Teem caij 40 Vs Teem caij 80 Galvanized Steel Yeeb Nkab: Qhov sib txawv, Siab, Qhov hnyav & kev siv

"Schedule" (Sch) hais txog qhovphab ntsa thickness ntawm cov yeeb nkab, tsis yog sab nraud.

Lub sijhawm teem sijhawm siab dua=phab ntsa tuab dua=muaj peev xwm siab dua

Tib txoj kab uas hla sab nraud, txawv sab hauv txoj kab uas hla

Yog li:

Teem sijhawm 40=txheem phab ntsa thickness

Teem sijhawm 80=thicker, muaj zog phab ntsa thickness

Galvanized steel yeeb nkab yog carbon steel yeeb nkab coated nrog zinc los ntawmkub-dip galvanizing, kev txhim kho:

Corrosion kuj

Sab nraum zoov durability

Kev pab lub neej nyob rau hauv ib puag ncig humid

Cov qauv uas muaj xws li:

ASTM A53

ASTM A106 (ncej-galvanizing)

ASTM A123 (Zinc txheej txheem)

👉 Tseem ceeb:
Cov txheej galvanizing yogzoo ib yam, mas covpuag steel thickness txawv.

👉 Qhov tshwm sim:

SCH 80=~40% phab ntsa tuab

Zoo dua raumechanical zog + siab tsis kam

Teem caij 40 Galvanized yeeb nkab

Haum rau:

Cov khoom siv dej

Kev ywg dej

Tsawg- cov kab hluav taws xob siab

Hom kev siv:Chaw nyob & lub teeb industrial

Teem sijhawm 80 Galvanized Yeeb Nkab

Tsim los rau:

High -siab tshuab

Industrial pipelines

Mechanical & structural load

Hom kev siv:Heavy-cov haujlwm ua haujlwm ib puag ncig

Ob leeg muajzoo li corrosion tiv thaivvim:

Tib txheej txheem galvanizing (zinc txheej ~ 40-100 μm)

Tib yam los tiv thaiv- xeb mechanism (txheej zinc txheej)

👉 Txawm li cas los xij:
Teem sijhawm 80 siv sijhawm ntev dua hauv qhov chaw hnyav vim tias:

Thicker steel=qeeb corrosion nkag

👉 Kev cuam tshuam:

SCH 80 → muaj zog tab sis siab dua kev thauj mus los & kev teeb tsa tus nqi

SCH 40 → yooj yim tuav

Siab - cov kab dej siab

Marine & offshore structures

Mechanical support structures

XaivTeem caij 40yog:

Koj xav tau tus nqi -piping zoo

Qhov system siab yog qis rau nruab nrab

Installation ceev tseem ceeb

XaivTeem caij 80yog:

Kev kub siab lossis kev thauj khoom yog koom nrog

Ib puag ncig hnyav (marine, industrial)

Lub neej ua haujlwm ntev yog qhov tseem ceeb

Cov kws tshaj lij galvanized yeeb nkab xa khoom feem ntau ua:

Zinc txheej thickness test (ASTM A123)

Kev ntsuas hydrostatic siab

Dimensional soj ntsuam (OD, WT kam rau ua)

Kev kuaj qhov adhesion

Thib peb-kev soj ntsuam tog (SGS / BV / TUV)

1. Puas yog Schedule 80 galvanized yeeb nkab zoo dua li Schedule 40?

Nws muaj zog dua thiab ruaj khov dua, tab sis tsis tas yuav tsim nyog tshwj tsis yog tias muaj kev kub ntxhov lossis hnyav - yuav tsum siv lub luag haujlwm.

2. Puas yog SCH 40 thiab SCH 80 muaj qhov sib txawv ntawm galvanizing?

Tsis yog. Cov txheej txheem zinc txheej yog tib yam; tsuas yog phab ntsa thickness txawv.

3. Qhov twg nyob sab nraum zoov ntev dua?

Ob leeg tiv thaiv corrosion zoo, tab sis SCH 80 feem ntau kav ntev dua vim cov hlau tuab.

4. SCH 40 puas tuaj yeem ua haujlwm siab?

Nws tuaj yeem tswj tau qhov siab nruab nrab, tab sis SCH 80 tau pom zoo rau siab - cov tshuab siab.

5. Vim li cas SCH 80 thiaj kim dua?

Vim tias nws siv cov khoom siv hlau ntau dua thiab muaj qhov hnyav dua.
