Drill pipe ni chitoliro cha chisulo icho chili na ulusi ku umaliro uwo ukukoleska vipangizo vya pa charu chapasi vya drilling rig na vipangizo vyakuboora na kugaya panji bottom-hole assembly pasi pa chisimi. Drill pipe yikunyamura matope ghakuboolera ku drill bit ndipo, pamoza na drill bit, yikukwezga, kukhizga, panji kuzungulira msonkhano wa pasi-hole. Chitoliro cha drill chikwenera kuzizipizga kufinyikizgika kwa mukati na kuwaro, kupotoloka, kupindika, na kugwedezeka. Chitoliro cha Drill chingagwiriskikiya nchitu kanandi waka pa nyengu yo mafuta ndi gasi lafumiskika ndipuso kutozga.
Chitoliro cha Drill chikupangika kufuma ku chitoliro chambura kanthu na chitoliro cha chisulo chambura kupangika kwizira mu masitepe ghanandi ghakunozga. Chakwamba, chigaŵa cha kuwaro cha chitoliro chambura kanthu chikupindika mukati, ndipo chikupangiska kuti khoma la chitoliro liŵe lakukhora. Kufuma apo, ŵakuwuŵikapo ulusi na kuwuphakazga na mkuŵa kuti uŵe wakukhora. Non-kunanga mtundu wa kuwoneseska kukuchitika ntheura, ndipo pamanyuma pake ŵakuwotcha viŵaro vya thupi la chitoliro. Pamanyuma pake thupi la chitoliro likuchizgika na kutentha kwa weld ndiposo likuchizgika na weld yaumaliro kuti lileke kusuzgika na weld wakukhalira. Kuyezgeka kwakusazgikira, kusazgapo kuyezga kukhora, kuyezga kupanikizika, na kuyezga kwambura -kunanga, kukuchitika pa chitoliro cha drill chakumalira pambere chindapenteke na kuŵikika mu mathumba.
