Welded steel yeeb nkab, tseem hu ua welded yeeb nkab, yog cov yeeb nkab steel ua los ntawm cov hlau los yog cov hlua hlau uas tau welded tom qab tau curled thiab tsim. Cov txheej txheem ntau lawm ntawm welded steel kav yog qhov yooj yim, qhov kev ua tau zoo yog siab, muaj ntau ntau yam thiab cov kev qhia tshwj xeeb, thiab cov cuab yeej siv nyiaj tsawg, tab sis lub zog dav dav yog qis dua li ntawm seamless steel kav. Txij li thaum xyoo 1930, nrog rau kev loj hlob sai ntawm kev sib txuas ua ke ntawm cov hlau zoo thiab kev nce qib ntawm vuam thiab tshuaj xyuas tshuab, qhov zoo ntawm welds tau txuas ntxiv txhim kho, thiab ntau yam thiab cov ntsiab lus ntawm cov kav hlau welded tau nce ib hnub. , hloov cov kav hlau tsis tiav hauv ntau qhov chaw. Sewing steel yeeb nkab. Welded steel kav yog muab faib ua ncaj seam welded kav thiab kauv welded kav raws li daim ntawv ntawm weld.
Cov txheej txheem ntau lawm ntawm txoj kab ncaj nraim welded yeeb nkab yog qhov yooj yim, qhov kev ua tau zoo yog siab, tus nqi qis, thiab kev loj hlob sai. Lub zog ntawm kauv welded kav feem ntau yog siab tshaj qhov ncaj seam welded kav. Welded kav nrog cov kab uas loj dua tuaj yeem tsim los ntawm cov kab nqaim, thiab cov kav dej uas muaj cov kab sib txawv kuj tuaj yeem tsim los ntawm cov ntawv loj ntawm tib qhov dav. Txawm li cas los xij, piv nrog cov kav hlau ncaj ncaj ntawm tib qhov ntev, qhov ntev ntawm qhov vuam yog nce los ntawm 30 ~ 100%, thiab cov khoom ceev yog qis dua. Yog li ntawd, me me welded kav feem ntau siv ncaj seam welding, thaum loj txoj kab uas hla welded kav feem ntau siv kauv vuam.
Welded steel kav rau kev thauj mus los ntawm cov dej tsis tshua muaj siab (GB/T3091-2008) kuj yog hu ua cov kav dej dav dav, feem ntau hu ua cov kav dej dub. Nws yog welded steel yeeb nkab siv los thauj dej, roj, huab cua, roj, cua sov chav thiab lwm yam dej siab thiab lwm yam. Cov phab ntsa tuab ntawm cov yeeb nkab steel sib txuas tau muab faib ua cov kav hlau zoo tib yam thiab cov kav hlau tuab tuab; cov ntaub ntawv txuas kawg tau muab faib ua cov kav hlau tsis muaj hlau (cov kav dej dawb) thiab cov kav hlau threaded. Ntxiv nrog rau kev siv ncaj qha los thauj cov kua dej, welded steel kav rau kev thauj mus los ntawm cov dej tsis tshua muaj siab kuj tau siv dav los ua cov kav dej qub rau cov kav dej galvanized welded steel kav rau kev thauj cov kua dej tsawg.
1. Galvanized welded steel yeeb nkab rau kev thauj mus los tsis tshua muaj siab (GB / T3091-2008) kuj hu ua galvanized electric welded steel yeeb nkab, feem ntau hu ua cov yeeb nkab dawb. Nws yog kub-dip galvanized welded (lub qhov cub welded los yog hluav taws xob welded) steel yeeb nkab siv los thauj dej, roj, roj cua, cua sov chav dej, dej sov thiab lwm yam dej ntws los yog lwm lub hom phiaj. Cov phab ntsa tuab ntawm cov yeeb nkab steel txuas tau muab faib ua cov yeeb nkab zoo tib yam galvanized steel yeeb nkab thiab cov yeeb nkab tuab galvanized steel yeeb nkab; Daim ntawv kawg kev sib txuas yog muab faib ua cov yeeb nkab uas tsis yog xov galvanized steel thiab threaded galvanized steel yeeb nkab. Cov kev qhia tshwj xeeb ntawm cov yeeb nkab steel yog qhia nyob rau hauv nominal txoj kab uas hla (mm), uas yog kwv yees tus nqi ntawm lub puab kab. Nws yog kev cai los qhia nws hauv nti, xws li 1/2, 3/4, 1, 2, thiab lwm yam.
