Hluav taws xob Resistance Welded carbon steel kav, feem ntau hu ua ERW carbon steel kav, yog cov feem ntau siv steel yeeb nkab khoom nyob rau hauv niaj hnub industrial systems. Tsim los ntawm cov pa roj carbon steel coils los ntawm kev sib sau ua ntu zus thiab siab - cov txheej txheem vuam zaus, cov kav dej no muaj nuj nqis rau lawv cov khoom zoo ib yam, tsim tau zoo, thiab tus nqi- ua tau zoo. Nrog kev txhim kho txuas ntxiv hauv kev siv thev naus laus zis thiab kev tswj kom zoo, ERW carbon steel kav tau dhau los ua kev daws teeb meem rau ntau yam kev siv, suav nrog kev thauj mus los, kev tsim vaj tsev, thiab kev tsim khoom siv tshuab.
Txhais thiab Cov yam ntxwv tseem ceeb ntawmERW Carbon Steel Yeeb Nkab
Material Composition thiab Mechanical Properties
ERW carbon steel kav yog tsim los ntawm qis-carbon lossis nruab nrab- carbon steel, feem ntau muaj nruab nrab ntawm 0.05% thiab 0.25% carbon. Qhov kev sib xyaw no ua kom muaj kev sib npaug zoo ntawm lub zog, ductility, thiab weldability, ua rau cov khoom haum rau ob qho tib si siab -cov kabmob thiab cov qauv siv. Cov qauv zoo xws li ASTM A53, API 5L, thiab EN 10219 txhais cov tshuaj muaj pes tsawg leeg thiab kev ua haujlwm txhua yam yuav tsum tau ua rau kev siv sib txawv.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, ERW kav feem ntau pom muaj zog tawm los ntawm 235 MPa txog 450 MPa, nyob ntawm qib. Qhov no tso cai rau lawv tiv taus lub siab sab hauv thiab sab nraud loads. Tsis tas li ntawd, lawv cov phab ntsa tuab tuab ua rau muaj kev ntxhov siab ruaj khov thaum lub sijhawm ua haujlwm.
Cov yam ntxwv zoo thiab kev ua tau zoo
Lub ntsiab lus tseem ceeb ntawm ERW cov kav dej yog qhov ntev ntawm qhov vuam seam tsim thaum lub sij hawm siab - zaus kuj welding txheej txheem. Tsis zoo li cov kav dej seamless, ERW cov kav dej muaj qhov zoo ntawm qhov raug thiab qhov zoo ntawm qhov zoo vim lawv txoj kev txuas ntxiv. Sab hauv thiab sab nrauv yog feem ntau du, uas txo cov dej tsis kam thiab txhim kho kev ua haujlwm ntawm cov kua dej.
Cov txheej txheem tsim khoom niaj hnub no suav nrog kev kho cua sov ntawm weld seam, uas txhim kho microstructure ntawm thaj chaw weld thiab xyuas kom meej tias nws cov cuab yeej siv tau zoo piv rau cov khoom siv hauv paus. Qhov no ua rau txhim kho tag nrho lub zog thiab kev ntseeg siab ntawm cov yeeb nkab.

Kev tsim cov txheej txheem ntawm ERW Carbon Steel Pipes
Nruam tsim thiab Vuam txheej txheem
Kev tsim khoom ntawm ERW carbon steel kav ua raws li txoj hauv kev txuas mus ntxiv thiab ua haujlwm siab heev. Nws pib nrog steel coils uas yog uncoiled, leveled, thiab pub rau hauv ib qho kev sib sau. Los ntawm ib tug series ntawm rollers, lub tiaj tus sawb yog maj mam shaped mus rau hauv ib daim ntawv cylindrical.
Thaum cov npoo ntawm cov sawb ua raws, siab - zaus hluav taws xob tam sim no tau siv los ua kom sov cov npoo sai. Nyob rau hauv lub siab los ntawm nyem chais, cov rhuab npoo yog fused ua ke, ua ib tug khoom - xeev weld yam tsis siv cov ntaub ntawv muab tub lim. Txoj kev no ua kom huv si weld seam nrog tsawg impurities.
Tom qab welding, cov yeeb nkab yuav tsum tau sizing thiab straightening txheej txheem kom ua tiav qhov ntev. Nws yog ces txiav mus rau qhov yuav tsum tau ntev raws li cov neeg siv khoom specifications.
Ncej -Kev kho Weld thiab Tswj kom zoo
Tom qab thawj zaug tsim thiab vuam theem, cov txheej txheem ntxiv yog siv los xyuas kom meej qhov kev ua tau zoo thiab kev ntseeg siab ntawm cov yeeb nkab. Kev kho cua sov feem ntau yog ua los txo cov kev ntxhov siab uas seem thiab ua kom zoo dua cov qauv ntawm qhov chaw weld. Cov kauj ruam no yog qhov tseem ceeb hauv kev ua kom cov khoom sib xws ntawm txhua lub yeeb nkab.
Kev tswj kom zoo ua lub luag haujlwm tseem ceeb thoob plaws hauv cov txheej txheem tsim khoom. Tsis yog-kev kuaj kev puas tsuaj xws li kev kuaj ultrasonic thiab kev tshuaj ntsuam xyuas tam sim no yog siv los txheeb xyuas qhov tsis xws luag hauv qhov vuam seam. Kev sim hydrostatic kuj tseem ua tau los txheeb xyuas cov yeeb nkab lub siab ua haujlwm thiab kev ua haujlwm zoo.
| Qib ntau lawm | Txheej txheem piav qhia | Ua kom pom tseeb zoo |
|---|---|---|
| Kev Npaj Coil | Uncoiling thiab leveling | Nto thiab flatness tswj |
| tsim | Yob sib sau ua cov yeeb nkab | Dimensional sib xws |
| Vuam | Siab -frequency resistance | Weld seam kev ncaj ncees |
| Kev tshuaj xyuas | NDT thiab kev ntsuas siab | Kev kuaj pom tsis zoo thiab kev ntseeg tau |
