API 7-1 Oilfield Drill Pipe Tool Joint
• Minimum Yield Strength = 120,000 psi
• Minimum Tensile Strength = 140,000 psi
Because tool joints are added to drillpipe, the weight of given to pipe in many tables is the “nominal weight”. The exact weight will require adding the weight of the tool joints to the tubing portion. Since two joints do not weigh the same, it is difficult to determine the weight of a joint of drillpipe and so an “approximate weight” is used in many calculations.

The tool joints on drill pipe may contain internal and/or external upsets. An upset is a decrease in the ID and/or an increase in the OD of the pipe which is used to strengthen the weld between the pipe and the tool joint. It is important to note that under tension, the tool joint is stronger than the tubular
