Yintoni i-ASTM A179/ASME SA179?

I-ASTM A179 (ASME SA179) yityhubhu yentsimbi ephantsi enekhabhoni ebandayo etsalwa yintsimbi engenamthungo esetyenziselwa ukutshintshiselana ngobushushu betubula, iicondensers, kunye nokusetyenziswa kobushushu obufanayo.

I-ASTM A179 kunye ne-ASME SA179 yimigangatho emibini elingana ngokupheleleyo.Ukwenzela lula, i-ASTM A179 isetyenziswa ngezantsi.

Uluhlu lweDimension

I-ASTM A179 ifanelekile kwimibhobho yentsimbi enobubanzi obungaphandle be-1/8" - 3" [3.2mm - 76.2mm].

Intsimbi yeBotopsisitokhwe sentsimbi esingenamthungo esivela eTshayina, sikunika ukhetho olukhulu olukumgangatho ophezulu we-ASTM A179/ASME SA179 yemibhobho yentsimbi ebandayo etsalwa ngokubanda.

Sizinikezele ekuboneleleni abathengi bethu ngezona mveliso zikumgangatho ophezulu kunye neenkonzo zokuqinisekisa ukuba iiprojekthi zakho zihamba kakuhle.Khetha iBotop Steel, kwaye ukhethe iqabane elithembekileyo.

Inkqubo yokuVelisa

Sele sichazile ukuba i-A179 iveliswa kusetyenziswa inkqubo yokuvelisa engenamthungo etsalwa ngokubanda.Zeziphi iinkqubo ezithile ezibandakanyekayo kwimveliso engenamthungo etsalwa ngokubanda?Nceda ujonge le tshati yenkqubo elandelayo.

Inkqubo yokwenza umbhobho wentsimbi ongenamthungo otsalwa ngokubanda

Kumgangatho weASTM,A556ikwasebenzisa inkqubo yokuvelisa engenamthungo etsalwa ngokubanda kodwa ilungiselelwe ngokukodwa izifudumezi zamanzi ezishubhu.Abo banomdla banokufumanisa okungakumbi.

Unyango lobushushu

Emva komzobo wokugqibela obandayo, iityhubhu zentsimbi zifakwa kubushushu obungama-650 ngokukaCelsius nangaphezulu.

I-ASTM A179 ayikuvumeli ukongezwa kwezinye izinto kwi-chemical composition.

Ubunzima be-ASTM A179

Ukuqina kwetyhubhu yentsimbi akufunekanga kudlule i-72 HRBW (ukuqina kwe-Rockwell).

Uvavanyo lweHydrostatic

Umbhobho ngamnye uya kufakwa kuvavanyo loxinzelelo lwehydraulic okanye, ukuba umthengi umisela njalo, uvavanyo lombane olungatshabalalisayo lunokusetyenziswa endaweni yoko.

Umbhobho wensimbi ugcina uxinzelelo ubuncinane ubuncinane be-5 ngaphandle kokuvuza.

Uxinzelelo lovavanyo lubalwa kusetyenziswa le fomula ilandelayo:

I-intshi - iiYunithi zePonti: P = 32000 t/D

Iiyunithi ze-SI: P = 220.6t/D

P = uxinzelelo lovavanyo lwe-hydrostatic, i-psi okanye i-MPa;

t = ubukhulu bodonga obuchaziweyo, ngaphakathi okanye mm;

D = icaciswe ngaphandle kwedayamitha, ngaphakathi okanye mm.
