Taw qhia
Nrog txoj kev loj hlob sai ntawm lub ntiaj teb kev tsim hluav taws xob, kev thauj mus los hauv dej, thiab cov haujlwm ua haujlwm sab nrauv, qhov kev thov loj - txoj kab uas hla, siab - lub zog, thiab ntev - lub neej kav dej txuas ntxiv mus ntxiv. Ntawm tag nrho cov yeeb nkab steel tsim thev naus laus zis, LSAW steel yeeb nkab tau dhau los ua ib qho ntawm cov kev siv dav dav tshaj plaws rau cov kav xa mus ntev - deb, siab - cov tshuab siab, thiab hnyav - thauj khoom engineering.
LSAW steel kav yog tsim los siv longitudinal submerged arc vuam tshuab thiab paub txog lawv qhov zoo ntawm qhov raug, muaj zog txhua yam khoom, ruaj khov weld zoo, thiab zoo siab ua haujlwm. Cov yam ntxwv no ua rau LSAW cov kav dej yog qhov kev xaiv zoo tshaj plaws rau cov kav dej roj thiab roj, hla - cov kav dej hauv lub tebchaws, cov chaw tawm sab nraud, cov kav hlau txuas, thiab loj - cov chaw hauv nroog loj.
Kab lus no qhia txog cov kev siv engineering, cov yam ntxwv ntawm kev ua haujlwm, kev ua haujlwm zoo, thiab kev ua haujlwm ntev -lub sij hawm kev pabcuam zoo ntawm LSAW steel kav los ntawm kev xav txog engineering.
Cov yam ntxwv ntawm LSAW Steel Pipes
LSAW steel kav yog tsim los ntawm cov hlau hnyav los ntawm kev sib sau, qhov ntev vuam, thiab tom qab- cov txheej txheem txuas ntxiv. Tsis zoo li cov kav dej los yog cov kav dej seamless, LSAW cov kav dej muaj cov kab ncaj nraim ntawm cov kav dej sib txuas khiav raws cov yeeb nkab axis.
Txoj kev tsim khoom no muab ob peb yam tseem ceeb ntawm cov qauv zoo:
Cov yeeb nkab phab ntsa tuab tuaj yeem tswj tau qhov tseeb
Cov yeeb nkab txoj kab uas hla tuaj yeem hloov kho rau cov haujlwm loj -
Weld seam yog ib qho yooj yim los soj ntsuam thiab tswj xyuas
Cov yeeb nkab geometry tseem ruaj khov heev
Lub roundness thiab straightness yog superior
Tom qab vuam, cov yeeb nkab tau dhau los ua kev nthuav dav los txhim kho qhov tseeb qhov tseeb thiab txo qis kev ntxhov siab. Qhov no ua rau zoo heev roundness thiab zoo ib yam phab ntsa thickness raws tag nrho cov yeeb nkab ntev.
Mechanical Performance thiab Load Capacity
Lub zog ua haujlwm
LSAW steel kav feem ntau yog tsim los siv cov qib carbon steel xws li API 5L X52, X60, X65, X70, thiab X80. Cov hlau no muab lub zog tawm los siab, lub zog tensile zoo, thiab ruaj khov elongation zog.
Lub longitudinal weld seam yog tsim los siv ntau -wire submerged arc vuam, uas ua kom muaj kev nkag mus tob thiab cov qauv hlau tsis sib xws. Tom qab welding, lub seam yog raug rau kev kuaj ultrasonic thiab radiographic tshuaj xyuas, kom ntseeg tau tias lub zog weld ntsib los yog tshaj lub hauv paus hlau zog.
Kev ua tau zoo txhua yam muaj xws li:
High yield -rau-tensile ratio
Muaj zog tiv thaiv cov yas deformation
Kev ua haujlwm ruaj khov nyob rau hauv cyclic loading
Zoo heev tawg toughness
Fatigue Resistance
Hauv ntev - cov kav dej nyob deb thiab cov qauv hauv ntug dej hiav txwv, cov kav dej tau raug cuam tshuam los ntawm kev hloov pauv ntawm kev hloov pauv, qhov kub thiab txias hloov, thiab cov khoom ib puag ncig sab nraud. LSAW kav dej muaj kev qaug zog zoo heev vim lawv cov qauv microstructure thiab tsis tshua muaj kev ntxhov siab tom qab nthuav dav.
Lub longitudinal weld seam orientation txo cov kev ntxhov siab piv rau cov kauv welds, uas pab txo qis qaug zog tawg pib thaum lub sijhawm ua haujlwm ntev -.
Kev ua haujlwm siab thiab sealing kev ntseeg tau
Ib qho ntawm cov kev xav tau tseem ceeb tshaj plaws rau cov kav raj xa dej yog lub zog sab hauv. LSAW steel kav yog tsim los rau siab - kev pabcuam siab thiab tau siv dav hauv kev xa cov roj av, cov kav dej roj av, thiab kev thauj mus los hauv dej siab - siab.
Cov qauv phab ntsa tuab thiab cov duab geometry tso cai rau cov kav dej LSAW tuaj yeem tiv taus siab hauv siab. Kev ntsuam xyuas hydrostatic ua kom ntseeg tau tias txhua cov yeeb nkab ua tau raws li qhov ntsuas kev nyab xeeb ntawm cov txheej txheem thoob ntiaj teb.
Cov yam ntxwv ntawm kev ua haujlwm siab muaj xws li:
High tawg siab ntsuas
Zoo sealing kev ncaj ncees
Tsawg deformation nyob rau hauv siab
ruaj khov ntev -lub sij hawm siab endurance
Cov yam ntxwv no ua rau cov kav dej LSAW zoo tagnrho rau kev hla -cov kav xa hluav taws xob hauv lub tebchaws thiab cov kav dej hauv qab hiav txwv.
Corrosion Resistance thiab Txheej Compatibility
Cov kav raj xa dej feem ntau raug cuam tshuam rau ib puag ncig hnyav xws li av noo, dej hiav txwv, tshuaj lom neeg, thiab muaj kuab lom. LSAW cov kav dej tau ua tiav nrog ntau yam kev tiv thaiv corrosion.
Cov txheej txheem txheej txheem muaj xws li:
3LPE thiab 3LPP txheej txheej sab nraud
Fusion bonded epoxy txheej
Internal epoxy txheej
Qhob hnyav txheej rau offshore pipelines
Thermal rwb thaiv tsev txheej
Cov yeeb nkab du nto thiab niaj hnub weld profile muab qhov zoo tshaj plaws substrate rau txheej adhesion. Qhov no ua kom ntev -lub sij hawm corrosion kuj thiab txuas mus rau lub kav dej ua haujlwm.
