Izindaba - I-ASTM A283 vs ASTM A709: Umehluko Obalulekile Ekubunjweni Kwamakhemikhali, Izakhiwo Zemishini, kanye Nezicelo

Njengoba ukutshalwa kwezimali kwengqalasizinda yomhlaba wonke kuqhubeka nokukhula, osonkontileka, abakhiqizi bensimbi, kanye namaqembu okuthenga banaka kakhulu umehluko wokusebenza phakathi kwezindinganiso ezahlukene zensimbi ezakhiweni.I-ASTM A283futhiI-ASTM A709yizindinganiso ezimbili ezivame ukusetshenziswa zepuleti lensimbi, ngayinye inezici ezihlukile ngokwesakhiwo samakhemikhali, izakhiwo zemishini, kanye nokusetshenziswa. Lesi sihloko sinikeza ukuqhathanisa okujulile kochwepheshe ekwakheni amabhuloho, izakhiwo zokwakha, kanye namaphrojekthi ezimboni.

I-ASTM A283: Insimbi Yesakhiwo Sekhabhoni Engabizi Kakhulu

I-ASTM A283iyindinganiso yepuleti lensimbi yesakhiwo sekhabhoni esetshenziswa kabanzi kumaphrojekthi okwakha nobunjiniyela ajwayelekile. Izinzuzo zayo zifaka:

Kuyonga futhi kuyabiza kakhulu

Ukushibilika okuhle nokusebenza kahle

Ifanele ukusetshenziswa kwesakhiwo okunamandla aphansi

Amamaki avamile afaka phakathi i-A283 Grade A, B, C, kanye no-D, kanyeIbanga Cyizona ezisetshenziswa kakhulu. Izinhlelo zokusebenza ezivamile zifaka amathangi okugcina izinto, izingxenye zesakhiwo ezilula, amapuleti okwakha ajwayelekile, kanye nezingxenye zobunjiniyela ezingabalulekile.

Ngokuphathelene nokwakheka kwamakhemikhali, i-A283 iyinsimbi engenakhabhoni ephansi enezinto ezilula futhi ayinayo i-alloy eyengeziwe, okwenza ibe ngengabizi kakhulu kodwa ingaqini futhi iqine kangako.

I-ASTM A709: Insimbi Enamandla Kakhulu Yebhuloho

Ngokuphambene nalokho, i-ASTM A709 iyi-indinganiso yensimbi yesakhiwo eyenzelwe ngqo ukwakhiwa kwebhuloho, esetshenziswa kabanzi kumabhuloho omgwaqo omkhulu kanye nawesitimela, okuhlanganisa imishayo emikhulu, imishayo yokuwela, amapuleti edekhi, kanye nezakhiwo ze-truss.

Amamaki avamile afaka:

Ibanga lesi-36 le-A709

Ibanga lama-50 le-A709

Ibanga le-A709 50W (insimbi yokushisa)

I-HPS 50W / I-HPS 70W (insimbi esebenza kahle kakhulu)

Izinzuzo ezibalulekile ze-A709 zifaka:

Amandla aphezulu okukhiqiza (≥345 MPa yebanga lama-50)

Ukuqina okuhle kakhulu kokushisa okuphansi kokukhathala nokumelana nomthelela

Ukumelana nesimo sezulu okukhethwa kukho ukunciphisa izindleko zokulungisa zesikhathi eside

Le nsimbi esebenza kahle kakhulu yenza i-A709 ifaneleke kakhulu kumabhuloho amade, izakhiwo ezisindayo, kanye namaphrojekthi adinga ukuqina ngokumelene nokugqwala komoya.

Ukuqhathaniswa Kwezakhiwo Zemishini

Impahla	I-ASTM A283 Ibanga C	Ibanga lama-50 le-ASTM A709
Amandla Okukhiqiza	≥ 205 MPa	≥ 345 MPa
Amandla Okudonsa	380–515 MPa	450–620 MPa
Ukuqina Komthelela	Okumaphakathi	Kuhle kakhulu (kufanele amabhuloho)
Ukumelana Nesimo Sezulu	Okujwayelekile	Amazinga okushisa angama-50W/HPS

I-A709 ngokusobala inikeza amandla aphezulu, ukuqina, kanye nokuqina, okwenza ifaneleke kakhulu ekusetshenzisweni kwesakhiwo okunomthwalo omkhulu kanye nokubalulekile.

Izindleko Zokucatshangelwa

Ngenxa yezinto ezengeziwe zokuhlanganisa kanye nezidingo zokusebenza okuphezulu,I-A709 ngokuvamile ibiza kakhulu kune-A283. Kumaphrojekthi aqaphela isabelomali anesidingo esincane sesakhiwo, i-A283 inikeza ukonga okungcono kakhulu kwezindleko. Kodwa-ke, ekwakhiweni kwamabhuloho nezakhiwo ezinemithwalo eminingi, i-A709 iyinto ekhethwayo noma edingekayo.

Ochwepheshe bobunjiniyela bagcizelela ukukhetha uhlobo lwensimbi olufanele ngokusekelwe ezidingweni zesakhiwo kunezindleko zodwa.

Amaphrojekthi athwala umthwalo ophansi, angabalulekile: I-A283 yanele.

Amabhuloho, izakhiwo ezinde, imithwalo yokukhathala ephezulu, noma ukuchayeka ezindaweni ezinzima: I-A709 iyadingeka.

Njengoba ukuthuthukiswa kwengqalasizinda yomhlaba wonke kushesha, isidingo se-ASTM A709 siyaqhubeka nokukhula, kuyilapho i-A283 ihlala izinzile ezimakethe zokwakha nezokwakha amathangi.
