ENGINEERING DESIGN GUIDELINES
Checked by:
Karl Kolmetz
These design guidelines are believed to be as accurate as possible, but are very general and not for specific design
cases. They were designed for engineers to do preliminary designs and process specification sheets. The final
design must always be guaranteed for the service selected by the manufacturing vendor, but these guidelines will
greatly reduce the amount of up front engineering hours that are required to develop the final design. The guidelines
are a training tool for young engineers or a resource for engineers with experience.
