Product Description

The heavy weight drill pipe provides a gradual transition from heavy, rigid drill collars to more flexible drill pipe, helping improve Bending Stress Ratios to accepted industry standards. BSR is used as an indicator of the suitability of a particular connection OD and ID.

The three-point contact profile reduces drag, and the center upset prevents excessive buckling. Heavy weight drill pipe placed between the drill collars and the drill pipe reduces operational risks related to fatigue in this stress-prone area.

JerryMetals' Integral HWDP also provides with two optional of hot forged or rolled processing. Futhermore, we can produce none standard HWDP according to our customer's various requirements.

Hardbanding
HWDP's hardbanding is standard on tool joints connections and central upset with 3" and 4" respectively, the types of hardbanding include ANRCO **0 XT, **0XT, **0XT.

All threads can be phosphated, copperised or cold rolled. All threads are machined with CNC Lathes-Double-shouldered and a special thread. All connections are equipped with press steel thread protectors.
