Chii chinonzi ASTM A179/ASME SA179?

ASTM A179 (ASME SA179) ichubhu yesimbi isina musono inodhonzwa nekabhoni shoma inotonhorera inoshandiswa muzvishandiso zvekupisa zvine machubhu, macondenser, uye zvimwe zvakafanana zvinoshandiswa pakufambisa kupisa.

ASTM A179 neASME SA179 zviyero zviviri zvakaenzana zvachose. Kuti zvive nyore, ASTM A179 inoshandiswa pazasi.

Range yeDimension

ASTM A179 yakakodzera mapaipi esimbi ane dhayamita yekunze ye1/8″ – 3″ [3.2mm - 76.2mm].

Simbi yeBotopikambani inotengesa mapaipi esimbi asina musono kubva kuChina, ichikupa sarudzo yakakura yemapombi esimbi asina musono emhando yepamusoro eASTM A179/ASME SA179.

Takazvipira kupa vatengi vedu zvigadzirwa nemasevhisi emhando yepamusoro kuti tive nechokwadi chekuti mapurojekiti enyu anofamba zvakanaka. Sarudza Botop Steel, uye sarudza mubatsiri akavimbika.

Maitiro Ekugadzira

Tatotaura kuti A179 inogadzirwa uchishandisa nzira yekugadzira isina musono inodhonzwa inotonhora. Ndeapi maitiro chaiwo anobatanidzwa mukugadzira isina musono inodhonzwa inotonhora? Ndapota ona chati inotevera yenzira yekuyerera kwemaitiro.

Muchiyero cheASTM,A556inoshandisawo nzira yekugadzira isina musono inodhonzwa inotonhora asi inonyanya kushandiswa pakudziisa mvura ine machubhu. Avo vanofarira vanogona kuziva zvakawanda.

Kurapa Kupisa

Mushure mekudhirowa kwekupedzisira kwechando, machubhu esimbi anogadziriswa kupisa patembiricha ye1200°F [650°C] kana kupfuura.

Kuedzwa kweHydrostatic

Pombi yega yega inofanira kuongororwa kumanikidzwa kwemvura kana, kana mutengi akataura kudaro, bvunzo yemagetsi isingaparadze inogona kushandiswa panzvimbo payo.

Chubhu yesimbi inochengetedza kumanikidzwa kwemasekonzi mashanu pasina kubuda mvura.

Kumanikidzwa kwebvunzo kunoverengerwa uchishandisa fomura inotevera:

Zviyero zveInch - Paundi: P = 32000 t/D

Zvikamu zveSI: P = 220.6t/D

P = kumanikidzwa kwekuyedza kwehydrostatic, psi kana MPa;

t = ukobvu hwemadziro hwakatarwa, mu. kana mm;

D = dhayamita yekunze yakatarwa, mukati kana mm.