2 Ordinary carbon steel hlau casing (YB/T5305-2006) yog cov yeeb nkab steel siv los tiv thaiv cov xov hlau hauv cov khoom siv hluav taws xob xws li kev lag luam thiab pej xeem cov tsev thiab kev teeb tsa cov tshuab thiab khoom siv.
3. Ncaj seam hluav taws xob welded steel yeeb nkab (GB/T13793-2008) yog cov yeeb nkab steel nrog cov vuam seam sib npaug mus rau qhov ntev ntawm cov yeeb nkab steel. Nws yog siv rau cov qauv dav dav thiab feem ntau yog muab faib ua metric fais welded steel kav, hluav taws xob welded nyias-walled kav, thiab lwm yam.
4. Kauv submerged arc welded steel yeeb nkab (SY/T5037-2000) rau kev thauj mus los ntawm cov kua dej siab yog ua los ntawm kub dov steel strip coils raws li cov yeeb nkab blanks, uas yog spirally tsim ntawm qhov kub thiab txias thiab welded los ntawm ob sab. submerged arc vuam. Lawv yog siv rau cov kua dej siab. Kauv seam steel yeeb nkab rau kev thauj mus los. Cov kav hlau steel muaj lub zog siab-cov kabmob muaj peev xwm thiab kev ua haujlwm vuam zoo. Lawv tau dhau los ua ntau yam kev soj ntsuam thiab kev sim thiab muaj kev nyab xeeb thiab txhim khu kev qha. Cov yeeb nkab steel muaj txoj kab uas hla loj, kev thauj mus los zoo, thiab tuaj yeem txuag kev nqis peev hauv kev tso cov kav dej. Feem ntau yog siv rau cov kav dej thauj cov roj thiab cov nkev.
5. Kauv seam high-frequency welded steel yeeb nkab (SY/T5038-2000) rau kev thauj mus los ntawm cov kua dej siab yog ua los ntawm kub dov steel strip coils raws li cov yeeb nkab blanks, spirally tsim ntawm qhov kub thiab txias, thiab welded los ntawm high- zaus lap welding. Nws yog siv rau siab-bearing Kauv seam siab zaus welded steel yeeb nkab rau cov dej thauj. Cov kav hlau muaj lub zog siab-cov kabmob muaj peev xwm, zoo plasticity, thiab yooj yim rau vuam thiab txheej txheem. Tom qab ntau yam kev soj ntsuam nruj thiab kev tshawb fawb thiab kev sim, lawv muaj kev nyab xeeb thiab txhim khu kev ntseeg siv. Cov yeeb nkab steel muaj cov kab loj loj, kev thauj mus los zoo, thiab tuaj yeem txuag kev nqis peev hauv kev tso cov kav dej. Feem ntau yog siv los tso cov kav dej thauj cov roj, cov pa roj, thiab lwm yam.
7. Kauv seam high-frequency welded steel yeeb nkab (SY/T5039-2000) rau kev thauj mus los ntawm cov dej uas tsis tshua muaj siab yog ua los ntawm kub dov steel strip coils raws li cov yeeb nkab blanks, uas yog spirally tsim ntawm qhov kub thiab txias thiab welded los ntawm high-frequency lap welding rau kev thauj mus los uas tsis tshua muaj siab. Siv kauv seam siab zaus vuam ntawm cov kav dej steel.
8. Kauv welded steel yeeb nkab rau pawg (SY/T5768-2000) yog ua los ntawm kub dov steel strip coils raws li cov yeeb nkab blanks, spirally tsim ntawm qhov kub thiab txias, thiab ua los ntawm ob sab submerged arc vuam los yog high-frequency. vuam. Nws yog siv rau kev tsim kho vaj tse thiab chaw nres nkoj. , txuas hniav thiab lwm yam hauv paus pawg nrog cov kav hlau.
