Nyob rau hauv lub steel yeeb nkab manufacturing teb, ob lug siv longitudinal welded yeeb nkab hom pab distinctly engineering xav tau kev pab: ERW steel yeeb nkab thiabLSAW steel yeeb nkab. Txawm hais tias ob qho tib si yog longitudinal welded cov khoom, lawv cov txheej txheem tsim txawv kiag li, uas ua rau muaj kev hloov pauv tseem ceeb hauv cov khoom lag luam, cov ntawv thov scenarios, thiab cov txheej txheem tswj kom zoo. Cov ntu hauv qab no muab kev tshuaj xyuas zoo los ntawm qhov kev xav ntawm cov txheej txheem ntws, cov txheej txheem vuam, cov khoom siv, thiab kev ua haujlwm zoo.
1. Qhov sib txawv ntawm kev xaiv raw khoom thiab kev npaj uncoiling
1.1. Variations nyob rau hauv Raw Material Specifications
ERW steel yeeb nkab feem ntau siv nruab nrab thiab nyias - ntsuas steel coils raws li cov khoom siv raw, ua rau nws tsim nyog los tsim cov kav dej me me mus rau nruab nrab. Lub zog thiab tuab ntawm cov kauj yog nruab nrab, ua kom nrawm nrawm los ntawm kev siab - zaus vuam.
LSAW steel yeeb nkab siv ntau daim hlau tuab, feem ntau yog daim hlau dav lossis daim hlau hnyav. Cov phaj no dhau los ua ntej- khoov thiab sib sau los ntawm cov khoom siv loj loj. Raws li LSAW cov kav dej yog npaj rau siab - lub zog thiab siab - cov ntawv siv siab, cov phaj hlau feem ntau yog ua los ntawm qib siab - cov ntaub ntawv metallurgical qib thiab yuav tsum dhau kev soj ntsuam nruj.
1.2. Txawv Uncoiling thiab Leveling Methods
ERW steel yeeb nkab siv siab -ceev, tsis tu ncua uncoiling thiab leveling cov cuab yeej, uas qhia txog kev ua haujlwm zoo thiab ua haujlwm zoo. Tom qab leveling, steel sawb nkag mus rau hauv lub tshuab tsim ncaj qha thiab yog zoo li tus mus rau hauv ib puag ncig raj los ntawm nruam yob txoj kev.
LSAW steel yeeb nkab yuav tsum muaj txheej txheem kev sib tw ntau dua, suav nrog cov khoom siv siab - tonnage leveling kom ntseeg tau tias cov phaj ncaj ncaj thiab qhov chaw tiaj tus rau cov vuam tom ntej. Vim tias cov phaj tuab dua, cov khoom siv thauj khoom ntau dua thiab cov khoom lag luam qeeb qeeb.
2. Cov qauv sib txawv ntawm txoj kev tsim
2.1. Roll-Txoj Kev Ua Haujlwm ntawmERW steel yeeb nkab
ERW steel yeeb nkab tau txais kev sib txuas txuas ntxiv, qhov twg cov txheej txheem yob maj mam curl cov hlau sawb rau hauv ib puag ncig lossis ze rau - puag ncig. Cov txheej txheem no yog du thiab nrawm, ua rau nws zoo tagnrho rau kev tsim khoom loj.
Qhov zoo muaj xws li: • High forming speed • High efficiency efficiency • Zoo dimensional uniformity
Txawm li cas los xij, vim yog cov ntaub ntawv nyias nyias, kev tsim kev ruaj ntseg yog qhov nkag siab ntau dua rau cov sawb lub zog thiab tuab.
2.2. Khoov-Forming Method ofLSAW steel yeeb nkab
LSAW steel yeeb nkab siv U-O lossis UOE txheej txheem. Lub phaj steel yog thawj zaug ua ntej- khoov los tsim curvature, tom qab ntawd khoov rau hauv U-puab thiab O-puab los ntawm cov khoom siv los tsim cov yeeb nkab puag ncig.
Txoj kev tsim no muaj: • Muaj peev xwm loj - txoj kab uas hla thiab tuab - cov kav dej hauv phab ntsa • Kev ua haujlwm siab raug • Kev tsim nyog rau qhov hnyav - lub luag haujlwm engineering xav tau
Txawm hais tias qeeb qeeb thiab raug nqi ntau dua, cov kav dej uas ua rau muaj kev ncaj ncees ntau dua.
