Iithegi zeMveliso

Yintoni i-ASTM A179/ASME SA179?

I-ASTM A179 (I-ASME SA179) yityhubhu yentsimbi engenamthungo etsalwa ngekhabhoni ebandayo esetyenziswa kwi-tubular heat exchangers, i-condenser, kunye nezinye izicelo ezifanayo zokudlulisa ubushushu.

I-ASTM A179 kunye ne-ASME SA179 zimigangatho emibini elingana ngokupheleleyo. Ukuze kube lula, i-ASTM A179 isetyenziswa ngezantsi.

Uluhlu lweMilinganiselo

I-ASTM A179 ifanelekile kwiipayipi zentsimbi ezinobubanzi obungaphandle obuyi-1/8″ – 3″ [3.2mm - 76.2mm].

Intsimbi yeBotopngumthengisi weepayipi zentsimbi ezingenamthungo ovela eTshayina, ekunika ukhetho olukhulu lweepayipi zentsimbi ezingenamthungo ezikumgangatho ophezulu ze-ASTM A179/ASME SA179.

Sizinikele ekuboneleleni abathengi bethu ngeemveliso kunye neenkonzo ezikumgangatho ophezulu ukuqinisekisa ukuba iiprojekthi zakho zihamba kakuhle. Khetha iBotop Steel, kwaye ukhethe iqabane elithembekileyo.

Inkqubo yoMveliso

Sele sikhankanyile ukuba i-A179 iveliswa kusetyenziswa inkqubo yokwenziwa kwemveliso engenamthungo etsalwa ngokubandayo. Ziziphi iinkqubo ezithile ezibandakanyekayo kwimveliso engenamthungo etsalwa ngokubandayo? Nceda ujonge itshathi yenkqubo elandelayo.

Inkqubo yokwenziwa kwemibhobho yentsimbi engenamthungo etsalwa ngokubandayo

Kwimigangatho ye-ASTM,A556ikwasebenzisa inkqubo yokuvelisa engenamthungo etsalwa ngokubandayo kodwa yenzelwe ngokukodwa izifudumezi zamanzi ezineetyhubhu. Abo banomdla banokufumana okungakumbi.

Unyango lobushushu

Emva komzobo wokugqibela wokubanda, iityhubhu zentsimbi zinyangwa ngobushushu kumaqondo obushushu angama-650°C okanye ngaphezulu.

Uvavanyo lwe-Hydrostatic

Umbhobho ngamnye kufuneka uvavanywe ngoxinzelelo lwe-hydraulic okanye, ukuba umthengi uyalela njalo, kungasetyenziswa uvavanyo lombane olungonakalisiyo endaweni yoko.

Ityhubhu yentsimbi igcina uxinzelelo ubuncinane imizuzwana emi-5 ngaphandle kokuvuza.

Uxinzelelo lovavanyo lubalwa kusetyenziswa le fomyula ilandelayo:

Iiyunithi ze-intshi - iPonti: 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 = ububanzi obungaphandle obuchaziweyo, ngaphakathi okanye mm.
