Heavy Weight Drill Pipe (HWDP)

Heavy weight drill pipe (HWDP) is a type of drill pipe that is thicker and has longer upsets than conventional drill pipe. This makes it stronger and more resistant to fatigue, making it ideal for use in directional drilling and other applications where high torque and differential pressure are present.

Specifications

HWDP is available in a variety of materials, sizes, and lengths to meet the specific needs of each application. Typical specifications include:

• Material: E75/X95/G105/S135

• OD: 2 3/8″ to 6 5/8″

• Wall thickness: 6.45mm to 12.7mm

• Length: R1(6.10-7.01meters) R2(8.84-9.75meters) R3(12.19-13.72meters)

• Hard band: Arnco100XT, Arnco200XT and Arnco300XT; Botn1000, Botn3000, TCS8000, TCS-Titanium, Armacor M etc. Also we can make according to customers’ requirements.

• Standard: API 5DP

• RSC Type: NC26 NC31 NC38 NC40 NC46 NC50 NC55 6-5/8FH

• UPSET: EU(External upset) IU(Internal upset) IEU(Internal & External upset)

• Technical: Hot Rolled

Benefits

The benefits of using HWDP include:

• Increased strength and resistance to fatigue

Additional Information

HWDP is manufactured using a process that involves preheating, water quenching, and tempering. This process results in a unique combination of hardness, yield strength, and impact strength that makes HWDP more resistant to stress corrosion cracking and hydrogen embrittlement in a hydrogen sulfide environment.

HWDP is also available in a variety of hard bands to meet the specific needs of each application. The hard band is a layer of material that is applied to the outside of the drill pipe to improve wear resistance. The most common hard bands are Arnco100XT, Arnco200XT, and Arnco300XT.

HWDP is a versatile and reliable product that is ideal for use in a variety of demanding applications. If you are looking for a drill pipe that is strong, durable, and resistant to fatigue, then HWDP is the perfect solution for you.
