Yuav ua li cas paub qhov txawv ERW, LSAW, SSAW, thiab SMLS:
Kev Txhais Tes thiab Tsim Tsim Kev Tsim
-Txoj (Loj zaus Kuj Welded Yeeb Nkab): Kub Rolled Steel Sawb yog siv los ua cov khoom siv raw. Tom qab ntau cov txheej txheem, kev tiv thaiv tshav kub yog siv hauv cov hluav taws xob ntau dua hluav taws xob rau kom yaj thiab crystallize cov hlau ntawm cov yeeb nkab los ua ke.
- LSAWW (ncaj zig submerged arc vuam yeeb nkab): kub-rolled steel phaj yog siv ua cov khoom siv raw. Tom qab sib tw ua ntej thiab sib sau ua ke, muab ob sab nrauv submerged arc vuam txheej txheem yog saws. Nyob rau hauv cov txheej txheem vuam, Weld yog them los ntawm ib txheej ntawm glux glux los ua tus weld siab.
- SSAW (Kauv Seam Submerged Arc Vuam Yeeb Nkab): Tib yam li LSAWAS, tab sis submerly arced, tab sis submered arc vuam yog cov thawj lub sij hawm tsim khoom thiab welded los ua ib tug kauv weld.
- smls (seamless steel yeeb nkab): ua los ntawm cov txheej txheem kub, txias yob, tag nrho lub cev, tag nrho raj drawer lub cev tsis muaj weld, yog ib qho yeeb nkab sib tw, yog ib qho yeeb nkab sib tw.
Loj npaum li cas
- ERW: Feem ntau haum rau cov hlab me me, qhov siab tshaj plaws ntawm txoj kab feem ntau tsis ntau tshaj 660MM.
- LSAW: Tsim nyog rau txoj kab uas hla loj loj, feem ntau yog thaum 406mm thiab 1500mm hauv lub taub.
- SSAW: Cov kav dej loj dua tuaj yeem tsim tawm, xws li ntawm 406mm txog 2540mm hauv lub taub.
SMLS: Ntau yam ntawm cov ntau thiab tsawg, los ntawm cov leeg me me tsawg dua 1/8 nti hauv cov tubes 24 nti thiab loj dua.
Cov yam ntxwv ua tau zoo
- ERW: Muaj tus nqi siab dua, zoo dua qhov raug thiab phab ntsa thickness uniformity, tab sis lub zog qis dua thiab lub siab tsis kam dua li sms.
- LSAWW: Muaj lub zog siab thiab kev ua kom zoo, cov yas thiab corrosion tsis kam, siab rau kev kub siab conveying.
- SSAW: zoo ib yam li lsaw ua tau zoo, tab sis vim tias ntawm cov kauv weld, nws tuaj yeem zoo dua cov kev ntxhov siab thaum muaj kev ntxhov siab, thiab tib lub siab hlau txaij tuaj yeem tsim cov khoom uas hla ntawm cov kav hlau.
- SMLS: Muaj lub zog siab, zoo heev siab thiab corrosion tsis kam, vim tias tsis muaj kev sib tw weld, tsim nyog rau kev muaj zog, siab corrosion ib puag ncig.
Daim Ntawv Thov Teb
-Txoj kev siv: feem ntau siv rau dej thiab roj tsheb thauj mus los thiab cov hom phiaj zoo li cov tsheb thauj mus los hauv nroog.
- LSAWW: Nws yog tsuas yog siv rau cov roj ntev ntev thiab roj kev sib kis, tshwj xeeb tshaj yog nyob rau ib puag ncig ib puag ncig xws li Plavental, thiab hauv nroog tuab.
- Txawm li cas los xij: nws tseem siv tau hauv cov roj thiab roj tsheb thauj mus los, tsheb thauj khoom, tab sis nws tsuas yog txwv weld, thiab nws txwv tsis pub muaj qee yam kev xav tau.
- SMLS: Siv dav hauv roj av, tshuaj, roj tsheb, boiler, nuclear, nuclear zog thiab kev lag luam siab thiab corrosion tsis kam.
