Uluhlu lobungakanani be-ASTM A501
Ukwahlulwahlulwa kwamaBanga
I-ASTM A501 yahlulwe yangamanqanaba amathathu, iBanga A, iBanga B, kunye neBanga C.
IiMilo zeCandelo elingenanto
Iimilo ezisikwere, ezingqukuva, ezizinxantathu, okanye ezikhethekileyo.
Iimpahla ezingekasilwa
Intsimbi mayibe yenziwe ngenkqubo yokwenza intsimbi esebenzisa ioksijini esisiseko okanye i-electric-arc-furnace.
Intsimbi inokwenziwa ngee-ingots okanye yenziwe ngentambo.
Iinkqubo zoMveliso
Ityhubhu kufuneka yenziwe ngenye yezi nkqubo zilandelayo:ingenamthungoukuwelda ngesitovu-isiqu (ukuwelda okuqhubekayo);ukuwelda kokumelana nombane (ERW)okanye ukuwelda kwe-arc engaphantsi komhlaba (i-SAW) kulandele ukufudumeza kwakhona kulo lonke icandelo elinqamlezileyo kunye nokwenza ubushushu ngenkqubo yokunciphisa okanye yokubumba, okanye zombini.
Ukwakheka kokugqibela kwesimo kufuneka kwenziwe ngenkqubo yokwakheka eshushu.
Kuya kuvunyelwa ukongeza unyango lobushushu oluqhelekileyo kwiityhubhu ezinobukhulu bodonga obungaphezulu kwe-13mm [1/2 intshi].
Ukwakheka kweekhemikhali ze-ASTM A501
Indlela yoVavanyo: ASTM A751.
Kwimigangatho ye-ASTM A501, kukho iindlela ezimbini zokuhlalutya ukwakheka kweekhemikhali zentsimbi: uhlalutyo lobushushu kunye nohlalutyo lwemveliso.
Uhlalutyo lobushushu lwenziwa ngexesha lenkqubo yokunyibilikisa intsimbi. Injongo yalo kukuqinisekisa ukuba ukwakheka kweekhemikhali zentsimbi kuyahlangabezana neemfuno zomgangatho othile.
Uhlalutyo lwemveliso, kwelinye icala, lwenziwa emva kokuba intsimbi sele yenziwe imveliso. Le ndlela yohlalutyo isetyenziselwa ukuqinisekisa ukuba ulwakhiwo lweekhemikhali lwemveliso yokugqibela luyahlangabezana neemfuno ezichaziweyo.
Iipropati zoomatshini ze-ASTM A501
Iindlela zovavanyo kunye neenkcazo ziyahambelana neemfuno ezifanelekileyo ze-ASTM A370.
Ubukhulu bodonga obuyi-≤ 6.3mm [0.25in] abufuni vavanyo lokuchaphazela.
Ukunyamezelana kwe-ASTM A501 ngokwemilinganiselo
Ukugaya nge-galvanizing
Ukuze iityhubhu zesakhiwo zibe zi-hot-dip galvanized, olu phawu kufuneka luhlangabezane neemfuno zeSpecial A53/A53M.
Linganisa ixabiso lengubo engaphandle kombhobho ukuze ubone ubunzima/ubukhulu bengubo.
Inkangeleko
Iityhubhu zesakhiwo mazingabi naziphene kwaye zibe nomphezulu ogudileyo ngexesha lokwenziwa kwe-hot rolling.
Iziphene zomphezulu ziya kuhlelwa ngolu hlobo xa ubunzulu beziphene zomphezulu budlula i-10% yobukhulu bodonga obuqhelekileyo.
Iziphene ezifuna ukulungiswa mazisuswe ngokupheleleyo ngokusika okanye ngokusila ngaphambi kokuba zifakwe kwi-welding.
Ukumakisha
Uphawu lwe-ASTM A501 kufuneka lube nolwazi olulandelayo ubuncinane:
Igama lomenzi
Uphawu okanye uphawu lwentengiso
Ubungakanani
Igama lomgangatho (unyaka wokupapashwa awufuneki)
Ibanga
Ubude ngabunye bombhobho wolwakhiwo kufuneka buphawulwe ngendlela efanelekileyo, efana nokuqengqeleka, ukunyathela, ukunyathela, okanye ukupeyinta.
Kwiityhubhu zesakhiwo ezingaphantsi kwama-50 mm [2 in] OD, kuvumelekile ukuphawula ulwazi lwentsimbi kwileyibhile eqhotyoshelwe kwiphakheji nganye.
