    Ibyiza byo gukoresha imiyoboro y'icyuma ikoreshwa mu mazi yo munsi y'ubutaka mu buryo bwa Spiral submerged Arc Welded

    Ibyiza byo gukoresha imiyoboro y'icyuma ikoze mu mazi yo munsi y'ubutaka, ikoresheje spiral submerged arc welded, ikoreshwa mu miyoboro y'amazi yo munsi y'ubutaka.
    • Ibyiza byo gukoresha imiyoboro y'icyuma ikoreshwa mu mazi yo munsi y'ubutaka mu buryo bwa Spiral submerged Arc Welded

    Ibisobanuro bigufi:

    Mu gushyiraho imiyoboro y'amazi yo munsi y'ubutaka, ni ngombwa guhitamo ubwoko bw'imiyoboro ikwiye kugira ngo irambe kandi irambe. Amahitamo akunzwe ku miyoboro y'amazi yo munsi y'ubutaka ni umuyoboro ukozwe mu buryo bwa spiral welded, uzwi kandi ku izina rya SSAW steel pipe.


    Ibisobanuro birambuye ku gicuruzwa

    Ibirango by'ibicuruzwa

     Umuyoboro w'icyuma wa SSAWni ubwoko bw'umuyoboro ukozwe mu buryo bwa spiral ukoreshwa mu bintu bitandukanye, harimo n'imiyoboro yo mu mazi. Uburyo bwawo bwihariye bwo gusudira butanga imiyoboro minini ifite ubugari buhamye, bigatuma uba mwiza mu gutwara amazi yo munsi y'ubutaka.

    Imwe mu nyungu z'ingenzi zo gukoresha umuyoboro w'icyuma ukozwe mu cyuma gikozwe mu buryo bwa spiral submerged arc welded ku miyoboro y'amazi yo munsi y'ubutaka ni uko ukomera cyane kandi uramba. Uburyo bwo gusudira mu buryo bwa spiral butuma umuyoboro ukomeye kandi wizewe ushobora kwihanganira igitutu n'uburemere bwo gutwikirwa munsi y'ubutaka. Ubu bukomere ni ingenzi mu gukumira amazi no kwemeza ko imiyoboro y'amazi ihora ikora neza igihe kirekire.

    Byongeye kandi, umuyoboro w'icyuma wa SSAW urwanya ingese, bigatuma uba amahitamo meza yo gukoreshwa munsi y'ubutaka aho imiyoboro ihura n'ubushuhe n'ibindi bintu bifitanye isano n'ibidukikije. Uku kudakomera kw'ingese bifasha kongera igihe cy'imiyoboro yawe kandi bikagabanya gukenera kuyisana no kuyisana kenshi.

    Umuyoboro w'amazi yo munsi y'ubutaka

    Indi nyungu yo gukoresha umuyoboro w'icyuma ukozwe mu buryo bwa spiral ukoresheje arc welded ku miyoboro yo munsi y'ubutaka ni uko woroshye kuwukoresha no kuwukoresha. Uburyo bwo kuwukoresha bushobora gukora imiyoboro y'uburebure butandukanye, bigatuma uba ukwiriye gukoreshwa mu miyoboro y'amazi itandukanye. Byongeye kandi, ubworoherane bw'umuyoboro w'icyuma wa SSAW butuma woroha kuwushyiraho no kuwukoresha, cyane cyane mu turere dufite ubutaka bugoye cyangwa imbogamizi.

    a. Uburyo bwo gukuraho ogisijeni mu mubiri bugenwa ku buryo bukurikira:

    FF: Icyuma cyapfuye cyose kirimo ibintu bihuza azote mu rugero ruhagije kugira ngo gifatanye azote ihari (urugero: 0.020% by'Al yose cyangwa 0.015% by'Al ishongesha).

    b. Agaciro ntarengwa ka azote ntigakurikizwa iyo imiterere y’imiti igaragaza ko Al yose hamwe na 0.020% hamwe na Al/N ya 2:1, cyangwa niba hari ibindi bintu bihagije bihambira kuri N. Ibintu bihambira kuri N bigomba kwandikwa mu nyandiko y’igenzura.

    Uretse gukomera, kuramba, no koroherwa, imiyoboro y'icyuma ikoreshwa mu buryo bwa spiral ihendutse ihendutse ugereranyije n'ubundi bwoko bw'imiyoboro. Uburyo bwo gusudira mu buryo bwa spiral bugabanya ikiguzi cyo gukora, bigatuma iba amahitamo ahendutse ku mishinga minini y'imiyoboro y'amazi. Kuba imiyoboro y'icyuma ya SSAW iramba igihe kirekire kandi ikaba idasaba ubwishingizi buke, nabyo bigira uruhare mu kuzigama amafaranga muri rusange mu gihe cyose umuyoboro w'amazi umara.

    Umuyoboro wa SSAW

    Muri rusange, hari ibyiza byinshi byo gukoresha imiyoboro y'icyuma ikoreshwa mu mazi yo munsi y'ubutaka, harimo imbaraga nyinshi, kuramba, kurwanya ingese, koroherana no kugabanya ikiguzi. Iyi miterere ituma iba amahitamo yizewe kandi afatika yo gutwara abantu mu mazi yo munsi y'ubutaka, haba mu bikorwa remezo by'umujyi, mu nganda, cyangwa mu buhinzi.

    Muri make, iyo bigeze ku guhitamo umuyoboro mwiza kurusha iyindiku miyoboro y'amazi yo munsi y'ubutaka, umuyoboro w'icyuma ukozwe mu buryo bwa spiral ukoresheje arc welded ni wo mahitamo meza. Imiterere yawo ikozwe mu buryo bwa spiral-welded itanga imbaraga, kuramba no kurwanya ingese bikenewe kugira ngo ikore neza igihe kirekire, mu gihe ubworoherane bwayo n'uburyo ihendutse bituma iba amahitamo meza ku mishinga y'imiyoboro y'amazi y'ingano zose. Uhisemo umuyoboro w'icyuma ukozwe mu buryo bwa spiral ukoresheje arc welded, ushobora kwemeza ko imiyoboro yawe y'amazi yo munsi y'ubutaka izakomeza kuba inyangamugayo kandi irambye, ikaguha amahoro yo mu mutima no kwizera uburyo bwawe bwo gukoresha amazi.
