Laum lub cev yog siv rau cov tub ntxhais drilling rau geological department, uas yog ib hom ntawm hollow cross seem, tsis muaj seams nyob ib ncig ntawm lub bar ntev ntawm steel.Steel hollow seem nrog cov yeeb nkab loj rau kev thauj cov kua dej, xws li kev thauj mus los ntawm cov roj, roj, roj, roj, dej thiab qee cov khoom siv, cov kav dej, thiab lwm yam.. Siv tau muab faib ua cov yeeb nkab laum, laum dab tshos, cores, tes tsho thiab lwm yam. cov dej nag.

Drill yeeb nkab: cov pov thawj underground pob zeb qauv, dej hauv av, roj, natural gas thiab minerals, siv cov rigs drilling qhov dej.Roj, roj kev tshawb fawb yog tsis muaj qhov dej, geological drilling seamless steel yeeb nkab khoom, nrog rau cov tub ntxhais tube, tub ntxhais yeeb nkab, casing, laum yeeb nkab.Drilling yeeb nkab mus tob rau hauv qhov tob ntawm ob peb kilometers strata, kev ua hauj lwm tej yam kev mob yog heev complex, laum yeeb nkab los tiv thaiv lub rub, siab, dabtsi yog khoov, twisting thiab tsis sib xws tej yam kev mob load kev nyuaj siab, tab sis kuj los ntawm cov av nkos, pob zeb hnav, yog li ntawd, yuav tsum tau cov yeeb nkab yuav tsum. muaj zog txaus, hardness, hnav tsis kam thiab toughness.

Drill Pipe los yog qia uas tau siv feem ntau yog xa mus rau lub vaj rau kev tshuaj xyuas thiab raug txheeb xyuas thiab khaws cia kom txog thaum qhov chaw tshiab rau qhov drilling tuaj yeem tshawb xyuas.Cov kav dej Drill yog siv nyob rau hauv qhov chaw tshuaj xyuas nrog rau ntau lub tswv yim ntawm lwm cov khoom siv xws li lub ntsuas phoo.Cov yeeb nkab nrhiav qhov tsis muaj zog nyob rau hauv metallurgical muaj pes tsawg leeg los tiv thaiv cov qia drilling los ntawm kev puas tsuaj rau yav tom ntej zoo tho txawv.Cov yeeb nkab rau drilling ntawm cov roj rig yog ib kem, hlua lossis cov kav dej uas siv rau kev sib kis ntawm cov dej drilling nrog kev pab los ntawm cov av nkos.

Geological Drilling Yeeb Nkab
Geological raj yog steel yeeb nkab uas siv cov tub ntxhais drilling rau lub geological department, uas ib tug hollow cross seem, surrounded los ntawm ntev geological drilling pob qij txha nrog steel kav.

Geological yeeb nkab (YB235-70) nrog lub hollow cross seem, cov kav dej ntau, rau kev xa cov kua dej xws li kev thauj mus los ntawm cov roj, roj, roj, dej thiab qee cov khoom siv, cov kav dej, thiab lwm yam. Los ntawm kev siv kawg tuaj yeem muab faib. nyob rau hauv lub laum yeeb nkab, laum dab tshos, lub core yeeb nkab, casing thiab nag los nag.

Txhawm rau tshawb xyuas cov pob zeb hauv av hauv kev siv cov raj geological, geological drilling yeeb nkab, dej hauv av, roj, roj thiab cov khoom siv ntxhia, siv cov rigs drilling qhov dej.Roj, roj, mining tsis tuaj yeem raug cais tawm ntawm qhov dej drilling, geological drilling thiab roj drillingseamless steel yeeb nkab, cov khoom siv drilling, nrog rau cov tub ntxhais sab nrauv, tub ntxhais tube,casing, laum cev.Drilling raj sib sib zog nqus mus rau hauv qhov tob ntawm ob peb kilometers strata, kev ua hauj lwm tej yam kev mob yog heev complex, laum yeeb nkab kom tiv taus nro thiab compression, dabtsi yog khoov, torsion, thiab lub unevenly cuam tshuam load kev nyuaj siab, tab sis kuj los ntawm cov av nkos, pob zeb hnav, yog li ntawd, cov yeeb nkab yuav tsum muaj lub zog txaus, hardness, hnav tsis kam thiab cuam tshuam toughness.
