Length Ranges of Drill Pipe:
Range 1: 18 ft. to 22 ft.
Range 2: 27 ft. to 30 ft.
Range 3: 38 ft. to 45 ft.

Types of Drill Pipe:
Drill pipe
Heavy weight drill pipe
Tool joint
Pup joint

Drill Pipe:

Used to transmit power (torque and tension) and transport drilling fluid, connecting the ground drilling rig and the downhole drilling tools. Heavy weight drill pipe is a medium-weight drilling pipe, It has bigger wall thickness than common drilling pipe and smaller than drill collar.

Upset of drill pipe:
The upset (thread-end finish) refers to the wall of the tool joint at the threaded connection. Drill pipe is offered with an internal upset (IU), an external upset (EU), or an internal-external upset (IEU).
IU - In an internal upset increased thickness along the inside walls compensate for the metal removed in threading with a uniform, straight outside wall.
EU - In an external upset the increased thickness along the outside diameter of the tubing compensates for the metal removed in threading with a straight bore.
IEU - In an internal-external upset thickness is increased along both the inside and outside walls of the pipe to compensate for the metal removed in threading.

Drill Collar:

Used to provide bit pressure (WOB), stabilize the drill bit and prevent well deviation, located at the bottom of the drill string.
