Appendix
B
API Drill Collar and Drill Pipe Properties
This appendix gives the basic geometric and physical properties of API drill
collars and API drill pipe.
B.1 API Drill Collars
Table B-1 gives the dimensions and weight per unit length for API drill collars.
Table B-2 gives the possible rotary shoulder connections and recommended make-up
torque for the various drill collar sizes with API connections.
B.2 API Drill Pipe
Table B-3 gives the dimensions and the weight per unit length for the API drill
pipe body. Table B-4 gives the dimensions of the tool joints, actual weight per unit
length, and mechanical properties for new Grade E drill pipe. Table B-5 gives the
dimensions of the tool joints, actual weight per unit length, and mechanical
properties for new Grades X, G and S drill pipe (known as high strength drill pipe).
Table B-6 gives the API rotary shouldered connection interchange list.
