Amapayipi okubhoboza i-DTH adlala indima ebalulekile kukho konke ukubhola kwe-DTH, kungakhathaliseki ukuthi hlobo luni lwetshe, ukujula kwembobo noma umshini wokubhoboza.

Izici ezibalulekile zeshubhu ye-DTH yekhwalithi ephezulu ukuqina, ukunemba nokuphathwa.

 Drill Pipe :

1.Umzimba wepayipi: ipayipi elibandayo elidonsayo elingenamthungo.ngakho-ke ipayipi inosayizi onembile, i-centralizer enhle.
2.Impahla yomzimba wepayipi iyibanga elifanayo nele-Sandvik.
3.Isixhumi sochungechunge :Ukwelashwa kokushisa neNitrojeni , ngakho ipayipi lihlala isikhathi eside futhi kulula ukulilayisha nokulikhipha .
4.Friction welding.

Ipayipi lokubhoboza elijwayelekile le-DTH:

Ububanzi: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm;

Ubude: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;
