1. Kev sib piv ntawm cov txheej txheem tsim khoom
1.1. Qhov sib txawv hauv kev tsim cov txheej txheem
Longitudinal submerged arc welded (LSAW) steel kav yog tsim los ntawm ncaj qha shaping steel daim hlau raws lawv qhov ntev. Cov phaj yog ua ntej- khoov, zoo li tus, thiab welded, nrog cov weld seam raws li tib txoj kab ncaj nraim ntawm cov yeeb nkab. Txoj kev no ua kom muaj txoj hauv kev luv luv, kev ntxhov siab tsis sib xws hauv cov phaj steel, thiab qhov tseeb geometric siab. Nyob rau hauv sib piv, kauv welded kav yog tsim los ntawm tsis tu ncua dov steel strips ntawm ib tug tshwj xeeb kauv lub kaum sab xis thiab ces welding lawv. Lub weld seam yog spirally faib nyob ib ncig ntawm cov yeeb nkab nto. Cov txheej txheem no txuas ntxiv tab sis tuaj yeem ua rau muaj qhov sib txawv ntawm cov duab geometric, tshwj xeeb tshaj yog nrog cov kab uas loj dua.
1.2. Qhov txawv ntawm Raw Materials: Steel Phaj vs. Steel Strips
LSAW steel kav feem ntau siv dav, ruaj - dav nruab nrab- tuab steel daim hlau, muab cov khoom ruaj khov thiab cov tuab tuab. Kauv welded kav, ntawm qhov tod tes, yog tsim los ntawm coiled steel strips, uas yuav tsum tau uncoiled, straightened, thiab txiav mus rau qhov loj, ua rau me ntsis variations nyob rau hauv cov khoom sib xws ntawm batches. Yog li ntawd, LSAW steel kav pib nrog cov qib siab dua ntawm qhov sib xws ntawm qhov pib ntawm kev tsim khoom.
2. Qhov sib txawv ntawm cov txheej txheem vuam
2.1. Weld Seam Distribution thiab Energy Input
LSAW steel kav muaj ib los yog ob lub longitudinal weld seam, nrog luv luv weld lengths thiab concentrated zog input, tso cai meej tswj cov txheej txheem vuam thiab weld qauv. Kauv welded kav muaj ntev weld seams, uas faib lub zog tawm tswv yim nyob rau hauv ib cheeb tsam loj, yuav tsum tau ntau dua rau cov cua sov- cuam tshuam cheeb tsam tswj. Qhov ntev ntawm qhov vuam seam, qhov siab dua qhov yuav ua rau muaj qhov tsis xws luag, ua rau LSAW cov kav dej txhim khu kev qha ntau dua ntawm kev vuam zoo.
2.2. Welding Equipment thiab Weld Seam Structure
LSAW steel kav siv sab hauv thiab sab nraud submerged arc vuam rau ib zaug -thov vuam, uas ua kom muaj qib siab ntawm automation thiab zoo sib xws weld nkag. Cov welds feem ntau yog sib sib zog nqus thiab sib sib zog nqus. Nyob rau hauv kev sib piv, thaum muab kauv welded kav kuj siv tau automated submerged arc vuam, lub vuam lub kaum sab xis thiab txoj hauj lwm hloov tsis tu ncua raws li cov seam spirals nyob ib ncig ntawm cov yeeb nkab, uas ua rau me ntsis stability. LSAW cov kav dej muaj kev ntseeg siab dua nyob rau hauv siab - siab, siab - qhov kev ntxhov siab vim qhov sib xws ntawm lawv cov welds.
3. Qhov sib txawv ntawm kev tsim Precision thiab Dimensional Stability
3.1. Geometric Precision
LSAW steel kav yog tsim los siv ntau yam ua ntej- dabtsi yog khoov thiab nias cov menyuam, ua kom muaj txoj hauv kev luv luv uas tso cai rau kev tswj nruj ntawm kev sib tw, ncaj, thiab ntug tiaj tus. Kauv welded kav, txawm li cas los xij, koom nrog cov dov ntawm cov hlau nplaum ntawm cov ces kaum sib txawv, uas tuaj yeem ua rau me ntsis nthwv dej lossis qhov sib txawv ntawm qhov sib txawv. Rau cov kav loj - txoj kab uas hla, qhov kev ua yuam kev nyob rau hauv cov txheej txheem tsim yuav ua kom meej meej nyob rau hauv txoj kev ntev.
