1. ** Dab tsi yog seamless casing? **
* Seamless casing yog hom ntawm cov yeeb nkab steel siv feem ntau hauv cov roj thiab roj zoo. Nws yog tsim kom tsis muaj kev sib tw weld ntev. Cov yeeb nkab tsim los ntawm tho ib lub zog, root steel billet (merpingrical thaiv (manpingrels kom ua tiav cov kab uas muaj qhov xav tau thiab cov phab ntsa tuab. Tus txheej txheem no tsim kev ua txuas ntxiv mus rau tom qab nws tag nrho ntev.
2. ** Dab tsi yog qhov txawv ntawm ERW thiab seamless casing? **
* ** Kev tsim kho txheej txheem: **
* ** ERW (hluav taws xob tiv thaiv welded): ** Ua los ntawm hlau chev (skelp) dov rau hauv ib lub cylindrical puab. Lub longitudinal npoo yog rhuab thiab fused ua ke hauv siab siv hluav taws xob siv hluav taws xob raws cov yeeb nkab qhov ntev.
* ** Seamless: ** Ua los ntawm tho thiab elongating ib tug steel billet. Muaj ** tsis muaj longitudinal vuam ** kev koom tes hauv thawj cov txheej txheem.
* ** WELD Seam: **
* ** ERW: ** Muaj qhov sib txawv, txuas ntxiv weld seam (tab sis feem ntau ua kom pom tau tsawg dua).
* ** Seamless: ** Muaj ** tsis muaj kev sib tw weld jeld **.
* ** ZAJ DOV DUA & HOMogeneity: **
* ** ERW: ** Weld Seam tuaj yeem yog qhov tsis muaj zog ntawm kev qaug zog lossis tsis sib xws rau niam txiv hlau, txawm tias niaj hnub txhim khu kev ntseeg tau. Cov qauv nplej ua raws li cov kev taw qhia me me.
* ** Seamless: ** Feem ntau muaj cov khaub ncaws zoo dua thiab ntev dua li qhov muaj zog ntau, tshwj xeeb tshaj yog nyob rau ib puag ncig siab thiab hauv kev xav tau.
* ** Tus nqi & Loj: **
* ** ERW: ** Feem ntau kim dua rau chaw tsim khoom. Npaj txhij muaj nyob rau hauv diameters loj thiab thinner phab ntsa.
* ** Seamless: ** kim dua vim yog cov txheej txheem ua haujlwm nyuaj. Keeb kwm muaj kev txwv ntawm cov tub ntxaij ntau heev thiab cov phab ntsa nyias nyias, txawm hais tias muaj peev xwm tau txais kev txhim kho ntau.
3. ** Dab tsi yog qhov txawv ntawm seamless thiab leeg? **
* ** SEAM: ** Ib txoj kab uas ob daim ntawm cov khoom (zoo li ntaub, hlau, yas) yog koom nrog lossis stitched ua ke. Nws yog qhov pom lossis cov qauv qauv ntawm kev sib txuas. Hauv cov kav dej, nws yog hais txog cov kab ntev heev.
* ** Seamless: ** Txhais tau txhais tau tias "tsis muaj ib qho seam." Piav qhia ib yam khoom uas tau tsim los ntawm ib daim ntawm cov khoom, tsis muaj koom nrog, khi, lossis cov kab sib tw raws nws qhov ntev lossis ib ncig. Nws cuam tshuam txuas ntxiv thiab kev sib xyaw.
4. ** Dab tsi yog seamless txhais tau nyob rau hauv vuam? **
* Nyob rau hauv cov ntsiab lus ntawm vuam, "seamless" ** tsis yog ** saib rau tus qauv * Kev tsim khoom * ntawm cov khoom siv hauv paus (zoo li cov yeeb nkab ntawm cov khoom). Hloov chaw, nws piav txog cov ** zoo thiab tshwm sim ntawm weld **.
* Ib qho "VAJEAMORT WELD" txhais tau tias Weld Bead tau ua tiav yog li ntawd (los ntawm kev sib tsoo, lossis cov kws tshaj lij ** rau hauv ib puag ncig lub hauv paus. Tsis muaj qhov pom ntawm Ridge, Valley, tsis txaus ntseeg, lossis tsis txuas ntxiv ntawm Weld hlau thiab lub hauv paus hlau. Kev hloov pauv yog tus thiab txuas ntxiv mus, ua rau weld zoo tsis pom.
5. ** Vim li cas nws hu ua seamless? **
* Nws hu ua "seamless" vim tias nws yog manufacture ** tsis muaj lub seam ntev (weld sib koom tes) **. Tsis zoo li cov kav dej ua los ntawm dov tiaj tus phaj lossis coil thiab vuam cov leeg pib ua ke los ntawm cov khoom siv hollow ua ke los ntawm cov khoom siv tshuab uas tsis tas yuav koom nrog cov npoo nrog kev tsim tawm. Cov khoom kawg yog lub raj tsis tu ncua nrog ** tsis muaj kev sib tshuam ** raws nws qhov ntev. Lub npe ncaj qha piav qhia txog kev txhais cov yam ntxwv ntawm nws txoj kev ntau lawm thiab ua rau qauv qauv.
