Kev sib piv ntawm EFW thiab ERW Manufacturing Processes
Hauv kev lag luam piping kev lag luam, Electric Fusion Welded (EFW) thiab Hluav Taws Xob Resistance Welded (ERW) yog ob txoj hauv kev los tsim cov kav hlau welded. Thaum ob qho tib si pib los ntawm steel coil los yog phaj, lawv cov vuam mechanisms thiab cov yeeb nkab ua yeeb yam yog qhov sib txawv, ua rau txhua qhov tsim nyog rau cov kev pabcuam tshwj xeeb.
ERW: Ua tau zoo siab -Vuam zaus
Hluav taws xob Resistance Vuam (ERW) cuam tshuam nrog txias - ua cov hlau sawb rau hauv cov duab cylindrical. High- zaus tam sim no (HFW) yog tom qab ntawd dhau los ntawm cov npoo ntawm cov sawb los ua kom sov. Cov npoo yog nias ua ke los ntawm chais los tsim ib qho forged weld yam tsis siv cov hlau muab tub lim. ERW paub txog kev ua haujlwm siab ceev thiab qhov zoo ntawm qhov raug, feem ntau yog siv rau me me - mus rau - cov kav dej nruab nrab (txog 24 ").
EFW: Siab -Kev ncaj ncees Fusion Vuam
Hluav taws xob Fusion Vuam (EFW) suav nrog kev siv ib lossis ntau qhov hluav taws xob arcs thiab ntxiv cov hlau muab tub lim kom fuse cov npoo ntawm cov hlau phaj ua ke. Cov txheej txheem no zoo ib yam li SAW (Submerged Arc Welding). EFW feem ntau yog siv rau loj - cov kav dej lossis cov kav dej uas muaj phab ntsa tuab heev. Kev siv cov hlau muab tub lim thiab sib sib zog nqus fusion tso cai rau cov kav dej EFW los tswj cov kev kub ntxhov thiab kub ntau dua li tus qauv ERW.
Technical Sizing thiab Material Capabilities
ERW kav dej feem ntau yog tsim los ntawm qhov ntau thiab tsawg los ntawm NPS 1/2 "mus rau 24". EFW thev naus laus zis ntau yam rau cov kab uas loj heev thiab cov khoom sib txawv xws li cov hlau tsis muaj steel lossis siab - alloy steels (xws li ASTM A671 / A672). EFW tseem tso cai rau kev kho cua sov ntau dua ntawm tag nrho cov yeeb nkab, ua kom cov khoom sib xws hauv cov txheej txheem tseem ceeb ntawm cov kav dej.
Kev Tswjhwm Zoo thiab Kev Ntsuas Cov Qauv
ERW cov kav dej cia siab rau hauv online ultrasonic thiab eddy tam sim no kuaj ntawm forged weld seam. EFW cov kav dej, vim muaj cov hlau muab tub lim, feem ntau yuav tsum tau 100% radiographic (X-ray) tshuaj xyuas kom paub tseeb tias kev nkag mus rau tag nrho thiab tsis muaj qhov tsis xws luag, ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb ntawm siab - siab refineries thiab fais fab nroj tsuag.
Xaiv cov yeeb nkab zoo rau koj qhov project
Qhov kev xaiv nyob ntawm qhov project qhov ntsuas thiab qhov siab. ERW yog tus nqi -kev xaiv zoo rau kev sib kis dav dav, kab dej, thiab cov kav dej. EFW tau teev tseg rau hnyav- phab ntsa txheej txheem piping, loj- nplai refinery mains, thiab cov ntawv thov uas muaj siab -kub los yog corrosive heev media uas qhov siab tshaj plaws weld kev ncaj ncees yog yuav tsum tau.
Cov lus nug nquag nug (FAQ)
1. Puas yog ERW yeeb nkab pheej yig dua EFW yeeb nkab?
Yog lawm, rau tib qhov loj me thiab qib, ERW feem ntau pheej yig dua vim yog qhov siab - ceev automated manufacturing txheej txheem thiab tsis muaj cov nqi hlau muab tub lim.
2. Puas yog ERW yeeb nkab puas muaj qhov pom kev vuam seam?
Niaj hnub nimno ERW kav dej muaj cov seam huv heev uas feem ntau yuav luag tsis pom tom qab tshem tawm sab nraud thiab sab hauv flash thiab cov yeeb nkab yog qhov qub.
3. Cov kav dej EFW puas tuaj yeem siv rau hauv siab -kub boilers?
Yog lawm, EFW cov kav dej ua tau raws li cov qauv zoo li ASTM A671 nquag siv hauv siab -kub, siab - cov kev pabcuam siab qhov chaw loj yuav tsum muaj.
4. Cov qauv zoo li cas rau EFW kav dej?
Cov qauv qauv muaj xws li ASTM A671 thiab A672 rau carbon steel, thiab ASTM A358 rau stainless hlau fusion-welded kav.
5. Txoj kev vuam twg zoo dua rau cov kav dej loj?
EFW (xws li SAW) yog txoj hauv kev zoo tshaj rau cov kav dej loj dua 24 ntiv tes vim nws muab qhov tob ntawm fusion xav tau rau cov phaj tuab.
