Hauv kev ua haujlwm ntawm cov kav hlau steel rau loj - nplai engineering cov haujlwm, LSAW steel kav siv dav siv tsis yog vim lawv lub npe "Longitudinal Submerged Arc Welded" lossis cov txheej txheem tsim khoom, tab sis vim muaj cov txheej txheem txheej txheem logic nyob rau hauv kev tswj kom zoo. Piv nrog rau cov kav hlau welded zoo tib yam, LSAW steel kav muaj cov kev xav tau siab dua hauv kev xaiv cov khoom, kev tsim, kev tswj vuam, thiab kev tshuaj xyuas.
Pib los ntawm cov txheej txheem cov ntsiab lus, tsab xov xwm no qhia txog qhov zoo ntawm LSAW steel kav yog maj mam tsim thaum lub sij hawm tsim khoom.
I. Kev Tswj Xyuas Kev Tswj Xyuas Zoo Pib los ntawm Qhov Chaw
LSAW steel kav siv nruab nrab thiab tuab steel phaj ua raw cov ntaub ntawv, uas inherently txiav txim lawv siv tau rau siab -lub zog thiab siab -siab- bearing tej yam kev mob. Ua ntej nkag mus rau cov txheej txheem tsim khoom, cov hlau phaj tsis yog "siv tau yog tias tsim nyog" tab sis tau txais ntau qhov kev txheeb xyuas.
Ntxiv nrog rau cov pa tshuaj lom neeg muaj pes tsawg leeg thiab kev ntsuas cov cuab yeej cuab tam, tshwj xeeb yog them rau qhov sib xws ntawm cov qauv sab hauv ntawm cov phaj steel. Qhov no yog vim longitudinal submerged arc welded steel kav feem ntau yog siv nyob rau hauv qhov tseem ceeb kis tau tus mob los yog thauj khoom -cov kab nrib pleb. Yog tias cov khoom siv raw muaj qhov tsis xws luag xws li delamination lossis kev suav nrog, txawm tias cov txheej txheem tom ntej vuam tsis tuaj yeem tshem tawm cov kev phom sij ntawm kev nyab xeeb.
Yog li ntawd, kev ntsuam xyuas ultrasonic ntawm cov khoom siv raw khoom tsis yog ib kauj ruam ntxiv tab sis thawj cov kab tseem ceeb ntawm kev tiv thaiv hauv kev tswj xyuas zoo ntawm LSAW steel kav.
II. Qhov cuam tshuam ntawm kev tsim cov txheej txheem ntawm cov yeeb nkab steel kev ua tau zoo
Hauv kev tsim khoom ntawmLSAW steel kav, txoj kev tsim yog ib qho tseem ceeb ntawm kev txiav txim siab qhov tseeb geometric thiab kev ntxhov siab ntawm cov yeeb nkab steel. Txoj kev sib sau JCO tsis ua tiav hauv ib kauj ruam tab sis dhau los ntawm ntau qhov kev ua haujlwm ua tiav.
Qhov kom zoo dua ntawm txoj kev no yog nyob rau hauv kev tswj cov qib ntawm cov yas deformation ntawm cov hlau phaj thaum lub sij hawm tsim, uas ua rau muaj ntau yam kev nyuaj siab faib. Piv nrog rau ib qho - lub sij hawm tsim, kev txhim kho kev ua tau zoo txo qhov kev pheej hmoo ntawm kev ntxhov siab hauv zos thiab muab cov yeeb nkab ruaj khov dua rau cov vuam txuas ntxiv.
Rau qhov ntev - cov haujlwm pabcuam xws li cov kav dej hauv nroog thiab cov kav dej xa hluav taws xob thiab roj, kev ruaj ntseg ntawm lub xeev kev ntxhov siab ntawm cov yeeb nkab steel yog ncaj qha cuam tshuam rau nws lub neej kev pabcuam thiab kev nyab xeeb ntawm kev ua haujlwm.
III. Txoj Kev Sib Raug Zoo Ntawm Pre-welding thiab formal Vuam
Ntau tus tsis yog-cov kws tshaj lij feem ntau yuav saib tsis tau ua ntej- txheej txheem vuam, hais txog nws tsuas yog "kev kho ib ntus." Qhov tseeb, hauv kev tsim cov LSAW steel kav, ua ntej- vuam plays lub luag haujlwm ntawm "kev tswj ua ntej ntawm vuam zoo."
Los ntawm ua ntej- vuam, tej zaum yuav muaj teeb meem xws li kev sib txawv ntawm qhov sib txawv thiab phaj ntug misalignment thaum lub sij hawm tsim tuaj yeem kuaj pom ua ntej. Yog hais tias ncaj qha mus rau sab hauv thiab sab nraud submerged arc vuam, cov teeb meem no feem ntau yog amplified, thiab txawm ua rau irreparable welding tsis xws luag.
Yog li ntawd, kev tshuaj xyuas thiab kho tom qab ua ntej- vuam yog qhov tseem ceeb ua ntej rau kev ua tiav ntawm kev vuam zoo thiab qhov tseem ceeb lav rau qhov sib xws ntawm LSAW steel yeeb nkab welds.
IV. Kev txhim kho ntawm Weld Quality los ntawm Ob -Sided Submerged Arc Vuam
LSAW steel kav siv ob -sided submerged arc vuam txheej txheem sib txuas cov vuam sab hauv thiab sab nraud, uas yog qhov tseem ceeb sib txawv ntawm ib leeg ib leeg- sab vuam.
