ERW kav dej yog tsim los siv kub- dov steel coils uas tsim thiab welded longitudinally los ntawm siab - zaus kuj welding. Vim tias cov txheej txheem vuam tsis cuam tshuam nrog cov khoom siv hlau, cov khoom siv hauv paus ua lub luag haujlwm txiav txim siab txog qhov kawg ntawm cov khoom siv ntawm cov yeeb nkab.
Cov qib sib txawv raug xaiv nyob ntawm qib siab, cov qauv thauj khoom, thiab ib puag ncig ntawm daim ntawv thov. Cov qib qis zog xws li Q235B lossis ASTM A53 Gr.B feem ntau yog siv rau hauv kev tsim kho thiab cov kav dej hauv nroog uas yuav tsum muaj lub zog nruab nrab thiab zoo weldability. Lub zog siab dua qib siab xws li API 5L X52 lossis X70 yog tsim los rau lub zog tsheb thauj mus los uas ua haujlwm nyob rau hauv siab dua thiab nruj dua cov qauv kev nyab xeeb.
Txoj kev loj hlob ntawm cov txheej txheem steel qib tso cai rau cov tuam txhab thiab cov kws tsim khoom xaiv cov khoom siv nrog cov khoom siv dag zog thiab cov tshuaj lom neeg muaj pes tsawg leeg. Qhov no ua kom ntseeg tau tias cov kav dej uas tsim nyob rau hauv cov cheeb tsam sib txawv lossis los ntawm cov tuam txhab sib txawv tuaj yeem ua tau raws li qhov xav tau ntawm engineering tib yam.
ASTM thiab API Steel Qib hauv ERW Pipe Production
ASTM A53 Gr.B thiab API 5L Qib
| Qib | Yield zog (MPa) | Tensile zog (MPa) | Kev lag luam ib txwm siv |
|---|---|---|---|
| ASTM A53 Gr.B | Ntau dua lossis sib npaug li 240 | Ntau dua lossis sib npaug rau 415 | Kev tsim vaj tsev, cov kav dej |
| API 5L Gr.B | Ntau dua lossis sib npaug li 245 | Ntau dua lossis sib npaug rau 415 | Roj thiab roj sib sau ua ke kab |

| API 5L X70 | Ntau dua lossis sib npaug rau 485 | Ntau dua lossis sib npaug li 570 | Ntev - kis tau tus mob kav |
ASTM A53 Qib B yog ib qho ntawm cov qib carbon steel feem ntau siv rau ERW cov kav dej hauv kev siv dav dav. Nws yog tsim los rau kev siv tshuab thiab siab nrog rau kev siv tib yam hauv chav dej, dej, roj, thiab cov kav dej. Cov qib muab qhov sib npaug ntawm qhov sib npaug ntawm lub zog thiab kev ua kom zoo thaum tuav cov weldability zoo, uas yog qhov tseem ceeb rau kev tsim khoom ntawm ERW.
API 5L Qib B feem ntau yog siv rau hauv kev lag luam roj av thiab cov pa roj carbon monoxide rau cov kav xa dej. Txawm hais tias nws cov khoom siv kho tshuab zoo ib yam li ASTM A53 Gr.B, API 5L ua kom nruj dua cov kev cai ntawm cov tshuaj muaj pes tsawg leeg, cuam tshuam rau cov tawv nqaij, thiab cov txheej txheem tshuaj xyuas. Cov kev xav tau ntxiv no ua kom ntseeg tau tias cov kav dej tuaj yeem ua haujlwm ruaj ntseg hauv cov khoom siv hluav taws xob uas nyob hauv qhov siab thiab ib puag ncig yuav hloov pauv.
Cov qib siab zog kav dej xws li X42, X52, X60, thiab X70 tau tsim los txhim kho kev ua tau zoo ntawm cov kav dej ntev - deb. Raws li cov txiaj ntsig muaj zog nce ntxiv, cov neeg tsim cov kav dej tuaj yeem txo cov phab ntsa tuab thaum tuav lub peev xwm tib yam. Qhov no ua rau txo qis kev siv cov khoom siv thiab txhim kho kev lag luam zoo rau - cov phiaj xwm loj loj.
Txawm li cas los xij, qib siab zog yuav tsum nruj dua tswj cov tshuaj muaj pes tsawg leeg thiab kev tsim khoom. Cov pa roj carbon sib npaug yuav tsum nyob twj ywm nyob rau hauv ib qho kev sib tw kom tswj tau qhov weldability, thiab kev tshuaj xyuas ntxiv xws li kev kuaj ultrasonic feem ntau yuav tsum tau ua kom ntseeg tau tias weld seam kev ncaj ncees.
Suav Structural Steel Qib rau ERW Pipes
Suav cov qauv kuj txhais tau ntau yam siv cov pa roj carbon steel qib rau ERW yeeb nkab ntau lawm, tshwj xeeb tshaj yog nyob rau hauv cov qauv thiab hauv nroog engineering daim ntaub ntawv. Ntawm cov qib no, Q235B thiab Q355B yog cov khoom siv nquag siv hauv Suav teb steel yeeb nkab kev lag luam.
