Khoom Taw Qhia

D Miningwell equis tag nrho cov pob zeb drilling cov cuab yeej nrog kev sib txhuam zoo welded laum rods. Cov threads, pas nrig lub cev thiab welded pob qij txha ntawm cov laum yeeb nkab tau ua tiav nruj heev.
Xov: Peb tuaj yeem tsim tag nrho cov xov uas ua raws li API thoob ntiaj teb cov qauv, thiab lav kev ua tiav. Cov khoom siv xov yog 35CrMo, thiab nws tau dhau los ua kev kho cua sov zoo thiab kev kho nitriding kom ntseeg tau tias qhov tawv tawv thiab kev pabcuam lub neej ntawm cov xov.
Qws lub cev: Peb tuaj yeem muab cov pas nrig nrog txoj kab uas hla ntawm 42mm-203mm, thiab qhov ntev tshaj plaws tuaj yeem ua rau 12 meters. Peb xaiv DZ40, R780, G105, S135 thiab lwm yam khoom siv pas nrig raws li qhov xav tau ntawm cov neeg siv khoom sib txawv thiab kev siv cov xwm txheej ntawm cov pas nrig, thiab cov phab ntsa tuab tuaj yeem yog 4.5mm-12mm.
Vuam sib koom ua ke: Txhua lub laum yeeb nkab tau dhau los ua cov txheej txheem pier thickening, thiab qhov siab tshaj plaws sab hauv / sab nrauv pier thickness tuaj yeem ncav cuag 24 hli, uas ua rau kom qhov sib txhuam vuam cheeb tsam thiab ua kom ruaj khov ntawm cov vuam sib txuas.
