ERW Pipes thiab Tubes Manufacturers & Cov neeg muag khoom: Hauv tsab xov xwm no, peb tau hais txog ntau lub ntsiab lus thiab cov ncauj lus kom ntxaws txog nws cov yam ntxwv, hom, kev siv, qhov zoo, thiab nws cov tuam ntxhab thiab cov muag khoom nyiam- "ERW steel kav", "ERW kav dej yog dab tsi", thiab cov txheej txheem tsim cov raj, "yuav ua li cas txheeb xyuas cov kav dej", thiab lwm yam.
ERW daim ntawv puv yog hluav taws xob tsis kam welded. ERW cov kav dej yog tsim los ntawm steel coil thiab weld seam khiav parallel mus rau cov yeeb nkab. Lub coil qhov dav yog coj mus rau tib yam li qhov ncig ntawm cov yeeb nkab yuav tsum tau kho kom cov diameters raug txwv rau qhov siab tshaj plaws ntawm 24 ntiv tes.
ERW Steel Pipe yog dab tsi?
ERW steel kav thiab cov raj yog cov kav dej puag ncig welded los ntawm steel phaj nrog longitudinal welds. Thaum lub sij hawm ERW yeeb nkab vuam txheej txheem, cua sov yog tsim los ntawm tam sim no ntws los ntawm kev sib cuag ntawm qhov chaw vuam. Cov dej ntws tam sim no ua rau ob lub npoo ntawm cov hlau mus rau qhov chaw uas ib ntug tuaj yeem tsim ib daim ntawv cog lus. Yog li ntawd, ob lub npoo ntawm lub raj khoob khoob khoob thiab nyem ua ke nyob rau hauv qhov kev txiav txim ntawm kev sib xyaw ua ke.
Feem ntau, ERW yeeb nkab qhov siab tshaj plaws sab nraud txoj kab uas hla (OD) yog 24 ntiv tes (609mm), thiab rau cov yeeb nkab loj loj yuav raug tsim nyob rau hauv submerged arc welded (SAW).
ERW kav dej feem ntau yog siv los thauj cov pa roj carbon monoxide, roj, thiab lwm yam khoom vapor-kua. Cov yeeb nkab steel no tuaj yeem ua tau raws li qhov xav tau sib txawv ntawm qhov siab thiab qis. Yog li, tam sim no, ERW kav dej tuav txoj haujlwm tseem ceeb hauv kev thauj mus los hauv ntiaj teb.
ERW yeeb nkab yog tsim los siv lub txias HR coils ca steel phaj hloov mus rau hauv ib lub voj voog cylindrical raj. Tom qab nws cov hluav taws xob tam sim no nyob nruab nrab ntawm ob lub npoo ntawm lub phaj hlau dhau los ua kom sov lub phaj hlau mus rau qhov taw tes ntawm kev quab yuam, yuam cov npoo los ua ib qho vuam.
Hluav taws xob tsis kam vuam rau ERW cov kav dej thiab cov raj tsim khoom tuaj yeem muab faib ua cov vuam tsis kam thiab induction vuam. Hauv cov txheej txheem no, hluav taws xob tam sim no yog siv los hloov cov nplaim taws kom sov cov npoo ntawm cov ntawv hlau rau vuam. Lub rotating tooj liab disk yog siv los ua ib qho electrode rau nce qhov kub txog li 2600 degree F rau qhov yuav tsum tau siv vuam zoo.Hluav taws xob tsis kam vuam (ERW)feem ntau yog siv alternating tam sim no nrog ntau zaus ntawm 100 txog 800 kHz, (100.000 txog 800.{5}} cycles ib ob).
Cov txheej txheem ERW yog tus cwj pwm los ntawm ob qho kev cuam tshuam, cov nyhuv ntawm daim tawv nqaij, lossis qhov siab ntawm cov zaus tam sim no ntawm daim ntawv cov npoo npoo, thiab cov nyhuv sib thooj. Cov teebmeem no ua haujlwm thaum lub siab zaus yog tsom rau ntawm ob qhov uas nyob ib sab mus rau sab hauv cov npoo hauv qhov vuam wedge ua ntej qhov vuam taw tes.
