Txheej txheem cej luam ntawm Basic Concepts
SSAW steel yeeb nkab thiab LSAW steel yeeb nkab ob leeg koom nrog submerged arc welded (SAW) yeeb nkab raug kaw lus, tab sis lawv txawv heev hauv txoj kev tsim, vuam cov txheej txheem, thiab cov txheej txheem tswj kom zoo. SSAW steel yeeb nkab yog tsim los ntawm tsis tu ncua ua steel sawb thiab welding nws raws ib tug kauv lub kaum sab xis, whereas LSAW steel yeeb nkab yog tsim los ntawm ib tug neeg hlau daim hlau tsim thiab welded longitudinally nrog ob -sided submerged arc vuam. Cov kev sib txawv no cuam tshuam tsis tau tsuas yog kev tsim khoom tab sis kuj txiav txim siab lawv qhov tsim nyog rau ntau yam kev siv engineering.
Qhov sib txawv tseem ceeb hauv txoj kev tsim
1. Kauv Forming (SSAW Steel Yeeb Nkab)
SSAW steel yeeb nkab siv kub- dov steel sawb ua raw khoom. Lub sawb txuas ntxiv khoov mus rau hauv cov duab cylindrical tom qab txoj kev muab kauv. Cov yeeb nkab txoj kab uas hla tuaj yeem hloov kho los ntawm kev hloov kho lub kaum sab xis, muab kev hloov pauv siab hauv sizing. Txoj kev tsim no tsim nyog rau kev tsim khoom loj thiab ua haujlwm tas mus li, tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov kav loj -inch, qis- cov kav dej.
2. Ib leeg hlau phaj txoj kev (LSAW steel yeeb nkab)
LSAW steel yeeb nkab yog tsim los ntawm ib tus neeg hlau daim hlau, uas dhau los ntawm ntug milling, ua ntej- dabtsi yog khoov, thiab tsim los tsim kom muaj qhov qhib cylindrical. Cov txheej txheem tsim cov txheej txheem suav nrog UOE thiab JCOE cov txheej txheem, qhov twg lub phaj yog maj mam khoov thiab kaw kom meej kom ntseeg tau tias qhov zoo tshaj plaws roundness thiab ruaj khov qhov ntev. Txoj kev no ua tiav kev tsim cov neeg raug siab dua thiab txhawb nqa kev tswj xyuas nruj.
Qhov sib txawv ntawm Vuam Tshuab
1. Kauv Weld Configuration (SSAW Steel Pipe)
Lub weld seam ntawm SSAW steel yeeb nkab ua raws txoj kev helical raws cov yeeb nkab lub cev thiab yog qhov ntev dua li cov kav dej ntev ntev. Txawm hais tias submerged arc vuam muab kev nkag tau zoo, qhov ntev vuam seam qhia ntau qhov chaw muaj peev xwm tsis xws luag, txwv nws qhov tsim nyog rau siab - kev siv siab.
2. Longitudinal Ob -Sided Vuam (LSAW steel yeeb nkab)
LSAW steel yeeb nkab siv ob sab hauv thiab sab nraud -sab submerged arc vuam. Weld seam yog ncaj, luv, thiab zoo ib yam. Concentrated welding zog ua rau cov vuam tsis sib xws, ua rau nws haum rau siab -siab thiab kev ua haujlwm nyuaj. Qhov luv weld seam kuj tso cai rau kev sim tsis muaj kev puas tsuaj kom ua tau zoo dua thiab ua tau zoo, ua kom ruaj khov thiab tswj tau qhov vuam zoo. Li no, LSAW steel yeeb nkab yog dav nyiam rau siab -kawg engineering tej yaam num.
Qhov sib txawv ntawm Kev Tswj Xyuas Zoo thiab Kev Tshawb Fawb
1. SSAW Steel Yeeb Nkab
Vim qhov ntev thiab helically faib weld seam, txoj kev tshuaj xyuas txuas ntxiv, yuav tsum tau txhim kho kev soj ntsuam tas li thaum tsim khoom. Kev tshuaj ntsuam xyuas cov tshuab siv feem ntau yog siv, tab sis yuav tsum tau ceev faj ntau dua thaum siv SSAW steel yeeb nkab hauv siab -load puag ncig.
2. LSAW Steel Yeeb Nkab
Lub luv luv weld ntawm LSAW steel yeeb nkab tso cai rau kev kuaj hluav taws xob ntau dua, kuaj ultrasonic, thiab kuaj hydrostatic. Nws cov vuam sib xws thiab tag nrho cov khoom sib xws yog siab dua, ua rau nws tsim nyog rau engineering tej yaam num nrog kev ruaj ntseg nruj.

Daim ntawv thov cuam tshuam los ntawm cov txheej txheem sib txawv
1. Daim ntawv thov Scenarios haum rau SSAW Steel Yeeb Nkab
Kev tsim cov peev txheej tas mus li thiab cov txiaj ntsig zoo ua rau SSAW steel yeeb nkab zoo tagnrho rau cov dej hauv nroog, cov kav dej phwj tuaj, thiab cov ntawv thov kev txhawb nqa dav dav. Nws yog tshwj xeeb tshaj yog haum rau loj - txoj kab uas hla pipelines ua hauj lwm nyob rau hauv qis - tej yam kev mob siab.
2. High-End Application Advantages ofLSAW steel yeeb nkab
LSAW steel yeeb nkab muaj kev sib sau ua tau zoo thiab ruaj khov weld zoo, ua rau nws nyiam cov khoom siv rau siab -siab, siab- lub zog, thiab kev siv cov txheej txheem tseem ceeb.
