Lub ntsiab lus ntawm Schedule 40 yeeb nkab yog dab tsi?
Nyob rau hauv lub realm ntawm industrial piping, "schedule" hais txog lub thickness ntawm ib tug yeeb nkab phab ntsa. Tus nqi tus lej hauv "Schedule 40" tshwj xeeb yog sawv cev rau qhov ntsuas siab ntawm cov yeeb nkab. Hauv qhov no, cov yeeb nkab yog tsim los tiv thaiv lub siab ntawm 40 phaus ib square inch (PSI). Yog li ntawd, Teem caij 40S kav dej tau zoo- haum rau cov ntawv thov uas muaj kev kub ntxhov nyob nruab nrab.
Tshwj xeeb, Teem sijhawm 40 steel yeeb nkab yog ib qho kev xaiv siv los qhia txog qee yam qauv tuab rau cov kav dej. Hauv cov ntsiab lus ntawm cov kav dej steel, Teem sijhawm 40S qhia txog qhov nruab nrab tuab, thiab nws yog ib qho ntawm cov sijhawm siv ntau tshaj plaws siv rau ntau yam kev siv. Qhov no tuaj yeem ua tau zoo tshwj xeeb hauv cov xwm txheej uas yuav tsum muaj qhov ruaj khov thiab raug nqi - yuav tsum tau siv cov kav dej zoo, xws li hauv cov kav dej, kav dej, lossis cov phiaj xwm dav dav.
Raws li NPS thiab lub sijhawm ntawm cov yeeb nkab, cov yeeb nkab sab nraud txoj kab uas hla (OD) thiab phab ntsa tuab tuaj yeem tau txais los ntawm cov lus siv xws li cov hauv qab no, uas yog ua rawsASME B36.10Mthiab B36.19M.

Cov lus nug nquag nug (FAQ)
1. Puas yog Schedule 40 yeeb nkab galvanized?
Teem sijhawm 40 hais txog cov tuab, tsis yog txheej txheej. Txawm li cas los xij, SCH 40 cov kav dej tuaj yeem ua taugalvanized(zinc{0}}coated) los tiv thaiv xeb los yog sab laug li "dub steel" rau kev siv roj thiab roj.
2. Teem sijhawm 40 steel yeeb nkab tuaj yeem welded?
Yog lawm. Cov pa roj carbon steel SCH 40 yeeb nkab yog cov khoom siv tau zoo heev uas siv cov txheej txheem zoo li TIG, MIG, lossis cov hlua txuas, ua rau nws zoo tagnrho rau cov qauv tsim.
3. SCH 40 thiab SCH 80 yog dab tsi?
Qhov sib txawv tseem ceeb yog qhovphab ntsa thickness. Teem sijhawm 80 muaj phab ntsa tuab, tso cai rau nws los tswj cov kev ntxhov siab hauv siab dua li Teem sijhawm 40.
