Heavy Weight Drill Pipe

Heavy Weight Drill Pipe (short for HWDP) is the industry standard for an intermediate weight drill stem member and is available in standard, spiraled and non-magnetic designs making it useful in a number of applications. It has drill pipe dimensions for easier handling. Heavy weight drill pipe utilizes a center upset or wear pad to increase tube life, reduce hole drag and minimize differential sticking problems. is an intermediate weight drill stem component which is used in conjunction with the drill pipe and drill collars.
Features of Heavy Weight Drill Pipe
Extra-length tool joints provide ample space to recut the connections, reduce the wear rate on the OD and extend service life.
The center upset protects the tube from OD wear by keeping the tube away from the hole wall, while at the same time reducing the risk of differential sticking.
The API boreback box stress relief feature is standard for the box connection on 4” Heavy Weight Drill Pipe and larger, helping to extend the service life of the connection.
Cold rolling the thread roots on all Heavy Weight Drill Pipe connections increases the connection’s ability to resist fatigue cracking.
Heavy Weight Drill Pipe can be picked up with the drill pipe elevators, for fast and efficient handling on the rig floor.
Application
Directional Drilling:
An effective weight-on-bit member in extended reach, horizontal and conventional directional well designs.
Improved directional control by reducing torque and drag.
The center upset helps reduce the risk of differential sticking.
Vertical Drilling:
Use as an active weight-on-bit member.
Heavy Weight Drill Pipe can be used to provide a portion of the anticipated drilling weight when using soft formation PDC rock bits.
