive strength are
first choice w>ore vehicle damage or foot
traffic,.must be reckoned with. Top heads
Of vessels "With agitators usually require
consideration. Insulation used to support
flat bottomed vessels must be of high com
pressive strength.
._
5.1.4 Economics Systems offering the lowest installed cost for a given heat flux are listed in bold-face type. Others are selected only where process or performance .considerations are over-riding.
5.1.5 Moisture Problems Most types of insulations, except those with closed-cell construction, have high water absorptivity. For elevated temperature service, the barrier system must be permeable enough to vent moisture vapor, yet resist passage of liquid water. For low-temperature service moisture in,all.forms must be. excluded,by an imperme able barrier, and the barrier must be mechanically durable. Low-temperature lines should always be located above-grade or in service tunnels if feasible. Hightemperature lines may be routed above-grade or well-drained, ventilated trenches or tunnels. High-temperature lines insulated fpr direct burial represent a specialized problem not covered by standards.
"5.1:6 Safety Considerations One safety hazard' is'mentioned in'Pair. 5.1.2. This is not a major risk. Others, more often encountered are:
Cases have _been reported in which flammable
1 iqu id" leaka"ge*Thas. been- absorbed by insula
tion. Later, when hot insulation was
breached for repair work, flames were noted.
Contributing factors have not all been
identified, but it may be prudent to avoid
some insulation materials on lines and
equipment containing flammable liquids in
areas classified as Division 1 with respect
to electrical installations'.
~
5.1.3 Mechanical Durability In some applications the completed insulation system must'Withstand-unusual loadings or possible abuse. If a mechanically durable insulation cannot be used, shielding or guarding may
be necessary.____________________________
Wind forces impose special"support and attachment requirements in applications' where uplift or suction can become signifi
cant. Loads on barrier membranes may be
particularly hard to sustain.
Vibration and mechanical shock loadings also impose special support and attachment prob lems, particularly on rotary dryers or
blenders, oscillating equipment such as
(1) Fire damage protection
(2) Safe surface temperature
(3) Toxic contamination
The first problem is significant if it is determined that equipment or piping requires protection (time delay) from high temperature "Of a .fire, and the thermal insulation is relied'on for part or"a11 of this protection. In such cases, ability of the insulation system to withstand heat effects and mechan ical impact of water hose streams will be major considerations in selection. Aside from designing insulation for fire protection it will be desirable in some cases to avoid insulating"materials which 'have a high flame spread index, or will add fuel to the fire.
The second consideration applies mainly where people can contact the insulation inadvert ently (c.g., unprotected skin of back or "upper arms) T'"informal experiments indicate that painted metal surfaces or painted metal insulation jackets should be limited to 140 F max. in areas of personnel exposure. Bare unpainted metal should be held to 130 F.

Non-metallie pip.r.q and insulation surfaces can b permitted up to 160 P. Metal sur
faces in areas ov low hazard and infrequent
personnel contact ~(e.g.-, yard, piping near '-- grade and storage tank farms) can be per
mitted to reach 150 F. Surfaces above these temperatures should be -controlled by insula- --
tion only in areas where personnel' contact " is reasonably likely. (If portable ladders or scaffolds are needed for access, tempo rary safeguards may be provided at that
time).
The final hazard - contamination of the
insulation by toxic leaks and spills -
must be dealt with on a case basis. Does
"the need to handle insulation aggravate an exposure problem? What disposal and
decontamination problems are involved? Should insulation be omitted - or per haps be provided with a barrier around. the installation?