3. Qhov txawv ntawm qhov sib txawv hauv cov txheej txheem vuam
3.1. ERW Steel Yeeb Nkab Siv Siab -Vuam Tsis Zoo
Siab- zaus vuam tsim cov nyhuv ntawm daim tawv nqaij thiab qhov sib thooj ntawm qhov sib koom ua ke, cua sov sai sai thiab yaj cov npoo, uas tom qab ntawd sib xyaw ua ke los ntawm kev sib tsoo.
Cov yam ntxwv tseem ceeb muaj xws li: • Tsis tshua muaj cua sov input • Fast weld tsim • Tsis tshua muaj vuam efficiency • Tsis muaj hlau muab tub lim
Thaum siv tau rau nyias- thiab nruab nrab- cov kav dej hauv phab ntsa, cov txheej txheem tsis muaj cov cua sov txaus rau cov tuab- cov ntawv siv phab ntsa thiab siab - qhov chaw siab.

LSAW steel yeeb nkab txais yuav sab hauv thiab sab nraud submerged arc vuam, qhov chaw muab tub lim, flux, thiab siab vuam tam sim no tsim qhov sib sib zog nqus welds.
Qhov zoo muaj xws li:• sib sib zog nqus weld nkag mus • Txaus weld hlau filling• ntom thiab zoo weld microstructure• Compatibility nrog tuab -phab ntsa thiab siab- qib steels
Cov txiaj ntsig welds tiv taus siab sab hauv thiab sab nraud cuam tshuam, ua rau txoj kev tsim nyog rau kev thov kev siv engineering.
4. Qhov sib txawv ntawm Weld Quality Control Processes
4.1. Kev tshuaj xyuas online rau ERW Vuam
ERW steel yeeb nkab feem ntau siv online eddy-tam sim no lossis ultrasonic kuaj los saib xyuas qhov txuas txuas ntxiv thiab kuaj pom qhov chaw- theem tsis xws luag. Thaum ua tau zoo, qhov txwv weld qhov tob nce rhiab heev rau cov khoom siv raw zoo thiab cov txheej txheem ruaj khov.
4.2. Kev soj ntsuam xyuas rau LSAW Vuam
LSAW steel yeeb nkab tau txais kev tshuaj xyuas dav dav, suav nrog kev ntsuam xyuas sab hauv thiab sab nraud, kev tshuaj xyuas ultrasonic, X- kev ntsuas hluav taws xob, thiab kev ntsuas siab.
Cov kev ntsuam xyuas muaj xws li: • Kev kuaj tag nrho weld ultrasonic • X- kev soj ntsuam kab hluav taws xob • Hydrostatic testing • Metallographic thiab mechanical property sampling
Cov kev tshuaj xyuas no npog tag nrho cov tuab tuab, ua kom cov yeeb nkab ua tau raws qhov siab - xav tau kev tsim vaj tsev.
5. Qhov txawv hauv Post-Kev ua tiav
5.1. Common Post-Kev ua haujlwm rau ERW Steel Pipe
Feem ntau yog siv nyob rau hauv nruab nrab mus rau qis siab los yog cov qauv siv, ERW steel yeeb nkab yuav tsum tau yooj yim tshaj ncej- ua, xws li:• Ncaj• Txiav• tiv thaiv coatings los yog los tiv thaiv- kev kho corrosion• Basic dimensional soj ntsuam
Cov kauj ruam no txaus rau kev tsim kho, tshuab, thiab kev xav tau kev thauj mus los.
5.2. Hnyav-Lub luag haujlwm Post-Kev ua haujlwm rau LSAW Steel Pipe
LSAW steel yeeb nkab yuav tsum tau nthuav dav ntau dua - kev ua haujlwm, suav nrog: • Hnyav - lub luag haujlwm roundness kho • Sab hauv thiab sab nraud vuam sib tsoo • Txheej lossis tiv thaiv- txheej txheej corrosion • Cov ntim ntim tau ntev - thauj mus los
Cov txheej txheem ntxiv no txhim kho lub peev xwm siab thiab kev ruaj ntseg.
6. Daim ntawv thov kev ua tau zoo sib txawv uas tau tsav los ntawm cov txheej txheem Variations
6.1. ERW Steel Yeeb Nkab yog tsim rau nruab nrab mus rau qis siab
