Rigid hlau conduit - RMC ( hlau hlau ). RMC yog cov npe threaded hlau raceway ntawm ncig hla ntu nrog kev sib txuas, uas tuaj yeem yog tus qauv ncaj tapping kav dej coupling los yog hom integral (Duab 1). RMC yog qhov hnyav tshaj plaws-hnyav thiab tuab-phab ntsa steel kav.
Tsis tas li ntawd, dab tsi yog qhov nyuaj hlau conduit?
Rigid hlau conduit (RMC) yog tuab-walled threaded tubing, feem ntau yog ua los ntawm coated hlau , stainless hlau los yog aluminium. Galvanized rigid conduit (GRC) yog galvanized hlau tubing, nrog ib tug tubing phab ntsa uas tuab txaus kom nws yuav threaded.
Tom qab ntawd, lo lus nug yog, puas steel conduit Schedule 40? Nyuaj siv Teem caij 40 thiab ib yam li lwm cov kav dej. Rigid metallic conduit tsis muaj " teem caij "sizing.
Tsuas yog li ntawd, yuav rigid conduit xeb?
Nyuaj hluav taws xob cev is kuj muaj nyob rau hauv aluminium. Nws muaj tib qhov ntev li Sch. 40 aluminium yeeb nkab, thiab yuav yuav threaded ntawm ob kawg. Yuav yuav kim nyob qhov twg koj yuav nws, tab sis nws yuav tsis xeb.
Koj puas tuaj yeem cog rau cov kav dej hlau?
Cov raj (RMC, IMC lossis EMT) yog NEC txais hauv av txoj kev. Yog li, yog cov kab mob hauv steel kav , tsis muaj lwm tus hauv av xaim yuav tsum tau. Yog uas muab koj kev txhawj xeeb, koj tuaj yeem pom qhov txuas no qhia txog kev tshawb fawb txog kev ua haujlwm ntawm kav dej raws li a hauv av relieves lawv.

Yuav ua li cas cov nyiaj tau los thiab kev hloov pauv txawv ntawm cov khoom qub thiab cov khoom tsis zoo?
Qee cov khoom, hu ua cov khoom qis, feem ntau txo qis hauv kev siv thaum twg cov nyiaj tau los nce. Kev siv nyiaj thiab kev siv cov khoom ib txwm muaj feem ntau nce nrog lub zog yuav khoom ntau dua, uas yog qhov sib piv nrog cov khoom qis dua
Dab tsi yog qhov tsis zoo ntawm kev siv cov khoom siv hluav taws xob txuas ntxiv dua tshiab?
Ib qho ntawm qhov tsis zoo ntawm lub zog tsis txuas ntxiv yog tias nws siv sijhawm ntev. Mining ntawm cov thee, nrhiav cov roj, txhim kho cov roj xyaum, tsim cov roj rigs, ntxig cov kav dej kom tshem tawm thiab kev thauj mus los ntawm cov roj av yog cov txheej txheem siv sijhawm ntau. Lawv kuj siv zog ntau heev
Dab tsi yog qhov zoo ntawm kev siv cov khoom siv hluav taws xob txuas ntxiv lossis tsis muaj zog?
Cov txiaj ntsig ntawm RENEWABLE ENERGY SOURCES (RES) Lawv yog cov khoom siv hluav taws xob uas tsis muaj zog (hnub, cua, dej ntws, organic teeb meem, thiab lwm yam) thiab pab txo qis kev cia siab ntawm cov khoom siv hluav taws xob tsis zoo, xws li roj, nkev, roj, thiab lwm yam
Koj tuaj yeem qhia tau li cas yog tias cov hlau yog ferrous lossis tsis yog ferrous?
Cov lus teb yooj yim yog cov hlau ferrous muaj hlau, thiab cov hlau tsis muaj hlau tsis muaj. Qhov ntawd txhais tau tias txhua hom ferrous thiab non-ferrous hlau muaj qhov sib txawv thiab siv. Ferrous hlau muaj hlau, thiab paub txog lawv lub zog. Xav tias steel, stainless hlau, carbon steel, cam khwb cia hlau
Puas yog cov nyiaj tau los uas tsis tau them nqi yog cov khoom vaj khoom tsev cog lus?
Cov koom haum tsis tas yuav tsum siv cov ntsiab lus "cov khoom vaj khoom tsev cog lus" thiab "kev cog lus lav" (606-10-45-5). Piv txwv li, cov cuab yeej cog lus yuav raug hu ua cov nyiaj tsis tau txais los yog cov nyiaj them ua ntej yuav raug them. Daim ntawv cog lus kev lav phib xaub yuav raug piav qhia raws li cov nyiaj tau los ncua, cov nyiaj tau los tsis tau txais, lossis kev lav nyiaj rov qab
