Kab Yeeb Hlau Yeeb Nkab yog cov kav dej siv los thauj cov pa roj thiab kua. Cov kab yeeb nkab tuaj yeem tiv taus kev thauj mus los huv hauv cov xwm txheej hnyav xws li kev kub siab, kub thiab xeb, yog li nws tau siv dav hauv roj av, roj av, tshuaj lom neeg kev lag luam, kev txuag dej, aviation, aerospace thiab lwm yam kev lag luam.
Cov qauv siv thoob ntiaj teb rau kab yeeb nkab steel kav yog API5L thiab ISO3183.
API5L yog tus qauv kev lag luam tsim los ntawm American Petroleum Institute (API) rau kev lag luam roj thiab roj. Cov qauv no suav nrog cov qauv tsim, tsim khoom thiab kuaj cov qauv ntawm ntau cov kav hlau, nrog rau cov ntaub ntawv muaj feem xyuam, kev ua thiab xa khoom, thiab lwm yam. Cov ntaub ntawv tseem ceeb yog PSL1, PSL2:
GRB, X42, X46, X52, X56, X60, X65, X70
(L245, L290, L320, L360, L415, L390, L450, L485).
ISO3183 yog tus qauv tsim los ntawm International Organization for Standardization (ISO) rau kev lag luam roj thiab roj, thiab tseem siv rau hauv lwm qhov chaw lag luam. Cov ntaub ntawv tseem ceeb yog:
PSL1, PSL2:
BNE, X42NE, X52NE, X60NE, X65QE, X65ME, X70QE, X70ME, X80ME
(L245NE, L290NE, L360NE, L415NE, L450QE, L450ME, L485QE, L485ME).
Kab yeeb nkab haum rau seamless thiab welded steel kav raws li hauv qab no:
SMLS: Seamless yeeb nkab
SAW: Submerged-arc Welding
SAWL: Submerged-arc Longitudinal welded yeeb nkab
SAWH: Submerged-arc helical welded yeeb nkab
HFW: High-frequency welded yeeb nkab
EW: Hluav taws xob welded yeeb nkab
COWL: Combination Longitudinal welded yeeb nkab
Kab yeeb nkab steel kav tau dav siv thoob ntiaj teb thiab dhau los ua cov khoom tseem ceeb hauv kev lag luam niaj hnub thiab lub neej:
1. Lub hom phiaj tseem ceeb ntawm txoj kab yeeb nkab yog thauj cov kua dej xws li roj thiab cov pa roj.
2. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, cov kab yeeb nkab steel yeeb nkab kuj tau siv dav hauv lwm qhov chaw, xws li kev thauj dej hauv hydraulic engineering, thauj cov tshuaj hauv kev lag luam tshuaj, thiab txawm siv hauv cov dej txias hauv nuclear fais fab nroj tsuag. Nws txoj kev tsim khoom nruj thiab kev sim cov qauv, lub zog siab, thiab kev tiv thaiv corrosion muab linepipe steel kav kev ua tau zoo hauv ntau yam kev lag luam hnyav thiab ib puag ncig.
3. Kab yeeb nkab kuj tau siv dav hauv kev tsim kho kev lag luam, nrog kev nyab xeeb thiab kev ntseeg tau zoo heev.
