Flange bolts: guhanga udushya? 

Iyo wunvise 'birambye' na 'flange bolts' mu nteruro imwe, abantu benshi mubucuruzi barasebya cyangwa bagatangira kuvuga kubyerekeranye no gutunganya ibyuma bishaje. Ngiyo umutego usanzwe-gutekereza kuramba ni ibintu byanyuma byubuzima. Ariko guhera hasi, mugukora no gukoresha, hari byinshi kuri byo. Ntabwo ari icyatsi kibisi gusa; ni ukumenya niba ikintu kibi kimara igihe kinini mukibazo, ikoresha imbaraga nke mugushiraho, cyangwa ntigikeneye gusimburwa buri mwaka. Aho niho ikiganiro nyacyo kigomba kuba.

Guhitamo Ibikoresho Birenze Ibigaragara

Umuntu wese arasimbuka kutagira umwanda kugirango arwanye ruswa, abita guhitamo 'icyatsi'. Ariko imbaraga zingirakamaro zo kubyara austenitike yo mu rwego rwo hejuru idafite umwanda, tuvuge 316, ni nini. Nabonye spes aho ubushyuhe-bushyushye bwa karubone ibyuma bya karubone flange bolt, yometse neza, yakoraga akazi mubidukikije bikabije mumyaka 15, nta icyuya. Ikirenge cya karubone kiva mubikorwa cyari gito. Guhanga udushya ntabwo buri gihe ari ibintu byiza bishya; rimwe na rimwe ni ibijyanye no gukoresha ubwenge kubihari. Twakoresheje icyiciro cyikizamini cyumushinga wingirakamaro ku nkombe, duhuza A4-80 isanzwe hamwe na sisitemu ya zinc-aluminium flake yo gutwikira kurwego rwo hasi.
