ASTM A179 (ASME SA179) ichubhu yesimbi yakaderera-kabhoni inodhonzwa isina musono yekushandisa mu tubular heat exchangers, condensers, uye zvakafanana kupisa kupisa zvikumbiro.
ASTM A179 uye ASME SA179 zviyero zviviri zvakaenzana.Nekuda kwekureruka, ASTM A179 inoshandiswa pazasi.
ASTM A179 inokodzera pombi dzesimbi dzine dhayamita rekunze re1/8″ – 3″ [3.2mm - 76.2mm].
Botop Steelisimbi isina musono pombi stockist kubva kuChina, ichikupa sarudzo hombe yemhando yepamusoro ASTM A179/ASME SA179 inotonhorera inodhonzwa isina musono pombi dzesimbi.
Isu takazvipira kupa vatengi vedu zvigadzirwa zvemhando yepamusoro uye masevhisi kuti tive nechokwadi chekuti mapurojekiti ako anofamba zvakanaka.Sarudza Botop Steel, uye sarudza shamwari yakavimbika.
Isu takatotaura kuti iyo A179 inogadzirwa uchishandisa inotonhorera-inodhonzwa musono kugadzira maitiro.Ndeapi maitiro chaiwo anobatanidzwa mukugadzira-inodhonzwa isina musono?Ndokumbira utarise iyo inotevera nzira yekuyerera chati.
Mune ASTM standard,A556zvakare inoshandisa iyo inotonhora-inodhonzwa isina musono nzira yekugadzira asi yakanangana netubular mvura inodziya.Vaya vanofarira vanogona kuziva zvakawanda.
Mushure mekudhirowa kunotonhora kwekupedzisira, machubhu esimbi anodziyirwa patembiricha ye1200°F [650°C] kana kupfuura.

ASTM A179 haibvumire kuwedzerwa kwezvimwe zvinhu kune kemikari.
Kuoma kwechubhu yesimbi hakufanire kudarika 72 HRBW (Rockwell kuoma).

Imwe neimwe pombi ichaiswa pasi pe hydraulic pressure test kana, kana mutengi ataura kudaro, bvunzo yemagetsi isingaparadzi inogona kushandiswa pachinzvimbo.
Iyo chubhu yesimbi inochengetedza kudzvanywa kweinenge 5s isina kubuda.
Iyo test pressure inoverengerwa uchishandisa inotevera formula:
Inch - Pound Units: P = 32000 t/D
SI Units: P = 220.6t/D
P = hydrostatic test pressure, psi kana MPa;
t = kutsanangurwa kwemadziro ukobvu, mukati kana mm;
D = yakataurwa kunze kwedhayamita, mukati kana mm.
Inotevera ndeye yakajairwa A179 kurongedza, uye yakagadziridzwa kurongedza inogona zvakare kupihwa zvinoenderana nezvinodiwa zveprojekiti.
Pombi isina chinhu, yakasviba coating (yakagadzirirwa);
6" uye pasi saizi Mumasumbu ane machira maviri edonje, mamwe saizi mune yakasununguka;
Zvose zvinopera nevadziviriri vekupedzisira;
