China API 7-1/API 5dp 5 Inch Heavy Weight Drill Pipes

Heavy Weight Drill Pipe (HWDP) was developed to provide a gradual transition from the drill collars to the drill pipe. This HWDP helps to prevent stress concentration at the top of the drill collar.It also allow drilling at higher rpms, reducing torque and differential pressure sticking. The HWDP is intended primarily for directional drilling.

DRILL PIPE DP-Master Drill Pipe Manufacturer

FEATURES AND OPTION. DESIGN. DP-Master incorporates generous internal upset length (miu) and radii to achieve a longer and smoother transition back onto the pipe body ID. This lowers the stress in this very critical section of drill pipe and ensures maximum improvement to the fatigue life of the drill pipe. Drill Pipe Heavy Weight Chart Download Drill Pipe Heavy Drill pipe heavy weight is a type of drill pipe with thickened walls and longer collars compared to the standard drill pipe. This provides the heavy weight drill pipe (HWDP) with higher tensile strength. To facilitate greater support, HDWP is positioned near the topmost part of a long drill string. Drill Pipe Heavy Weight Specifications Drill Pipe and Heave Weight Drill Pipe Specifications 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. The tube is connected with special length-added drill pipe joint (integral heavy weight drill pipe is made up of tube and tool joint).

Heavy Weight Drill Pipe (HWD) - Div Drilling

Heavy Weight Drill Pipe (HWDP) Our Heavy Weight Drill Pipe (HWDP) offers a gradual transition from heavy, rigid drill collars to the more flexible drill pipe which helps to reduce the number of fatigue failures seen directly above the Bottom Hole Assembly (BHA). We offer heavy weight in 3.1/2, 4, 5 and 5.1/2 consisting of Heavy Weight Drill Pipe Specs & Selection - Drilling ManualNov 04, 2017 · In order to reduce the stiffness ratio and increase service life of the drill pipe, heavy weight drill pipe having the same OD as the drill pipe and a wall thickness of up to 1 in and weight up to 78 lb/ft is used between the drill pipe and the drill collars.

Heavy Weight Drill Pipe - NOV Inc.

Heavy weight drill pipe also enables drilling at higher RPMs, reducing torque and differential pressure sticking. Heavy weight drill pipe is well-suited for directional drilling applications. Because it bends easily, heavy weight drill pipe simplifies directional control and minimizes connection fatigue problems that are common in high-angle or horizontal drilling.
