I-NI90Cr10, eyaziwa nangokuthi i-Nichrome 90 noma i-NiCr 90/10, iyingxubevange esebenza kahle kakhulu enikeza ukumelana okuhle namazinga okushisa aphezulu kanye nokugqwala. Inezinga eliphezulu lokuncibilika elicishe libe ngu-1400°C (2550°F) futhi lingagcina amandla ayo nokuzinza ngisho nasezingeni lokushisa elingaphezu kuka-1000°C (1832°F).

Le alloy ivamise ukusetshenziswa ezinhlelweni ezidinga izinto zokushisisa, njengasezithandweni zezimboni, ohhavini, nezinto zokushisisa. Ibuye isetshenziswe ekukhiqizeni ama-thermocouples, asetshenziselwa ukukala izinga lokushisa ezinqubweni ezihlukahlukene zezimboni.

I-NI90Cr10 inokumelana okuhle kakhulu ne-oxidation, okuyenza isebenziseke ikakhulukazi ezindaweni ezinezinga lokushisa eliphezulu lapho ezinye izinto zingagqwala ngokushesha futhi ziwohloke. Ibuye ibe nezakhiwo ezinhle zemishini, njengamandla aphezulu okudonsa kanye ne-ductility enhle, okwenza kube lula ukwakha nokuma.

Uma kukhulunywa ngamapayipi enziwe ngale ngxubevange, asetshenziswa ngokujwayelekile ezinhlelweni lapho izinga lokushisa eliphezulu nokugqwala kukhona khona, njengasezimbonini zokucubungula amakhemikhali, i-petrochemical, nezimboni zokuphehla amandla. Izici ezithile zepayipi, njengosayizi walo, ukujiya kodonga, kanye nesilinganiso sokucindezela, kuzoncika ekusetshenzisweni okuhlosiwe kanye nezidingo ezithile zephrojekthi.

Amapayipi e-NI90Cr10 ngokuvamile asetshenziswa ezinsizeni lapho izinga lokushisa eliphezulu nokugqwala kukhona khona, njengasezimbonini zokucubungula amakhemikhali, i-petrochemical, nezimboni zokuphehla ugesi. Lawa mapayipi aziwa ngokumelana kwawo okuhle kakhulu ne-oxidation kanye nokugqwala, okuwenza alungele ukusetshenziswa ezindaweni ezibandakanya izixazululo ezine-asidi noma ze-alkaline. Ezinye zezicelo ezithile zamapayipi e-NI90Cr10 zifaka:

Ukucutshungulwa kwamakhemikhali: Amapayipi e-NI90Cr10 avame ukusetshenziswa ekusetshenzisweni kwamakhemikhali lapho izinga lokushisa eliphezulu kanye nezimo ezigqwalile zikhona. Lawa mapayipi angasetshenziswa ukuthutha amakhemikhali aqala ukugqwala futhi angakwazi ukumelana nokuchayeka kuzixazululo ezineasidi noma ezine-alkali.
I-Petrochemical: Amapayipi e-NI90Cr10 nawo asetshenziswa embonini ye-petrochemical, lapho asetshenziswa khona ekukhiqizeni uwoyela negesi. Ziyakwazi ukumelana namazinga okushisa aphezulu nokucindezela futhi zimelana nokugqwala, okuzenza zilungele ukusetshenziswa ezindaweni ezinokhahlo.
Ukukhiqiza amandla: Amapayipi angu-NI90Cr10 asetshenziswa ekuphehleni ugesi njengakuma-turbines egesi kanye nezinjini zesitimu. Lawa mapayipi angakwazi ukumelana nezimo ezishisa kakhulu nezinomfutho ophezulu futhi amelana nokugqwala, okuwenza alungele ukusetshenziswa ezitshalweni zikagesi.
