**1. Dab tsi yog seamless welded yeeb nkab?
Lo lus "seamless welded yeeb nkab" yog qhov tsis sib xws. Cov yeeb nkab tsis tuaj yeem yog seamless thiab welded. Cov no yog ob txoj kev tsim khoom sib txawv.
* ** Seamless Yeeb Nkab ** yog tsim los ntawm cov khoom cylindrical ntawm cov hlau (ib daim hlau) uas yog cua sov thiab tho los ntawm qhov chaw los ua ib lub raj hollow yam tsis muaj seams lossis pob qij txha.
* ** Welded Yeeb Nkab ** yog tsim los ntawm dov lub tiaj tiaj steel phaj lossis daim ntawv (skelp) rau hauv cov duab cylindrical thiab tom qab ntawd vuam cov seam raws nws qhov ntev mus koom nrog cov npoo.
Yog li, ib lub yeeb nkab yog ** seamless ** lossis ** welded **, tab sis tsis yog ob qho tib si.
**2. Dab tsi yog qhov txawv ntawm welded thiab seamless stainless hlau kav?**
Thawj qhov sib txawv yog nyob rau hauv yuav ua li cas lawv raug tsim, uas cuam tshuam rau lawv cov yam ntxwv.
* ** Welded Stainless Hlau Yeeb Nkab:** Pib raws li ib lub tiaj tiaj ntawm stainless hlau, uas yog tsim rau hauv ib lub raj thiab lub longitudinal seam yog welded. Cov txheej txheem no tuaj yeem tsim qhov zoo nkauj heev thiab du sab hauv. Txawm li cas los xij, cov welded seam tuaj yeem yog qhov muaj peev xwm ntawm kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive, yog tias qhov vuam tsis raug kho. Nws feem ntau yog tus nqi ntau dua - ua haujlwm tau zoo thiab muaj nyob hauv qhov ntev txuas ntxiv.
* ** Seamless Stainless Hlau Yeeb Nkab:** Tsim los ntawm extruding ib tug khoom billet ntawm stainless hlau rau hauv lub hollow raj. Vim nws tsis muaj welded seam, nws yog inherently muaj zog thiab ntau yam nyob rau hauv nws lub zog nyob ib ncig ntawm tag nrho cov ncig. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau siab -siab, siab - kub, los yog cov ntawv thov corrosive heev uas qhov kev ncaj ncees ntawm cov weld yuav muaj kev txhawj xeeb. Nws feem ntau kim dua vim cov txheej txheem tsim khoom.
** 3. Dab tsi yog qhov txawv ntawm welded raj thiab seamless raj?
Qhov sib txawv ntawm "tube" thiab "pipe" yog ib qho ntawm cov ntsiab lus thiab daim ntawv thov, tab sis qhov sib txawv ntawm kev tsim khoom tseem zoo ib yam.
* ** Welded Tube: ** Tsim los ntawm kev tsim cov hlua ntawm cov hlau rau hauv cov duab cylindrical thiab vuam cov seam. Welded raj feem ntau yog siv rau cov qauv siv (xws li tes tuav), cov khoom siv kho tshuab, thiab qis - cov ntawv siv siab uas qhov tseeb sab nraud qhov ntev thiab kev zoo nkauj yog qhov tseem ceeb. Nws feem ntau yog kev lag luam ntau dua.
* ** Seamless Tube: ** Ua los ntawm kev tho lub pob zeb kom tsim tau ib qho hollow seem yam tsis muaj seam. Seamless raj yog xaiv rau nws lub zog superior thiab kev ntseeg tau. Nws yog siv nyob rau hauv siab - kev nyuaj siab xws li hydraulic thooj voos kheej kheej, bearing haiv neeg, thiab siab - cov cuab yeej siv siab qhov chaw uas muaj ib tug weld yuav yog ib tug tsis muaj zog yam ntxwv.
** 4. Qhov txawv ntawm ERW thiab Smls yeeb nkab yog dab tsi?**
ERW thiab SMLS xa mus rau cov yeeb nkab tshwj xeeb tsim.
* ** ERW Yeeb Nkab (Electric Resistance Welded): ** Qhov no yog ib hom welded yeeb nkab. Cov npoo ntawm cov hlau sawb yog rhuab siv hluav taws xob tam sim no thiab tom qab ntawd sib koom ua ke nyob rau hauv siab los tsim cov vuam, tsis tas siv cov hlau muab tub lim. Cov txheej txheem ERW niaj hnub no yog qhov siab heev thiab tsim cov welds muaj zog heev.
* ** SMLS Yeeb Nkab (Seamless): ** Qhov no yog daim ntawv luv rau seamless yeeb nkab. Raws li tau piav qhia ua ntej, nws yog tsim los ntawm cov khoom siv pob zeb uas tsis muaj qhov ntev weld seam. Nws yog lub npe hu rau nws lub peev xwm los daws cov kev ntxhov siab dua thiab nws lub zog tsis sib xws.
Qhov sib txawv tseem ceeb yog qhov muaj qhov sib txuas hauv ERW yeeb nkab, thaum SMLS yeeb nkab tsis muaj qhov sib txuas.
**5. Koj puas tuaj yeem txuas ERW yeeb nkab?
Yog lawm, koj tuaj yeem txuas ERW yeeb nkab. Lub npe "ERW" tsuas yog hais txog yuav ua li cas cov yeeb nkab nws tus kheej raug tsim tawm (qhov ntev seam). Thaum nws los koom nrog ERW cov kav dej hauv thaj teb los ua cov raj xa dej lossis cov txheej txheem, cov txheej txheem vuam txheej txheem xws li arc vuam (SMAW, GTAW, GMAW) yog siv los txuas cov kav kawg ntawm cov kav dej ua ke. Lub teb welds yog tsim rau ntawm cov yeeb nkab qhov ncig, tsis yog ntawm nws ua ntej -tuaj yeem ntev ERW seam.
