Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Iyini i-ASTM A179/ASME SA179?

I-ASTM A179 (I-ASME SA179) iyishubhu yensimbi engenamthungo enekhabhoni ebandayo edonsa umoya ukuze isetshenziswe kwizishintshisi zokushisa ezishubhu, izikhonsali, nezinhlelo zokusebenza ezifanayo zokudlulisa ukushisa.

I-ASTM A179 ne-ASME SA179 amazinga amabili alingana ngokuphelele.Ukuze kube lula, i-ASTM A179 isetshenziswa ngezansi.

Ububanzi be-Dimension

I-ASTM A179 ifanele amapayipi ensimbi anobubanzi obungaphandle obungu-1/8″ - 3″ [3.2mm - 76.2mm].

Insimbi ye-Botopiyisitokofela samapayipi ensimbi angenamthungo esivela e-China, ekunikeza ukukhetha okukhulu kwekhwalithi ephezulu ye-ASTM A179/ASME SA179 yamapayipi ensimbi adonswa ngokubanda angenamthungo.

Sizinikezele ekunikezeni amakhasimende ethu imikhiqizo namasevisi ekhwalithi ephezulu kakhulu ukuze siqinisekise ukuthi amaphrojekthi akho ahamba kahle.Khetha i-Botop Steel, bese ukhetha umlingani othembekile.

Inqubo Yokukhiqiza

Sesikushilo ukuthi i-A179 ikhiqizwa kusetshenziswa inqubo yokukhiqiza engenamthungo edonsa ngamakhaza.Yiziphi izinqubo ezithile ezihilelekile ekukhiqizeni okungenamthungo okudonsa abandayo?Sicela ubheke ishadi lokugeleza kwenqubo elandelayo.

Ngokwezinga le-ASTM,A556futhi isebenzisa inqubo yokukhiqiza engenamthungo edonswa abandayo kodwa iqondene ngqo nezishisi zamanzi ezishubhu.Abanentshisekelo bangathola okwengeziwe.

Ukwelashwa Kokushisa

Ngemva komdwebo wokugcina obandayo, amashubhu ensimbi afakwa ekushiseni okungaba ngu-1200°F [650°C] noma ngaphezulu.

I-ASTM A179 ayikuvumeli ukungezwa kwezinye izakhi ekwakhekeni kwamakhemikhali.

Ukuqina kwe-ASTM A179

Ukuqina kweshubhu lensimbi akumele kudlule ku-72 HRBW (ukuqina kwe-Rockwell).

Ukuhlolwa kwe-Hydrostatic

Ipayipi ngalinye kufanele lihlolwe ingcindezi ye-hydraulic noma, uma umthengi esho kanjalo, kungase kusetshenziswe ukuhlolwa kukagesi okungangonakali.

Ishubhu lensimbi ligcina ingcindezi okungenani ama-5s ngaphandle kokuvuza.

Ingcindezi yokuhlola ibalwa kusetshenziswa ifomula elandelayo:

Intshi - Amayunithi Ephawundi: P = 32000 t/D

Amayunithi we-SI: P = 220.6t/D

P = ingcindezi yokuhlola i-hydrostatic, i-psi noma i-MPa;

t = ukujiya kodonga olucacisiwe, ngaphakathi noma mm;

D = kucaciswe ububanzi obungaphandle, in. noma mm.