Cov teebmeem no txo qis thiab txo cov cua sov tso tawm thaum lub sij hawm siv hluav taws xob vuam txheej txheem. Raws li qhov tshwm sim, cov qauv ntawm cov khoom siv yooj yim hloov pauv hauv thaj chaw me me nyob ib puag ncig fusion kab piv txwv li qhov nruab nrab ntawm qhov vuam. Txhawm rau ua kom tiav cov vuam siv lub tshuab scraping yog siv los tshem tawm cov khoom molten nyob rau sab hauv thiab sab nraud ntawm qhov vuam.
Nta ntawm ERW Yeeb Nkab thiab Tubes
ERW cov kav dej thiab cov raj tsim los ntawm kev siv hluav taws xob ntau zaus tau paub txog cov yam ntxwv zoo thiab cov yam ntxwv zoo li:
Cov khoom siv raw ntawm tsuas yog cov khoom zoo, nruam nruam, tag nrho sedated, tswj dov, nplua-grained qis carbon steel yog siv rau kev tsim cov ERW kav thiab steel hlab.
ERW steel kav thiab raj muaj lub zog siab thiab ua tau zoo dua.
Lawv muaj siab toughness.
Lawv yog ua los ntawm corrosion kuj.
Lawv muaj siab deformability.
Brisk Steel yog ib qho ntawm cov ua lag luam thiab cov chaw muag khoom ntawm ERW cov kav dej thiab cov raj hauv Suav teb, Middle East, thiab lwm lub teb chaws MENA. Peb kuj yog ib qho ntawm cov xa khoom loj tshaj plaws ntawm ERW kav hauv Suav teb.
Hom ERW Pipes Standards
Muaj ntau hom yeeb nkab uas tuaj yeem tsim los ntawm kev siv cov txheej txheem ERW xws li:
ERW Carbon steel yeeb nkab
ERW Stainless hlau yeeb nkab
ERW API Kab yeeb nkab, thiab lwm yam.
Yuav ua li cas txheeb xyuas ERW Stainless Hlau Kav?
Txhawm rau txheeb xyuas seb cov yeeb nkab uas tsim thiab muab rau koj yog ERW, tsuas yog nyeem cov stencil hauv qab no ntawm sab ntawm cov yeeb nkab, piv txwv li:
Yog tias cov stencil yog ASTM A53, hom yeeb nkab no yog S uas txhais tau tias seamless.
Yog tias stencil yog F, hom yeeb nkab no yog lub cub tawg tab sis welded.
Yog hais tias tus stencil yog E, hom yeeb nkab no yog Hluav taws xob tiv thaiv welded (ERW).
Yog li, koj tuaj yeem txheeb xyuas tau yooj yim los ntawm cov txheej txheem saum toj no seb cov yeeb nkab yog seamless lossis ERW.
Dab tsi yog Daim Ntawv Thov thiab Kev Siv ERW Pipes thiab Tubes
ERW cov kav dej thiab cov raj hlau feem ntau yog siv los thauj cov roj thiab cov khoom ua kua xws li roj thiab roj. ERW steel kav yog siv vim tias lawv tuaj yeem ua tau raws li qhov xav tau qis thiab siab siab rau kev nqa roj thiab roj. Raws li kev tsim kho tshiab thiab kev txhim kho hauv ERW thev naus laus zis rau kev tsim cov kav dej thiab cov kav dej zoo dua qub hauv xyoo tas los no, ntau thiab ntau dua ERW steel kav yog siv hauv cov roj thiab roj, kev lag luam tsheb, thiab lwm yam.
