Xa kufikwa kwizicelo zesakhiwo kunye nolwakhiwo, ukukhethwa kwezinto kubalulekile ukuqinisekisa ukhuseleko, ukuqina, kunye nokusebenza. Enye yezinto ezihlonitshwa kakhulu kushishino yile Intsimbi ye-ASTM A252 yeBanga lesi-3. Le nkcazelo ibaluleke kakhulu ekwenzeni iipayipu ezisetyenziswa kwiziseko ezinzulu, nto leyo eyenza ukuba zibe yinxalenye ebalulekileyo kwiiprojekthi ezahlukeneyo zokwakha.
I-ASTM A252 yinkcazo esemgangathweni eyenziwe yi-American Society for Testing and Materials (ASTM) echaza iimfuno ze-welding kunye ne-mthungoumbhobho wentsimbiiipile. Ibanga lesi-3 lelona nqanaba liphezulu lamandla kule nkcazo, kwaye amandla okuvelisa aphantsi angama-50,000 psi (345 MPa). Oku kuyenza ilungele ukusetyenziswa okudinga amandla aphezulu okuthwala umthwalo kunye nokumelana nokuguquguquka.
Enye yezona nzuzo ziphambili ze-ASTM A252 Grade 3 kukudityaniswa kwayo kakuhle, okuvumela ukwenziwa nokufakelwa okusebenzayo. Ulwakhiwo lweekhemikhali lwale ntsimbi luquka izinto ezifana nekhabhoni, i-manganese, kunye ne-silicon, ezinegalelo ekomeleleni nasekuqineni kwayo. Ukongeza, le nto inokumelana neemeko ezinzima zokusingqongileyo, nto leyo eyenza ukuba ifaneleke ukusetyenziswa kwiindawo zaselwandle nakwezinye iindawo ezinzima.
Enyanisweni, i-ASTM A252 Grade 3 isetyenziswa rhoqo ekwakhiweni kweebhulorho, izakhiwo, kunye nezinye iiprojekthi zeziseko ezingundoqo ezifuna iziseko ezinzulu. Amandla ayo okuxhasa imithwalo enzima ngelixa igcina ulungelelwaniso lwesakhiwo lubalulekile kwixesha elide kunye nokhuseleko lwezi zakhiwo.
Isishwankathelo,I-ASTM A252 Ibanga lesi-3Intsimbi sisixhobo esibalulekileyo kushishino lokwakha, inika amandla kunye nokuqina okufunekayo kwizicelo zesiseko esinzulu. Ukuqonda iimpawu kunye neenzuzo zayo kunokunceda iinjineli kunye nabakhi ukuba benze izigqibo ezinolwazi xa bekhetha izixhobo zeeprojekthi zabo, ekugqibeleni oku kukhokelela kwizakhiwo ezikhuselekileyo nezithembekileyo.
