Samenvatting

1. Summary
The goal of the graduation thesis is to develop a method to analyze the energy losses through pipe shoe supports. The end result will be an excel file that can be used by any of the engineers within Jacobs. Therefore all calculation and fundamental data must be included. To achieve this goal the following steps have been undertaken.

1.1. Scope definition
The scope has been defined to cover a range of supports that fall within the common practice. The
temperature range is set from 0[C] to 500[C] because this is applicable for 90% of the projects. The
pipe sizes range from 4[Inch] up to and including 20[Inch] pipes, with 3 different insulation
thicknesses:
· 50[mm]
· 60[mm]
· 70[mm]
Also two different solutions that reduce the heat loss will be assessed. The first is a solution that
thermally separates the support from the pipe. The second thermally separates the support from the
steel structure.

1.2. Theoretical basis
A theoretical basis is formed to understand the principals that govern the heat loss. The heat loss is
approached as the sum of three sub systems:
· Heat transfer through a multi layered pipe.
· Conductive heat loss through the pipe support
· Convective heat loss through the pipe support

1.3. Finite element calculations
To generate accurate result finite element calculations have been performed for all support solution
within the scope of work. The data is analyzed and equation are formulated that can be used to
quickly assess all support solutions within the scope of this thesis.

1.4. Financial analysis
Due to the large scope definition a generic statement cannot be given. However the excel file created
quickly generates the result required to make a finical analysis specific to the situation at hand.

1.5. Conclusion
Energy losses up to 900[W] per shoe are possible, for 25 supports this represents cost figures of
approximately €10k per year. It is advised to further investigate the value of the thesis and economical
benefits on actual and current projects.
