These design guideline 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 alwaysbe guaranteed for the service selected by the manufacturing vendor, but these guidelines will greatly reduce the amount of upfront 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.

These design guideline 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 alwaysbe guaranteed for the service selected by the manufacturing vendor, but these guidelines will greatly reduce the amount of upfront engineering hours that are required to develop the final design. The guidelines are a training tool for young engineers or

FLARE SELECTION AND SIZING( ENGINEERING DESIGN GUIDELINE) Q4+F K??R
These design guideline 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 alwaysbe guaranteed for the service selected by the manufacturing vendor, but these guidelines will greatly reduce the amount of upfront 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.