ISSUE 4
date
1/85
PAGE 1 OF 18
1. SCOPE This information standard out lines the selection and design procedures for thermal insulation, and discusses some of the considerations governing successful performance of insulation..
2. DESIGN PROCEDURE The essential steps in thermal insulation selection and design
(1) Determine whethef^"Insulation is required (Par. 3).
(2) Obtain application data;(P|i|^ 4).
(3) Select ' appropriate/insulation mate
rial (Par. 5). " ,
"
(4) Determine how much insulation is required (Par. 6).
(5) Verify material selection, select
barrier materials for a complete
system (Par. 7).
-~
(6) Properly identify final selection on drawings, in schedules, and in sum
maries.
(7) Establish construction details (See K11.4 standards).
3. INSULATION FUNCTION Thermal insulation simply reduced heat flux out of - hot sur faces or into cold surfaces. Because it is expensive to install and maintain, insulation must pay for itself in at least
one of the following ways:
(1) Utility Conservation Every heat flux represents a loss of energy.
Most of these losses represent a cost increment in fuel, electrical
power, cooling water, and other utilities.
(2) Equipment Economy Unwanted heat losses may require oversizing heat exchangers, distillation columns, pipelines, etc., simply to make up for the loss - which may, in some cases, be a significant fraction of process heat flux. (The alternative to oversizing may be yield loss or
product degradation from excessive
heating and/or pressure drops in the equipment.)3
(3) Process Protection
Heat flux
requires temperature gradients in
equipment walls and fluid contents.
Undesirable effects of these gradi
ents may include:
. . .crystallization or other depos its on the walls. . . .viscosity changes or product degradation.
. . .vaporization losses (in cold service).
(4) Fire Protection
Insulation may
ser.ve. tne primary or secondary pur
pose - of protecting equipment and
structures from early loss of
strength during a fire - at least
. long enough to permit fighting the
fire to bring it under control.
(5) Personnel Protection Where the foregoing considerations call for no insulation, or not enough, insula tion must be added only in those
areas where operating and mainte nance personnel are likely to con tact the hot surfaces. (See Par. 5.1.6).
(6) Insulation and Plant Protection in
cold service, insulation must be
thick enough, regardless of the
above considerations, to prevent
deterioration and premature failure
due to moisture attack.
in
chilled" service, insulation may be
required to avert the housekeeping
and maintenance expenses resulting
from sweating and dripping. This
requirement is most likely to apply
in controlled environments.
3.1 Noise Control The use of insulation materials to absorb noise emitted from piping and equipment is a specialized sub ject not covered in this Selection Guide.
Consult an expert in the noise control
field.
4. APPLICATION DATA Prior to selection of insulation, the following kinds of data should be compiled to minimize the risk of
picking an insulation system in the dark:
(1) Surface Temperature Range Use tem
perature of contents unless a dif
ferent temperature can be reliably
specified.
Note any rapid or
extreme temperature fluctuations or
cycling.
For low temperature
applications, determine whether the
system will be heated under some
circumstances, and list the maximum
as well as minimum temperature.
(2) Limits on Permissible Heat Flux These are process-imposed require-
, ments which should be in performance
data. In most instances, no spe
cific limit will be imposed.

5. INSULATION MATERIAL SELECTION Assuming a preliminary determination has been made that insulation is required (refer to Table I) entering at the appropriate sur face temperature range. Observe remarks on Use and Limitations. If a Table II reference is given, review the general considerations in Par. 5.1 before select ing an insulation material. The preferred (bold-face) material will be the most eco nomical selection unless one or more gen eral considerations forces an alternative selection.
It is recommended that all insulation selections be reviewed at an early project stage with the Thermal insulation Special ist. The process will be more efficient, .and considerations can be evaluated on a broad basis of experience.

8. BARRIER SELECTION The Thermal insula tion System Specifications contain barrier materials identified by symbols. The sym bol identifies the major material of con struction for the pipe or vessel and, in addition, identifies minor materials of construction for fittings, valves, pumps, etc. The symbols and corresponding bar rier materials are listed in Table IV. The use and application of the barrier symbols for drawings and schedules are described in Kll.l STD 2.
Table V. Barrier Materials shows selective barriers for the Thermal Insulation System
Specifications. The tables are developed
based on available manufacturer's stan dards and typical usage for pipe, equip ment, and duct work. A numerical cost index is shown which compares cost of the various barrier systems for each Thermal
Insulation System Specification. The low est cost barrier is identified by number "l*, and as barrier cost increases, numer als increase. The cost index is a rela tive guide only and should not be used for
direct cost comparison. Select the lowest cost barrier for which an "X" appears in the columns representing the particular design conditions.

