Lub laum yeeb nkab, daim ntawv luv luv ntawm lub qhov laum yeeb nkab, yog ib hom kev sib tw sab nraud.Nws yog tsuas yog siv nyob rau hauv teb percussive drilling uas muaj gases thiab kua.Nws cov khoom tseem ceeb suav nrog cov yeeb nkab (qhib) lub cev thiab sib koom ua ke.

Peb lub qhov dej laum yeeb nkab yog tsim los ntawm API cov qauv.Thiab raws li cov kev cai tshwj xeeb, peb kuj muab cov yeeb nkab zoo li no hauv cov lus suav thiab Asmeskas sib txawv.

Raws li rau nws qhov zoo, nws muaj cov yam ntxwv ntawm qhov loj rigidity, zoo sealing muaj peev xwm, tiaj tus txheej txheem, thiab tsis tshua muaj torque thiab kuj thaum rotating.

Raws li kev ntim khoom, ib pob ntawm cov yeeb nkab laum yuav tau ntim los ntawm ib txheej ntawm steel ncej, thiab ib pob yuav muaj 9 mus rau 40 lub laum kav.

Raw Khoom: Kub dov seamless yeeb nkab, los ntawm BAO STEEL / TPCO / BAO GANG thiab lwm yam, nruj me ntsis raws li cov qauv kev soj ntsuam, los ntawm cov khoom tsim, kev cog ob qho kev tshuaj xyuas, kom ntseeg tau tias cov khoom siv raw khoom zoo.
