Gusobanukirwa akamaro k'umuyoboro wa gazi karemano: X42 Ssaw Umuyoboro, ASTM A139 na EN10219
X42Ssawumuyoboroni ubwoko bwumuyoboro wa gaze karemano ukoreshwa muri peteroli na gaze. Yakozwe hakoreshejwe inzira yo kurengana arc itanga imiyoboro myiza kandi iramba. X42 Umuyoboro wa Ssaw ufite imbaraga nyinshi hamwe nimbaraga nziza za mitique yimiti, bituma bikwiranye nibisabwa bisabwa ubwikorezi busanzwe. Kurwanya cyane kuri ruswa no gucikamo bituma habaho amahitamo yambere yimishinga yubwubatsi.
ASTM A139nubundi busanzwe kuri gaze ya gaze. Iyi shusho yerekana electropsion (arc) gusudira cyangwa spiral Seam steel ibyuma ikoreshwa mugutanga imyuka, inyamanswa, amazi nizindi mazi. ASTM A139 umuyoboro uzwiho kwizerwa no gukora igihe kirekire munsi yimikorere ikaze. Iyi miyoboro yagenewe kwihanganira imikazo yo hejuru nubushyuhe bwihindagurika, bikaba byiza kubikorwa byo kwanduza gaze no gukwirakwiza.

En10219ni urwego rwiburayi rugaragaza imiterere ya tekiniki yo gutanga tekinike yo gusudira-ubukonje bwibice bitarimo bidahwitse hamwe nicyuma cyiza. Nubwo EN10219 itaba igana ku miyoboro gaze ya gaze, ibisabwa byayo bikoreshwa mu kuramba, guhuza ibipimo bitandukanye hamwe na moshini zituma ihitamo neza imishinga imwe y'imishinga. Gukoresha imiyoboro yubahiriza amahame ya EN10219 birashobora kuzamura ubunyangamugayo rusange nubuzima bwa serivisi ya sisitemu yo gukwirakwiza gaze.
Akamaro ko guhitamo umuyoboro wa gazi karemano ntushobora gukomeye. Imiyoboro ikennye cyangwa imiyoboro idahwitse irashobora gutera ingaruka zikomeye kubidukikije, umutekano rusange hamwe nubwirinzi rusange bwibikoresho bya gaze. Kubwibyo, ibikorwa bisanzwe bya gaze, abashinzwe imiyoboro hamwe nabayobozi bashinzwe imishinga bagomba gushyira imbere ikoreshwa ryibikoresho byagaragaye kandi byashizweho neza nka x42 ssaw, ASTM A139 na EN10219.
Muri make,Umuyoboro wa gaziGuhitamo ni ikintu cyingenzi cyo gushushanya no kubaka. Ibitekerezo byiza, nk'imbaraga z'umubiri, kurwanya ruswa, no kubahiriza ibipimo ngenderwaho, bigomba gutwara ibyemezo byo gufata ibyemezo. Muguhitamo imiyoboro yizewe kandi uzwi, nka X42 Ssaw, ASTM A139, na EN10219, abafatanyabikorwa barashobora kwemeza imirwano n'imizigo remezo remezo byo gutwara ibintu bisanzwe.
Hanyuma, ni ngombwa kugira uruhare mu gukoresha imiyoboro imeze neza ihuye n'ibipimo ngenderwaho kandi bifite imashini nkenerwa n'imiti. Muguhitamo amahitamo yizewe nka X42 Ssaw Ssaw, ASTM A139 na EN10219, abatwara imigezi barashobora kwemeza ubunyangamugayo n'umutekano bya sisitemu yo gukwirakwiza gaze.
