AISI 4145H Heavy Weight Drill Pipe
AISI 4145H yog lub zog muaj zog alloy hlau feem ntau siv los ua cov yeeb nkab hnyav hnyav, tshwj xeeb tshaj yog nyob rau hauv kev lag luam roj thiab roj. Cov hlau no muaj cov khoom siv zoo thiab kev tiv thaiv corrosion, ua rau nws zoo tagnrho rau siv hauv qhov chaw ua haujlwm hnyav.
AISI 4145H tubyog ib qho hlau alloy uas tsis tshua muaj siab tawm los thiab lub zog tensile, tso cai rau nws tiv taus kev ua haujlwm siab heev. Nws kuj muaj cov hardness zoo heev, uas yuav pab txhim kho cov tho yeeb nkab hnav tsis kam thiab kav ntev.
Tsis tas li ntawd, cov hlau no muaj qhov zoo corrosion kuj nyob rau hauv ib puag ncig ua hauj lwm hnyav, ua rau nws tshwj xeeb tshaj yog haum rau cov chaw uas muaj corrosive media, xws li cov roj teb. Yuav kom ua tiav qhov yuav tsum tau muaj zog thiab cov khoom siv kho tshuab, AISI 4145H feem ntau yog quenched thiab tempered. Cov hlau no tsuas yog siv los ua cov kav dej hnyav hnyav, uas feem ntau siv rau kev sib sib zog nqus qhov drilling thiab kev tshawb nrhiav roj thiab roj hauv cov xwm txheej tshwj xeeb.

Petroleum laum dab tshos steel yog cov khoom siv zoo tshaj plaws rau kev tsim cov kav dej tho qhov hnyav. Nws siv AISI 4145H alloy structural steel li raw khoom, thiab nruj me ntsis raws li SY/T5146-1997 tus qauv thaum lub sij hawm ntau lawm txheej txheem. Weighted laum yeeb nkab muaj qhov hnyav nruab nrab, zoo ib yam li laum yeeb nkab, tab sis nws cov phab ntsa tuab yog loj dua li cov yeeb nkab laum thiab me dua li laum dab tshos. Nws lub cev tuab-walled yeeb nkab txuas nrog los ntawm ib qho tshwj xeeb txuas txuas txuas txuas, uas feem ntau yog siv los ua ib feem ntawm txoj hlua laum thiab nyob nruab nrab ntawm lub laum yeeb nkab thiab laum dab tshos los pab txhim kho kev ruaj ntseg thaum lub sij hawm drilling. Drill yeeb nkab qaug zog tuaj yeem raug txo vim qhov kev hloov pauv ntawm kab ntawv hla ntu, vim qhov no yuav pab txo qis qhov muaj peev xwm ntawm kev ntxhov siab.

siv
Thaum siv hauv cov qhov dej taw qhia, nws tuaj yeem laum ntawm kev kub ceev nrog qis torque, txo qhov hnav thiab kev puas tsuaj ntawm txoj hlua xyaum. Vim tias nws qhov rigidity me dua li ntawm cov hlua tho, nws qhov chaw sib cuag nrog cov phab ntsa zoo yog me me, thiab nws tsis yog
yooj yim ua rau lub siab sib txawv daig.
