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.Welding steel yeeb nkab ntau lawm tshuab yog yooj yim, siab ntau lawm efficiency, ntau yam specifications, thiab cov khoom me me, tab sis feem ntau qis dua seamless steel kav.Txij li xyoo 1930s, Nrog rau txoj kev loj hlob sai ntawm high-quality steel thiab steel dov ntau lawm thiab kev nce qib ntawm vuam thiab tshuaj ntsuam xyuas tshuab, qhov zoo ntawm welds tau raug txhim kho tsis tu ncua.Slim steel tube.Qhov vuam 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 cov kav hlau ncaj ncaj yog qhov yooj yim, kev ua haujlwm siab ntau lawm, tus nqi qis, thiab kev loj hlob sai.Lub zog ntawm cov kav raj yog feem ntau siab dua 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 sib txawv welded kav nrog cov yeeb nkab steel sib txawv.Txawm li cas los xij, piv nrog qhov ntev ntawm tib qhov ntev, qhov ntev. ntawm cov welded yog nce los ntawm 30 ~ 100%, thiab ntau lawm ceev 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 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. huab cua, roj, thiab cua sov chav.Steel kav tau muab faib ua cov kav hlau zoo tib yam thiab cov kav hlau tuab.Qhov tshwj xeeb ntawm cov yeeb nkab steel yog qhia nyob rau hauv nominal caliber (MM), thiab lub nominal caliber yog kwv yees tus nqi ntawm lub puab txoj kab uas hla. Nws yog feem ntau siv rau hauv nti, xws li 11/2.Welding steel kav rau qis-voltage fluid conveying yog siv ncaj qha los thauj cov kua, thiab lawv kuj tseem siv los ua cov raj qub rau vuam steel kav nrog galvanized vuam steel yeeb nkab rau qis - kev thauj mus los ntawm cov kua dej voltage.
2. Tsawg-voltage fluid conveyor welding 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 sov, dej sov, thiab lwm yam, xws li cov kua dej tsis tshua muaj siab lossis lwm yam kev siv kub-dip galvanized vuam (lub qhov cub vuam lossis vuam) steel yeeb nkab.Qhov tuab 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. ntawm cov yeeb nkab steel yog qhia nyob rau hauv nominal caliber (MM), thiab lub nominal caliber yog kwv yees tus nqi ntawm lub puab txoj kab uas hla.Nws yog feem ntau siv nyob rau 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. yog li ntawd.
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 khoob nrog kub-kuav los tiag steel siv.Spiral sewing steel yeeb nkab.The steel yeeb nkab muaj zog siab thiab zoo vuam kev ua tau zoo. . Tom qab ntau yam kev soj ntsuam nruj nruj thiab kev sim, kev siv yog kev nyab xeeb thiab txhim khu kev qha.Cov yeeb nkab steel muaj qhov loj me, siab conveying efficiency, thiab tuaj yeem txuag peev hauv cov kav xa dej.
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.Pulling kauv seam high-frequency vuam steel yeeb nkab.Cov yeeb nkab steel muaj lub zog siab. thiab zoo plasticity, uas yog yooj yim rau vuam thiab ua. Tom qab ntau yam nruj thiab kev sim thiab kev sim, kev siv kev nyab xeeb thiab kev ntseeg siab, loj-scale steel yeeb nkab caliber, siab conversion efficiency, thiab txuag pipeline peev.Nws yog tsuas yog siv los nteg pipelines uas thauj roj, natural gas, 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 kav dej sov. Dej, roj, cua, thiab chav dav dav uas tsis tshua muaj hluav taws xob ua kua conveyor siv faus arc vuam steel kav.
8. Feem ntau, kev hloov pauv ntawm cov kua dej qis qis rau cov kauv seam high-frequency welding steel yeeb nkab (SY 5039-83) yog siv los ua ib lub raj khoob nrog kub-kuav los tiag steel siv.Spiral 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 tog faus arc vuam los yog high-frequency welding.Basic pawg xws li docks thiab txuas hniav.