Submerged arc vuam yog tus cwj pwm los ntawm cov txheej txheem vuam ruaj khov, tswj tau cov cua sov nkag, thiab cov txheej txheem vuam tsis sib xws. Vuam nyob rau hauv cov kev pab them nqi ntawm flux tsis tsuas zoo cais cov huab cua kom txo oxidation txaus ntshai tab sis kuj ho txo qhov tshwm sim ntawm vuam spatter thiab porosity defects.
Ob chav -sab vuam qauv ua rau cov vuam ntau sib luag thaum muaj kev ntxhov siab, thiab tag nrho cov khoom siv kho tshuab muaj kev ntseeg siab dua, uas yog ib qho tseem ceeb vim li cas LSAW steel kav siv tau rau hauv siab - kev ua haujlwm siab.
V. Yog vim li cas tsis yog -Kev sim ua kom puas tsuaj los ntawm tag nrho cov txheej txheem tsim khoom
Hauv cov txheej txheem tsim khoom ntawm LSAW steel kav, tsis yog -kev kuaj kev puas tsuaj (NDT) tsis yog qhov kev tshuaj ntsuam zaum kawg nkaus xwb. Hloov chaw, nws raug xa mus hla ntau theem tseem ceeb ntawm cov txheej txheem tsim khoom. Cov txheej txheem tshuaj xyuas thiab kev sim sib raug yog tsim los ua ntej- vuam, hauv- txheej txheem, thiab tom qab- vuam theem. Lub hom phiaj tsis yog tsuas yog txhawm rau tshuaj xyuas cov khoom tsis yog- ua raws li cov khoom lag luam, tab sis txhawm rau txheeb xyuas cov teeb meem muaj peev xwm nyob rau theem pib, yog li txo cov nqi rov ua haujlwm thiab txo cov kev pheej hmoo zoo.
Kev ntsuam xyuas hluav taws xob feem ntau yog siv los txheeb xyuas qhov tsis xws luag hauv cov vuam, thaum kuaj ultrasonic yog qhov tsim nyog rau qhov loj - ntsuas ntsuas ntawm welds thiab lub hauv paus hlau. Kev sib xyaw ua ke ntawm ntau txoj hauv kev tuaj yeem ua kom muaj txiaj ntsig zoo tshaj plaws ntawm cov chaw muaj peev xwm.
Rau cov haujlwm loj - nplai engineering, ntau- theem kev sim no yog lub hauv paus tseem ceeb rau cov tog neeg los ntseeg LSAW steel kav.
VI. Qhov tseem ceeb ntawm Engineering ntawm Mechanical Expanding thiab Post-Kev kho mob
Tom qab welding tiav, cov kav hlau tsis tuaj yeem nkag mus rau theem khoom tiav. Kev taw qhia txog cov txheej txheem kev nthuav dav ntawm cov neeg kho tshuab feem ntau yog los kho qhov tseeb qhov tseeb ntawm cov yeeb nkab steel thiab txhim kho qhov kev faib tawm ntawm cov vuam seem ntawm kev ntxhov siab.
Los ntawm kev nthuav dav kev kho mob, qhov sib npaug thiab qhov ncaj ntawm cov yeeb nkab steel tuaj yeem ruaj khov dua, uas yog qhov tseem ceeb tshwj xeeb rau tom qab ntawm - qhov chaw teeb tsa. Tshwj xeeb tshaj yog nyob rau hauv ntev - cov kav dej nyob deb, qhov sib xws ncaj qha cuam tshuam rau kev tsim kho thiab vuam zoo.
Cov txheej txheem tom ntej, kev sib tsoo vuam, thiab kev tshuaj xyuas zoo li "pre-siv optimizations" ntawm cov yeeb nkab steel los ntawm kev xaav ntawm daim ntawv thov engineering.
VII. Daim ntawv thov tus nqi ntawm LSAW Steel Pipes los ntawm Kev Pom Zoo ntawm Txheej Txheem Txheej Txheem
Zuag qhia tag nrho, LSAW steel kav tsis yog cov khoom lag luam ntawm ib txheej txheem tab sis ib txoj haujlwm tsim los ntawm ntau cov txheej txheem sophisticated. Lawv qhov zoo yog tsis muaj kev cuam tshuam nyob rau hauv ib qho txuas tab sis nyob rau hauv tag nrho - txheej txheem kev sib koom tes tswj los ntawm kev xaiv cov khoom, tsim, thiab vuam mus rau kev sim.
Raws li qhov no, LSAW steel kav tau dhau los ua ib feem tseem ceeb ntawm kev ua haujlwm ntev - lub sijhawm ruaj khov hauv nroog cov kav dej hauv nroog, kev xa roj thiab roj, kev txuag dej, thiab cov txheej txheem loj -.
Xaus
Nkag siab txog cov txheej txheem tsim khoom ntawm LSAW steel kav yog qhov tseem ceeb rau kev nkag siab txog kev tsim cov logic ntawm kev nyab xeeb thiab ruaj khov. Qhov muaj nyob ntawm txhua tus txheej txheem tsis yog ua kom nyuaj tab sis muab kev lees paub ntau ntxiv rau theem kawg ntawm kev pabcuam.
Nyob rau hauv lub sij hawm ntev - tsom mus rau kev tsim cov longitudinal submerged arc welded steel kav, Huayang Steel Pipe tau txuas ntxiv txhim kho cov txheej txheem tsim khoom thiab kev tswj xyuas kom zoo, tsim kom paub tab thiab ruaj khov LSAW steel yeeb nkab tsim muaj peev xwm los muab cov khoom lag luam txhim khu kev qha rau ntau yam haujlwm engineering.
