This book was created to ease the mind and to simplify the use of offsets and angles to where the beginner as well as the novice pipefitter and welder will understand how easy it is to layout and understand how to calculate offsets and angles. This book will help you understand the everyday tasks of pipe fabrication. On each page I walk you through step by step and show you the formula's for calculating that type of offset. This way, if you have an odd angle or offset that is not shown, you can calculate it with ease by using that same type of formula. This book is designed to help you understand how to layout common and uncommon angles and offsets. Pipefitting and fabrication of piping is basically simple, if you understand the concepts. This book is designed to help you understand these concepts.
