Xa kuziwa kwizicelo zokwakha kunye nezakhiwo, ukukhethwa kwezinto eziphathekayo kubalulekile ukuqinisekisa ukhuseleko, ukuqina, kunye nokusebenza. Enye imathiriyeli ehlonitshwa kakhulu kushishino I-ASTM A252 yeBakala 3 yentsimbi. Le ngcaciso ibaluleke kakhulu ekwenzeni iimfumba zemibhobho ezisetyenziswe kwiziseko ezinzulu, okwenza zibe yinxalenye ebalulekileyo kwiiprojekthi zokwakha ezahlukeneyo.
I-ASTM A252 luphawu olusemgangathweni oluphuhliswe nguMbutho waseMelika woVavanyo kunye neMathiriyeli (ASTM) echaza iimfuno ezidityanisiweyo kunye nezingenamthungo.umbhobho wentsimbiiimfumba. IBanga lesi-3 lelona bakala lamandla aphezulu kule nkcazo, kunye namandla okufumana ubuncinci be-50,000 psi (345 MPa). Oku kuyenza ilungele izicelo ezifuna umthamo ophezulu wokuthwala umthwalo kunye nokuchasana nokuguqulwa.
Enye yeenzuzo eziphambili ze-ASTM A252 yeBanga lesi-3 kukukwazi ukuwelda okugqwesileyo, okuvumela ukwenziwa ngokufanelekileyo kunye nokufakwa. Ukwakhiwa kweekhemikhali zale ntsimbi kuquka izinto ezifana nekhabhoni, i-manganese, kunye ne-silicon, ezifaka isandla kumandla kunye nokuqina. Ukongeza, izinto eziphathekayo ziyakwazi ukumelana neemeko ezibuhlungu zokusingqongileyo, ziyenze ilungele ukusetyenziswa elwandle kunye nezinye iindawo ezinomngeni.
Ngapha koko, i-ASTM A252 yeBanga lesi-3 ihlala isetyenziswa ekwakhiweni kweebhulorho, izakhiwo, kunye nezinye iiprojekthi zeziseko ezingundoqo ezifuna iziseko ezinzulu. Ikhono layo lokuxhasa imithwalo enzima ngelixa igcina ingqibelelo yesakhiwo ibaluleke kakhulu kwixesha elide kunye nokukhuseleka kwezi zakhiwo.
Isishwankathelo,I-ASTM A252 iBanga lesi-3intsimbi yinto ephambili kushishino lokwakha, inika amandla kunye nokuqina okufunekayo kwizicelo ezisisiseko ezinzulu. Ukuqonda iimpawu zayo kunye neenzuzo kunokunceda iinjineli kunye neekontraka ukuba benze izigqibo ezinolwazi xa bekhetha izixhobo zeeprojekthi zabo, ekugqibeleni kubangele izakhiwo ezikhuselekileyo nezithembekileyo.
