GB/T5310-2008Chubhu yesimbi isina musono imhando yechubhu yesimbi yemhando yepamusoro. Chubhu yeboiler yakakamurwa kuita chubhu yeboiler yakajairika uye chubhu yeboiler ine pressure yakakwira zvichienderana nekushanda kwayo pakupisa kwakanyanya. Pipe yeboiler ine pressure yakakwira inonyanya kushandiswa kugadzira maboiler esteam ane pressure yakakwira uye pamusoro pe pressure, mapaipi nemamwe mabhoiler esteam ane carbon structural steel emhando yepamusoro, alloy structural steel uye chubhu yesimbi isina steel ine pressure yakakwira. [1] Machubhu aya eboiler anoshanda pakupisa kwakanyanya uye kumanikidzwa, achigadzira gasi reflue rinopisa zvakanyanya uye utsi hwemvura, izvo zvinogona kukonzera oxidation uye ngura.

Giredhi resimbi

(1) Simbi yemhando yepamusoro yesimbi yekabhoni 20G, 20MnG, 25MnG. 

(2) Simbi yesimbi ine alloy structure 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, nezvimwewo. 

(3) Simbi inodzivirira kupisa nengura inoshandiswa zvakanyanya 1Cr18Ni9, 1Cr18Ni11Nb boiler tube pamwe nekuona kuti makemikari akagadzirwa uye hunhu hwemakanika, kuyedza kumanikidzwa kwemvura, kuyedza kupenya, uye kudzvanywa. Machubhu esimbi anounzwa ari mumamiriro ekurapa kupisa. 

Pamusoro pezvo, chimiro che microstructure, saizi yezviyo uye rukoko rwekubvisa kabhoni mumachubhu esimbi apera zvinodiwawo.

Pamusoro pechibhaira chesimbi chisina musono chine pressure yakakwiraGB/T5310-2008zvataurwa pamusoro apa, zvigadzirwa zvikuru zvekambani yedu ndeizvi:

ASTMA210(A10M)-2012Boiler yesimbi yekabhoni yepakati uye pombi yesimbi isina musono yesuperheater, chinhu chikuru iSA210 GrA1,SA210GrC;
