Amathegi Omkhiqizo

Iyini i-ASTM A179/ASME SA179?

I-ASTM A179 (I-ASME SA179) iyipayipi lensimbi elingenamthungo elidonswa ngekhabhoni ephansi elisetshenziswa kuma-heat exchanger, ama-condenser, kanye nezinhlelo zokusebenza ezifanayo zokudlulisa ukushisa.

I-ASTM A179 kanye ne-ASME SA179 yizindinganiso ezimbili ezilingana ngokuphelele. Ukuze kube lula, i-ASTM A179 isetshenziswa ngezansi.

Ububanzi Bobukhulu

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

Insimbi yeBotopungumthengisi wamapayipi ensimbi angenamthungo ovela eShayina, okunikeza ukukhetha okukhulu kwamapayipi ensimbi angenamthungo asezingeni eliphezulu e-ASTM A179/ASME SA179.

Sizinikele ekuhlinzekeni amakhasimende ethu ngemikhiqizo nezinsizakalo ezisezingeni eliphezulu ukuqinisekisa ukuthi amaphrojekthi akho asebenza kahle. Khetha i-Botop Steel, bese ukhetha umlingani othembekile.

Inqubo Yokukhiqiza

Sesivele sishilo ukuthi i-A179 ikhiqizwa kusetshenziswa inqubo yokukhiqiza engenamthungo edonswa ngokubandayo. Yiziphi izinqubo ezithile ezihilelekile ekukhiqizeni okungenamthungo okudonswa ngokubandayo? Sicela ubheke ishadi lokugeleza kwenqubo elilandelayo.

Ngokwezinga le-ASTM,A556isebenzisa futhi inqubo yokukhiqiza engenamthungo edonswa ngokubandayo kodwa yenzelwe ngqo ama-heater amanzi anezimbobo. Labo abanentshisekelo bangathola okwengeziwe.

Ukwelashwa Kokushisa

Ngemva kokudweba kokugcina kokubanda, amapayipi ensimbi aphathwa ngokushisa emazingeni okushisa angu-650°C noma ngaphezulu.

Ukwakheka Kwamakhemikhali kwe-ASTM A179

I-ASTM A179	0.06-0.18%	0.27-0.63%	Ubuningi obungu-0.035%	Ubuningi obungu-0.035%

I-ASTM A179 ayivumeli ukungezwa kwezinye izakhi ekwakhiweni kwamakhemikhali.

Ukuqina kwe-ASTM A179

Ubulukhuni bepayipi lensimbi akumele budlule u-72 HRBW (ubulukhuni beRockwell).

Ukuhlolwa Kwamanzi

Ipayipi ngalinye kufanele lihlolwe umfutho we-hydraulic noma, uma umthengi esho kanjalo, kungasetshenziswa ukuhlolwa kukagesi okungonakalisi esikhundleni salokho.

Ishubhu lensimbi ligcina ingcindezi okungenani amasekhondi angu-5 ngaphandle kokuvuza.

Ingcindezi yokuhlola ibalwa kusetshenziswa ifomula elandelayo:

Amayunithi e-Inch - Pound: P = 32000 t/D

Amayunithi e-SI: P = 220.6t/D

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

t = ubukhulu bodonga obucacisiwe, ngo. noma mm;

D = ububanzi obungaphandle obucacisiwe, ngaphakathi noma mm.
