I-America Standard ASTM A588 Corten Steel Plate Piling kanye neStructural Steel Truss Bridge

I-ASTM A588 imboza umumo wensimbi yesakhiwo esinengxubevange ephezulu yamandla aphansi, amapuleti, kanye nezinsimbi zokwakha ezishiselwe, ezicijile, noma ezibhawudi kodwa ezihloselwe ukusetshenziswa kumabhuloho ashiselwe kanye nezakhiwo lapho ukonga ngesisindo noma ukuqina okungeziwe kubalulekile.

I-ASTM A588 iwukuqina okuphezulu kwesisekelo sensimbi yesakhiwo esinengxubevange ephansi enamandla aphezulu kanye nokumelana nokugqwala okuthuthukisiwe komkhathi kumajamo ensimbi yesakhiwo njengama-engeli, isiteshi nemishayo, kanye nepuleti lensimbi nemigoqo.I-ASTM A588 isetshenziselwa ikakhulukazi:
Amabhuloho Abahamba ngezinyawo
I-Highway Bridge Girders nezinye izingxenye zebhuloho
Ukwakhiwa kwemikhumbi
Amathangi
Izinqola zikaloliwe kanye neziqukathi
Uthango
Izithombe eziqoshiwe

Ukucaciswa kwe-A588 kuhloswe kakhulu ukuthi kusetshenziswe ezinhlelweni ezingapendiwe, lapho ukonga ngesisindo noma ukuqina okwengeziwe kubalulekile kanye nomjikelezo wempilo omude ngenxa yezakhiwo zawo ezimelana nokugqwala kanye/noma ukuzuza ukubukeka okujabulisayo.

Ukumelana nokugqwala komkhathi kwe-A588 kungcono kakhulu kunezinsimbi zekhabhoni ezifana ne-A36 ne-A572-50 enokwengezwa kwethusi noma ngaphandle kwayo.Uma iklanywe kahle futhi ivezwe emkhathini, i-A588 ilungele izinhlelo zokusebenza eziningi ezisesimweni esingapendiwe.

I-ASTM A588 inamandla okukhiqiza angama-50ksi amancane kanye namandla okudonsa angama-70ksi amancane.

Ukuhlukaniswa:
1. High weathering steel
Insimbi yesakhiwo sokumelana nesimo sezulu esiphezulu iwukwengeza inani elincane lekhopha, i-phosphorus, i-chromium, nezinto ze-nickel ensimbi ukuze kwakhe ungqimba oluvikelayo ebusweni beqoqo lensimbi ukuze kuthuthukiswe ukusebenza kwensimbi ngokumelene nokugqwala komkhathi.Ungakwazi futhi ukwengeza inani elincane le-molybdenum, i-niobium, izakhi ezifana ne-vanadium, i-titanium ne-zirconium zingacwenga okusanhlamvu, zithuthukise izakhiwo zensimbi, zithuthukise amandla kanye nokuqina kwensimbi, zehlise izinga lokushisa lokuguquka eliphukayo, futhi zenze kube ukumelana kangcono ne-brittle fracture.
2. Weathering steel for isakhiwo Welding
Izakhi ezengezwe ebangeni lensimbi, ngaphandle kwe-phosphorus, ngokuyisisekelo zifana nezinsimbi zesakhiwo ezimelene nesimo sezulu, futhi imisebenzi yazo iyafana futhi ithuthukisa ukusebenza kokushisela.

Izici:

Insimbi ye-Weathering inezici zokuqina, ukwelula kwepulasitiki, ukwakha, ukushisela nokusika, ukumelana nokugqoka, ukumelana nokushisa okuphezulu nokumelana nokukhathala kwensimbi ephezulu;ukumelana nesimo sezulu izikhathi ezingu-2-8 kune-carbon steel evamile, futhi ukusebenza kwe-coating kungu-1.5 we-carbon steel evamile.Izikhathi ezingu-10, ukusebenza kwe-coating izikhathi ezingu-1.5-10 kune-carbon steel evamile, ingasetshenziselwa ukugqoka okuncanyana, ukumboza okungenalutho noma ukugqoka okulula.Le nsimbi inezici zokungagqwali, ukumelana nokugqwala, ukuphila okunwetshiwe, ukunciphisa nokunciphisa ukusetshenziswa, ukonga abasebenzi nokonga amandla, okuzuzisa abakhiqizi bezingxenye nabasebenzisi.Insimbi yesimo sezulu inokumelana nokugqwala okungcono emkhathini.Izinsimbi zesimo sezulu zingancishiswa, zivezwe noma zidwetshwe kalula.Isistimu yensimbi ekwazi ukumelana nokugqwala, ukunwetshwa kwempilo, ukonga abasebenzi, ukunciphisa ukusetshenziswa nokuthuthukiswa kwayo kuyindlela entsha, ubuchwepheshe obusha kanye nenqubo entsha engahlanganiswa nensimbi yesimanje, ukuze iqhubeke nokuthuthuka nokusungula izinto ezintsha.Isistimu yensimbi.

Izinzuzo:

Insimbi yesimo sezulu yenziwe nge-carbon steel evamile enenani elincane lezinto ezimelana nokugqwala njengethusi ne-nickel.Inezici zamandla ensimbi, i-ductility, ukwakha, i-welding, i-abrasion, izinga lokushisa eliphezulu, ukukhathala, njll;ukumelana nesimo sezulu yi-2 ~ 8 yensimbi ye-carbon evamile Ukusebenza kwe-coating izikhathi ezingu-1.5 ~ 10 kune-carbon steel evamile, engasetshenziswa ekuhlanganiseni okuncanyana, okungenalutho noma okwenziwe lula.Insimbi inezici zokumelana nokugqwala, ukumelana nokugqwala nokuphila isikhathi eside kwezingxenye, ukunciphisa nokunciphisa ukusetshenziswa, kanye nezici zokonga umsebenzi nezonga amandla, ezizuzisa abakhiqizi bezingxenye nabasebenzisi.

Isicelo:

Ukusetshenziswa kwensimbi yesakhiwo sokumelana nesimo sezulu esiphezulu kungcono kunensimbi yokumelana nesimo sezulu yesakhiwo esishiselwe ngenxa yokumelana nokugqwala komkhathi.Isetshenziselwa ikakhulukazi ukubopha, i-riveting kanye nokushisela izingxenye zesakhiwo zezimoto, iziqukathi, izakhiwo, imibhoshongo nezinye izakhiwo.Uma isetshenziswa njengezingxenye zesakhiwo ezishiselwe, ubukhulu bensimbi akufanele bube bukhulu kuno-16mm.Ukusebenza kwe-welding yensimbi yesimo sezulu yesakhiwo esihlanganisiwe kungcono kunensimbi ephezulu yesimo sezulu, futhi isetshenziselwa ikakhulukazi izingxenye zesakhiwo ezishiselwe amabhuloho, izakhiwo nezinye izakhiwo.
