Nyob rau hauv cov niaj hnub kev lag luam toj roob hauv pes, infrastructure thiab kev thauj mus los ntawm lub zog sib txuas ua lub hauv paus ntsiab lus ntawm kev loj hlob thoob ntiaj teb kev lag luam. Raws li cov teb xws li kev sib sib zog nqus- dej kev tshawb nrhiav roj, hla- lub teb chaws kis tau tus mob, thiab cov txheej txheem ua haujlwm hnyav txuas ntxiv thawb ciam teb, qhov kev thov rau siab - kev ncaj ncees, loj - txoj kab uas hla piping daws tau nce siab. Ntawm qhov sib txawv ntawm cov welded steel raj muaj hnub no, Longitudinal Submerged Arc Welded (LSAW steel yeeb nkab) sawv tawm raws li qhov kev daws teeb meem zoo tshaj plaws rau qhov xav tau tshaj plaws, ultra-siab- ib puag ncig siab.
Characterized los ntawm nws ncaj longitudinal weld seam, ibLSAW steel yeeb nkabyog tsim los siv hnyav hlau phaj ua raw khoom. Cov phaj no tau dhau los ua txias txias- txheej txheem tsim- xws li JCOE (J-ing, C-ing, O-ing, thiab E-ing) lossis UOE cov txheej txheem tsim-thiab tau txuas ntxiv tom qab los ntawm high-}txoj kev sib koom ua ke (AW) ob npaug rau AW welding -. Cov khoom ua tau nthuav tawm qhov tseeb qhov tsis sib xws, cov phab ntsa tuab, thiab lub zog zoo tshaj plaws.
Raws li ib tug premier thoob ntiaj teb manufacturers,Hebei Huayang Steel Yeeb Nkab Co., Ltd.ua rau saum -tierLSAW steel yeeb nkabcov khoom tsim los tiv thaiv ib puag ncig hnyav, suav nrog kev sib sib zog nqus subsea thiab alpine terrains. Cov lus qhia dav dav no tshawb txog qhov tshwj xeeb tsim kev ncaj ncees, kev ua tau zoo, thiab cov ntawv thov thoob ntiaj teb tseem ceeb ntawmLSAW steel yeeb nkab.
1. Cov txheej txheem tsim khoom Advanced ntawmLSAW steel yeeb nkab
Dab tsi teev covLSAW steel yeeb nkabSib nrug los ntawm lwm cov kav dej welded yog nws qhov tseeb heev, phaj- tsim cov txheej txheem tsim khoom. Tsis zoo li cov kav hlau txuas uas siv cov kav hlau txuas txuas ntxiv, LSAW kev tsim khoom yog nyob ntawm tus kheej, hnyav- ntsuas cov phaj hlau, tso cai rau cov phab ntsa tuab ntau dua.
JCOE LSAW Manufacturing Sequence
Plate Edge Milling -> J-Bending -> C-Bending -> O-Forming -> Tack Weld -> Internal & External Submerged Arc Welding ->Tag Nrho Txias Expansion
JCOE thiab UOE Txoj Kev Ua Haujlwm
Cov phaj hlau nyoos ua ntej dhau qhov siab -siab dej descaling thiab kuaj ultrasonic (UT). Tom qab ntawd nws yog ua tau mus rau hauv lub cylinder. Nyob rau hauv JCOE txoj kev, lub phaj yog khoov kauj ruam - los ntawm - kauj ruam mus rau hauv ib tug 'J' zoo, ces ib tug 'C' puab, ib tug 'O' puab, thiab thaum kawg nthuav ('E') mus calibrate nws lub caij nyoog txoj kab uas hla. Qhov no mechanical txias expansion relieves kev ntxhov siab nyob rau hauv thiab loj heev txhim kho cov yeeb nkab roundness.
Ob -Sided Submerged Arc Vuam (DSAW)
Thaum cov seam tau zoo sib xws, ntau -wire automated welding yog ua. Lub weld yog shielded los ntawm ib tug granular flux uas melts los tsim ib tug tiv thaiv slag daim pam, tiv thaiv tej atmospheric paug. Vuam ob sab hauv thiab sab nraud kom ntseeg tau 100% tag nrho -kev sib koom ua ke ua haujlwm, muab cov seam zoo tib yam kev ua haujlwm rau lub hauv paus steel phaj.
2. Cov khoom tseem ceeb thiab cov cuab yeej zoo
Cov kws tshaj lij qhiaLSAW steel yeeb nkabrau mega- tej yaam num vim nws muaj ob peb lub cev thiab cov yam ntxwv sib txawv uas lwm txoj kev yooj yim tsis sib xws:
Exceptional Phab Ntsa Thickness thiab Loj Diameter
LSAW thev naus laus zis zoo tshaj qhov twg lwm txoj hauv kev ncav cuag lawv qhov txwv. Nws tuaj yeem siv zog ua cov kav dej nrog cov kab sib txuas sab nraud xws li 16 nti txog 60 ntiv tes (thiab loj dua), nrog cov phab ntsa thickness ntau tshaj 50 hli. Qhov no ua rau lawv zoo tagnrho rau qhov sib sib zog nqus- dej thiab siab - cov xwm txheej ntxhov siab.
Superior Ductility thiab Fracture Toughness
Vim hais tias lawv yog fabricated los ntawm siab- nkoj zoo steel daim hlau, cov kav dej no qhia tau hais tias zoo heev plasticity, uniform ductility, thiab superior tsis kam mus tawg propagation. Qhov no resilience yog ib qho tseem ceeb nyob rau hauv cov cheeb tsam uas muaj seismic kev ua si los yog huab cua kub poob.
Unmatched Seam Integrity thiab nruj tolerances
Txoj kev tshaj tawm -weld txias expansion txheej txheem lav tias cov yeeb nkab lub ovality, ncaj, thiab phab ntsa uniformity yog heev meej. Cov yeeb nkab zoo kawg nkaus ua kom yooj yim rau kev sib dhos, ua kom nrawm nrawm ntawm - qhov chaw vuam, thiab txo qis qhov kev ntxhov siab hauv cheeb tsam raws kab.
3. Ua raws li nruj raws li cov qauv kev lag luam thoob ntiaj teb
Txhawm rau ua haujlwm rau lub zog tseem ceeb thiab cov phiaj xwm pej xeem pej xeem, txhuaLSAW steel yeeb nkabyuav tsum nruj me ntsis ua raws li kev soj ntsuam thoob ntiaj teb thiab cov qauv khoom siv.
