1. ** Dab tsi yog EFW Welded yeeb nkab? **
EFW sawv rau ** hluav taws xob fusion vuam **. Nws yog lub sijhawm dav dav rau cov kav dej ua los ntawm vuam cov txheej txheem uas muaj hluav taws xob arc yog siv los ua kom ob tus tub lim hlau ua ke thiab cov hlau hauv cov hlau sib koom ua ke. Hom feem ntau nyob hauv qab no yog ** submerged arc welded (pom) ** qhov twg arc yog submerged nyob rau hauv ib txheej flux. EFW \/ pom cov kav dej feem ntau yog siv rau phab ntsa loj dua thiab cov phab ntsa tuab, muaj nyob hauv cov kav dej thiab cov ntawv thov kev tsim qauv.
2. ** VEW sawv rau hauv vuam? **
ERW sawv rau ** Hluav Taws Xob Hluav Taws Xob Vuam **. Nws yog tus txheej txheem uas muaj hluav taws xob kub siab tam sim no dhau los ntawm cov npoo ntawm cov hlau txaij (skelp) tau tsim rau hauv cov yeeb nkab. Qhov tsis kam mus rau cov khoom siv tam sim no, melting cov npoo uas ces nias (forged) ua ke nyob rau hauv siab los tsim lub zog-state weld yam tsis muaj quav tais.
3. ** Yog erw yeeb nkab galvanized? **
** Tsis tas. ** ERW hais txog kev tshwj xeeb rau * Vuam txheej txheem * siv los tsim cov yeeb nkab. Ib cov yeeb nkab erw tuaj yeem tsim los ntawm cov hlau tsis muaj peev xwm ("dub yeeb nkab") lossis nws tuaj yeem yog galvanized * tom qab vuam. Galvanization (Txheej nrog Zinc) yog nyias cov txheej txheem thov rau kev tiv thaiv xeb. Yog li, Erw kav * tuaj yeem yog * galvanized, tab sis tsis yog txhua tus yog.
4. ** Dab tsi yog qhov txawv ntawm seamless thiab welded steel kav? **
* ** Ua Seamless Yeeb: ** Ua los ntawm tho ib lub nplua nuj ntawm cov hlau los tsim lub plhaub khoob, tom qab ntawd nqa nws cov txheej txheem dov thiab kos duab. Nws muaj ** tsis muaj welded seam ** raws nws qhov ntev.
* ** Welded yeeb nkab: ** Ua los ntawm kev sib sau tiaj tus hlau phaj lossis sawb) mus rau hauv cov txheej txheem cylindrical ua ke (siv cov txheej txheem xws li ERW, EFW \/ pom, thiab lwm yam). Nws ** muaj ib qho kev sib tw tso tawm **.
** Qhov sib txawv tseem ceeb: **
* ** SEAM: ** Seamless tsis muaj; Welded muaj ib tug.
* ** Lub zog \/ cov ris tsho sib xyaw: ** Seiformless yeeb nkab feem ntau muaj ntau cov yam ntxwv muaj zog ntau nyob ib ncig ntawm nws qhov kev ncig thiab feem ntau nyiam rau cov ntawv thov siab. Weld seam tuaj yeem ua lub peev xwm tsis muaj zog (txawm tias niaj hnub vuam yog ntseeg heev).
* ** Qhov Loj \/ Tus Nqi: ** Seamless yog tsawg nyob rau hauv lub cheeb thiab feem ntau kim dua. Welded yeeb nkab tuaj yeem tsim nyob rau hauv cov uas diameters loj heev thiab feem ntau yog ua tau zoo dua.
* ** NTO QAIB \/ INTERNITY TXHUA YAM: ** Seamless Feem Ntau Muaj Qhov Tsaus Ntuj Sab Hauv. Welded cov yeeb nkab tuaj yeem muaj qhov ua tiav smoother tab sis tej zaum yuav muaj weld Bead tsis xwm yeem sab hauv \/ tawm.
* ** Phab ntsa tuab: ** Seamless heev yuav muaj ntau ntau yam sib txawv hauv phab ntsa tuab; Welded yeeb nkab muaj ntau raws li phab ntsa tuab.
5. ** Puas yog erw yeeb nkab muaj ib leeg? **
** Yog, Erw yeeb nkab muaj cov leeg. ** Nws yog tsim los ntawm kev tsim sawb hlau thiab vuam lub longitudinal npoo ua ke siv cov txheej txheem hluav taws xob ua ke siv cov txheej txheem hluav taws xob. Welded sib koom ua ke sau tag nrho ntev ntawm cov yeeb nkab thiab yog lub npe hu ua Weld Seam lossis Fusion kab. Txawm li cas los xij, cov txheej txheem ya tshiab no tsim kom muaj ib qho zoo heev, yuav luag pom ntawm cov leeg uas muaj zog npaum li lub hauv paus hlau nws tus kheej.
