    Gusobanukirwa Akamaro k'Umuyoboro wa Gazi Kamere Ufite Ireme: Umuyoboro wa X42 SSAW, ASTM A139 na EN10219

    Gusobanukirwa Akamaro k'Umuyoboro wa Gazi Kamere Ufite Ireme: Umuyoboro wa X42 SSAW, ASTM A139 na EN10219 Ishusho Igaragara
    • Gusobanukirwa Akamaro k'Umuyoboro wa Gazi Kamere Ufite Ireme: Umuyoboro wa X42 SSAW, ASTM A139 na EN10219

    Ibisobanuro bigufi:

    Ku bijyanye no gutwara gazi karemano, imiyoboro y'amazi igira uruhare runini mu gutuma uyu mutungo w'agaciro ugera ku isoko mu buryo bwizewe kandi bunoze.umuyoboro wa gaze karemano Guhitamo ni icyemezo cy'ingenzi kuko bigira ingaruka ku buryo butaziguye ku bwizerwe n'umutekano w'umuyoboro wose wo gukwirakwiza gazi. Muri iyi blog, tuzareba akamaro k'imiyoboro ya gazi karemano nziza, twibanda ku muyoboro wa X42 SSAW, ASTM A139, na EN10219.


    Ibisobanuro birambuye ku gicuruzwa

    Ibirango by'ibicuruzwa

     X42SSAWumuyoboroni ubwoko bw'imiyoboro ya gazi karemano ikoreshwa cyane mu nganda za peteroli na gazi. Ikorwa hakoreshejwe uburyo bwo gusudira imiyoboro y'amazi ikora imiyoboro myiza kandi iramba. Umuyoboro wa X42 SSAW ufite imbaraga nyinshi n'imiterere myiza ya shimi, bigatuma uba mwiza cyane ku bijyanye n'ibikenewe mu gutwara gazi karemano. Urwanya ingese no kwangirika bituma uba amahitamo ya mbere mu mishinga yo kubaka imiyoboro.

     ASTM A139ni ikindi gipimo cy'ingenzi ku miyoboro ya gaze karemano. Ibi bipimo bikubiyemo umuyoboro w'icyuma ugororotse cyangwa uzungurutse ukoreshwa mu gutwara imyuka, umwuka, amazi n'ibindi bintu by'amazi. Umuyoboro wa ASTM A139 uzwiho kwizera no gukora neza igihe kirekire mu bihe bikomeye byo gukora. Iyi miyoboro yagenewe kwihanganira umuvuduko mwinshi n'ihindagurika ry'ubushyuhe, bigatuma iba nziza mu kohereza no gukwirakwiza gaze karemano.

     EN10219ni amahame y’i Burayi agaragaza uburyo bwo gutanga ibikoresho bya tekiniki ku bice by’ubuso by’icyuma kidakoresha ibyuma bikonje n’ibyuma bifite imiterere myiza. Nubwo EN10219 idakozwe ku buryo bwihariye ku miyoboro ya gaze karemano, ibisabwa bikomeye kugira ngo irambe, ikore neza mu buryo bungana n’imiterere ya mekanike bituma iba amahitamo akwiye ku mishinga imwe n’imwe y’imiyoboro ya gaze. Gukoresha imiyoboro ijyanye n’amahame ya EN10219 bishobora kunoza ubuziranenge n’ubuzima bw’imikorere ya sisitemu yawe yo gukwirakwiza gaze karemano.

    Akamaro ko guhitamo imiyoboro ya gaze karemano nziza ntigakwiye kurengerwa. Imiyoboro mibi cyangwa idafite ubuziranenge ishobora guteza ingaruka zikomeye ku bidukikije, umutekano rusange ndetse no ku buryo rusange bwo kubyaza umusaruro gaze. Kubwibyo, ibigo bitanga gaze karemano, abakora imiyoboro n'abayobozi b'imishinga bagomba gushyira imbere ikoreshwa ry'ibikoresho by'imiyoboro byagaragaye kandi byamaze igihe kirekire nka umuyoboro wa X42 SSAW, ASTM A139 na EN10219.

    Umuyoboro wa SSAW

    Muri make,umuyoboro wa gaze karemanoGuhitamo ni ingenzi mu gushushanya no kubaka imiyoboro. Ibitekerezo by’ubuziranenge, nko gukomera kw’ibikoresho, kurwanya ingese, no kubahiriza amahame ngenderwaho y’inganda, bigomba kuyobora inzira yo gufata ibyemezo. Mu guhitamo imiyoboro yizewe kandi izwi, nka X42 SSAW pipeline, ASTM A139, na EN10219, abafatanyabikorwa bashobora kwemeza ko ibikorwa remezo byo gutwara gazi karemano birambye kandi birambye.

    Hanyuma, ni ngombwa gushyira imbere ikoreshwa ry’imiyoboro ya gaze karemano yujuje ibisabwa mu nganda kandi ifite imiterere ikenewe ya mekanike na chimique. Mu guhitamo amahitamo yizewe nka X42 SSAW pipeline, ASTM A139 na EN10219, abakoresha imiyoboro bashobora kwemeza ko sisitemu zabo zo gukwirakwiza gaze karemano zihora zikora neza kandi zitekanye mu gihe kirekire.
