Cov kav dej laum tau siv dav hauv mining, geological tshawb nrhiav thiab txhua yam kev drilling (dej, roj, roj, thiab lwm yam) cov dej num.As ib tug ua laum yeeb nkab tsim, peb ua txhua yam ntawm cov qauv thiab tsis-tus qauv laum kav rau peb cov neeg muas zaub.Peb cov kav dej muaj xws li steel laum yeeb nkab, mining laum yeeb nkab, dej zoo laum yeeb nkab, roj zoo laum yeeb nkab, API laum yeeb nkab, DTH laum pas nrig, xov hlau laum pas nrig, thiab lwm yam.

Cov yam ntxwv tseem ceeb ntawm lub siab zoo DTH raj yog durability, raug thiab tswj tau.

 Drill Pipe :

1. Tube lub cev: txias kos seamless yeeb nkab.yog li cov yeeb nkab muaj qhov loj me, zoo centralizer.
2.Pipe lub cev cov khoom yog tib qib raws li Sandvik.
3.Thread connector: Kev kho cua sov thiab Nitrogen, yog li cov yeeb nkab muaj zog dua thiab yooj yim rau kev thauj khoom thiab tshem tawm.
4. Kev sib txhuam vuam.

Standard DTH laum yeeb nkab:

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

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