Heavy Weight Drill Pipe (HWDP) for oilfield API standard complied
1.Size: 2 7/8", 3 1/2", 4 1/2", 5", 5 1/2"
2.Products description
Our integral HWDP is made from one piece of AISI 4145H solid bar, fully heat treated, all physical properties conform to API Spec 7 latest edition.
The 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 co***red 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.Helpful for keep 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.
Standard Bands:
One 4" wear band on both pin and box end, plus one 1" band on 18ˇăshoulder of box.
Two 3" wear bands on central upsets
The hardbanding is completely flush on both tool joints and 1/8" oversize on the central upset (fully flush on request).
The types of Hardbanding include Iron-Matrix powder alloy, Tungsten Carbide particle, and Arnco 100XT.
HWDP could be coated internally with DPC (equivalent to TK 34) as customer's request that are able to prevent corrosion and extend using time.
