Hauv kev lag luam steel yeeb nkab, ERW steel kav thiab CEW steel kav (piv txwv li, Txias-Drawn Electric Welded kav) yog ob hom khoom siv welded steel yeeb nkab. Txawm hais tias ob qho tib si muaj nyob rau hauv qeb ntawm welded kav, lawv muaj qhov sib txawv tseem ceeb hauv kev tsim khoom, cov yam ntxwv ntawm kev ua haujlwm, kev siv cov xwm txheej, thiab lwm yam. Kev nkag siab txog qhov sib txawv no pab cov engineers thiab cov neeg yuav khoom txiav txim siab muaj txiaj ntsig hauv qhov project tsim thiab xaiv cov khoom siv. Kab lus no qhia meej txog qhov sib piv ob los ntawm ntau qhov ntev xws li cov txheej txheem tsim khoom, ntsuas kev ua tau zoo, thiab daim ntawv thov scenarios, nrog rau kev tsom mus rau kev tshuaj xyuas qhov zoo ntawm ERW steel kav.
I. Kev sib piv ntawm Cov Ntsiab Cai thiab Cov Txheej Txheem Kev Tsim Khoom
1. Txhais thiab Manufacturing txheej txheem ntawmERW steel yeeb nkab
ERW stands rau Electric Resistance Welded steel yeeb nkab. Nws txoj kev tsim khoom feem ntau suav nrog:
- Siv steel coils ua raw khoom, flattening thiab uncoiling lawv mus rau hauv steel strips;
- Maj mam khoov cov hlau strips rau hauv lub voj voog tubular los ntawm kev sib sau yob;
- Thaum tsim cov yeeb nkab dawb paug, siv high- zaus tam sim no los ua kom sov cov yeeb nkab npoo kom yaj thiab txuas rau hauv cov kav dej;
- Tom qab vuam, ua kom ncaj, ruaj -ntev txiav, thiab kev kho cua sov tsim nyog lossis kev kho saum npoo.
Lub weld ntawm ERW steel kav yog ib tug longitudinal ncaj seam. Los ntawm niaj hnub high - zaus vuam tshuab, lub zog vuam tuaj yeem nyob ze ntawm cov khoom siv hauv paus, ua rau nws tsim nyog rau kev tsim khoom loj.
2. Kev txhais thiab kev tsim khoom ntawm CEW Steel Pipes
CEW sawv cev rau Cold Electric Vuam yeeb nkab, qee zaum kuj hu ua txias - kos hluav taws xob welded yeeb nkab lossis CDW steel yeeb nkab. Nws txoj kev tsim khoom yog:
- Ua ntej, tsim cov kav dej welded yooj yim siv ERW lossis lwm yam txheej txheem vuam;
- Tom qab ntawd ua haujlwm txias-kev kos duab ntawm cov kav dej welded hauv lub xeev txias;
- Thaum lub caij txias - txheej txheem kos duab, cov kav dej dhau los ntawm qhov tseeb tuag kom ua tiav qhov kev tswj xyuas nruj dua thaum txhim kho nto tiav thiab cov khoom siv kho tshuab;
- Tom qab txias -kos duab, ntxiv ncej- cov txheej txheem kho mob xws li annealing lossis normalizing yuav ua tau.
Cov txheej txheem kev kos duab txias yog qhov tseem ceeb ntawm CEW steel kav, uas ua rau cov kav hlau txuas tau zoo dua li cov kav hlau ERW zoo tib yam raws li qhov tseeb qhov tseeb thiab qhov zoo ntawm qhov chaw.
II. Kev sib piv: ERW vs. CEW (Cold-Drawn Electric Welded Pipes)
Cov lus hauv qab no qhia txog kev sib piv ntawm cov cim tseem ceeb ntawm ob hom steel kav:
| Cov khoom sib piv | ERW steel yeeb nkab | CEW (Cold{0}}Drawn Electric Welded Pipe) |
|---|---|---|
| Kev tsim khoom | Siab - zaus hluav taws xob tsis kam vuam txoj kev | Vuam ua ntej, tom qab ntawd txias - kev kos duab |
| Weld yam ntxwv | Pom tseeb weld tab sis siab zog | Weld yuav zoo dua tom qab txias- kos duab |
| Dimensional raug | General | Siab precision nrog me deviations |
| Nto tiav | Zoo | Superior, haum rau precision daim ntaub ntawv |
