Drill Pipe
Drill Pipe: Ny sodina fandavahana dia ahitana ny vatan'ny sodina sy ny tonon-taolana (boaty sy pin) mitambatra, ampiasaina hampifandraisana ny fitaovana eny ambonin'ny fandavahana sy ny fitaovana ambany na ny fitaovana amin'ny lavaka ambany.Ny sodina fandavahana dia afaka mitondra fanerena mavesatra anatiny sy ivelany, ary manodina, miondrika ary mihozongozona izay azo ampiasaina mihoatra ny indray mandeha mandritra ny famokarana solika na entona.
Ny fantsona fandrefesana dia tubular vy mipetaka amin'ny tendrony misy kofehy antsoina hoe fatorana fitaovana, izay matetika ampiasaina amin'ny fihenjanana eo amin'ny tapany ambony amin'ny tady fandavahana mba hanondrahana ranon-javatra sy handefasana torsi amin'ny bit.
