Hauv kev tsim cov yeeb nkab steel niaj hnub no, cov txheej txheem vuam sib txawv tau txais los ua kom tau raws li ntau yam kev xav tau ntawm engineering, cov qauv kev ua haujlwm, thiab kev siv ib puag ncig. Ntawm cov feem ntau siv welded yeeb nkab hom, ERW, LSAW, thiab HSAW kav sawv cev rau peb loj ntau lawm technologies. Txhua tus txheej txheem tsim cov kav dej nrog cov yam ntxwv tshwj xeeb, qhov zoo, thiab cov ntawv thov tsim nyog. Raws li cov chaw tsim khoom ntawm welded steel kav, Huayang Steel Pipe siv cov txheej txheem siab tshaj plaws thiab vuam thev naus laus zis kom xa cov khoom zoo tshaj plaws rau cov haujlwm hauv tsev thiab thoob ntiaj teb.
Hauv qab no yog cov lus piav qhia meej thiab cov qauv ntawm qhov sib txawv ntawm ERW, LSAW, thiab HSAW kav.
1. ERW / HFW Pipes
ERW stands rau Electric Resistance Vuam, tseem hu ua High Frequency Vuam. Cov txheej txheem no siv cov kev tiv thaiv uas tsim los ntawm siab - zaus tam sim no los ua kom sov cov npoo ntawm cov hlau sawb, uas tom qab ntawd nias ua ke los ua ib qho kev sib koom ua ke. ERW kav dej muaj longitudinal weld seams thiab raug tsim tsis siv cov hlau muab tub lim.
Cov yam ntxwv tseem ceeb ntawm ERW Pipes
• Ncaj longitudinal weld seam
• Cov cua sov me me heev- thaj tsam cuam tshuam vim yog siab - vuam zaus
• Smooth puab thiab sab weld zoo li
• Feem ntau siv rau cov kav dej me me mus rau nruab nrab
• Ntau lawm ceev thiab ruaj khov zoo sib xws
Thaum lub sij hawm tsim khoom, coils yog unrolled, flattened, tsim rau hauv cylindrical duab, thiab welded ntawm kev kub ceev. Kev tsim khoom ntawm ERW cov kav dej tuaj yeem ncav cuag li 12 meters ib feeb, ua rau nws muaj txiaj ntsig zoo rau kev tsim khoom loj.
Vim tias cov kav dej ERW tsis siv cov khoom siv muab tub lim thiab muaj qhov ua tau zoo ntawm qhov ntev, lawv tau siv dav hauv cov kav dej qis mus rau nruab nrab, kev siv cov txheej txheem, cov khoom siv dej, thiab cov tshuab raj.
2. LSAW Pipes
LSAW sawv cev rau Longitudinal Submerged Arc Vuam. Txoj kev no pib nrog kev txiav steel phaj rau hauv qhov dav dav, uas tom qab ntawd ua rau cov yeeb nkab duab siv ntau yam xovxwm- txheej txheem tsim. Thaum tsim, ob sab ntawm lub seam tau koom nrog thiab welded longitudinally siv submerged arc vuam.
Cov yam ntxwv tseem ceeb ntawm LSAW Pipes
• Ncaj thiab zoo ib yam longitudinal weld seam
• Welded siv cov hlau muab tub lim thiab submerged arc vuam tshuab
• Cov cua sov me me- thaj tsam cuam tshuam, zoo ib yam li ERW
• Haum rau txoj kab uas hla loj, tuab- phab ntsa, thiab siab - cov kav dej muaj zog
• Zoo heev mechanical zog thiab weld kev ncaj ncees
LSAW yeeb nkab ntau lawm ceev yog feem ntau nyob ib ncig ntawm 4 meters ib feeb, qeeb dua ERW vim muaj ntau txoj kev sib sau thiab vuam cov kauj ruam. Txawm li cas los xij, LSAW kav dej muaj kev nkag tau zoo tshaj plaws ntawm kev sib txuas, kev ua haujlwm ruaj khov, thiab kev tswj xyuas nruj, ua rau lawv tsim nyog rau cov ntawv thov uas xav tau kev ntseeg siab.
