Musiyano Mukuru pakati peA192 neA179: A192 inoisakushivirira kwakasimba kweukobvu hwemadzirouye yakakodzeramashandisirwo ebhoira rekumanikidza repamusoroKana kumanikidzwa kwedhizaini kuchipfuura muganho weA179, A192 ndiyo inosarudzwa. Dzese dzine makemikari akafanana uye simba rakaenzana, asi A192 ine zvinodiwa zvakanyanya pakugadzira nekuongorora.

3. ASTM A210 / ASME SA210–Boiler yeSimbi yeKabhoni yepakati nepakati uye machubhu eSuperheater

ASTM A210mavharobhaira resimbi yepakati-kabhoni isina musono uye machubhu ekupisa zvakanyanyauye inopa magiredhi maviri esimba:Giredhi A1uyeGiredhi C.

Nyaya Yekutanga: Simbi yekabhoni iri pakati nepakati

Giredhi A1: Huremu hwekabhoni hunenge 0.27%

Giredhi C: Huremu hwekabhoni hunenge 0.35%

Zvimiro Zvikuru zveMichina:

Giredhi	Simba reKusimba	Simba reGoho	Kuoma
Giredhi A210 A1	≥415 MPa	≥255 MPa	≤143 HBW

Kubatsira kukuru kweA210: Hunhu hwekabhoni huri pakati nepakati hunopasimba rakakwirira uye kuramba tembirichaGiredhi C inopa simba rinosvika 50% kupfuura A179/A192, zvichiita kuti ive yakakodzera tembiricha nedzvinyiriro zvakakwirira. Zvisinei,kupinza nekugadzira simbi ine kabhoni yepakati zvinoda kutarisirwa kwakanyatsonakaA210 yakakodzera masisitimu eboiler nesuperheater ane tembiricha yakagadzirwa ye400°C–450°C.

4. ASTM A213 / ASME SA213–Simbi yeAlloy neSimbi Isina Stainless

ASTM A213mavharomachubhu esimbi esimbi asina musono eferritic neaustenitic alloyyebhaira, superheater, uye heat exchangerzvikamu zvinopisa zvakanyanya.
