BBSCHICO'S PIPE FITTER'S POCKET CARDS

This set of cheat cards should be a must for every man and woman working construction it has loads of great information in a small package from pipe and fitting sizes to take offs for treaded pipe to bolting charts for large bore series a and b flanges with a butterfly bolt chart.
