I-GB/T5310-2008ithubhu yensimbi engenamthungo iwuhlobo lweshubhu yensimbi yekhwalithi ephezulu. Ishubhu le-boiler lihlukaniswe libe yishubhu le-boiler elijwayelekile kanye neshubhu le-boiler elicindezelayo ngokuya ngokusebenza kwalo kokushisa okuphezulu. Ipayipi elinomfutho ophakeme we-boiler lisetshenziselwa ikakhulukazi ukukhiqiza umfutho ophezulu kanye nama-boilers omusi wengcindezi angaphezulu kwengcindezi, amapayipi nezinye insimbi yekhwalithi ephezulu ye-carbon structural, i-alloy structural steel kanye nensimbi engagqwali ukumelana nokushisa ipayipi lensimbi engenamthungo. [1] Lawa mashubhu obhayela asebenza kumazinga okushisa aphezulu kanye nokucindezela, akhiqiza igesi yokushisa ephezulu yokushisa kanye nomhwamuko wamanzi, othambekele ekubeni ne-oxidation kanye nokugqwala.

Ibanga lensimbi

(1) Ikhwalithi ephezulu ye-carbon structural steel steel 20G, 20MnG, 25MnG. 

(2) Insimbi yesakhiwo se-alloy 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njll. 

3 Amashubhu ensimbi alethwa esimweni sokwelashwa kokushisa. 

Ngaphezu kwalokho, i-microstructure, usayizi wokusanhlamvu kanye nongqimba lwe-decarburization lwamashubhu ensimbi aphelile nawo ayadingeka.

Ngaphezu kwe-high pressure boiler tube engenamthungo yensimbiI-GB/T5310-2008okukhulunywe ngenhla, imikhiqizo eyinhloko yenkampani yethu yile:

I-ASTMA210(A10M)-2012Ibhoyili yensimbi ye-carbon emaphakathi kanye nepayipi lensimbi elingenamthungo elikhulu, into esemqoka yi-SA210 GrA1,SA210GrC;

ASME SA106/SA-106M-2015, izinto ezisetshenziswayo eziyinhloko yi-GR.B gr.C;

ASME SA-213/SA-213M, izinto ezivamile ze-alloy: T11, T12, T22 kanye ne-T23, T91, P92, T5, T5b, T9, T21, T22, T17;

I-ASTM A335 / A335M – 2018, izinto eziyinhloko yilezi: P11, P12, P22, P5, P9, P23,P91, P92, P2, njll.
