45MnMoB Geological Drilling Pipes

45MnMoB laum yeeb nkabyog ib yam ntawm cov qauv hlau thiab hlau alloy, uas feem ntau yog siv los tsim ntau yam khoom siv xws li laum kav. Cov hlau no feem ntau yog siv los ua seamless steel kav rau pob zeb diamond core drilling. Kev kho cua sov ntawm cov hlau no feem ntau yog ua nyob rau hauv qhov kub ntawm 1194 degree txog 1656 degree.
API 5DP Geological Drill Pipe muaj lub zog siab thiab hnav tsis kam, tuaj yeem tiv taus lub siab loj thiab kev sib txhuam, thiab tsim nyog rau ntau qhov chaw drilling complex. Tsis tas li ntawd, lub laum yeeb nkab kuj muaj qhov zoo corrosion kuj thiab qaug zog, uas tuaj yeem ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem drilling.
