Lub welded steel yeeb nkab kuj hu ua welded yeeb nkab. Nws yog cov yeeb nkab steel ua los ntawm steel phaj lossis steel siv thiab welded tom qab curling. Vuam steel yeeb nkab ntau lawm tshuab yog yooj yim, siab ntau lawm efficiency, ntau ntau yam specifications, thiab cov khoom me me, tab sis feem ntau qis dua seamless steel kav. Txij li thaum xyoo 1930, nrog rau kev txhim kho sai ntawm cov hlau zoo thiab cov hlau dov ntau lawm thiab kev nce qib ntawm vuam thiab tshuaj xyuas tshuab, qhov zoo ntawm welds tau raug txhim kho tas li. Slim steel tube. welding steel yeeb nkab yog muab faib ua ncaj seam welded kav thiab kauv welded kav nyob rau hauv daim ntawv ntawm welds.
Cov txheej txheem ntau lawm ntawm txoj hlua khi ncaj yog qhov yooj yim, kev ua haujlwm siab ntau lawm, tus nqi qis, thiab kev loj hlob sai. Lub zog ntawm cov kauv raj feem ntau yog siab tshaj qhov ncaj seam welded yeeb nkab. Nws tuaj yeem siv cov yeeb nkab welded nrog ib txoj kab uas loj dua ntawm cov khoom siv billet, thiab tseem tuaj yeem siv tib qhov dav los tsim ib lub raj nrog cov kav dej sib txawv nrog cov kav dej sib txawv. Txawm li cas los xij, piv nrog tib qhov ntev ntawm tib qhov ntev, qhov ntev ntawm qhov vuam yog nce los ntawm 30 ~ 100%, thiab qhov ceev ntau lawm yog qis dua. Yog li ntawd, feem ntau ntawm cov me me-caliber welded kav yog welded nrog ncaj seams, thiab feem ntau ntawm cov loj-caliber welded kav yog feem ntau muab kauv welded.
1. Tsawg-voltage kua conveyor ncaj seam vuam steel yeeb nkab (GB / T 3092-2008) kuj hu ua cov kav dej dav dav, feem ntau hu ua cov kav dej dub. Nws yog welded steel yeeb nkab uas yog siv los thauj dej, roj, cua, roj, thiab cua sov. Cov kav hlau tau muab faib ua cov kav hlau zoo tib yam thiab cov kav hlau tuab. Cov kev qhia tshwj xeeb ntawm cov yeeb nkab steel yog qhia nyob rau hauv nominal caliber (MM), thiab lub nominal txoj kab uas hla yog kwv yees tus nqi ntawm lub puab kab. Nws yog feem ntau siv hauv nti, xws li 11/2. Vuam steel kav rau qis-voltage kua conveying yog siv ncaj qha mus thauj cov kua, thiab lawv kuj tseem siv raws li cov thawj tube rau vuam steel kav nrog galvanized vuam steel yeeb nkab rau low-voltage fluid thauj.
2. Tsawg-voltage kua conveyor vuam steel yeeb nkab (GB / T 3091-2015) kuj hu ua galvanized vuam steel yeeb nkab, feem ntau hu ua cov yeeb nkab dawb. Nws yog siv los thauj dej, roj, roj cua, cua sov chav, dej sov, thiab lwm yam., xws li cov dej tsis tshua muaj siab lossis lwm yam kev siv kub-dip galvanized vuam (lub qhov cub vuam lossis vuam) steel yeeb nkab. Lub thickness ntawm cov yeeb nkab steel yog muab faib ua cov kav dej zoo tib yam galvanized steel kav thiab cov kav dej tuab galvanized steel kav. Cov kev qhia tshwj xeeb ntawm cov yeeb nkab steel yog qhia nyob rau hauv nominal caliber (MM), thiab lub nominal txoj kab uas hla yog kwv yees tus nqi ntawm lub puab kab. Nws yog feem ntau siv hauv nti, xws li 11/2.
3. Ordinary carbon steel hlau casing (GB 3640-88) yog cov yeeb nkab steel siv los tiv thaiv cov xov hlau hauv cov khoom siv hluav taws xob xws li cov tsev lag luam thiab cov pej xeem, kev teeb tsa cov tshuab thiab cov khoom siv.
4. Ncaj seam welded steel yeeb nkab (GB / T 13793-2016) yog cov yeeb nkab steel nrog longitudinal parallel welds thiab steel kav. Nws feem ntau yog muab faib ua pej xeem welding steel kav, vuam nyias phab ntsa kav, transformer txias roj kav, thiab hais txog.
5. Cov kua dej siab conveyor siv cov kauv sib koom ua ke faus arc welded steel kav (SY 5036-83) yog siv los ua ib lub raj dawb nrog kub dov steel siv. Spiral sewing steel yeeb nkab. Cov yeeb nkab steel muaj lub zog siab thiab kev ua haujlwm zoo vuam. Tom qab ntau yam kev soj ntsuam nruj thiab kev sim, kev siv yog kev nyab xeeb thiab txhim khu kev qha. Cov yeeb nkab steel muaj qhov loj caliber, siab conveying efficiency, thiab tuaj yeem txuag peev hauv cov kav xa dej. Nws yog tsuas yog siv los thauj cov kav dej rau cov roj av thiab cov nkev ntuj.
6. Lub siab ua kua conveyor kauv seam high-frequency welding steel yeeb nkab (SY 5038-83) yog siv los ua ib lub raj dawb nrog kub dov steel siv. Delled kauv seam high-frequency vuam steel yeeb nkab. Cov yeeb nkab steel muaj lub zog siab thiab zoo plasticity, uas yooj yim rau vuam thiab ua. Tom qab ntau yam nruj thiab kev soj ntsuam thiab kev sim, kev siv kev nyab xeeb thiab txhim khu kev qha, loj-scale steel yeeb nkab caliber, siab conversion efficiency, thiab txuag pipeline peev. Nws yog tsuas yog siv los nteg cov kav dej uas thauj cov roj av, cov nkev roj, thiab lwm yam.
7. Feem ntau, low-voltage fluid conveyor for spiral joints (SY5037-83) yog siv los ua ib lub raj khoob nrog kub dov steel siv. Nws feem ntau yog ua los ntawm cov kauv sov. Dej, roj, cua, thiab chav dej dav dav uas tsis tshua muaj hluav taws xob siv hluav taws xob siv faus arc vuam steel kav.
8. Feem ntau, kev hloov pauv cov kua hluav taws xob qis rau cov khoom siv hluav taws xob sib xyaw ua haujlwm siab welding steel yeeb nkab (SY 5039-83) yog siv los ua ib lub raj dawb nrog kub dov steel siv. Kauv seam high-frequency vuam steel yeeb nkab.
9. Cov pawg uas muaj kauv welded steel yeeb nkab (SY 5040-83) yog siv los ua lub raj khoob nrog kub dov steel siv. Nws feem ntau yog ua los ntawm cov spirals sov thiab yog ua los ntawm ob-sided faus arc vuam los yog high-frequency welding. Cov pawg hauv paus xws li docks thiab txuas hniav.
