IBakala B neBakala C ngamabakala amabini ahlukeneyo aphantsi komgangatho we-ASTM A500.
ASTM A500ngumgangatho ophuhliswe yi-ASTM International ukwenzela ukubanda okudityanisiweyo kunye ne-carbon steel structural tubing engenamthungo.
Okulandelayo, masizithelekise kwaye sizithelekise ngeendlela ezahlukeneyo ukuze siqonde ukuba zeziphi na ukufana nomahluko abanazo.
Umahluko
I-ASTM A500 yeBanga B kunye ne-C ihluke kakhulu ekubunjweni kweekhemikhali, iipropati ezithintekayo, kunye neendawo zokusebenzisa.
Umahluko kuNxibelelwano lweMichiza
Kwinqanaba le-ASTM A500, kukho iindlela ezimbini zokuhlalutya ukwakheka kweekhemikhali zensimbi: uhlalutyo lwe-thermal kunye nohlalutyo lwemveliso.
Uhlalutyo lwe-thermal lwenziwa ngexesha lokunyibilika kwentsimbi.Injongo yalo kukuqinisekisa ukuba ukubunjwa kweekhemikhali zensimbi kuhlangabezana neemfuno zomgangatho othile.
Uhlalutyo lwemveliso, ngakolunye uhlangothi, lwenziwa emva kokuba intsimbi sele yenziwe imveliso.Le ndlela yokuhlalutya isetyenziselwa ukuqinisekisa ukuba ukubunjwa kweekhemikhali zemveliso yokugqibela ihlangabezana neemfuno ezichaziweyo.
Akumangalisi ukuba umxholo wekhabhoni weBanga C ungaphantsi kancinane kuneBanga B, nto leyo enokuthetha ukuba iBanga C linokuqina okungcono xa udibanisa kunye nokubumba.
Umahluko kwiiPropati zeTensile
IBanga B: Ngokuqhelekileyo inomlinganiselo ophezulu we-ductility, evumela ukuba yandise kwi-tension ngaphandle kokuphulwa, kwaye ifanelekile kwizakhiwo ezifuna ukugoba okanye ukuguqulwa.
IBanga C: Inokuqina okuphezulu kunye namandla esivuno ngenxa yokwakheka kweekhemikhali, kodwa inokuba nganeno kancinci kuneBanga B.
Umahluko kwiSicelo
Nangona zombini zisetyenziselwa izicelo zesakhiwo kunye nenkxaso, ugxininiso luhlukile.
IBanga B: Ngenxa ye-welding yayo engcono kunye neempawu zokwenza, isetyenziswa rhoqo kwizakhiwo zokwakha, ukwakhiwa kwebhulorho, ukuxhaswa kwezakhiwo, njl., ngakumbi xa izakhiwo zifuna ukudityaniswa kunye nokugoba.
IBanga C: Ngenxa yamandla ayo aphezulu, isetyenziswa rhoqo kwizicelo eziphantsi kwemithwalo ephezulu, njengokwakhiwa kwamashishini, izakhiwo zokuxhasa oomatshini obunzima, njalo njalo.
Ukuqheleka
Ngelixa iBanga B neBanga C lahluka ngeendlela ezininzi, zikwabelana ngeempawu ezifanayo.
Ukumila kwecandelo elifanayo
Iimilo zecandelo elinomqolo zingqukuva, isikwere, uxande, kunye neoval.
Unyango lobushushu
Zonke zivumela intsimbi ukuba igxininise okanye ikhutshwe.
IiNkqubo zoVavanyo ezifanayo
Zombini iBanga B kunye no-C kufuneka zihlangabezane neemfuno ze-ASTM A500 zohlalutyo lwe-thermal, uhlalutyo lwemveliso, uvavanyo lwe-tensile, uvavanyo lwe-Flattening, uvavanyo lwe-Flaring, kunye noVavanyo lwe-Wedge Crush.
Ukunyamezelwa kweDimensional efanayo
Umzekelo wecandelo elinomngxuma elingqukuva.
Iimveliso zethu ezinxulumeneyo
Ekukhetheni ukuba usebenzisa i-ASTM A500 yeBanga B okanye iBanga C, ezona mfuno zobunjineli kunye nokusebenza kakuhle kweendleko kufuneka kuthathelwe ingqalelo.
Umzekelo, kwizakhiwo ezingadingi ukomelela okuphezulu kodwa ukomelela okuhle, iBakala B linokuba lolona khetho lungenamali.Kwiiprojekthi ezifuna amandla amaninzi kunye nomthamo wokuthwala umthwalo, iBanga C libonelela ngomsebenzi oyimfuneko, nangona ixabiso eliphezulu.
Iithegi: astm a500, grade b, grade c, grade b vs c.
