Thaum nws los txog rau kev siv cov kev daws teeb meem, ob nqe lus feem ntau tshwm sim:Cov Yeeb Nkab Hlau DubthiabCov Yeeb Nkab HlauCov. Thaum xub thawj siab ib muag, lawv yuav zoo sib xws li vim ob qho tib si yog tsim los ntawm cov hlau. Txawm li cas los xij, lawv cov yam ntxwv, tsho xim, thiab siv lawv ua kom sib nrug. Nkag siab txog cov kev sib txawv no yog qhov tseem ceeb rau cov engineers, cov neeg yuav khoom, thiab cov neeg yuav khoom uas xav xaiv cov khoom uas haum tshaj plaws rau lawv cov dej num.
Raws li ib qho ntawm cov thawj coj ua lag luam hauv Suav teb,HUAYANG STEEFF YEEB NKABMuab ntau yam ntawm ERW, LSAW, SSAW, thiab seamless kav dej hauv ob pawg dub thiab cov roj carbon steel. Kab lus no muaj cov ncauj lus piav qhia ntxaws ntawm cov yeeb nkab dub vs cov yeeb nkab steel, tsom mus rau lawv cov khoom, cov kev siv, thiab kev lag luam.
Dab tsi yog cov yeeb nkab steel dub?
Cov Yeeb Nkab Hlau DubHais txog cov pa roj hlau steel uas tsis tau galvanized lossis coated nrog lwm cov khaubncaws sab nraud pov hwm. Cov "dub" tshwm sim los ntawm cov hlau oxide teev tsim thaum lub sijhawm tsim khoom.
- Cov Khoom Siv Cov Khoom Siv: Feem ntau cov hlau uas muaj cov ntsiab lus carbon nruab nrab.
- Nplaim: Tsaus, matte ua tiav vim yog cov oxide txheej.
- Cov txheej txheem tsim khoom: Nquag tsim los ntawm ERW (hluav taws xob tiv taus welded) los yog seamless cov txheej txheem.
- Lub zog: Siv {-}} Ua tau zoo, muaj zog, thiab muaj.
- Kheev kheev tsis muaj zog: Raug rau kev xeb yog tias raug rau cov dej noo lossis tshuaj lom neeg yam tsis muaj kev kho mob tiv thaiv.
Dub hlau kav hlau yog feem ntau siv nyob rau hauv qis {{0} h siab thiab sab hauv cov ntaub ntawv cog, thiab dej los nyob rau hauv cov chaw tswj.
Dab tsi yog cov yeeb nkab carbon hlau?
Cov Yeeb Nkab Hlauyog ib pawg dav dav uas suav nrog cov yeeb nkab steel uas muaj cov carbon ua cov khoom siv tseem ceeb. Nyob ntawm qhov feem pua ntawm cov pa roj carbon, carbon steel tuaj yeem muab cais ua peb hom loj:
- Tsawg Daim Hlau(txog li 0.25% carbon): siab ductility, yooj yim rau daim, weldability zoo.
- Nruab Nrab Cov Hlau(0.25% - 0.60% carbon): Muaj zog dua, haum rau kev siv tshuab thiab kev siv tshuab cov ntaub ntawv.
- Cov Roj Hlau Siab(0.60% - 2.0% carbon): muaj zog heev thiab nyuaj tab sis tsawg dua coo, feem ntau siv hauv cov khoom lag luam tshwj xeeb.
Cov pa roj carbon cov kav hlau tuaj yeem muab rau hauv cov xim dub (tsis muaj txiaj ntsig) lossis galvanized (zinc - coated) ua tiav) tiav. Qhov no ua rau lawv ntau yam ntau dua li dub steel kav dej, raws li lawv tuaj yeem yoog kom haum rau cov chaw hnyav thiab qhov kev thov siab.
Qhov sib txawv ntawm cov yeeb nkab dub thiab cov yeeb nkab steel
Txhawm rau kom meej qhov sib txawv, ntawm no yog ib sab -- sab sib piv:
| Yam | Cov Yeeb Nkab Hlau Dub | Cov Yeeb Nkab Hlau |
|---|---|---|
| Zaj piav | Ib hom kev siv roj carbon hlau tsis muaj galvanization | Ib qeb ntawm cov kav hlau nrog vians sib txawv |
| Nplaim | Tsaus ntuj, oxidized tiav | Tuaj yeem ua dub (oxidized) lossis galvanized (zinc - txheej) |
| Lub zog | Nruab Nrab, haum rau qes - siab} cov tshuab siab | Dav ntau ntawm lub zog, haum rau high - qhov siab thiab cov qauv tsim |
| Corrosion Kuj | Tsawg, nquag mus rau xeb tsis muaj txheej | Zoo dua yog galvanized lossis kho; tseem xav tau kev tiv thaiv hauv cov xwm txheej hnyav |
| Cov Ntawv Thov | Roj Pipelines, Cov Hluav Taws Xob Hluav Taws Xob, Khoom Siv Dej | Roj & Roj, Petrochemical, Cov Cuab Yeej Siv Cov Txheej Txheem, Cov Nroj Hluav Taws Xob |
| Tus nqi | Qis dua tus nqi | Cov nqi siab dua nyob ntawm qib thiab kev kho, tab sis ntev lifespan |
Los ntawm cov lus no, nws yog qhov tseeb tias thaum lub sijhawm dub steel yog ib subset,Cov Yeeb Nkab Hlausawv cev ib qho ntau dav thiab muaj cov qeb hloov tau.
Cov ntawv thov ntawm cov kav hlau dub hlau
Dub hlau kav hlau yog feem ntau siv nyob rau hauvTsawg - h siab, sab hauv tsev, lossis ib puag ncig qhuavQhov twg corrosion kev pheej hmoo yog txwv. Cov ntawv thov raug muaj xws li:
- Cov nkev thauj khoom nyob rau hauv cov chaw nyob lossis cov tsev lag luam
- Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob thiab Kev Tiv Thaiv Hluav Taws Kub
- Tsawg - qhov siab dej pipelines
- General Kev Tsim Kho Cov Qauv
Vim tias cov hlau dub yog pheej yig thiab yooj yim rau weld, feem ntau nws feem ntau tau xaiv rau cov phiaj xwm qhov kev tswj kev siv nyiaj txiag yog qhov tseem ceeb.
Cov ntawv thov ntawm cov kav dej hlau steel
Carbon Steel Kav, tshwj xeeb tshaj yog thaum Galvanized lossis coated, yog tsim rauhnyav {{0 {}} duty thiab siab - qhov siab muaj kev lag luam sivCov. Cov ntawv thov feem muaj xws li:
