Dab tsi yog qhov txawv ntawm kev tsim cov txheej txheem ntawm ncaj seam welded yeeb nkab thiab seamless yeeb nkab?
Seamless yeeb nkab yog tsim los ntawm stamping ib tug steel billet rau hauv lub hollow raj, thaumncaj seam welded yeeb nkabyog tsim los ntawm dov steel daim hlau los yog strips rau hauv lub tog raj kheej thiab ces welding longitudinal welds.
Cov qauv dab tsi ua ASTM A500 structural ncaj seam welded kav ua raws li qhov ntev thiab kam rau ua?
ASTM A500 cov kav dej ua haujlwmUa raws li cov qauv tshwj xeeb thiab qhov ntev ntev tau teev tseg hauv ASTM A500 / A500M-2023, uas qhia meej txog kev sib txawv ntawm cov kab uas hla, phab ntsa thickness, ncaj, sab perpendicularity, fillet radius, thiab torsion.
Dab tsi yog qhov tseem ceeb tshaj plaws thaum xaiv A500 steel yeeb nkab?
Qhov tseem ceeb tshaj plaws kev txiav txim siab thaum xaivA500 steel yeeb nkabyog txuam nws rau qhov tshwj xeeb qhov yuav tsum tau ua. Qhov no suav nrog kev ntsuam xyuas lub zog, durability, thiab qhov tseeb ntawm qhov yuav tsum tau siv rau kev siv. Piv txwv li, cov txheej txheem thav duab lossis cov txuas hniav yuav xav tau ntau dua - cov kav hlau steel kom muaj zog, thaum lwm cov ntawv thov tuaj yeem ua qhov tseem ceeb dua qhov kev tiv thaiv kom ruaj khov kom haum thiab ruaj khov.
Kev tiv thaiv xeb dab tsi feem ntau yog siv rau ASTM A500 cov qauv ncaj seam welded steel kav?
Kev tiv thaiv xeb feem ntau rauASTM A500 steel yeeb nkabsuav nrog galvanizing (kub-dip galvanizing thiab electro-galvanizing), pleev xim, hmoov txheej, thiab ntau yam txheej tshwj xeeb, xws li peb- txheej polyethylene (3LPE). Ua ntej txheej, steel yeeb nkab nto feem ntau yog ntxuav los yog sandblasted kom tshem tawm cov xeb uas twb muaj lawm thiab npaj qhov chaw.
Cov qauv tsev twg yog ASTM A500 structural ncaj seam welded steel kav feem ntau siv hauv?
ASTM A500 structural ncaj seam welded steel kavfeem ntau yog siv rau hauv kev tsim vaj tse rau thav duab, txhawb nqa kab thiab kab, nrog rau cov kev tsim kho vaj tse xws li txuas hniav thiab railings. Lawv kuj tau siv rau hauv kev lag luam infrastructure, tsheb thauj mus los, thiab kev tsim cov khoom siv hnyav thiab tshuab.
