Hauv lub neej niaj hnub,carbon steel tube (cs tube)thiabstainless hlau tube (ss tube)yog ib qho ntawm cov khoom siv feem ntau siv cov kav dej. Txawm hais tias lawv ob leeg siv los thauj cov pa roj thiab kua, lawv cov ntaub ntawv sib txawv. Tsab ntawv xov xwm no yuav ua kom muaj kev soj ntsuam ntxaws ntxaws ntawm cov khoom sib txawv thiab daim ntawv thov ntawm cov pa roj carbon steel raj thiab stainless hlau raj los ntawm plaub yam.

1. Tshuaj muaj pes tsawg leeg
Cov khoom tseem ceeb ntawm carbon steel raj yog carbon thiab hlau, muaj 1.5% carbon. Cov khoom tseem ceeb ntawm stainless hlau raj yog hlau, chromium, npib tsib xee thiab cov pa roj carbon tsawg. Yog li ntawd, stainless hlau raj tsis tsuas yog muaj cov khoom siv ntawm cov hlau zoo tib yam, tab sis kuj muaj qhov zoo corrosion kuj.

Vim qhov sib txawv ntawm lawv cov tshuaj muaj pes tsawg leeg, carbon steel tubes muaj zog dua thiab hardness, thaum stainless hlau hlab muaj zoo corrosion kuj. Yog li ntawd, lawv qhov kev ua tau zoo sib txawv yog pom tseeb hauv lawv cov kev siv tshwj xeeb.

2. Tus nqi thiab kev ruaj ntseg
Stainless hlau raj yog kim dua li carbon steel raj. Los ntawm tus nqi thiab kev saib xyuas kev saib xyuas, cov kav dej carbon steel muaj tus nqi zoo dua cov hlau tsis muaj steel vim tias lawv cov khoom siv raw thiab cov nqi tsim khoom qis dua cov hlau stainless. Tsis tas li ntawd, carbon steel tubes kuj yooj yim rau kev tswj thiab hloov vim txo nqi kho thiab yooj yim ntawm machining.

Stainless hlau raj yog qhov nyuaj rau tshuab thiab kho, yog li nws kim dua los tsim thiab kho dua li carbon steel raj. Tsis tas li ntawd, qhov sib txawv ntawm ntau hom stainless hlau raj kuj tseem loj, thiab kev xaiv thiab kev teeb tsa ntawm stainless hlau raj yuav tsum tau txiav txim siab ntau dua.

3. Mechanical zog
Hais txog cov khoom siv kho tshuab, kuj tseem muaj qee qhov sib txawv ntawm cov pa roj carbon steel raj thiab stainless hlau raj. Cov pa roj carbon steel tubes muaj zog dua thiab hardness, yog li lawv zoo dua li cov hlau tsis muaj steel hlau rau kev siv hauv qhov kub siab thiab kub ib puag ncig. Stainless hlau tubes tsis muaj zog nyob rau hauv cov nqe lus ntawm lub zog thiab hardness, tab sis muaj ntau ductile thiab corrosion-resistant dua carbon steel hlab.

Tsis tas li ntawd, cov hlau tsis muaj steel hlau yog cov ductile ntau dua li cov pa roj carbon steel hauv cov ntsiab lus ntawm cov tshuab deformation xws li bending thiab twisting, yog li lawv tau siv ntau dua hauv aviation thiab aerospace teb thiab hauv kev lag luam tshuaj vim lawv zoo corrosion kuj nyob rau hauv huab ib puag ncig.

4. Daim ntawv thov teb

Carbon steel raj feem ntau yog siv rau hauv cov xwm txheej hauv qab no:

Kev xa cov kua dej kub thiab siab siab
Raws li ib tug load-bearing tswv cuab ntawm ib lub tsev
Raws li lub cev pob txha ntawm steel qauv thiab tsheb
Qhov cua qhov ducts rau cov tsev thiab cov ducts rau cua tuav tshuab

Stainless hlau raj feem ntau yog siv dav hauv cov xwm txheej hauv qab no:

Kev lag luam tshuaj
Kev lag luam kws tshuaj
kev lag luam marine
kev lag luam zaub mov
Qhov no yog vim cov hlau tsis muaj steel hlau zoo dua corrosion kuj thiab toughness, thiab muaj peev xwm tiv taus ib puag ncig hnyav.

5. Xaus:

Txhawm rau ua kom tiav, muaj qee qhov sib txawv ntawm cov pa roj carbon steel raj thiab stainless hlau raj ntawm cov khoom, nqi, cov khoom siv kho tshuab thiab daim ntawv thov. Yog li ntawd, peb yuav tsum xaiv cov khoom lag luam uas tsim nyog tshaj plaws raws li kev thov tshwj xeeb scenario. Yog lawm, thaum xaiv cov khoom siv kav dej, peb yuav tsum tsis tsuas yog xav txog peb tus kheej cov kev xav tau xwb, tab sis kuj tseem ua tib zoo saib xyuas cov yam ntxwv xws li corrosion thiab siab uas cov khoom siv hauv cov kav dej yuav ntsib, thiaj li ua kom muaj kev nyab xeeb thiab siv mus ntev ntawm cov kav dej.
