Thermal Insulation Calculation Software

How much operating profit are you wasting through inappropriately specified plant insulation?

Are you spending too much time just calculating the thermal insulation requirements of the plant?

Are you confident that the approach you have taken incorporates the knowledge of renownedinsulation experts?

You can save days of design time per year and have real confidence in the result if you use TICPin all your thermal insulation problems

TICP (Thermal Insulation Calculation Program) is a new software product that allows you to simulate a widerange of thermal insulation problems via a flexible Windows™ interface. It was developed on behalf of, andwith the assistance of the Netherlands based CINI organisation – CINI provides expert guidance throughoutEurope on practical and design issues that must be addressed when applying insulation materials to plant,and is an acknowledged source of authoritative information in this field.TICP encapsulates the knowledge of CINI’s “Insulation for Industries” referencebook which contains numerous examples of insulators’ thermal properties,and the recommended thickness of insulators that should be applied.TICP will perform a range of simulations that will be of use when tacklingplant design or analysis tasks. These include:

• Determine the optimum insulation thickness to (forexample) minimise plant costs or prevent surfacecondensation.

• Simulate and give profiles for cooling of flowing orstagnant media.

• Examine thermal properties (including calculationof mean from actual conductivity) of insulators.

• Summarise financial implications of various aspectsof insulator usage.

TICP comes with a pre-defined database coveringmaterials from the CINI handbook; you can extendthis database as and when required. Insulation prices– used by the various financial analysis options withinTICP – can also be added and updated as required,and entered in the currency of your choice from Euroto $. Context-sensitive help is available throughoutTICP and covers all aspects of its uses, from general concepts down to the meaning of each on-screenelement. It has its own user interface for the entry of data, and presents results as graphs or tables and theseresults can be copied into other programs via the Windows clipboard.

TICP enables you to simulate a wide range of thermallyinsulated systems. TICP handles these via 3 main categories.The “case-by-case” category, allows you to calculate thedetailed thermal behaviour of a specific section of piping.

TICP’s “general applications” category allows you tocalculate the insulation thicknesses required for a wholerange of pipe sizes if you must meet some overall objective,such as minimising the combined operating and insulationcosts, preventing condensation (when you are insulatingpipes containing a cold fluid) and (for hot fluids) keepingthe surface temperature of pipes below some limitdetermined by safety standards. “Auxiliary calculation” isused for specific isolated calculations.The following example illustrates how TICP calculates theinsulation thicknesses necessary to keep the surfacetemperature of an (insulated) pipe below some threshold.From the general applications category “PersonnelProtection” is selected as the calculation of choice on TICP’s“Problem Page”; the other pages then adjust their contentsso only values applicable to this problem can be entered.

In the first (“Product Side”) page the details of the fluidflowing through the system are specified. You can entervalues on this page (and any other) in either metric or UScustomary units.The second input page allows you to enter values for theatmosphere surrounding the system you’re simulating; airtemperature, speed and the convection model to be usedto determine this form of heat loss. TICP supports a rangeof standard models, including ISO/DIS 12241.2, VDI 2055and ASTM C 680.Finally, on the construction page the mechanical details ofthe piping and insulation are input. In this case the“standard” CINI 2.1.01 insulator from TICP’s database isused, but you can enter a specific thermal conductivity, oradd a new insulator with more complex thermal propertiesto the database if you wish.Once all the necessary data has been entered you arepresented with the results page containing a grid of results;along the top there are the inlet temperatures you specifiedon the “Product Page”, and down the left the standard“Nominal Diameter” (DN) outside diameters of pipe youmay be using. Each cell contains the insulation thickness

you must use to satisfythe safety threshold fora particular inlett e m p e r a t u r e / p i p ediameter combination.For this example the left column’s values are all “None”, asfor this column’s operating temperature (50°C) the fluid isalready below the safety threshold (65°C) - no insulation isnecessary. A double click on any cell will switch to thedetails page relating to that cell. This shows the details ofheat loss and various heat transfer coefficients, for boththe insulated pipe and (for comparison) the same pipewithout any insulation.

System requirementsIt is recommended that TICP is used on a Pentium withat least 32MB RAM, operating under MS Windows NT or95/98. The software is network compatible and year 2000compliant.
