1.Gutanga imbaraga zisumba zombi austenitis na 22% Cr Duplex Stainless Steel UNS S32760 (F55) ikwiranye nuburyo butandukanye bukoreshwa mu nganda nka peteroli na gaze, CPI (Inganda zitunganya imiti), hamwe n’ibidukikije byo mu nyanja.

UNS S32760 (F55 / 1.4501) yanditse muri NACE MR 01 75 kubikorwa bya serivisi kandi imaze kubona ASME Icyemezo cya progaramu ya Vessel.

urwego rwimbaraga ukoresheje uburyo bworoshye bwo kuvura ubushyuhe kuri RH 950 na TH 1050.Imbaraga zidasanzwe zidasanzwe za Imiterere CH 900 zitanga ibyiza byinshi aho guhindagurika no gukora byemewe. Mu bushyuhe bwacyo butunganijwe, iyi mavuta itanga imiterere idasanzwe yubushyuhe bugera kuri 900 ° F (482 ° C).
