Drill Pipe
Drill Pipe: Boarpijp omfettet piiplichem en arkgewrichten (doaze en pin) oaninoar laske, brûkt foar it ferbinen fan boarrings-oerflakapparatuer en boaiemapparatuer as apparatuer foar boaiemgat.Drill pipe kin drage swiere ynterne en eksterne druk, en twist, bocht en trilling dy't kin brûkt wurde mear as ien kear tidens oalje of gas produksje.
Boarpijpen binne stielen buizen foarsjoen fan threaded úteinen neamd ark gewrichten, dy't ornaris wurde brûkt yn spanning yn it boppeste diel fan 'e drill string te pompen floeistof en oerdrage koppel nei it bit.
