Gusobanukirwa n'akamaro k'umuyoboro mwiza wa gazi Kamere: X42 Umuyoboro wa SSAW, ASTM A139 na EN10219
X42SSAWumuyoboroni ubwoko bwa gazi isanzwe ikoreshwa mubikorwa bya peteroli na gaze.Yakozwe hifashishijwe uburyo bwo gusudira arc bwarohamye butanga imiyoboro myiza kandi iramba.Umuyoboro wa X42 SSAW ufite imbaraga nyinshi n’imiti ihebuje y’imiti, ku buryo ikwiranye n’ibisabwa bikenewe mu gutwara gaze gasanzwe.Kurwanya kwangirika kwangirika no guturika bituma ihitamo bwa mbere imishinga yo kubaka imiyoboro.
ASTM A139ni ikindi gipimo cyingenzi kumiyoboro ya gaze karemano.Ibi bisobanuro bikubiyemo amashanyarazi (arc) yasudutse neza cyangwa azenguruka umuyoboro wicyuma ukoreshwa mugutanga imyuka, amavuta, amazi nandi mazi.Umuyoboro wa ASTM A139 uzwiho kwizerwa no gukora igihe kirekire mubikorwa bikarishye.Iyi miyoboro yashizweho kugirango ihangane n’umuvuduko mwinshi n’imihindagurikire y’ubushyuhe, bigatuma iba nziza mu kohereza gaze gasanzwe no kuyikwirakwiza.

EN10219ni igipimo cyiburayi kigaragaza uburyo bwogutanga tekinike yuburyo bukonje bwubatswe bwubatswe bwubatswe bwubusa bwibice bitarimo amavuta hamwe nicyuma cyiza.Nubwo EN10219 itagenewe cyane cyane imiyoboro ya gaze karemano, ibisabwa byayo kugirango irambe, uburinganire bwuzuye hamwe nubukanishi bituma ihitamo neza mumishinga imwe nimwe ya gaz.Gukoresha imiyoboro ijyanye na EN10219 irashobora guteza imbere ubunyangamugayo nubuzima bwa serivisi ya sisitemu yo gukwirakwiza gaze gasanzwe.
Akamaro ko guhitamo umuyoboro mwiza wa gazi karemano ntushobora kuvugwa.Imiyoboro idahwitse cyangwa itujuje ubuziranenge irashobora guteza ingaruka zikomeye ku bidukikije, umutekano rusange no kwizerwa muri rusange.Kubwibyo, ibikorwa bya gazi karemano, abakoresha imiyoboro nabashinzwe imishinga bagomba gushyira imbere ikoreshwa ryibikoresho byemewe kandi byashizweho neza nka X42 SSAW umuyoboro, ASTM A139 na EN10219.
Muri make,umuyoboro wa gazi karemanoguhitamo nikintu cyingenzi cyo gushushanya imiyoboro no kubaka.Ibitekerezo byiza, nkimbaraga zumubiri, kurwanya ruswa, no kubahiriza amahame yinganda, bigomba gutwara inzira yo gufata ibyemezo.Muguhitamo imiyoboro yizewe kandi izwi, nkumuyoboro wa X42 SSAW, ASTM A139, na EN10219, abafatanyabikorwa barashobora kwemeza ko ubuzima burambye n’umutekano by’ibikorwa remezo bitwara gaze gasanzwe.
Hanyuma, ni ngombwa gushyira imbere ikoreshwa ry'imiyoboro ya gazi yo mu rwego rwo hejuru yujuje ubuziranenge bw'inganda kandi ifite ibikoresho bya mashini na chimique bikenewe.Muguhitamo amahitamo yizewe nkumuyoboro wa X42 SSAW, ASTM A139 na EN10219, abakora imiyoboro barashobora kwemeza ubunyangamugayo bwigihe kirekire numutekano wa sisitemu yo gukwirakwiza gaze gasanzwe.
