Boiler chubhu yakavhurika kumativi ese uye ine chikamu chisina chinhu, kureba uye nharaunda yesimbi hombe, zvichienderana nenzira dzekugadzira inogona kukamurwa kuita musono wesimbi pombi uye welded simbi pombi, simbi pombi specification ine zviyero zvese (zvakadai sedhayamita kana kureba) uye ukobvu hwemadziro, akati saizi yayo yakakura kwazvo, kubva padhayamita diki kusvika pamamita akati wandei mudhayamita, pombi hombe dhayamita.

Machubhu esimbi anogona kushandiswa pakugadzira mapaipi, midziyo yekupisa, indasitiri yemichina, kutsvaga petroleum geological, magaba, indasitiri yemakemikari uye mabasa akakosha.

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

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

Boiler tube yakakamurwa muzvikamu zviviri:GB/T3087-2018chubhu yebhoyira ine kumanikidzwa kwepakati nepasi,GB/T5310-2018chubhu yebhoyira ine simba repamusoro. Zvigadzirwa zvedu zvikuru zvinosanganisira:

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