I-boiler tube ivulekile kuzo zombili iziphetho futhi inesigaba esingenalutho, ubude kanye nendawo ezungezile yensimbi enkulu, ngokwezindlela zokukhiqiza zingahlukaniswa zibe ipayipi lensimbi engenamthungo kanye nepayipi lensimbi elishiselwe, ukucaciswa kwepayipi lensimbi enobukhulu obuphelele (njenge- ububanzi noma ubude) kanye ukujiya odongeni, wathi ubukhulu bayo ububanzi ibanzi kakhulu, kusukela encane ububanzi capillary kuze kube amamitha ambalwa ububanzi, ipayipi elikhulu ububanzi.

Amashubhu ensimbi angasetshenziselwa amapayipi, okokusebenza okushisayo, imboni yemishini, ukuhlola kwe-petroleum geological, iziqukathi, imboni yamakhemikhali nezinjongo ezikhethekile.

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

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

I-boiler tube ihlukaniswe ngezigaba ezimbili:I-GB/T3087-2018ishubhu likabhayela eliphakathi neliphansi,I-GB/T5310-2018ishubhu ye-boiler enengcindezi ephezulu. Imikhiqizo yethu eyinhloko ihlanganisa:

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 SA – 213-213 – m, 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.
