Evaluating
Installed Cost Of Corrosion Resistant Piping |
 |
This
course provides information of interest to engineers and specifiers who
select materials for corrosion–resistant piping systems. |
|
|
Analyzes
three typical piping systems in six different pipe sizes and a variety of
materials —metallic, non–metallic, composite and lined. |
|
|
Summarizes
the comparative costs. This course illustrates the need to consider the
large number of factors which influence studies of installed cost. Hence
it will enable the reader to make realistic use of the information
presented here. |
|
|
Itemizes
a nine–step approach to selection of piping materials. |
|
|
Supports
its conclusions with complete cost calculations presented in both digital
and graphic form. |
|
|
Highlights
and seeks to correct the inconsistencies which have limited the usefulness
of earlier studies on this topic, in particular : |
|
|
|
The pitfalls of inappropriate examples and assumptions |
|
|
The bias introduced by estimating tables used in determining labor costs |
|
|
The critical effect of labor costs on estimates of installed cost |
|
|
The difference between estimated and actual installed costs of corrosion
resistant piping systems |
|
|
The limitations of even the best cost estimates as decision–making tools
in piping material selection. |
