Kev tsim cov dej laum pas nrig feem ntau suav nrog kev siv cov khoom siv hlau zoo lossis cov khoom siv hlau uas tuaj yeem tiv taus qhov xav tau qhov drilling. Nov yog qee cov khoom siv feem ntau siv rau kev tsim cov dej laum pas nrig:
Hlau: Hlau yog cov khoom siv tseem ceeb rau cov pas dej da dej. Nws muab lub zog, durability, thiab tsis kam rau cov kev ntxhov siab thiab lub zog uas tau ntsib thaum lub sijhawm ua haujlwm drilling. High-qib steel alloys, xws li carbon steel los yog hlau alloy, feem ntau yog siv los xyuas kom meej qhov tsim nyog txhua yam khoom thiab toughness ntawm laum rods.
Alloying Elements: Ntau yam alloying ntsiab yuav raug ntxiv rau cov hlau muaj pes tsawg leeg los txhim kho cov khoom tshwj xeeb ntawm cov pas dej laum. Piv txwv li, chromium, npib tsib xee, los yog molybdenum tuaj yeem txhim kho corrosion thiab lub zog. Alloying ntsiab feem ntau ntxiv nyob rau hauv meej proportions kom ua tiav cov yam ntxwv ntawm cov khoom xav tau.
Cov ntaub ntawv kho cua sov: Kev kho cua sov yog ib qho tseem ceeb hauv kev tsim cov dej laum rods kom zoo dua lawv cov khoom siv kho tshuab. Cov ntaub ntawv kho cua sov, xws li quenching thiab tempering agents, yog siv los ua kom tiav qhov xav tau hardness, toughness, thiab tensile lub zog ntawm lub laum pas nrig.
Thread Coatings: Cov xov txheej yog qee zaum siv rau lub laum pas nrig xov los txhim kho lawv cov hnav tsis kam thiab txo kev sib txhuam thaum sib dhos thiab disassembly. Cov xov txheej uas muaj xws li zinc lossis tooj liab-raws li txheej, uas txhim kho xov lub neej thiab tiv thaiv galling lossis seizing.
Qhov tseem ceeb ntawm cov khoom siv raw hauv kev tsim cov drill rods tuaj yeem ua tiav raws li hauv qab no:
Lub zog thiab Durability: Dej laum pas nrig yuav tsum tiv taus lub zog siab thiab hnyav thaum lub sijhawm ua haujlwm drilling. Yog li ntawd, xaiv cov khoom zoo raw khoom yog qhov tseem ceeb heev. Cov khoom siv hlau tsim nyog los yog alloy muab qhov tsim nyog lub zog thiab ua haujlwm kom tiv taus kev vibrations, cuam tshuam, thiab siv tas li.
Corrosion Resistance: Dej drilling feem ntau tshwm sim hauv qhov chaw ntub dej, ntub dej, lossis corrosive ib puag ncig. Kev tiv thaiv corrosion ntawm cov ntaub ntawv raw yog qhov tseem ceeb rau lub neej ntev thiab kev ua haujlwm ntawm cov laum pas nrig. Kev xaiv cov khoom tsim nyog thiab cov txheej txheem corrosion-resistant tuaj yeem tiv thaiv corrosion, xeb, thiab kev puas tsuaj rau cov pas nrig.
Machinability: Lub machinability ntawm raw cov ntaub ntawv cuam tshuam rau efficiency thiab zoo ntawm cov txheej txheem ntau lawm. Cov ntaub ntawv tsim nyog yuav tsum muaj kev ua haujlwm zoo, tso cai rau cov hlua tho kom yooj yim txiav, zoo li, thiab ua tiav.
Kev kho cua sov yam ntxwv: Kev kho cua sov yog ib kauj ruam tseem ceeb hauv kev tsim cov laum rods. Los ntawm kev tswj cov txheej txheem cua sov thiab cua txias, qhov hardness, toughness, thiab lub zog ntawm cov laum pas nrig tuaj yeem txhim kho. Xaiv cov ntaub ntawv tsim nyog rau kev kho cua sov kom ntseeg tau tias cov laum rods muaj qhov xav tau lub cev thiab kev ua haujlwm.

Dej Drill Rods feem ntau yog siv rau hauv mining, quarrying, thiab kev tsim kho kev lag luam rau percussive drilling hauj lwm. Cov laum rods no yog tsim los xa cov tshuab muaj zog rau lub laum me ntsis, tso cai rau kev nkag mus tau zoo ntawm cov pob zeb nyuaj. Nov yog qee qhov ntau thiab tsawg thiab xov hom rau DTH laum rods:
Qhov ntau thiab tsawg:
3.5 nti (89 mm): Qhov no yog tus qauv loj rau me me Drill Rods siv nyob rau hauv daim ntaub ntawv xws li geotechnical drilling thiab me me mining ua hauj lwm.
4 nti (102 hli): Qhov loj me no feem ntau siv rau nruab nrab DTH laum rods hauv ntau daim ntawv thov drilling.
5 nti (127 mm): Qhov loj dua no feem ntau yog siv rau qhov hnyav-dej Drill Rod rau qhov drilling hauv cov pob zeb nyuaj thiab cov pob zeb loj dua lossis kev tsim kho.
Hom xov:
API REG: API (American Petroleum Institute) REG (Regular) xov yog ib hom xov siv dav rau DTH laum rods. Nws nta cov xov kab sib txuas thiab sib xws nrog ntau yam DTH hammers thiab laum khoom.
API IF (Internal Flush): API Internal Flush xov yog lwm hom xov uas siv rau DTH laum rods. Nws tso cai rau kev ntws tawm sab hauv ntawm txoj hlua laum, ua kom yooj yim tshem tawm cov laum txiav thaum lub sijhawm ua haujlwm drilling.
