Q235 Galvanized Pub kab Hlau Yeeb Nkab Tube

Khoov lub phaj hlau los yog sawb rau hauv qhov yuav tsum tau ua ntu ntu thiab qhov loj me los ntawm ntau txoj kev tsim, ces weld seam kom tau cov yeeb nkab steel.Nws tuaj yeem muab faib ua kauv submerged arc welded yeeb nkab, ncaj seam ob sab submerged arc welded yeeb nkab thiab kuj welded yeeb nkab.

-spiral steel yeeb nkab yog raws li nram no:
Cov ntaub ntawv raw ntawm kauv steel yeeb nkab yog sawb coil, vuam hlau thiab flux.Ua ntej tsim, lub sawb yog leveled, trimmed, npaj, ntxuav thiab thauj rau saum npoo, thiab khoov.Weld gap control device yog siv los xyuas kom meej tias qhov sib txawv weld ua tau raws li qhov xav tau ntawm vuam.Cov yeeb nkab txoj kab uas hla, misalignment thiab weld gap yog nruj me ntsis tswj.Tom qab txiav mus rau hauv ib lub yeeb nkab steel, thawj peb ntawm txhua batch ntawm cov kav hlau steel yuav tsum nruj me ntsis kev tshuaj xyuas thawj zaug, txhawm rau txheeb xyuas cov khoom siv hluav taws xob, tshuaj lom neeg muaj pes tsawg leeg, fusion xeev thiab qhov chaw zoo ntawm cov vuam, thiab los ntawm cov khoom tsis zoo. -kev kuaj xyuas kom ntseeg tau tias cov txheej txheem tsim cov yeeb nkab tsim nyog, nws tuaj yeem raug muab tso rau hauv ntau lawm.

-LSAW tub:
Feem ntau hais lus, LSAW yeeb nkab yog ua los ntawm cov hlau phaj los ntawm cov txheej txheem sib txawv, xws li ob-sided submerged arc vuam thiab nthuav dav tom qab vuam.Cov txheej txheem tsim ntawm LSAW yeeb nkab suav nrog uo (UOE), Rb (RBE), JCO (JCOE), thiab lwm yam.

Kev tsim cov txheej txheem ntawm UOE LSAW yeeb nkab:
Cov txheej txheem tsim ntawm UOE longitudinal submerged arc welded yeeb nkab feem ntau suav nrog peb txoj kev tsim: steel phaj ua ntej khoov, u sib sau thiab O sib sau.Txhua tus txheej txheem siv cov xovxwm tshwj xeeb los ua kom tiav peb cov txheej txheem ntawm steel phaj ntug ua ntej dabtsi yog khoov, u forming thiab O forming thiaj li yuav deform steel phaj rau hauv lub voj voog.Cov txheej txheem tsim ntawm JCOE longitudinal submerged arc welded yeeb nkab: hauv jc0 Tom qab rov stamping ntawm lub tshuab tsim, thawj ib nrab ntawm cov hlau phaj yog nias rau hauv J puab, thiab tom qab ntawd ib nrab ntawm cov hlau phaj yog nias rau hauv J puab. los ua ib daim duab C.

Kev sib piv ntawm JCO thiab uo molding txoj kev:
JCO txoj kev yog kev ua haujlwm siab, uas hloov cov txheej txheem ntawm cov yeeb nkab steel los ntawm ob kauj ruam ntawm UO txoj kev mus rau ntau kauj ruam.Nyob rau hauv txoj kev tsim, cov hlau phaj muaj cov yam ntxwv deformation, me me residual kev nyuaj siab thiab tsis muaj khawb ntawm qhov chaw.Cov txheej txheem steel yeeb nkab muaj qhov yooj yim ntawm qhov loj ntawm txoj kab uas hla thiab phab ntsa thickness.Nws tuaj yeem tsim cov khoom loj thiab cov khoom me me, nrog rau cov khoom loj thiab cov khoom zoo Nws tseem tuaj yeem tsim cov kab me me thiab cov kav hlau loj, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov kav dej tuab tuab, tshwj xeeb tshaj yog nyob rau hauv cov kav dej. kev tsim cov kav dej nruab nrab thiab me me tuab tuab phab ntsa.Nws muaj qhov zoo sib xws ntawm lwm cov txheej txheem, thiab tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv ntau rau cov yeeb nkab steel specifications.Uo molding adopts u thiab O ob-kauj ruam siab txoj kev, uas yog yus muaj los ntawm loj muaj peev xwm thiab siab tso zis ntau lawm.Feem ntau, cov zis txhua xyoo tuaj yeem ncav cuag 30-30% 1 lab tons, tsim nyog rau ib qho tshwj xeeb ntau lawm.

- Ncaj seam siab zaus welded yeeb nkab:
Qhov ncaj seam siab zaus welded yeeb nkab (ERW) yog tsim los ntawm cua sov ntawm ntug ntawm lub raj billet nrog cov nyhuv ntawm daim tawv nqaij thiab cov nyhuv sib thooj ntawm lub siab zaus tam sim no tom qab kub dov kauj yog zoo li lub tshuab tsim, thiab tom qab ntawd siab vuam yog nqa tawm. nyob rau hauv qhov kev txiav txim ntawm extrusion roller.
