Lub kauv steel yeeb nkab yog ib tug kauv steel yeeb nkab ua los ntawm cov hlau los yog coils los ntawm kauv-shaped tortuous, thiab nquag welded nrog ob sab thiab welded puab seams thiab sab seams. Rau cov laj thawj hauv qab no, nws tuaj yeem siv dav hauv dej, hluav taws xob, tshuaj lom neeg kev lag luam. Hauv kev tsim cov hauj lwm: Tsuas yog hloov cov kev xav sib txawv, koj tuaj yeem siv cov kav hlau steel nrog cov hlau uas muaj qhov dav dav, uas yooj yim rau kev kho.
Vim tias nws yog ib qho tom qab lwm tus, tus kav ntev ntev ntawm cov kav raj tsis txwv, thiab qhov ntev tuaj yeem txiav txim siab ntawm qhov xav tau. Lub welded kauv yog sib npaug ntawm tag nrho cov kauv raj lub voj voog, yog li cov ntsia hlau raj muaj qhov raug siab thiab muaj zog. Nws yog ib qho yooj yim los hloov cov nplai, haum rau kev tsim cov khoom me me thiab ntau hom kauv raj.
Qhov vuam ntawm cov kav hlau kav yog ntev dua li cov welds ntawm tib tus qauv ncaj nraim. Nyob rau hauv tib tus qauv phab ntsa thickness, cov kauv steel yeeb nkab muaj qhov siab tshaj plaws. Qhov tsis zoo ntawm welded seam ntawm kauv steel yeeb nkab yog "oblique disadvantages". Thaum lub sij hawm siv cov txheej txheem, lub ntsiab kev ntxhov siab ntawm cov yeeb nkab steel, uas yog, qhov ntev ntawm qhov sib npaug qhov tsis zoo ntawm cov yeeb nkab steel axis yog me dua li ntawm cov yeeb nkab ncaj seam; Thib ob, vim hais tias cov raj raj kav hlau dov hlau, thiab cov raj raj hlau yog dov steel phaj, thiab cov raj raj hlau yog dov steel daim hlau, thiab cov raj xa dej steel yog dov steel daim hlau, thiab cov raj xa dej yog dov steel phaj, thiab steel phaj yog dov steel phaj. Qhov cuam tshuam toughness muaj qhov sib txawv loj ntawm kev sib deev, thiab CVN tus nqi nyob rau hauv cov kev taw qhia ntawm cov kev taw qhia dov tuaj yeem yog 3 npaug siab dua li CVN tus nqi perpendicular mus rau dov kev taw qhia.
Cov txheej txheem ntawm cov kav hlau kav yog qhov txawv raws li nws cov peev txheej thiab kev lees paub. Cov ntsia hlau steel yeeb nkab ntawm cov kauv steel yeeb nkab ntawm SY/T5037-2012 yog cov kav dej thauj mus los. Cov kav hlau, thaum GB/T3091-2008 kauv steel kav yog siv rau cov kav dej uas tsis muaj hluav taws xob thauj mus los xws li roj, dej, cua, cua, cua sov, thiab chav.
Tom qab ntawd, nyob rau hauv cov nqe lus ntawm kev lees txais, peb tus qauv spiral steel yeeb nkab kuaj xyuas cov qauv no txawv. GB / T9711 tus qauv kauv steel kav yuav tsum nruj dua SY / T5037 thiab GB / T3091. Nyob rau hauv subordinate ntsia hlau steel yeeb nkab thiab GB / T3091, GB / T3091 kev lees paub yuav tsum nruj dua tus qauv SY / T5037 tus qauv.
Qhov tseeb, peb cov qauv phab ntsa thickness sib txawv yog tib yam. Phab ntsa thickness ntawm phab ntsa thickness yog 5 hli -15 hli. Phab ntsa thickness sib txawv yog ± 1.5 hli.
