Hauv feem ntau cov kev lag luam thiab kev siv siab, carbon steel yeeb nkab yog qhov siv tau ntau dua thiab tus nqi - xaiv tau zoo.Stainless steel feem ntau yuav tsum muaj nyob rau hauv qhov chaw muaj corrosive lossis huv si.Yog tias koj qhov project tsis xav tau corrosion-cov khoom tiv thaiv, CS feem ntau yog qhov nyiam thiab cov peev nyiaj - kev xaiv tus phooj ywg.
Qhov tseem ceeb sib txawv ntawm Carbon Steel thiab Stainless hlau
CS Pipe (Carbon Steel Yeeb Nkab)
Ua los ntawm hlau thiab carbon. Nws paub txog nws lub zog siab thiab ua haujlwm ntev. Cov hom muaj xws li ASTM A106 (siab-temp service) thiab A53 (kev siv dav). Feem ntau coated los yog galvanized los txhim kho corrosion kuj.
SS Tube (Stainless hlau yeeb nkab)
Ua los ntawm cov hlau alloyed nrog qhov tsawg kawg nkaus ntawm 10.5% Chromium, uas tsim ib qho passive, tus kheej - kho oxide txheej uas muab kev tiv thaiv corrosion zoo heev. Cov qib sib xws yog 304 (lub hom phiaj dav dav) thiab 316 (nrog ntxiv molybdenum rau cov tshuaj chloride zoo dua).
| Feature | Carbon hlau (CS) | Stainless hlau (SS) |
| Corrosion Resistance | Nruab nrab; xeb yog uncoated | Zoo heev; naturally resists corrosion |
| Lub zog | Siab tensile zog; zoo tagnrho rau cov qauv / siab | Zoo, tab sis kim dua ib chav tsev zog |
| Cov qauv | ASTM A106, A53, API 5L | ASTM A312, A358, A269 thiab ASTM A312 |
| Daim ntawv thov | Cov kav dej, roj & roj, kev tiv thaiv hluav taws, kev tsim qauv | Tshuaj, khoom noj, marine, huv si |
| Nqi | qis; kev lag luam ntau dua rau cov haujlwm loj | Tus nqi siab dua, tshwj xeeb tshaj yog nyob rau hauv ntau qhov ntau |
Yog tias koj xaiv carbon steel yeeb nkab lossis stainless hlau yeeb nkab rau koj qhov project, thov koj xav tiv taujtiv tauj pebthiab muab cov qauv, qhov ntau thiab tsawg, thiab ntau npaum li cas koj xav tau rau kev tsocai sai
Cov ntsiab lus tseem ceeb los txiav txim siab "Qhov twg zoo dua?"
Xaiv CS yeeb nkab yog:
- Ib puag ncig yog qhuav thiab tsis yog -corrosive (cov kav dej hauv tsev, qee qhov qauv tsim).
- Qhov kev txhawj xeeb tseem ceeb yog lub zog muaj zog lossis siab siab (lub tsev txhawb nqa, siab -cov kab hluav taws xob siab).
- Cov yeeb nkab yuav muab faus lossis kos rau hauv pob zeb (nrog cov txheej tiv thaiv zoo / qhwv).
- Feem ntau ua haujlwm nyob rau hauv qhov chaw uas tsis muaj corrosive (xws li dej thiab dej ntws, kev tsim kho scaffolding, qis-cov roj thiab cov kav dej uas muaj kev tiv thaiv kev tiv thaiv corrosion).
- Tshwj xeeb tshaj yog thaum muaj zog txhua yam yuav tsum tau thiab cov nqi tswj tau txiav txim siab.
Xaiv SS yeeb nkab yog tias:
- Kev tiv thaiv corrosion yog qhov tseem ceeb (tshwj xeeb rau dej, huab cua, ntsev, tshuaj, lossis kua qaub / alkaline).
- Kev tu cev thiab kev huv huv yog qhov tseem ceeb (kev ua zaub mov & dej haus, cov chaw muag tshuaj, cov roj hluav taws xob kho mob, khoom noj siv mis, breweries).
- Kev saib xyuas qis thiab kev ua neej nyob ntev yog muaj nuj nqis tshaj tus nqi pib (kev siv vaj tse, cov qauv hauv ntug dej hiav txwv).
- Daim ntawv thov muaj cov tshuaj corrosive (cov nroj tsuag tshuaj, petrochemicals nrog H2S, marine ib puag ncig).
Cov ntawv thov siv
CS cev: Lub tsev thav duab, cov dej hauv av / roj av (galvanized), kev tiv thaiv hluav taws kub hnyiab, cov kav dej boiler, cov kav dej hauv tsev, laj kab, tes tuav.
SS Tub: Tshuaj ua cov kav dej, dej hiav txwv desalination nroj tsuag, chav ua noj tso cua tshuab, cov khoom siv tshuaj, architectural facades thiab handrails, phais ntsuas kev tsim khoom, pulp & ntawv mills.
Hauv cov ntsiab lus: Tsis muaj universal "zoo dua."
Rau tus nqi - muaj zog zoo nyob rau hauv ib puag ncig tswj → Carbon Steel (CS) yeeb nkab zoo dua.
Rau qhov ntev - kev ua tau zoo nyob rau hauv ib puag ncig corrosive los yog tu cev → Stainless hlau (SS) yeeb nkab yog zoo dua.