3.2. End Quality
Qhov kawg ntawm LSAW kav yog txiav los ntawm cov hlau phaj ua ntej tsim, uas ua rau siab flatness ntawm qhov kawg. Kauv welded kav, tau txuas ntxiv dov, tau nthuav tawm kauv seams tom qab txiav, uas yuav cuam tshuam rau qhov kawg stability. Qhov kawg zoo ncaj qha cuam tshuam qhov ua tau zoo ntawm cov vuam txuas ntxiv, flange kev sib txuas, thiab kev teeb tsa hauv teb.
4. Qhov sib txawv ntawm Cov Txheej Txheem Tsis yog-Kev Ntsuas Kev Ua Phem (NDT).
4.1. Weld Seam Inspection Focus
LSAW steel kav muaj concentrated weld seams, uas tso cai rau kom muaj txiaj ntsig, kev tshuaj xyuas meej xws li kev kuaj kab ultrasonic lossis X-ray tshuaj xyuas, npog tag nrho cov vuam ntau hauv ib zaug. Nyob rau hauv sib piv, cov kauv seams ntawm kauv welded kav yog ntev dua, yuav tsum tau ntau complex thiab ntev soj ntsuam txoj kev. Kev hloov lub kaum sab xis ntawm lub vuam kuj cuam tshuam qhov kev xav thiab attenuation ntawm ultrasonic tsis, ua rau kev sim ntau nyuaj. Yog li ntawd, LSAW steel kav muab ntau ruaj khov zoo tswj thiab txhim khu kev qha soj ntsuam tau.
4.2. Tag Nrho -Size Inspection Coverage
Nyob rau hauv loj - txoj kab uas hla LSAW yeeb nkab ntau lawm, 100% weld seam tsis yog- feem ntau ua rau kev puas tsuaj, thiab qhov chaw soj ntsuam tuaj yeem raug kho kom raug. Thaum cov kav welded kav kuj tau soj ntsuam tag nrho, cov kauv welds qhia ntau qhov sib txawv hauv qhov kev xeem. Rau cov haujlwm uas yuav tsum tau ua kom zoo, txo cov kev pheej hmoo zoo yog qhov tseem ceeb, ua rau cov kav dej LSAW tswj tau ntau dua ntawm cov txiaj ntsig kev sim.
5. Kev sib piv ntawm kev ua tau zoo thiab cov txheej txheem ruaj khov
5.1. Qhov sib txawv ntawm Kev Tsim Nyog Pace
LSAW steel kav yog tsim los ntawm ruaj- ntev steel daim hlau, nrog rau txhua lub phaj sib haum mus rau ib lub yeeb nkab, ua rau muaj kev kwv yees ntau dua thiab zoo ib yam. Kauv welded kav, txawm li cas los xij, yog tsim tawm tsis tu ncua, uas yog tsim nyog rau ntev - nrug, loj - ntim tsim. Txawm li cas los xij, thaum xav tau kev hloov pauv ntau zaus, LSAW steel kav muaj qhov hloov tau yooj yim dua thiab sib xws hauv kev hloov kho tsis tau.
5.2. Txheej Txheem Stability
LSAW steel kav muaj cov ntsiab lus tswj xyuas hauv lawv cov txheej txheem tsim thiab vuam, ua rau cov txheej txheem ntau dua. Nyob rau hauv sib piv, kauv welded kav, nrog lawv cov nruam dov txoj kev, tej zaum yuav muaj kev hloov nyob rau hauv steel sawb nro thiab lub kaum sab xis hloov, uas yuav cuam tshuam rau txoj kev zoo. Rau siab -xav tau tej yaam num, txheej txheem stability yog ib qho tseem ceeb xav txog.
6. Cov txheej txheem tsim khoom tau txais txiaj ntsig los ntawm kev thov kev thov
6.1. Kev tsim khoom yuav tsum muaj rau siab -Txoj Kev Kub Siab
LSAW steel kav zoo dua rau siab - siab, siab - kev ntxhov siab, thiab ntev - cov kav dej sib txuas, xws li cov siv hauv cov roj thiab cov roj xa hluav taws xob, ua tsaug rau lawv cov weld ncaj seams, muaj zog vuam zog, thiab cov qauv vuam tsis sib xws. Kauv welded kav, vim lawv ntev weld seams, kuj tsis tshua muaj kev ntseeg siab nyob rau hauv huab cua siab.
