GB/T5310-2008seamless simbi chubhu rudzi rwemhando yepamusoro simbi chubhu. Iyo boiler chubhu yakakamurwa kuita yakajairwa boiler chubhu uye yakanyanya kudzvanywa boiler chubhu zvinoenderana nekuita kwayo kupisa kwakanyanya. High pressure boiler pombi inonyanya kushandiswa kugadzira kudzvanywa kwepamusoro uye pamusoro pekumanikidza chiutsi boilers, pombi uye imwe yakakwirira-yemhando kabhoni yakarongeka simbi, alloy dhizaini simbi uye isimbi inodzivirira kupisa simbi isina musono simbi pombi. [1] Aya machubhu ebhailer anoshanda pakupisa kwakanyanya uye kudzvanywa, achigadzira yakanyanya-tembiricha flue gasi uye mhute yemvura, iyo inotarirwa kune oxidation uye ngura.

The simbi giredhi

(1) High quality carbon structural simbi simbi 20G, 20MnG, 25MnG. 

(2) Alloy chimiro simbi 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, nezvimwewo. 

(3) Ngura inodzivirira kupisa simbi inowanzoshandiswa 1Cr18Ni9, 1Cr18Ni11Nb boiler chubhu mukuwedzera kuve nechokwadi chemakemikari kuumbwa uye michina zvivakwa, kuita mvura yekumanikidza bvunzo, kuita flaring, compression bvunzo. Simbi machubhu anounzwa mukupisa kurapwa mamiriro. 

Uye zvakare, iyo microstructure, saizi yezviyo uye decarburization layer yeakapedzwa simbi machubhu inodiwa zvakare.

Pamusoro peiyo yakanyanya kudzvanywa boiler isina seamless simbi chubhuGB/T5310-2008zvataurwa pamusoro apa, zvigadzirwa zvekambani yedu ndezvi:

ASTMA210(A10M)-2012Yepakati kabhoni simbi bhaira uye superheater musono simbi pombi, chikuru zvinhu SA210 GrA1,SA210GrC;
