ERW yeeb nkab hlau
ERW yeeb nkab (hluav taws xob tsis kam welded yeeb nkab) thiab CDW yeeb nkab (txias kos welded yeeb nkab) yog ob qho txheej txheem ntau lawm sib txawv rau cov yeeb nkab hlau welded.
1. Cov txheej txheem ntau lawm
| Cov khoom sib piv | ERW yeeb nkab (hluav taws xob tsis kam vuam yeeb nkab) | CDW yeeb nkab (txias rub yeeb nkab vuam) |
| Lub npe tag nrho | Hluav Taws Xob Tiv Thaiv Welded Yeeb Nkab | Cov Yeeb Nkab Welded Txias |
| Cov txheej txheem tsim | Ntug ntawm lub phaj hlau raug cua sov los ntawm cov hluav taws xob siab thiab raug nias thiab vuam rau hauv cov duab | Ua ntej welded rau hauv cov kav dej, tom qab ntawd txias rub (kev kho mob txias deformation) |
| Txoj kev vuam | Kev Vuam Zaus Siab (HFW / ERW) | ERW lossis argon arc welding (TIG) feem ntau yog siv rau kev vuam. |
| Kev ua tom qab | Ncaj qha sizing thiab txiav tom qab welding | Kev kos duab txias (txias dov) tiav tom qab vuam |
2. Cov yam ntxwv ua tau zoo
ERW yeeb nkab
Qhov tseeb ntawm qhov ntev: Dav dav (± 0.5% ~ 1% sab nraud txoj kab uas hla kam rau siab)
Qhov zoo ntawm qhov chaw: Lub vuam yog me ntsis pom tseeb thiab xav tau polished
Cov khoom siv kho tshuab: Lub zog nyob ntawm cov khoom siv niam txiv, thiab tej zaum yuav muaj kev mos mos hauv thaj chaw vuam
Kev ntxhov siab seem: Tsawg (tsuas yog kev kho cua sov yooj yim tom qab vuam)
Cov yeeb nkab CDW
Qhov tseeb ntawm qhov ntev: siab heev (hauv ± 0.1 hli, tsim nyog rau kev ua kom raug)
Qhov zoo ntawm qhov chaw: du nto, tsis muaj oxide nplai (polished tom qab kos duab txias)
Cov khoom siv kho tshuab: ua haujlwm txias, lub zog nce ntxiv 20% ~ 30%
Kev ntxhov siab seem: siab (yuav tsum tau annealing kom tshem tawm kev ntxhov siab txias)
3. Cov xwm txheej ntawm daim ntawv thov
ERW: cov kav dej roj / roj, cov kav dej tsim kho vaj tse (scaffolding), cov kav dej kua qis (GB / T 3091)
CDW: hydraulic cylinders, precision mechanical parts (xws li bearing sleeves), automobile transmission shafts (cheeb tsam uas muaj qhov yuav tsum tau ua kom raug qhov ntev)
Cov qauv dav dav ntawm cov hom
ERW: API 5L (cov yeeb nkab kav dej), ASTM A53 (cov yeeb nkab qauv), EN 10219 (Cov yeeb nkab vuam txheem European)
CDW: ASTM A519 (cov yeeb nkab txias uas raug), DIN 2391 (cov yeeb nkab German uas raug siab)
CDW yeeb nkab = ERW yeeb nkab + kos duab txias, nrog rau qhov ntev meej dua thiab muaj zog dua, tab sis kuj muaj nqi siab dua.
Cov yeeb nkab ERW yog qhov tsim nyog rau cov hom phiaj dav dav, thaum cov yeeb nkab CDW yog siv rau hauv kev siv tshuab ua haujlwm siab.
Yog tias kev ua haujlwm ntawm CDW yeeb nkab xav tau kev txhim kho ntxiv, kev kho annealing tuaj yeem ntxiv (kom tshem tawm kev ntxhov siab ua haujlwm txias).
