The Author : has spent the greater part of his life working in the pipe trade. Through his many years of experience he has learned to appreciate the time saving value of having calculated tables for pipe bending, piping offsets, miter turn fittings, welding elbow offsets, fabricating odd angle elbows from 90 degree welding elbows, solving angles with a steel square, and so on. These tables eliminate the calculating of these problems and thereby prevent occasional errors. This book has been made small enough for the user to carry it around in his pocket so that he may consult the book whenever the need arises.
