Uma kukhulunywa ngokusetshenziswa kwezakhiwo nezakhiwo, ukukhethwa kwezinto kubalulekile ukuqinisekisa ukuphepha, ukuqina, kanye nokusebenza kahle. Enye yezinto ezihlonishwa kakhulu embonini yile Insimbi ye-ASTM A252 Grade 3. Le ncazelo ibaluleke kakhulu ekwakhiweni kwezinqwaba zamapayipi ezisetshenziswa ezisekelweni ezijulile, okwenza zibe yingxenye ebalulekile kumaphrojekthi ahlukahlukene okwakha.
I-ASTM A252 iyincazelo ejwayelekile ethuthukiswe yi-American Society for Testing and Materials (ASTM) echaza izidingo zokushintshwa nokungathungwaipayipi lensimbiama-piles. Ibanga lesi-3 liyizinga lamandla aphezulu kakhulu kule ncazelo, elinamandla okukhiqiza okungenani angu-50,000 psi (345 MPa). Lokhu kwenza kube kuhle kakhulu ezinhlelweni zokusebenza ezidinga amandla aphezulu okuthwala umthwalo kanye nokumelana nokuguquguquka.
Enye yezinzuzo eziyinhloko ze-ASTM A252 Grade 3 ukushibilika kwayo okuhle kakhulu, okuvumela ukwenziwa nokufakwa okuphumelelayo. Ukwakheka kwamakhemikhali kwale nsimbi kufaka phakathi izinto ezifana ne-carbon, i-manganese, ne-silicon, ezifaka isandla ekuqineni nasekuqineni kwayo. Ngaphezu kwalokho, le nto ingamelana nezimo zemvelo ezinzima, okwenza ifaneleke ukusetshenziswa ezindaweni zasolwandle nakwezinye izindawo eziyinselele.
Eqinisweni, i-ASTM A252 Grade 3 ivame ukusetshenziswa ekwakhiweni kwamabhuloho, izakhiwo, kanye neminye imisebenzi yengqalasizinda edinga izisekelo ezijulile. Amandla ayo okusekela imithwalo esindayo ngenkathi igcina ubuqotho besakhiwo kubalulekile ekuphileni isikhathi eside nasekuphepheni kwalezi zakhiwo.
Ngokufigqiwe,Ibanga lesi-3 le-ASTM A252Insimbi iyinto ebalulekile embonini yokwakha, inikeza amandla nokuqina okudingekayo ekusetshenzisweni kwesisekelo esijulile. Ukuqonda izici nezinzuzo zayo kungasiza onjiniyela kanye nabakhi benkontileka ukuthi benze izinqumo ezinolwazi lapho bekhetha izinto zamaphrojekthi abo, okuholela ekugcineni ezakhiweni eziphephile nezinokwethenjelwa.
