Qhov ntau thiab tsawg ntawm cov yeeb nkab tsis yog arbitrary thiab yuav tsum tau ua raws li qhov tshwj xeeb sizing system.Qhov ntev ntawm cov yeeb nkab steel yog nyob rau hauv millimeters, tab sis qee lub tebchaws siv ntiv tes (inch hauv lus Askiv, lossis zoll hauv German).Yog li ntawd, muaj ob hom steel kav - TUBE thiab PIPE.TUBE yog siv nyob rau hauv lub tshuab hluav taws xob lossis lub zog kev lag luam los piav txog sab nraud txoj kab uas hla hauv ntiv tes.PIPE yog siv los ua cov kav dej rau cov xov xwm sib txawv.PIPE loj yog siv los ua qhov nominal loj ntawm cov yeeb nkab steel.Ib tug 12-nti steel yeeb nkab kuj tuaj yeem pom qhov kwv yees tus nqi ntawm lub puab kab.PIPE loj hloov mus rau mm yog txoj kab uas nyiam rau sab nraud ntawm cov yeeb nkab steel (thawj kab siv EN10220, DIN2448, thiab lwm yam).Qhov ntawd tsis yog hais tias peb tsis siv kab thib ob thiab thib peb.Qhov thib ob thiab thib peb-kab qhov ntev yog TUBE cov qauv rau kev tsim hluav taws xob thiab cov kav hlau siv tshuab.
Steel yeeb nkab tuab phab ntsa series
Cov phab ntsa tuab ntawm cov yeeb nkab steel yog los ntawm British Units of Measurement, thiab qhov ntev yog qhiaby kev ua txhaum cai.PIPE phab ntsa thickness los ntawm Schedule series (40, 60, 80, 120), thiab txuas nrog hnyav series (STD, XS, XXS).Cov lej noqhov tseem ceeb yog hloov mus rau millimeters raws li ib feem ntawm cov yeeb nkab phab ntsa thickness series.(Ceeb Toom: Qhov Loj-Schedule40 tus nqi tsis tas li, tab sis nyob ntawm txoj kab nruab nrab ntawm lub raj. BWG thiab SWG nplai yog siv rau phab ntsa thickness tus nqi ntawm TUBE hom. Tom qab hloov mus rau millimeters, cov txiaj ntsig no dhau los ua ib feem ntawm phab ntsa tuab Cov yeeb nkab steel sab nraud thiab phab ntsa thickness qhov ntev ntawm precision steel kav siv nyob rau hauv cov teb chaws Europe thiab lub teb chaws uas siv lub International System ntawm units yog sib npaug zos rau approximations.
