Muaj 4 hom welded steel kav rau cov kua dej uas tsis tshua muaj siab
1. Welded steel kav rau kev thauj mus los ntawm cov kua dej qis (GB/T3092-1993) kuj hu ua cov kav dej dav dav, feem ntau hu ua cov kav dej dub. Lawv yog cov welded steel kav siv los thauj cov dej uas tsis tshua muaj siab xws li dej, roj, cua, roj thiab cua sov chav thiab lwm yam. Cov phab ntsa tuab ntawm cov yeeb nkab steel yog muab faib ua cov kav hlau zoo tib yam thiab cov kav hlau tuab tuab; cov yeeb nkab kawg daim ntawv tau muab faib ua cov kav hlau tsis muaj xov hlau (cov kav dej dawb) thiab cov kav hlau threaded. Cov kev qhia tshwj xeeb ntawm cov yeeb nkab steel yog qhia nyob rau hauv nominal txoj kab uas hla (mm), uas yog kwv yees tus nqi ntawm lub puab kab. Nws yog feem ntau qhia hauv nti, xws li 11/2. Ntxiv nrog rau kev siv ncaj qha los thauj cov kua dej, welded steel kav rau kev thauj mus los ntawm cov dej tsis tshua muaj siab kuj tau siv dav raws li cov kav dej qub ntawm cov kav dej galvanized welded steel kav rau kev thauj cov kua dej tsawg.
2. Galvanized welded steel kav rau kev thauj mus los tsis tshua muaj siab (GB / T3091-1993) kuj hu ua galvanized electric welded steel kav, feem ntau hu ua cov kav dej dawb. Nws yog kub-dip galvanized welded (lub qhov cub vuam lossis hluav taws xob vuam) cov yeeb nkab steel siv rau kev xa dej, roj, cua, roj, cua sov chav, dej sov thiab lwm yam dej uas tsis tshua muaj siab lossis lwm lub hom phiaj. Cov phab ntsa tuab ntawm cov yeeb nkab steel yog muab faib ua cov yeeb nkab zoo tib yam galvanized steel yeeb nkab thiab thickened galvanized steel yeeb nkab; cov yeeb nkab kawg daim ntawv muab faib ua cov yeeb nkab uas tsis yog threaded galvanized steel yeeb nkab thiab threaded galvanized steel yeeb nkab. Cov specifications ntawm cov yeeb nkab steel yog qhia nyob rau hauv nominal txoj kab uas hla (mm), thiab lub nominal txoj kab uas hla yog kwv yees tus nqi ntawm lub puab txoj kab uas hla. Nws yog feem ntau qhia hauv nti, xws li 11/2, thiab lwm yam.
3. Kauv seam submerged arc welded steel yeeb nkab rau kev thauj mus los ntawm cov dej tsis tshua muaj siab (SY5037-83) yog ua los ntawm kub dov steel strip coil li yeeb nkab dawb paug, muab kauv tsim nyob rau hauv chav tsev kub, thiab ua los ntawm ob sab tsis siv neeg. submerged arc welding los yog ib txoj kev welding. Nws yog siv rau dej, roj, huab cua thiab chav thiab lwm yam kev thauj mus los ntawm cov dej uas tsis tshua muaj siab. Submerged arc welded steel yeeb nkab.
4. Kauv seam high-frequency welded steel yeeb nkab rau kev thauj mus los ntawm cov dej tsis tshua muaj siab (SY5039-83) yog ua los ntawm kub dov steel strip coil li lub raj khoob, muab kauv tsim nyob rau hauv chav tsev kub, thiab welded los ntawm high- zaus lap welding. Nws yog siv rau kauv seam high-frequency welded steel yeeb nkab rau kev thauj mus los ntawm cov dej tsis tshua muaj siab.
