- Heavy weight drill pipe is a medium-weight drilling pipe, (referred standards in API SPEC 7-1). It has bigger wall thickness than common drilling pipe and smaller than drill collar.
Application:
- Oil And Gas Well Drilling
- Oilfield Drilling
- Mine Blasting
- Water Well Drilling
- Geothermal Wells Drilling
- Fore Poling
- Coal And Nonferrous Metal Mining Projects
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 pipe is a steel pipe with thread at the end, which is used to connect the surface equipment of the drilling rig to the drilling and grinding equipment or the bottom hole equipment at the bottom of the drilling. Drill pipe can be divided into three categories: kelly, drill pipe and heavy drill pipe.
Drill collar is located at the bottom of the drill string and is the main component of the lower drill tool assembly. Its main feature is that the wall thickness is larger, and it has greater gravity and rigidity. In order to facilitate tripping work, elevator grooves and slip grooves can be processed on the outer surface of the inner thread of the drill collar. Drill collars are generally divided into three types: spiral drill collars, non-magnetic drill collars, and integral drill collars.
