Thaum tshuaj xyuas cov ntawv qhia tshwj xeeb ntawm MIDAS carbon steel ERW kav, ntau tus neeg siv khoom pom tias peb daim ntawv teev npe muaj cov ncauj lus kom ntxaws dua li cov qauv catalogues. Qhov no tsis yog ntxiv cov duab xwb. Kos rau xyoo ntawm kev txhawb nqa rau cov dej hauv nroog & dej ntws, cov txheej txheem piling, thiab cov dej xa mus, peb tsom mus rau cov ntsiab lus yooj yim saib xyuas uas feem ntau ua rau kev rov ua haujlwm ntawm qhov chaw, weld to, thiab kev tsis txaus siab.
Phab ntsa Thickness kam rau ua - Tsis tsuas yog tso siab rau tus qauv ± 10% txwv
Cov qauv dav dav xws li ASTM A53 thiab API 5L qhia txog phab ntsa tuab ntawm ± 10%, uas feem ntau cov neeg muag khoom tsuas yog ua raws li qhov yuav tsum tau ua tsawg kawg nkaus. Thaum lub sij hawm tiag tiag yeeb nkab haum, loj thickness variation ntawm ob kawg ntawm ib tug yeeb nkab yooj yim ua rau ntau misalignment ntawm haum-up. Welders yuav tsum tau siv sij hawm ntau ntawm kev sib tsoo, thiab nyob rau hauv cov xwm txheej hnyav tag nrho cov yeeb nkab seem yog scrapped.
MIDASsiv kev tswj hwm nruj dua rau cov kav dej ERW. Phab ntsa thickness kam rau ua yog nruj rau ± 7.5%, thaum lub thickness sib txawv ntawm lub taub hau thiab tus Tsov tus tw ntawm ib tug yeeb nkab yog txwv kom tsawg dua los yog sib npaug zos rau 0.2 hli. Cov phab ntsa tuab zoo ib yam txhim kho qhov kev vam meej ib zaug ntawm kev sib tsoo, txo kev siv cov khoom siv vuam thiab kev ua haujlwm, thiab ua kom cov kev sim hydrostatic dhau ntawm thawj qhov kev sim.
Weld Quality Stands as the Core Control Point of ERW Pipes
Qhov sib txawv ntawm ERW cov kav dej thiab cov kav dej seamless yog nyob rau hauv cov kav ntev. Feem ntau ntawm ERW yeeb nkab tsis ua haujlwm thoob plaws hauv kev lag luam yog los ntawm qhov tsis xws luag: fusion tsis tiav, slag inclusion, fusion offset, thiab kev tswj tsis raug ntawm vuam residual stress.
MIDAS siv peb txoj kev tswj xyuas qhov vuam uas tuaj yeem teev tseg hauv kev lees paub:
100% online eddy kuaj tam sim no raws tag nrho cov weld seam, es tsis txhob batch sampling soj ntsuam;
Online annealing rau lub weld tshav kub-tshuaj tiv thaiv cheeb tsam kom txo lub zos hardness thiab tiv thaiv weld tawg thaum lub sij hawm tom ntej bending los yog threading;
Hydrostatic kuaj ntawm cov qauv los ntawm txhua batch nyob rau hauv tuav tej yam kev mob tshaj cov qauv yooj yim los xyuas kom meej weld siab nruj.
Thaum nug, koj tuaj yeem tsom mus rau ob lub ntsiab lus tseem ceeb: qhov kev pab them nqi ntawm kev kuaj tsis muaj kev puas tsuaj ntawm cov welds thiab seb puas muaj qhov sib txuas.
Impact Test Temperature Yuav Tsum Ua Raws Li Qhov Kev Ntsuas Qhov Ntsuas Qhov Ntsuas
Cov qhab nia suav nrog Q355, L245 thiab X42 feem ntau raug cim nrog kev ntsuas kev cuam tshuam ntawm 0 degree, uas tsuas yog tsim nyog rau qhov chaw me me. Rau tej yaam num nyob rau hauv cov cheeb tsam frigid, faus qhov kub thiab txias, los yog tsis tshua muaj-kub xov xwm kev pab cuam, qhov 0℃cuam tshuam qhov Performance index tsis tuaj yeem tiv taus nkig puas ntsoog tshwm sim los ntawm ductile-brittle hloov ntawm carbon hlau. Cov yeeb nkab tawg tuaj yeem tshwm sim thaum lub sij hawm ntsuas siab.
MIDAS tuaj yeem muab cov kev ntsuas kub qis ntawm -20℃lossis -40℃raws li qhov project, nrog rau cov ntaub ntawv xeem thib peb. Cov khoom no me ntsis nce tus nqi yuav khoom, tab sis nws tseem qis dua qhov kev puas tsuaj los ntawm cov kav dej rupture thiab tag nrho-kab rectification.
