Ipayipi lebhoyila livulekile kuzo zombili izinhlangothi futhi linengxenye engenalutho, ubude kanye nendawo ezungezile yensimbi enkulu, ngokwezindlela zokukhiqiza ingahlukaniswa ibe yipayipi lensimbi elingenamthungo kanye nepayipi lensimbi elihlanganisiwe, incazelo yepayipi lensimbi enobukhulu obujwayelekile (njengobubanzi noma ubude) kanye nobukhulu bodonga, kusho ububanzi bayo obukhulu kakhulu, kusukela ku-capillary encane yobubanzi kuze kube ngamamitha amaningana ububanzi, ipayipi elikhulu lobubanzi.

Amapayipi ensimbi angasetshenziswa ekufakeni amapayipi, imishini yokushisa, imboni yemishini, ukuhlola i-petroleum geological, izitsha, imboni yamakhemikhali kanye nezinjongo ezikhethekile.

(1) Insimbi yesakhiwo sekhabhoni esezingeni eliphezulu engu-20G, 20MnG, 25MnG.

(2) Isakhiwo sensimbi ye-alloy 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njll.

I-boiler tube ihlukaniswe ngezigaba ezimbili:GB/T3087-2018ishubhu yebhoyila yokucindezela okuphakathi nokuphansi,GB/T5310-2018ishubhu lebhoyila elinomfutho ophezulu. Imikhiqizo yethu eyinhloko ifaka:

I-ASTMA210(A10M)-2012Ibhoyila yensimbi yekhabhoni ephakathi nendawo kanye nepayipi lensimbi elingenamthungo le-superheater, impahla eyinhloko yi-SA210 GrA1,SA210GrC;

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