    Umuyoboro usuye ibyuma by'imbaraga zidahera no gukora neza ATTM A252

    Umuyoboro usuye ibyuma by'imbaraga zidahenganywa na ASTM ATTM A252 Ishusho
    • Umuyoboro usuye ibyuma by'imbaraga zidahera no gukora neza ATTM A252

    Ibisobanuro bigufi:

    Iri shusho ni ugutanga amahame yo gukora kuri sisitemu ya pieline kugirango ashyireho amazi, gaze namavuta mubikoresho bya peteroli na gazi bisanzwe.

    Hariho urwego rwibicuruzwa bibiri, psl 1 na PSL 2 bifite ibyo basabwa gutegera kuri karubone, kuvuza imbaraga, imbaraga ntarengwa nimbaraga ndende.

    Kumenyekanisha:

    Ku bijyanye n'iterambere ry'ibikorwa, sisitemu ya pieline ni ikintu cyingenzi kigira uruhare runini munganda zitandukanye. Ukoresheje ibikoresho nubuhanga muburyo bwubwubatsi bugira iherezo, imbaraga no kwizerwa, kandiSpiral Icyuma Icyuma Astm A252ni ku isonga ryiterambere ryikoranabuhanga. Muri iyi blog, tuzareba neza imico idasanzwe ninyungu ziyi miyoboro idasanzwe yabaye intambara mumishinga yo kubaka igezweho.

    Imbaraga zidahesha imbogamizi n'imbwa:

    ASTM A252Icyuma gisukuyeikozwe mubyuma birebire bihura nibipimo bya ASTM A252. Imbaraga zisanzwe zemewe nimbaraga zisumba izindi mipape, bigatuma bakwirakwiriye kubisabwa bitandukanye birimo kwanduza peteroli na gaze, uruzitiro nibikorwa remezo byamazi. Inzemu zongewe zongera imbaraga no kurwanya imiyoboro yingabo zo hanze, zemeza ko zishobora kwihanganira imiti yimihato yo kumurika nigihe cyikirere.

    Imikorere myiza kandi uko ikora neza:

    Imwe mu nyungu z'ibanze za ASTM A252 umuyoboro w'icyuma usukuye ni imikorere ye yo hejuru mu kwishyiriraho no gukoresha. Igishushanyo cyacyo cyoroshye biroroshye gutwara no gupima kubera uburemere bwicyo cyoroshye ugereranije nibindi bikoresho byungurura. Byongeye kandi, guhinduka ko ibyo bikoresho byorohereza no kunama, kugabanya ibisabwa kugirango bihuze kandi bihuze. Ntabwo aribyo gusa umwanya, bikagabanya cyane ibiciro byo kwishyiriraho, bigatuma ubwoko bwumutuku igisubizo cyiza kubikorwa bitandukanye.

    Umuyoboro wa Spiral Welding Uburebure Kubara

    Yongereye Kurwanya Ibirori:

    RORRISONION ni ikibazo gikomeye mugushushanya sisitemu, cyane cyane munganda zikemura imiti n'ibintu byangiza. ASTM A252 Ibipimo byemeza ko imiyoboro isukuye isesuye ibyuma bigaragaza ihohoterwa ryiza. Iyi miyoboro ifite aho gukingira nka epoxy cyangwa zinc ikora nkimbogamizi ku bakozi ba ruswa, bagura ubuzima bwabo bwo gukora kandi kugabanya ibiciro byo kubungabunga. Iyi mikorere ni ingirakamaro cyane muburyo bwo munsi yubutaka cyangwa offshore aho imiyoboro ihura nibidukikije bikaze.

    Ubushobozi bukomeye:

    Ikindi kintu cyingenzi kiranga ASTM A252 umuyoboro usukuye ibyuma nubushobozi bwiza bwo gutwara imitwaro. Ikoranabuhanga mu gusudira ryakoreshejwe muburyo bwo gukora ritezimbere imbaraga nubushobozi bwo kwihanganira imitwaro iremereye. Byakoreshwa mu kubaka ikiraro, urufatiro rw'ibigo cyangwa imiyoboro yo munsi y'ubutaka, iyi miyoboro itanga ubunyangamugayo buhebuje, kugabanya ibyago byo kunanirwa no guharanira umutekano mu mishinga miremire y'ibikorwa remezo.

    Gukomeza ibidukikije:

    Mubihe iyo kurengera ibidukikije ari impungenge ku isi, uhitamo ibikoresho byubaka ni ngombwa. Icyuma gisubukura ibyuma A252 byubahiriza ibikorwa birambye byubaka bitewe no kuramba no gutumya. Imiyoboro ifite ubuzima burebure kandi irashobora gutungura byoroshye kumpera yubuzima bwabo, kugabanya ibikenewe byo gukuramo ibikoresho mugihe bigabanya imyanda hamwe nubwiyuha.

    Mu gusoza:

    Icyuma gisubukura ibyuma A252 cyahinduye inganda za pipine hamwe n'imbaraga zisumba izindi, kuramba no gukora neza. Iyi miyoboro ihura cyangwa irenga ibipimo ngenderwaho, bibagezaho amahitamo ya mbere munganda nyinshi. Ubushobozi bwabwo butanga imitwaro hamwe no kurwanya ruswa kwemeza iterambere rirambye ryimishinga y'ibikorwa remezo no kugira uruhare mu iterambere ry'inganda z'isi. Mugukoresha iyi miyoboro, imishinga yo kubaka irashobora guhitamo imikorere, kugabanya ibiciro no kureba niba byimazeyo kwizerwa mugihe ukurikiza ibidukikije.