Q235B yog suav hais tias yog cov qauv carbon steel qib. Nws muaj cov yas zoo, lub zog nruab nrab, thiab kev ua haujlwm zoo heev, ua rau nws tsim nyog rau kev tsim kho scaffolding, lub hauv paus hauv paus, thiab cov kav dej hauv nroog. Vim hais tias cov khoom muaj cov ntsiab lus qis carbon, nws nthuav tawm ruaj khov weldability thaum lub sij hawm ERW ntau lawm txheej txheem.
Q355B sawv cev rau qib siab zog ntawm cov qauv hlau uas tau siv dav hauv cov qauv kev tsim vaj tsev uas xav tau ntau dua cov load-cov kabmob muaj peev xwm. Piv nrog Q235B, Q355B muab cov txiaj ntsig zoo dua qub thaum tseem tuav tau zoo toughness thiab vuam yam ntxwv. Qhov no ua rau nws tsim nyog rau cov tswv cuab hnyav, cov khoom siv txuas ntxiv, thiab cov phiaj xwm loj -.
Hauv ntau qhov chaw tsim khoom ERW yeeb nkab, cov qib no tau ua tiav siv cov txheej txheem siab heev thiab cov kab vuam uas muaj peev xwm tswj xyuas qhov ntsuas qhov tseeb thiab cov khoom siv zoo ib yam. Cov hlau coils raug tshuaj xyuas ua ntej tsim, thiab cov kav dej zaum kawg tau kuaj xyuas cov khoom siv thiab tsis yog -kev tshuaj ntsuam xyuas kom ntseeg tau tias lawv ua raws li cov qauv xav tau.
Kev xaiv cov khoom siv rau kev siv engineering sib txawv
Xaiv cov qib steel tsim nyog yog ib kauj ruam tseem ceeb hauv kev tsim cov kav dej thiab kev tsim kho. Cov kws kho tsheb yuav tsum xav txog ntau yam xws li kev siab sab hauv, kev thauj khoom sab nraud, ib puag ncig ib puag ncig, thiab ntev -kev pheej hmoo corrosion.
Rau cov kav dej hauv nroog thiab cov kav dej tiv thaiv hluav taws, cov qib xws li ASTM A53 Gr.B lossis Q235B feem ntau txaus vim tias qhov kev khiav hauj lwm siab tsawg thiab qhov tseem ceeb yuav tsum tau muaj yog kev ntseeg siab thiab yooj yim ntawm installation. Cov qhab nia no muaj qhov zoo weldability thiab muaj zog txaus rau cov phiaj xwm hauv nroog.
Hauv cov roj thiab roj sib sau ua ke lossis nruab nrab - cov kav dej sib kis, API 5L Qib B lossis X42 kav feem ntau xaiv. Cov qib no muab lub zog siab dua thiab nruj dua cov qauv tswj kev ua tau zoo, kom ntseeg tau tias cov kav dej tuaj yeem ua haujlwm zoo nyob rau hauv cov xwm txheej hloov pauv.
Rau qhov ntev - lub zog xa hluav taws xob nyob deb, cov qib siab zog xws li X60 lossis X70 tuaj yeem siv. Cov ntaub ntawv no tso cai rau cov engineers tsim cov kav dej nrog cov phab ntsa nyias nyias thaum tuav lub peev xwm siab, uas txo qis tag nrho qhov hnyav ntawm cov hlau xav tau rau cov haujlwm loj.
Lub luag haujlwm ntawm Cov Qauv Khoom Siv hauv ERW Pipe Manufacturing
Lub hav zoov ntawm cov qib steel tau lees paub thoob ntiaj teb ua kom muaj kev sib xws hauv ERW yeeb nkab ntau lawm thoob ntiaj teb kev lag luam. Cov txheej txheem txhais tsis tau tsuas yog cov khoom siv kho tshuab xwb tab sis kuj muaj cov tshuaj lom neeg muaj pes tsawg leeg, kev kho cua sov, thiab cov txheej txheem tshuaj xyuas. Lub moj khaum no tso cai rau cov chaw tsim khoom siv yeeb nkab los tsim cov ntaub ntawv uas ua tau raws li cov kev qhia tshwj xeeb ntawm kev lag luam sib txawv.
Niaj hnub nimno ERW cov kab ntau lawm ua ke nrog kev siv vuam thev naus laus zis, kev tshuaj xyuas online, thiab cov txheej txheem tswj xyuas nruj. Los ntawm kev sib txuas cov kev tswj xyuas qhov tseeb nrog cov qib steel qauv, cov tuam txhab tsim khoom tuaj yeem tsim cov kav dej tsim nyog rau ntau qhov chaw ua haujlwm engineering.
Raws li kev tsim kho vaj tse thoob ntiaj teb txuas ntxiv nthuav dav, ERW cov kav dej ua los ntawm cov qib carbon steel qauv tseem yog ib feem tseem ceeb ntawm kev tsim kho, kev thauj mus los, thiab kev lag luam engineering. Lawv versatility, manufacturing efficiency, thiab txhim khu kev qha mechanical kev ua tau zoo xyuas kom meej tias lawv yuav mus ua ib tug tseem ceeb luag hauj lwm nyob rau hauv niaj hnub pipeline networks thiab cov qauv siv.
