Galvanized steel yeeb nkab specification qauv luj rooj
Cov lus qhia qhov hnyav ntawm cov kav dej galvanized yog siv raws li GB / T3091-2001 tus qauv. Lub luj lub rooj ntawm specifications thiab qauv yog raws li nram no:
Nominal puab txoj kab uas hla DN15: txheej inch 21.3mm, phab ntsa thickness 2.8mm, yam tsawg kawg nkaus phab ntsa thickness 2.45mm, meter hnyav 1.28kg, hauv paus luj 7.68kg (welded yeeb nkab); meter hnyav 1.35kg, hauv paus hnyav 8.14kg (galvanized yeeb nkab). 123
Nominal puab txoj kab uas hla DN20: txheej inch 26.9mm, phab ntsa thickness 2.8mm, yam tsawg kawg nkaus phab ntsa thickness 2.45mm, meter hnyav 1.66kg, hauv paus luj 9.96kg (welded yeeb nkab); 'meter' hnyav 1.76kg, hauv paus hnyav 10.56kg (galvanized yeeb nkab).
Los ntawm kev sib piv, qhov hnyav ntawm qhov tshwj xeeb thiab cov qauv ntawm galvanized steel kav nrog lwm cov nominal puab diameters tuaj yeem tau txais.
Tsis tas li ntawd, cov qauv ntsuas qhov hnyav ntawm galvanized steel yeeb nkab yog: [(sab nraud txoj kab uas hla-phab ntsa thickness) * phab ntsa thickness]* 0 02466=kg / meter (qhov hnyav ib meter)
Sib nrug ntawm qhov no, muaj lwm hom galvanized kav nrog cov hauv qab no specifications thiab hnyav:
Q195 galvanized yeeb nkab: sab nraud txoj kab uas hla 21.3mm, phab ntsa thickness 2.0mm, ib leeg yeeb nkab nrog qhov ntev ntawm 6m hnyav txog 3.38kg; sab nraud txoj kab uas hla 48mm, phab ntsa thickness 2.75mm, ib leeg yeeb nkab nrog qhov ntev ntawm 6m hnyav txog 8.16kg. 4
Q235 galvanized yeeb nkab: sab nraud txoj kab uas hla 33.4mm, phab ntsa thickness 3.25mm, ib leeg yeeb nkab nrog qhov ntev ntawm 6m hnyav txog 8.21kg; sab nraud txoj kab uas hla 60.3 hli, phab ntsa thickness 3.6 hli, ib leeg yeeb nkab nrog ib tug ntev ntawm 6m nyhav txog 18.05kg.
Txij li cov specifications thiab hnyav ntawm galvanized steel kav yuav txawv nyob ntawm seb cov chaw tsim khoom thiab cov txheej txheem, cov specifications thiab hnyav yuav tsum tau raws li cov khoom tiag.
