Aliminyòm alyaj sèvi ak machin tiyo kò moun k'ap fè alyaj aliminyòm. Paske ti pwa, aliminyòm alyaj sèvi ak machin fif bezwen anba pouvwa à, rapid vitès ki fè tiyo kwochèt ak plis kapasite forage de forage. Avantaj li nan pwopwiyete mekanik se tenasite anwo nan syèl la, fleksibilite bon nèt ak ti frottement ak miray la lè à. Aliminyòm sèvi ak machin tiyo kò a ak jwenti tou de jwi pèsistans ak ba depans pou antretyen. Li bezwen forage pouvwa an ak forage pompes pouvwa paske rezistans inondasyon an espas annulaire ti jan sa dwe fèt.

The aluminum alloy drill pipe body is made of aluminum alloy. Because of light weight, the aluminum alloy drill pipe needs lower upgrading power, quicker speed of pipe tripping and more drilling ability of rigs. Its advantage in mechanical properties is high tenacity, perfect flexibility, and small friction with the wall when upgrading. The aluminum drill pipe body and joints both enjoy longevity and low expenses for maintenance. It needs lower drilling power and drilling pumps power because the flow resistance of annular space is quite small.
