Qhia:
Kauv welded yeeb nkab yog ib qho tseem ceeb nyob rau hauv ntau yam kev tsim kho vaj tse, nrog rau cov roj thiab cov kav dej, cov dej xa dej, thiab kev siv cov txheej txheem.Raws li nrog rau cov khoom tsim kho, cov kev qhia tshwj xeeb yuav tsum tau ua raws li txhawm rau ua kom muaj txiaj ntsig thiab kev ntseeg siab ntawm cov kav dej no.Nyob rau hauv no blog, peb yuav delve rau hauv intricacies ntawmkauv welded yeeb nkab specificationslos muab cov lus qhia dav dav kom nkag siab zoo dua cov khoom lag luam tseem ceeb no.
1. Kev txhais thiab qhov zoo:
Txoj kev tsim khoom ntawmkauv welded yeeb nkabyog los vuam cov kub dov steel sawb mus rau hauv ib tug kauv zoo los ntawm nruam kauv forming.Lub sawb npoo tau koom ua ke siv ob-sided submerged arc vuam (DSAW) los tsim ib tug high-lub zog yeeb nkab nrog enhanced durability thiab kuj rau deformation.Lub ntsiab zoo ntawm kauv welded yeeb nkab muaj xws li cov qauv kev ntseeg tau zoo, lub zog tsis sib xws raws li qhov ntev ntawm cov yeeb nkab, thiab muaj peev xwm tiv taus siab sab hauv.
2. Txoj kab uas hla thiab phab ntsa thickness:
Cov specifications ntawm kauv welded kav muaj xws li ntau yam tsis, qhov tseem ceeb tshaj plaws ntawm uas yog txoj kab uas hla thiab phab ntsa thickness ntawm cov yeeb nkab.Cov qhov ntev no nyob ntawm qhov xav tau ntawm daim ntawv thov thiab kev ua haujlwm.Feem ntau hais lus, kauv welded yeeb nkab yog muaj nyob rau hauv ib txoj kab uas hla loj dua seamless los yog ncaj seam welded yeeb nkab, feem ntau yog li ntawm 8 ntiv mus rau 126 ntiv tes (203.2 mus rau 3200 hli) los yog loj dua.Phab ntsa thickness ranges ntawm 6 hli mus rau 25.4 hli los yog ntau tshaj.
3. Steel qib thiab tshuaj muaj pes tsawg leeg:
Kev xaiv ntawm qib steel thiab tshuaj lom neeg muaj pes tsawg leeg ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov khoom siv kho tshuab thiab kev tiv thaiv corrosion ntawm cov kav welded kav.Feem ntau siv cov qib steel rau cov kav kav dej muaj xws li API 5L X series, ASTM A252 qib 2 thiab 3, thiab ASTM A139 qib B thiab C. Cov qib steel no tau txiav txim siab raws li cov khoom siv zog thiab cov pa roj carbon sib npaug los xyuas kom muaj kev ua tau zoo hauv kev siv tshwj xeeb.
4. Kev kuaj thiab tshuaj xyuas:
Txhawm rau kom ntseeg tau tias qhov zoo thiab kev ntseeg siab ntawm cov kav welded kav, cov chaw tsim khoom ua raws li cov txheej txheem nruj thiab tshuaj xyuas.Cov kev ntsuam xyuas tseem ceeb ua tau suav nrog kev sim hydrostatic, kev sim tsis muaj kev puas tsuaj (xws li kev tshuaj xyuas ultrasonic lossis radiographic) thiab kev sim tshuab (tensile, yield thiab impact testing).Cov kev ntsuam xyuas no ua kom cov kav dej ua tau raws li qhov yuav tsum tau muaj zog, qhov loj me thiab cov qauv xau.
5. Txheej txheej thiab tiv thaiv:
Txhawm rau tiv thaiv kauv welded kav los ntawm corrosion thiab lwm yam sab nraud, muaj ntau yam txheej txheej txheej.Cov txheej txheem no yuav suav nrog epoxy, thee tar enamel lossis polyethylene, thiab lwm yam.Tsis tas li ntawd, cov txheej txheem tiv thaiv cathodic xws li kev txi anodes lossis cov tshuab tam sim no tuaj yeem siv los tiv thaiv cov kav dej.
Hauv kev xaus:
Nkag siab txog cov ntsiab lus ntawm kauv welded yeeb nkab yog qhov tseem ceeb rau cov engineers, tus thawj tswj xyuas qhov project thiab cov neeg muaj feem koom nrog hauv cov phiaj xwm infrastructure.Los ntawm kev txiav txim siab txoj kab uas hla, phab ntsa thickness, qib steel, kev sim thiab kev tiv thaiv saum npoo, koj tuaj yeem xyuas kom meej tias cov yeeb nkab ua tau raws li cov qauv kev ua tau zoo.Kev ua raws li cov cai tsis yog tsuas yog ua kom lub neej ntev thiab kev nyab xeeb ntawm koj cov kav dej, tab sis kuj ua kom muaj kev thauj mus los ntawm cov kua, roj thiab lwm yam khoom siv.Los ntawm kev saib xyuas kom meej, engineers thiab cov neeg muaj feem cuam tshuam tuaj yeem ua tiav qhov kev ua tau zoo thaum ua tau raws li cov qauv kev lag luam thiab cov cai.
