Product Description API 7-1 HWDP Heavy Weight Drill Pipe for drillingIntegral heavy weight drill pipe is manufactured from AISI 4142H-4145H modified drill collar material according to SY/T5146-1997,thick-walled pipe called integral heavy weight drill pipe was developed to provided a gradual transition from the heavydrill collars to the relatively light weight drill pipe. This intermediate weight pipe has a wall thickness of approximately, andhelps prevent stress concentration at the top of the drill collars. It also allows you to drill at higher rpms, reducing torqueand differential pressure sticking. It is intended primarily for directional drilling. Because it bends easily, it simplifiesdirectional control and minimizes connection fatigue problems common to high angle or horizontal drilling. The reduced number ofpipe failures and increased drill stem service also make it appropriate for some straight-hole applications.Welcome to consult, we will provide the most comprehensive technical support!Product NameAPI 5DP standard HWDP/AISI 4145H Integral Heavy Weight Drill Pipe in oil and gas well drilling with hardfacing and coatingStandardAPI 5DPGradeDrill Pipe BodySL.1: E, X, G, S / SL.2: G, STool JointSL.1, SL.2, SL.3Minimum Order Quantity10 TonOutside Diameter Ranges23/8 inch to 65/8 inchWall Thickness6.45mm to 12.70mmLengthR1: 6.10-7.01m / R2: 8.84-9.75m / R3: 12.19-13.72TypeSeamless / WeldedUpset StyleIU, EU, IEURotary Shouldered Connection StyleNC40, NC46, NC26, NC31, NC38, NC50, 51/-2FH, 65/8FHIntegral heavy weight drill pipe is manufactured from AISI 4142H-4145H modified drill collar material according to SY/T5146-1997,thick-walled pipe called integral heavy weight drill pipe was developed to provided a gradual transition from the heavydrill collars to the relatively light weight drill pipe.