Kev siv ERW Steel Pipes thiab Tubes hauv Kev Lag Luam Roj thiab Tshuaj
Txij li qee lub xyoo dhau los, tau muaj kev sib txawv thoob plaws ntiaj teb los hloov cov kav dej seamless steel nrog cov kav dej zoo ERW. Qhov no feem ntau yog vim muaj kev nruam ntej thiab kev txhim kho hauv kev tsim cov thev naus laus zis ntawm welded kav, xws li:
Ua ntej hauvdesulfurization tshuabvim kev tshawb fawb thiab kev loj hlob (RnD) tau txo cov leej faj cov ntsiab lus ntawm cov hlau thiab txhim kho cov vuam zoo ntawm ERW steel kav thiab cov raj.
Kev siv ntawmtshuab nqus tsev degassing tshuabtxhim kho lub purity ntawm lub raj dawb paug strips, txo inclusions, thiab txhim kho cov weld zoo.
Vim yog ntxivcov khoom tshwj xeeb xws li V, Ti, thiab Nb, cov pa roj carbon sib npaug yog txo qis hauv cov ntawv hlau uas ua rau kev txhim kho toughness thiab lub zog ntawm ERW steel kav thiab cov raj.
Txoj kev loj hlob thiab kev taw qhia ntawmkub dov tshuabtau txhim kho cov strips 'dimensional qhov tseeb uas txo qhov seem ntawm qhov sib txawv ntawm ERW cov kav dej thiab cov raj.
Thiab thaum kawg, kev txhim kho hauv kev tshuaj xyuas zoo xws li cov tshuab kuaj hydraulic, kuaj ultrasonic tsis muaj kev puas tsuaj, thiab lwm yam khoom siv tau ua kom zoo ntawm cov khoom kawg, ERW kav, thiab cov raj.
Qhov zoo ntawm ERW Pipes thiab Tubes
Qhov zoo thiab cov txiaj ntsig ntawm ERW steel kav thiab cov raj piv nrog seamless steel kav yog cov hauv qab no:
ERW kav dej muab qhov tseeb dua qhov tseebsuav nrog hauv txoj kab uas hla thiab phab ntsa thickness dua seamless steel kav. Nws yog vim qhov siab qhov tseeb ntawm cov sawb dov thiab cov khoom siv yeeb nkab tswj.
ERW steel kav thiab cov raj muaj cov khoom siv zoo hauv kev sib piv rau seamless steel kav. Nws tseem yog vim ERW cov kav dej muaj qhov ncaj seam hluav taws xob-welded yeeb nkab carbon cov ntsiab lus tsawg dua 12% qis dua cov kav dej seamless thiab cov raj.
ERW steel yeeb nkab nrog siab concentricity, uniform phab ntsa thickness
Tom qab kev kho cua sov, lub microstructure yog sib xws nyob rau hauv ERW kav tshaj nyob rau hauv seamless kav thiab thiaj li tsis tuaj yeem vau.
Kev sim flattening ntawm txoj hlua ncaj nraim ERW steel yeeb nkab yog qhov zoo dua qhov kev sim seamless vim qhov zoo txuas ntawm cov hlau.
ERW steel kav 'kev cuam tshuam toughness yog siab dua li ntawm seamless steel kav.
Longitudinal resistance welded ERW steel kav tsis welded rau cov hlau sib txawv vim yog kev kho cua sov hauv online, thiab yog li cov khoom siv ntawm vuam thiab cov khoom siv yog tib yam.
Tsis muaj fusion hlau siv thaum lub sijhawm tsim khoom ntawm ERW cov kav dej thiab cov raj. Yog li ntawd, cov yeeb nkab yog qhov muaj zog heev thiab ruaj khov.
Qee qhov kev ua yeeb yam ntawm ERW steel kav yog zoo dua li seamless steel kav, thaum nws tus nqi qis dua li ntawm seamless steel kav.
Weld seam ntawm ERW steel kav tsis tuaj yeem pom lossis hnov. Qhov no yog qhov sib txawv tseem ceeb thaum saib cov txheej txheem ob-submerged arc vuam, uas tau tso tseg ib qho kev pom tseeb welded hlaws uas yuav tsum tau muab tshem tawm.
