API SPEC 7-1 Drill Pipe Tuam Tshoj Hoobkas
Drill Pipe yog ib qho hnyav, seamless raj tuaj yeem tig lub laum me ntsis thiab circulates drilling kua. Nws tso cai rau cov dej drilling yuav tsum tau pumped los ntawm me ntsis thiab rov qab mus rau lub annulus. Cov yeeb nkab yog raug rau axial nro, tsis tshua muaj siab torque thiab siab sab hauv. Drill Pipe yog cov kav hlau ruaj ruaj siv hauv kev ua haujlwm drilling, cov qauv hauv API 5DP thiab API SPEC 7-1.

API 5DP laum yeeb nkab yog trailing nrog cov ntsia hlau xov rau txuas cov drilling rig nyob rau hauv qab ntawm cov khoom siv drilling thiab cov khoom siv zeb lossis cov khoom siv hauv qab. Lub hom phiaj yog los laum cov av nkos xa mus rau lub laum me ntsis, thiab xyaum nrog qhov nce, txo qis lossis tig qhov hluav taws xob hauv qab txhais tau tias. Drilling yeeb nkab yuav tsum muaj peev xwm tiv taus sab nraud siab, sib tw, khoov thiab vibration. Nyob rau hauv cov mining thiab roj thiab roj refining txheej txheem, lub laum yeeb nkab yuav siv tau ntau zaus.
① Yuav ua li cas txog koj lub tuam txhab?
Ib qho ntawm cov tuam txhab ua lag luam thiab cov neeg muag khoom tshwj xeeb hauv cov khoom siv laum yeeb nkab hauv Suav teb, feem ntau muab cov kav dej laum nrog rau cov roj laum yeeb nkab, cov dej zoo laum yeeb nkab, cov yeeb nkab laum tiaj tus, geological laum yeeb nkab thiab cov yeeb nkab tsis yog khawb. Lwm yam tshaj li cov kav dej laum peb kuj muaj peev xwm muab tau ntau yam khoom siv hauv cov kav dej, cov tho pob qij txha, steel yeeb nkab fittings, li qub thiab lwm yam muaj peb qhov kev muag khoom ib leeg. Kev muag khoom thiab kev pabcuam ua ke ua kom cov neeg siv khoom nrog ntau yam kev xav tau yooj yim dua rau kev tswj xyuas kev yuav khoom.
② Yuav ua li cas lav qhov zoo ntawm cov khoom?
Peb tau tsim lub thoob ntiaj teb kev tswj hwm kev ua tau zoo, txhua qhov txuas los ntawm cov khoom siv raw mus rau cov khoom kawg peb muaj kev xeem nruj heev; Peb tau txiav txim siab muab qhov kawg rau cov khoom tsis tsim nyog ntws mus rau hauv kev ua lag luam. Nyob rau tib lub sijhawm, peb yuav muab cov kev pab cuam tom qab tsim nyog.
③ Ntev npaum li cas peb tuaj yeem tau txais cov khoom tom qab kev yuav khoom?
Hauv kev yuav khoom hauv 7 hnub ua haujlwm, Peb yuav npaj lub Hoobkas xa khoom sai li sai tau.
