ASTM A53 Welded Yeeb Nkab rau cov ntawv thov tshwj xeeb
Roj thiab roj Kev Lag Luam:
Siv hauv cov raj roj qis kom thauj cov roj, nkev thiab lwm yam hydrocarbons rau kev sau cov kab, pub thiab fais fab faib cov tshuab.
01
Kev tsim kho thiab vaj tse ib puag ncig:
Siv rau hauv cov ntawv thov cov txheej txheem xws li kab ntawv, kab teeb thiab txhawb nqa, nws feem ntau siv hauv scaffolding, cov txheej txheem ib ntus thiab muaj lub zog siab thiab tus nqi ua tau zoo.
02
Kev siv dej thiab cov thawv ntim khoom:
Feem ntau siv los thauj dej, dej phwj thiab lwm yam kua, rauv welded kav (hom F) tuaj yeem siv rau hauv tsis yog-tseem ceeb tshaj qhov siab piping tshuab.
03
Kev Siv Khoom Siv Tshuab:
Raws li cov txheej txheem yeeb nkab txheej txheem lossis cov txheej txheem sib xyaw ua ke hauv cov cuab yeej siv tshuab, qib qib b yog feem ntau xaiv rau lub zog siab dua thiab kev ntseeg tau nyob hauv kev muaj kev lag luam hnyav.
04
Chav thiab Tshav Kub Hloov Chaw:
Rau cov kab hluav taws xob tsawg dua thiab cov pa hluav taws kub vim lawv cov cua sov tsis kam, seamless kav dej yog nyiam dua rau qhov kub thiab txias.
05
ASTM A53 Welded Yeeb Yam ntxwv
Cov Khoom Zoo Cov Khoom Siv:
Lub zog tensile lub zog thiab tawm lub zog muaj zog, nce qib tensile lub zog ntau dua los yog sib npaug rau 330mpa, tawm los ntawm 205mpa; Qib Bensile lub zog loj dua los yog sib luag rau 415MPA, tawm los ntawm lub zog ntau dua lossis muaj sib npaug rau 240MPA. Nyob rau tib lub sijhawm, nws txoj kev ua kom zoo yog qhov zoo, elongation ntawm qib a thiab b weldability thiab formability yog siab 20%, uas tuaj yeem ua tau zoo ntawm 20%
Siab weldability thiab formability:
Nws yog qhov haum rau kev siv vuam ua haujlwm, tab sis kuj haum rau winding, khoov, flanging, flanging thiab lwm yam kev ua haujlwm. Qhov no muab nws qib siab ntawm kev hloov pauv thaum tsim khoom thiab kev teeb tsa, tso cai rau kev ua kom yooj yim ntawm chaw thiab sib dhos.
Corrosion Kuj:
Los ntawm kev saib xyuas kom tsim nyog thiab cov txheej, xws li kub dip galvanizing, xeb thiab oxidation tuaj yeem tiv thaiv nws lub neej ua haujlwm hauv ntau qhov chaw ib puag ncig.
Tus nqi pib tsim nyog:
Piv rau alloy steel lossis lwm cov ntaub ntawv kev ua tau zoo, A53 cov roj carbon steel yog cov nqi pheej yig dua, ua rau nws xaiv tau nyiaj ntau heev.
Cov Qauv Qauv thiab Cov Muaj Feem Ntau:
Cov kev tsim qauv dav dav thiab cov qauv ua haujlwm thoob ntiaj teb ua kom zoo sib xws thiab yooj yim ntawm kev ua tiav rau cov phiaj xwm kev lag luam.
Cov kev ceev faj
Anti-corrosion yuav tsum:
Galvanized los yog coated nrog kev tiv thaiv kev tiv thaiv thaum raug cov dej ntub lossis thaj chaw uas muaj kev sib xyaw.
Kev Txwv Xeeb Siab
Welded pipe (Type E) is not recommended for high pressure (>20 bar) or high temperature (>350 degree).
Txheem Ua Si:
Thaum kev yuav khoom, nws yog ib qho tsim nyog kom paub meej tias cov khoom siv nrog ASTM A53 daim ntawv pov thawj thiab xeem (xws li kuaj dej siab, tsis yog kev sim dej siab).
Cov ntsiab lus tshwj xeeb:
Ua raws li kev ua ASME B31.1 / B31.3 thiab lwm cov piping cov txheej txheem teeb tsa.
Ntsiab lus:
ASTM A53 Welded Steel Kav, tshwj xeeb tshaj yog qib B, tau siv cov kua roj qis thiab lub teeb yuag, kev lag luam thiab ua haujlwm. Nws yog kev ua tiav rau Seamless Steel kav (xws li A106) lossis high-zog tsim cov kav dej (xws li A500), thiab yog cov khoom siv yooj yim hauv kev lag luam thiab kev tsim khoom noj.
