1. Introduction Sheet No. 1 of 1

These notes are intended to help designers follow normal design practices, and further reach an optimum

design.

2. Notes

Flange

The procedures are from Taylor Forge Bulletin No. 502, 7th Ed., " Modern Flange Design ".

In general, bolts should be used in multiples of four(4).

For large diameter flanges, many smaller bolts on a tight bolt circle are recommended to reduce the f lange

thickness.