3. DEFINITIONS OF TERMS Terms used in this
standard have the following definitions:
V " Heat flux, Btu/hr, s<j ft, from bare steel surfaces.
Q -Heat flux, Btu/hr, sq.ft,-at equipment or
pipe surface beneath the insulation.
q " Heat flux, Btu/hr, sq ft, at outer surface of
insulation.
-
--
/, " Temperature, F, of the hot or cold surface
to be insulated.
ta " Temperature, F, of air surrounding the insu lation (ambient).
ts " Temperature, F, of the outer surface of
insulation.
" 4
A/, " /, -- ta for elevated temperature service,
m ta~ t, for low temperature service.
" ts " ta fr elevated temperature service, m ta- ts for low temperature service.
RH " Relative humidity of ambient air.
R " The sum of resistances, hr, sq ft, F/Btu,
throughthe insulation and' the air film surrounding the insulation, e.g., --x + --1
KO
for flat surfaces.
C " Convection coefficient,"' Btu/hr/sq ft,-F,
used to estimate resistance through the. air
film surrounding the insulation.
-- " Internal resistance of a single thickness of insulation over a flat surface; x - thickness of insulation, in inches; k " conductivity of the insulation, Btu/hr, sq ft, in., at the
mean temperature - * a -
-jp " Internal resistance of a single thickness of
insulation over a cylindrical surface; y ~ effective thickness of insulation; ' k is . defined above.
NOTE: Where the sum of internal resist ances of insulation in double layer or
d " Inside diameter of either the inner layer or outer layer of insulation, inches.
4. CONVECTION COEFFICIENTS An adequate treatment of convection coefficients is not within the scope of this standard. The following coeffi cients (expressed as C and defined above), are suggested for use in heat transfer equations:
4.1 Flat Surfaces The value of C for flat surfaces in still air at elevated temperatures may be con sidered 1.39 for vertical plates, 1.79 for horizontal plates facing upward, and 0.89 for horizontal plates facing downward.
The value of C for flat surfaces in still air at low temperatures - may be considered 1.39 for vertical plates, 0.89 for horizontal plates facing upward, and 1.79 for horizontal plates facing downward.
4.2 Cylindrical Surfaces The value of C for cylin' drical surfaces in still air, at both elevated and low
temperatures, may be considered 1.6.
The value of C for cylindrical surfaces in air moving at 2 miles per hour nominal velocity, at both ele~ vated and low temperatures, may be considered 1.77. --The effect of air, moving at higher velocities is indicated in Table II, but exact coefficients are not given. - ------- - -
5. HEAT TRANSFER CALCULATIONS Heat trans
fer calculations presented in this Standard do not
cover personnel protection at elevated temperatures
or prevention of surface moisture condensation at
low temperatures.
Thicknesses of insulation
adequate to meet these design conditions have
been calculated from equations based on the insula
tion surface, and are presented in tabular form
in each of the Materials Specifications for insula
tion. There is no point in repeating these equations
here.
_l(
*.compound systems is expressed as fi. +
for flat surfaces, and

cylindrical surfaces, xt and yt. always represent the inner layer of insulation, x2 and y2 always represent the outer layer; k, and kj are selected to suit the materials and mean temperatures indicated by x,, ylt x, and ya.
Equations in this standard are based on the hot or cold equipment surface beneath the insulation, and are provided for use when control of process tempera ture and heat flow is the governing design factor.
5.1 Flat Surfaces The equation for calculating heat flow through a single layer of insulation over a fiat surface is:
Q (1)
D0 - Outside diameter of the outer layer of insulation, inches.
D " Outside diameter of the inner layer of insulation, inches.
Dp m Outside diameter of pipe or equipment, inches.
The value of k is determined from Figures 2, 3, and 4; the value of C is suggested in Pat. 4.1. Fot increased heat loss due to wind velocity conditions, multiply q by conversion factors in Table II.

Where more than one layer of insulation is applied over a flat surface, the equation becomes:
K11.1 STD 4
ISSUE 1 jRAGE 3 OF 16
The value of y is given in Table V. The value of k is determined from Figures 2, 3, and 4. The value of C is suggested in Par. 4.2. For increased heat loss due to wind velocity conditions, multiply Q by conversion factors in Table II.
5.2 Cylindrical Surfaces Cylindrical insulation or pipe covering offers a path of varying-area-for-the flow of heat, and equations are more complicated than for flat surfaces. The classical mathematical treatment utilizes a log mean area for the transfer of heat.
By suitable rearrangement of terms, it is possible to
calculate heat flux both on the basis of the external
surface of the insulation, and on the basis of the
pipe or equipment surface diameter. In practice,
there are uses for both methods of calculation;
however, only the pipe or equipment-surface: basis is
covered in this standard.
...
Note that while heat fluxes q and Q are equal for flat surfaces, this is never true for cylindrical surfaces.
Where more than one layer of insulation is required, or the variation of k with temperature is large and it is desirable to treat the insulation as consisting of layers of varying heat resistance, the equation becomes:

dividing the heat flux for the external surface of the
pipe, or equipment by C to obtain the temperature difference:

5.3 Calculations for Cylindrical Surfaces Equations are based on the pipe or equipment diameter which does not vary -with insulation thickness. Calcula tions are intended to provide the rate of heat loss -or gain from or into the process fluid at the pipe or equipment wall. ---- ------------- ------ ----TM-------------
Equations (1) and (2) still are applicable as long as the heat flow area or the effective thickness of insulation are adjusted to suit a cylindrical object. The common method used for this adjustment is the calculation of an effective insulation thickness, y, which takes into account the variable area in the heat flux path,
5.3.1 Calculation of y The following equation defines y:
y- 1.1513 Dp log \~\ ;

From Paragraph 3, "Definitions":' A/j /s - ta for elevated temperature service;
" ta -- ts for low temperature service. Substituting in Equation (6):

This alignment diagram has been reprinted directly from the current edition of the ASHRAE GUIDE, and there is no record of results from actual field use. However, recommended thicknesses are within the range of those actually calculated and appearing in the Materials Specifications, and the approach seems adequate for the practical solution of problems.