LSAW kav yog feem ntau siv nyob rau hauv ntev - cov roj thiab roj kav, onshore thiab offshore engineering, piling foundations, structural steel kem, thiab lwm yam kev siv tseem ceeb.
3. HSAW Pipes
HSAW stands rau Helical Submerged Arc Vuam, tseem hu ua SSAW (Spiral Submerged Arc Vuam). Nyob rau hauv cov txheej txheem no, steel coils yog spirally tsim rau hauv cylindrical kav, thiab cov npoo yog welded siv submerged arc vuam.
Cov yam ntxwv tseem ceeb ntawm HSAW Pipes
• Kauv vuam seam raws lub cev ntawm cov yeeb nkab
• Siv cov hlau muab tub lim nrog ob -sided submerged arc vuam
• Cov cua sov loj dua- thaj tsam cuam tshuam vim yog kev sib tw welding
• Ntau lawm yooj yooj yim nrog adjustable diameters
• Weld seam ntev yog 1.5 mus rau 2 npaug ntawm cov yeeb nkab ntev
HSAW yeeb nkab ntau lawm ceev yog feem ntau nyob ib ncig ntawm 2 meters ib feeb thiab yog qeeb dua ERW thiab LSAW. Txawm li cas los xij, nws muaj peev xwm tsim cov kav loj - txoj kab uas hla siv nqaim - dav hlau kauj ua rau nws raug nqi - siv tau rau qee yam kev siv.
HSAW cov kav dej feem ntau yog siv rau cov kav dej, piling, kev txhawb nqa, thiab qis - mus rau - nruab nrab cov tsheb thauj mus los.
Cov ntsiab lus sib piv
Yuav kom nkag siab zoo dua qhov sib txawv ntawm peb cov txheej txheem, hauv qab no yog qhov sib piv sib piv:
Vuam Technology

• LSAW: Kwv yees li 4 m/min
• HSAW: Kwv yees li 2 m/min
Weld Seam Ntev
• ERW thiab LSAW: Ncaj, tib yam li cov yeeb nkab ntev
• HSAW: Kauv seam 1.5–2 zaug yeeb nkab ntev
Daim Ntawv Thov Scope
• ERW: Nruab nrab txoj kab uas hla, qis mus rau nruab nrab siab cov kav dej
• LSAW: Loj txoj kab uas hla, tuab-phab ntsa, siab-siab lossis ntev- cov kav xa dej
• HSAW: Txoj kab uas hla loj, siab mus rau nruab nrab, cov txheej txheem pawg, cov kav dej
Xaus
ERW, LSAW, thiab HSAW steel kav txhua tus ua haujlwm sib txawv hauv ntau qhov kev lag luam. ERW kav dej muab qhov zoo tshaj plaws qhov tseeb thiab ua tau zoo. LSAW cov kav dej kom ntseeg tau zoo tshaj qhov zoo thiab tau siv dav hauv kev xav tau cov kav dej. HSAW cov kav dej muaj nqi zoo thiab yooj yim hauv - txoj kab uas hla ntau lawm.
Nrog cov cuab yeej tsim khoom siab heev thiab kev tswj xyuas nruj, Huayang Steel Pipe muab tag nrho peb hom welded kav kom tau raws li qhov xav tau ntawm cov neeg siv khoom hauv tsev thiab thoob ntiaj teb. Txawm hais tias kev thauj mus los ntawm cov roj thiab roj, cov khoom siv dej, kev tsim vaj tsev, lossis kev siv sab nrauv, xaiv cov txheej txheem vuam tsim nyog ua kom muaj kev nyab xeeb, kav ntev, thiab ua haujlwm ntev -.
