I-alloy tube uhlobo lwe-seamless steel tube, ehlukaniswe nge-structural seamless tube kanye ne-high pressure heat alloy tube. Ehluke kakhulu ezindinganisweni zokukhiqiza kanye nemboni yama-alloy tubes, ama-alloy tubes a-annealed kanye ne-tempered alloy ashintsha izakhiwo zemishini. Ihlangabezana nezimo zokucubungula ezidingekayo. Ukusebenza kwayo kuphakeme kunokwepayipi lensimbi elijwayelekile elingenamthungo, ukwakheka kwamakhemikhali kuqukethe i-Cr eningi, ngakho-ke inokumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi kanye nokumelana nokugqwala. Ama-carbon tubes ajwayelekile angenamthungo aqukethe i-alloy noma inani elincane le-alloy. I-alloy tube isetshenziswa kabanzi ku-petroleum, i-aerospace, amakhemikhali, amandla kagesi, i-boiler, i-military kanye neminye imboni, ngoba izakhiwo zemishini ze-alloy tube ziyahlukahluka, kulula ukuzilungisa.

Ipayipi lensimbi ye-alloy lisetshenziswa kakhulu esitshalweni sikagesi, esitshalweni sikagesi senuzi, kubhoyila enomfutho ophezulu, ku-superheater enokushisa okuphezulu, ku-reheater kanye nakwamanye amapayipi nemishini enomfutho ophezulu kanye nokushisa okuphezulu. Lenziwe ngensimbi yekhabhoni esezingeni eliphezulu, insimbi yokwakheka kwe-alloy kanye nensimbi engagqwali engamelani nokushisa ngokugoqa okushisayo (ukukhipha, ukunwebeka) noma ukugoqa okubandayo (ukudweba).
