Inqubo yokukhiqiza yeIsitimela sensimbi esijwayelekile se-AREMAngokuvamile kuhlanganisa izinyathelo ezilandelayo:
Ukulungiswa kwempahla eluhlaza: Lungiselela izinto ezingavuthiwe zensimbi, ngokuvamile insimbi yekhwalithi ephezulu ye-carbon structural noma insimbi ye-alloy ephansi.
Ukuncibilikiswa nokubunjwa: Izinto zokusetshenziswa ziyancibilika, bese insimbi encibilikisiwe iphonswa kumabhilidi ensimbi okuqala ngokujikijelwa okuqhubekayo noma ukuthululwa.
Ukucwenga nokuginqika: Ukucwengisiswa kwe-billet yensimbi yokuqala, okuhlanganisa ukususa ukungcola kanye nokulungisa ukwakheka, bese kugoqwa ibhilethi yensimbi ngokusebenzisa okokusebenza okuginqikayo kube amabhilidi ethrekhi ahlangabezana nezindinganiso zikazwelonke.
Ukwelashwa kusengaphambili: Ukwelashwa kusengaphambili kwamabhilidi ethrekhi, okuhlanganisa ukufoja, ukwelashwa kokushisa nokwelashwa kwendawo, njll., ukuze kuthuthukiswe amandla nokuqina kwamareyili.
Ukugingqika nokubunjwa: I-billet yethrekhi ehlanzwe ngaphambilini iyagoqwa futhi yenziwe ngomshini ogoqayo ukuze yenze iphrofayili kaloliwe ehlangabezana nezidingo ezijwayelekile zikazwelonke.
Ukuhlola nokulawulwa kwekhwalithi: Ukuhlolwa okuqinile nokulawulwa kwekhwalithi kuyenziwa kumareyili akhiqiziwe ukuze kuqinisekiswe ukuthi ayahlangabezana namazinga kazwelonke kanye nezidingo zamakhasimende.
Ukupakisha nokuphuma efekthri: Ojantshi abafanelekayo bayapakishwa futhi bamakwe, bese behanjiswa ekhasimendeni noma bagcinwe endaweni yokugcina izimpahla elinde ukuthunyelwa.
Isitimela sensimbi esijwayelekile se-ASTM babe nezici ezilandelayo:
Amandla aphezulu: Izinga laseMelikaojantshizenziwe ngensimbi yekhwalithi ephezulu, enamandla amakhulu nokuqina futhi engakwazi ukumelana nokucindezela okukhulu nomthelela wokusebenza kwezitimela.
Ukumiswa kokucaciswa: Ukucaciswa nobukhulu bamajantshi ajwayelekile aseMelika akhiwe ngokuqinile ngokuhambisana namazinga, okuqinisekisa ukufana nokushintshana kohlelo lwesitimela.
Ukumelana nokugqokwa okuqinile: Ingaphezulu le-American standard rails liphathwe ngokukhethekile futhi linokumelana okuqinile nokugqokwa, okunganciphisa ukuguga kwethrekhi nokwelula impilo yesevisi.
Ukumelana nokugqwala okuhle: Ingaphezulu lama-rails ajwayelekile aseMelika selashwe i-anti-corrosion, engamelana ne-oxidation nokugqwala futhi igcine isimo sokusebenzisa kahle.
Ububanzi obubanzi bokusebenza: Ojantshi abajwayelekile baseMelika bafanele imizila yezitimela ehlukahlukene, okuhlanganisa nojantshi besitimela abanesivinini esikhulu, ojantshi abajwayelekile kanye nojantshi wezimpahla, njll., futhi banokuguquguquka okuqinile nokusebenziseka.
