Features and advantages of heavy drill pipe
1. Extra length of tool joints provides plenty of space to operate while reducingwear rate and extending the service life of the outer diameter.
2. In order to extend the service life of the connection, API Bore Back Box adopts the larger size, whose function is four times as large as the other entire box.
3. The entire centre upset protects the tube from outer diamete wear by keeping the tube away from the hole wall, while at the same time reducing the risk of differential sticking.
4. HWDP with the drill pipe elevator can quickly and effectively deal with the task of drilling platform.
5. Research shows that 95% of the cause for drill string failure can be attributed to fatigue failure. However, the structure of HWDP has high fatigue strength.
