Teem sijhawm 40 carbon steel kav yog categorized raws li kev sib xyaw ua ke nrog rau txoj kab uas hla-rau-phab ntsa thickness piv, cov khoom siv zog, sab nraud, phab ntsa thickness, thiab lub peev xwm siab.
Lub sijhawm teem sijhawm, xws li Schedule 40, qhia txog kev sib xyaw ua ke ntawm cov xwm txheej no.Rau Teem caij 40 kav dej, lawv feem ntau muaj qhov nruab nrab ntawm phab ntsa tuab, tawm tsam qhov sib npaug ntawm lub zog thiab qhov hnyav.Qhov hnyav ntawm cov yeeb nkab tuaj yeem sib txawv raws li qhov tshwj xeeb ntawm cov pa roj carbon steel siv, txoj kab uas hla, thiab phab ntsa thickness.
Ntxiv cov pa roj carbon rau cov hlau tuaj yeem cuam tshuam qhov hnyav, nrog cov ntsiab lus carbon ntau dua ua rau cov kav dej sib dua.Txawm li cas los xij, ob lub phab ntsa thickness thiab txoj kab uas hla kuj ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov hnyav.
Teem sijhawm 40 yog suav tias yog chav kawm siab nruab nrab, haum rau ntau yam kev siv uas yuav tsum tau muaj kev ntsuas siab.Yog tias koj xav tau cov ntaub ntawv ntxaws ntxaws lossis kev pab cuam txog Teem sijhawm 40 carbon steel kav, thov hu rau peb kom tau txais kev pab ntxiv.

Teem sijhawm 40 carbon steel yeeb nkab yog tus qauv yeeb nkab loj tsim siv hauv kev tsim kho kev lag luam.Nws hais txog qhov tuab ntawm cov yeeb nkab phab ntsa thiab yog ib feem ntawm cov txheej txheem siv los faib cov kav dej raws li lawv cov phab ntsa thickness thiab lub peev xwm siab.
Hauv Schedule 40 system:
- Lub "Tsev" yog hais txog phab ntsa thickness ntawm cov yeeb nkab.
- "Carbon steel" qhia cov khoom muaj pes tsawg leeg ntawm cov yeeb nkab, uas feem ntau yog carbon thiab hlau.
Teem sijhawm 40 carbon steel kav feem ntau siv rau ntau yam kev siv, suav nrog kev thauj mus los hauv dej thiab roj, kev txhawb nqa, thiab kev lag luam dav dav.Lawv paub txog lawv lub zog, durability, thiab versatility, ua rau lawv nyiam nyob rau hauv ntau yam kev tsim kho thiab engineering tej yaam num.
Tshuaj muaj pes tsawg leeg ntawm Schedule 40 Carbon Steel Pipe
Teem sijhawm 40 yuav muaj qee qhov kev txiav txim siab tuab, tsis hais qib tshwj xeeb lossis muaj pes tsawg leeg ntawm cov hlau siv.
