Kungani amaflange e-ASTM A516 Gr.70 ebiza kakhulu kunamaflange e-ASTM A105?

Kokubili i-ASTM A516 Gr.70 kanye ne-ASTM A105 yizinsimbi ezisetshenziselwa izinhlelo zokusebenza ezahlukene, umkhumbi wokucindezela kanye nokwakhiwa kwe-flange ngokulandelanayo. Umehluko wentengo phakathi kwakho kokubili ungabangelwa izici eziningana:

1. Umehluko wezindleko ezibonakalayo:

I-ASTM A516 Gr.70 ivamise ukusetshenziselwa ukwakha imikhumbi yokucindezela, futhi izinto zayo kufanele zihlangabezane nezimfuneko eziphakeme, okuhlanganisa amandla aqinile, amandla okukhiqiza, ukuqina komthelela, njll. Ngokuphambene,I-ASTM A105isetshenziselwa ukwenza ama-flange, ngokuvamile anezidingo zempahla ephansi. Ngakho-ke, izindleko zokukhiqiza ze-ASTM A516 Gr.70 zingase zibe phezulu.

2. Umehluko wezakhiwo ezibonakalayo:

Izinto ze-ASTM A516 Gr.70 ngokuvamile zidinga ukucutshungulwa kobunjiniyela nokuphathwa okwengeziwe ukuze kuhlangatshezwane nezidingo zazo zohlelo lokusebenza ngaphansi kwengcindezi ephezulu nezimo zokushisa eziphezulu. Lokhu kungase kudinge inqubo eyengeziwe nokulawulwa kwezinto ezibonakalayo, kukhuphule ngokwengeziwe izindleko.

3. Ukufunwa kwemakethe nokuhlinzeka:

Isidingo semakethe kanye nokuhlinzekwa kwezinto ezahlukene nakho kuzothinta intengo. Uma isidingo se-ASTM A516 Gr.70 siphezulu futhi ukunikezwa kukuncane uma kuqhathaniswa, khona-ke intengo ingase yenyuke. Ngokuphambene nalokho, uma ukunikezwa kwe-ASTM A105 kwanele futhi isidingo sincane, intengo ingase ibe phansi.

4. Ubunkimbinkimbi bokukhiqiza:

Ama-Flangesngokuvamile kulula ukuwenza kunemikhumbi yokucindezela ngoba ngokuvamile iyimimo elula. Okubalulekile kwe-ASTM A516 Gr.70 kungase kudinge umsebenzi wobunjiniyela owengeziwe ukuze kuhlangatshezwane nezidingo zemikhumbi yokucindezela yomumo nosayizi abahlukahlukene.

Kafushane, umehluko wentengo phakathi kwe-ASTM A516 Gr.70 kanye ne-ASTM A105 ungabangelwa izici ezihlukahlukene ezifana nezakhiwo ezibonakalayo, isidingo semakethe, ukutholakala, nobunkimbinkimbi bokukhiqiza. Lapho uthenga, lezi zici kufanele zikalwe ngokusekelwe ezidingweni ezithile kanye nezinhlelo zokusebenza ukuze kukhethwe into efanele futhi kucatshangelwe inani layo.
