1. Tsawg-voltage kua conveyor ncaj seam welded steel yeeb nkab (GB / T 3092-1993) kuj hu ua cov kav dej ncaj seam steel kav, feem ntau hu ua cov kav dej dub. Welded steel kav yog siv los thauj dej, roj, huab cua, roj, thiab cov cua kub cua uas tsis tshua muaj siab. Cov yeeb nkab steel tau muab faib ua cov yeeb nkab steel thiab cov yeeb nkab tuab, thiab cov yeeb nkab kawg tau muab faib ua cov yeeb nkab uas tsis yog-threaded thiab steel yeeb nkab (cov kav dej du) thiab cov yeeb nkab steel. Thaum lub specification steel yeeb nkab paub rau pej xeem txoj kab uas hla (MM), lub nominal txoj kab uas hla yog kwv yees li txoj kab uas hla. Feem ntau siv ntiv tes, xws li 11x2. Vuam steel kav yog siv rau kev thauj mus los ntawm cov kua dej uas tsis tshua muaj hluav taws xob, uas tsis yog siv los thauj cov kua dej ncaj qha xwb, tab sis kuj tseem yog cov kav dej qub ntawm cov kav dej galvanized vuam steel kav uas tuaj yeem siv rau kev thauj mus los ntawm cov kua dej tsawg-voltage.
2. Galvanized ncaj seam welded steel yeeb nkab (GB / T 3091-1993) yog siv rau cov kua dej uas tsis muaj hluav taws xob, tseem hu ua galvanized vuam ncaj seam vuam steel kav, feem ntau hu ua cov kav dej dawb. Nws yog siv los thauj dej, roj, cua, roj, roj, thiab cua sov. Chav dej, dej sov, thiab lwm yam. Feem ntau siv cov kua dej ua haujlwm qis lossis lwm cov kav dej steel nrog kub-dip galvanized vuam (lub qhov cub vuam lossis hluav taws xob vuam). Cov phab ntsa tuab ntawm cov yeeb nkab steel yog muab faib ua cov hlau zoo tib yam galvanized thiab tuab galvanized steel daim hlau. Cov yeeb nkab uas tsis yog threaded kawg yog muab tso rau hauv threaded galvanized steel thiab galvanized hlau. Thaum lub specification steel yeeb nkab paub rau pej xeem txoj kab uas hla (MM), lub nominal txoj kab uas hla yog kwv yees li txoj kab uas hla. Feem ntau siv ntiv tes, xws li 11x2.
3. Ordinary carbon steel lub tes tsho (GB3640-88) yog cov yeeb nkab txuas ncaj qha uas siv rau hauv kev teeb tsa ntawm cov tshuab hluav taws xob thiab cov khoom siv xws li cov tsev lag luam thiab pej xeem, kev teeb tsa, thiab lwm yam los tiv thaiv cov xov hlau.
4. Direct seam welding rau steel kav (YB 242-63) yog ib tug ncaj welding steel yeeb nkab uas parallel nrog steel kav nrog longitudinal kev tshawb fawb. Feem ntau nws tuaj yeem muab faib ua vuam ncaj seam steel kav, vuam nyias-walled ncaj seam kav, transformer txias roj ncaj seam kav, thiab lwm yam.
5. Cov kua dej siab conveyor kauv arc vuam ncaj seam steel yeeb nkab (SY5036-83) yog cov yeeb nkab kub-kuav los tiag steel yeeb nkab ua lub plhaub plhaub. Nws yog feem ntau tsim nyob rau hauv ib tug tej yam kub thiab siv ob-sided arc vuam txoj kev thiab siab kua rau dej nyab. Cov kav hlau steel muaj lub siab muaj zog thiab cov khoom siv vuam zoo.
6. Lub siab ua kua conveyor kauv high-frequency welding steel yeeb nkab (SY5038-83) yog ib tug high-frequency vuam steel raj kauv. Thaum lub sij hawm overlapping high-frequency welding txheej txheem, nws yog feem ntau siv raws li ib tug kub dov raj. Cov kav hlau muaj lub zog siab, zoo plasticity, thiab vuam tshuab ua tau yooj yim. Tom qab ntau yam kev soj ntsuam nruj thiab kev sim, kev siv kev nyab xeeb thiab kev ntseeg siab, loj steel yeeb nkab txoj kab uas hla, thiab kev thauj mus los siab tuaj yeem txuag peev hauv cov kav dej. Nws yog tsuas yog siv rau tso cov roj thiab cov roj av thauj mus los.
7. Siv los ua cov kua dej ua haujlwm qis (SY5037-83) los ntawm cov pob qij txha uas thauj los ntawm kev thauj mus los. faus arc vuam steel yeeb nkab. Nws yog faus arc vuam steel yeeb nkab uas siv tau rau dej, roj, thiab cua.
8. Feem ntau cov spiral seam high-frequency welding steel yeeb nkab (SY5039-83) lub raj xa los ntawm low-voltage streaming yog tsim los ntawm kub dov steel phaj ntawm chav tsev kub. Txoj kev siv vuam ntau zaus siv kauv txuas zaus vuam steel yeeb nkab feem ntau kis tau.
9. Cov pawg nrog cov kav hlau txuas txuas (SY5040-83) yog ua raws li lub raj xa hluav taws xob los ntawm lub raj kub dov steel. Cov qauv, chaw nres nkoj, choj thiab lwm yam hauv paus pawg.
Cov txheej txheem ntau lawm ntawm cov kav dej ncaj nraim yog qhov yooj yim, kev ua haujlwm siab, tus nqi qis, thiab kev loj hlob sai. Cov kav dej kauv feem ntau yog ntau dua li qhov ntev ntawm lub zog. Lub welded yeeb nkab nrog ib txoj kab uas loj loj tuaj yeem ua tau nrog lub voj voog nqaim, thiab cov kav dej welded nrog cov yeeb nkab sib txawv tuaj yeem tsim tau ntawm tib qhov dav dav. Txawm li cas los xij, ntev npaum li nws tau muab piv nrog cov hlua ncaj nraim, qhov ntev ntawm cov vuam yog nce los ntawm 30% thiab 100%, txo cov khoom tsim tau.
Yog li ntawd, feem ntau ntawm cov me me txoj kab uas hla welded kav siv ncaj seam welding, thiab feem ntau ntawm cov loj-caliber welded kav yuav welded.
