HSCO - 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.
Standard: API 5DP/ API 5D
Grade: E-75, X-95, G-105, S-135
Application: For well drilling
Out Diameter of Drill Pipe:
From 2 3/8” to 6 5/8″
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
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.
Drill Collar:
- Standard: API SPEC 7-1
- Size: 3-1/8" to 12"
- Length: 30Ft / 32Ft / 43Ft / Range2~Range3
