Downhole Motor
Heavy Weight Drill Pipe
Integral or Weld Heavy Weight Drill Pipe
Standard: API Spec 7
Specification: OD 3 1/2”, 4 1/2”, 5”, 5 1/2”
Material: AISI 4145H Alloy Steel and Non-magnetic material
Type: Integral and Friction welded
Usage: HWDP is the transition zone between drill collar and drill pipe. It can not only reduce stress-formation in the connection of drill collar and drill pipe, but also reduce the wear on OD.
★ Description of Integral HWDP:
Integral HWDP can easily solve problems arising in vertical holes in soft formation by replacing part of the drill collars. The advantages include:
1. Reduced torque in high-rpm, deep drilling.
2. Less trip time as compared to handling a long string of drill collars.
3. Fewer tool-joint connection failures.
4. Easy in handling and transporting to and from locations
5. Help for keeping direction of directional well.
HWDP's wear resistance hardbanding is standard on tool joints connections and central upset. Hardbanding is made by an automatic machine after preheating the pipe and is followed by stress relieving.