Cov txheej txheem kho deg yuav tsum sib haum nrog cov txheej txheem hauv qab los tiv thaiv corrosion
Nws yog ib qho kev coj ua rau liab qab ERW cov kav dej kom tiv thaiv xeb-tiv thaiv roj. Yog tias 3PE txheej lossis epoxy txheej yuav raug siv tom qab, cov nplai zeb thiab cov roj uas tsis muaj xeb ntawm cov yeeb nkab yuav ncaj qha ua rau cov txheej txheej adhesion tsis muaj zog thiab ua rau muaj kev pheej hmoo ntawm txheej txheej.
MIDAS muaj ntau qhov kev xaiv ntawm qhov chaw sib phim rau cov neeg siv khoom tom qab ua tiav: Sa2.5 qib sandblasting, weldable primer, los yog liab qab xa. Peb kuj tau txais cov khoom ntim ntim cov dej noo sib cais rau kev xa tawm hiav txwv thiab kev thauj mus los hauv av. Ntau qhov dej num tau ntsib hnyav xeb thaum cov yeeb nkab tuaj txog, yuav tsum tau siv cov xuab zeb blasting ua ntej txheej. Defining deg tej yam kev mob ua ntej zam tsis pub ntxiv cov txheej txheem.
Tag Nrho Traceability los ntawm Cua Sov Number los txhawb kev soj ntsuam thib peb
Txhua MIDAScarbon steel ERW yeeb nkabyog cim nrog stamping nrog rau cov xov tooj cua sov, batch tooj, qhov ntev, thiab cov ntaub ntawv tsim khoom, nrog rau MTC ua raws EN 10204 3.1.
Cov ntaub ntawv traceability yog qhov yuav tsum tau txais kev lees paub rau cov haujlwm xa tawm thiab ua haujlwm saib xyuas los ntawm peb tog xws li SGS thiab BV. Thaum tsis pom qhov tsis sib haum xeeb hauv cov qauv, peb tuaj yeem nrhiav cov khoom lag luam sai ntawm cov khoom siv hluav taws xob sib txuas thiab tiv thaiv kev tsis sib haum xeeb ntawm kev tsis lees paub ntawm tag nrho cov khoom xa tuaj.
Kev xaiv qhov kev xav: txhais tau tias Daim Ntawv Thov Ciam Teb rau ERW Pipes
MIDAS tsom xam cov xwm txheej ntawm daim ntawv thov thiab yeej tsis pom zoo ERW kav dej rau kev pabcuam tshaj li lawv lub peev xwm:
Zoo dua: Kev siv dej & dej ntws, cov kav dej tiv thaiv hluav taws, kev txhawb nqa cov txheej txheem, pawg casing thiab cable tiv thaiv conduits nrog cov nqi zoo heev.
Muaj peev xwm tswj tau: Cov kev pabcuam nruab nrab thiab qis qis qis dua lossis sib npaug li 16 bar, cov pa roj & roj sib sau ua ke thiab cov pa roj hauv nroog. Xaiv API 5L PSL1 / PSL2 qib nrog ua tiav NDT thiab ntsuas hydrostatic kom muaj kev nyab xeeb txaus.
Tsis pom zoo: Cov kav dej siab ntev ntev, kev pabcuam kub kub tsis tu ncua, hloov pauv kev sib tw, cov phab ntsa tuab tshaj 20 hli, thiab qhov kub tsis tshua muaj siab heev. Cov kav dej tsis sib haum lossis LSAW kav dej yog tsim nyog rau cov xwm txheej zoo li no.
Ntau qhov haujlwm yav dhau los tau xaiv ERW cov kav dej los txiav nyiaj txiag rau kev pabcuam tshaj li kev txwv tsim thiab xaus rau kev hloov tag nrho cov kav dej. MIDAS cov kws tshaj lij pab pawg yuav ua haujlwm ceeb toom cov neeg siv khoom ntawm kev ua haujlwm muaj kev pheej hmoo ciam teb thaum hais lus.
Txhua qhov ntsuas ntawm daim ntawv qhia tshwj xeeb sib raug rau cov txheej txheem ntawm qhov chaw, kev lees paub, thiab cov khoom siv. Tus nqi tseem ceeb ntawm MIDAS carbon steel ERW kav dej tsis yog cov duab ntxim nyiam ntawm daim ntawv, tab sis txhim khu kev qha kev ua raws li kev tsim kho thiab kev lees paub tom qab cov kav dej tuaj txog ntawm qhov chaw, txhawb kev sib koom tes ntev ntev. Cov qauv siv tau npog ASTM A53 Gr.B, API 5L, EN 10219, thiab GB / T 3091. Rau cov qib tshwj xeeb, phab ntsa thickness ranges, lossis txiav ntev, hu rau peb cov kev muag khoom kom paub meej cov ntsiab lus raws li koj qhov project.
