Hluav taws xob Resistance Welded steel kav, feem ntau hu ua ERW kav dej, sawv cev rau ib qho ntawm cov khoom siv dav tshaj plaws ntawm welded steel kav hauv kev lag luam niaj hnub no. Tsim los ntawm kev sib sau ua ntu zus thiab siab - cov txheej txheem vuam zaus, ERW cov kav dej tau paub txog lawv cov kev ua haujlwm siab, qhov sib xws, thiab tus nqi- ua tau zoo. Tau ntau xyoo, kev txhim kho hauv cov khoom siv raw zoo thiab vuam tshuab tau ua rau ERW cov kav dej kom nthuav dav rau hauv cov ntawv thov uas xav tau ntxiv, xws li kev thauj mus los rau cov khoom siv hluav taws xob.
Cov txheej txheem tsim khoom thiab cov yam ntxwv ua haujlwm
Siab -Txoj Cai Vuam Zaus
Lub ntsiab lus ntawm ERW steel kav yog nyob rau hauv lawv cov txheej txheem vuam. Steel coils yog thawj uncoiled thiab tsim rau hauv ib tug cylindrical zoo los ntawm ib tug series ntawm rollers. Cov npoo yog ces cua sov siv high - zaus hluav taws xob tam sim no thiab nias ua ke los tsim ib txoj kab ntev weld seam. Tsis zoo li ib txwm fusion welding, cov txheej txheem no tsis xav tau cov khoom siv muab tub lim, uas ua kom muaj qhov huv thiab tsis sib xws weld cheeb tsam nrog cov impurities tsawg.
Niaj hnub no ERW cov kab ntau lawm suav nrog kev kho cua sov hauv online thiab seam normalization, uas ua kom zoo dua microstructure ntawm thaj chaw weld thiab txhim kho nws cov kev ua haujlwm zoo. Raws li qhov tshwm sim, lub vuam seam tuaj yeem ua tiav qib siab piv rau cov hlau hauv paus, ua kom muaj kev ntseeg tau zoo ntawm cov yeeb nkab.
Dimensional Accuracy thiab Surface Quality
ERW kav dej yog tus cwj pwm los ntawm nruj qhov ntev kam rau ua thiab du nto tiav. Cov txheej txheem txuas ntxiv ua kom zoo ib yam ntawm txoj kab uas hla thiab phab ntsa tuab, uas yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas yuav tsum tau ua kom haum zoo - nce thiab sib dhos. Tsis tas li ntawd, qhov tsis muaj qhov sib tshooj welds los yog kev txhawb nqa ntau dhau ua rau muaj qhov huv hauv sab hauv, txo cov dej tsis kam hauv cov dej thauj mus los.

Cov Qib thiab Cov Qauv
Common Steel Qib
ERW kav dej feem ntau yog tsim los ntawm cov pa roj carbon steel thiab qis- alloy steel, nrog cov qhab nia xaiv raws li daim ntawv thov. Cov qauv sib xws suav nrog ASTM A53 rau kev dav dav - lub hom phiaj piping, API 5L rau roj thiab roj tsheb thauj mus los, thiab EN 10219 rau kev siv cov qauv. Cov ntaub ntawv no muab qhov sib npaug ntawm lub zog, ductility, thiab weldability, ua ERW kav dej haum rau ntau yam kev ua haujlwm.
Nyob ntawm qib, cov khoom muaj zog tuaj yeem sib txawv ntawm kwv yees li 235 MPa mus rau ntau dua 450 MPa. Qhov no tso cai rau cov engineers xaiv cov kev qhia tsim nyog raws li qhov siab, load, thiab ib puag ncig yam.
Ua raws li International Standards
Txhawm rau kom muaj kev ua tau zoo ib yam, ERW kav dej yuav tsum ua tau raws li cov qauv thoob ntiaj teb nruj uas suav nrog cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov kev sim ntsuas. Kev kuaj hydrostatic, tshuaj xyuas ultrasonic, thiab kev ntsuas tam sim no feem ntau yog ua haujlwm los xyuas qhov kev ncaj ncees ntawm vuam thiab kuaj xyuas qhov tsis xws luag.
| Txuj | Daim Ntawv Thov Scope | Cov Lus Qhia Tseem Ceeb |
|---|---|---|
| ASTM A53 | Cov kav dej, roj, thiab cov kav dej | Mechanical zog thiab kev ntsuas siab |
| API 5L | Roj thiab roj kis tau tus mob | Siab zog thiab toughness |
| TS EN 10219 | Structure engineering | Dimensional thiab mechanical sib xws |
| GB/T 3091 | Kev thauj kua dej | General kev ua tau zoo thiab durability |
