Suzuma ikoreshwa rya Elgiloy cyangwa MP35N kumpeta ya spiral mumashanyarazi ya ultra-high-pressure.

Elgiloy (Co-Cr-Ni alloy) na MP35N ni cobalt ishingiye kuri 'super-alloys' ikoreshwa mubisabwa cyane mu mazi no mubuvuzi. Zitanga imbaraga zingana na ksi 300 hamwe no kurwanya bidasanzwe hydrogène sulfide ($ H_2S $) namazi yo mu nyanja. Ku mpeta izenguruka mu mwobo wo mu nyanja, ibyo bikoresho bitanga imbaraga zishoboka zose 'kwizirika' hamwe n’ubushobozi bwo gusunika mu gihe zidakingiwe na ruswa ishobora kwangirika hagati y’impeta idafite ingese n’amazu ya karuboni. Igiciro cyabo kinini gifite ishingiro mubidukikije 'zeru-gutsindwa' aho ikiguzi cyo gutabara (urugero, ubutumwa bwa ROV) kirenze ikiguzi cyibintu byinshi byateganijwe.
