Cov yam ntxwv tseem ceeb ntawm Drill Pipe

Laum yeeb nkab yog cov yeeb nkab steel nrog threaded kawg uas yog siv los txuas cov cuab yeej saum npoo ntawm lub laum rig mus rau qhov drilling thiab sib tsoo cov cuab yeej lossis cov cuab yeej hauv qab hauv qab ntawm lub laum. Lub hom phiaj ntawm cov yeeb nkab laum yog thauj cov av nkos mus rau qhov me me thiab nce, qis dua, los yog tig lub qhov hauv qab lub cuab yeej nrog lub ntsis. Lub laum yeeb nkab yuav tsum muaj peev xwm tiv taus qhov siab ntawm sab hauv thiab sab nraud, distortion, khoov thiab vibration. Nyob rau hauv cov txheej txheem ntawm cov roj thiab roj extraction thiab refining, laum yeeb nkab yuav siv tau ntau zaus.
Cov yeeb nkab huv si thiab cov yeeb nkab steel yog ua rau hauv cov yeeb nkab laum tom qab ob peb kauj ruam ua. Ua ntej tshaj plaws, los ntawm kev ua cov txheej txheem ntawm cov yeeb nkab steel thickening, qhov chaw ntawm lub teeb yeeb nkab yog nkhaus sab hauv, thiab phab ntsa ntawm cov yeeb nkab steel yog thickened. Tom ntej no, cov xov yog machined thiab plated nrog tooj liab kom muaj zog. Tom qab ntawd qhov kev ntsuam xyuas tsis muaj kev puas tsuaj yog ua tiav, ua raws li kev sib txuas ntawm cov yeeb nkab lub cev sib koom ua ke. Tom qab ntawd, cov yeeb nkab yuav raug kho cua sov thiab vuam kawg kev kho mob kom tshem tawm cov welding residual stress. Ua ntej cov yeeb nkab tiav tiav yog pleev xim rau thiab ntim, cov yeeb nkab steel tiav tau raug rau ntau qhov kev ntsuam xyuas, suav nrog kev sim hardness, ntsuas siab thiab tsis muaj kev puas tsuaj.
