Uruganda ruhendutse Ubushinwa Bwiza Bwiza Buringaniye bwa Carbone Icyuma gisudira
Incamake
"Igenzura ibipimo ukurikije ibisobanuro, werekane ingufu ukurikije ubuziranenge". Uruganda rwacu rwihatiye gushyiraho abakozi bakora neza kandi ruhamye kandi rushakisha uburyo bwiza bwo kugenzura ubuziranenge bwiza bwa Carbone Steel Welded Pipes. Ubwiza bwiza ni ukubaho kwuruganda, kwibanda kubyo abakiriya bakeneye ni isoko yo kubaho kwiterambere no gutera imbere, Dukurikiza ubunyangamugayo n imyizerere isumba iyindi yo kwizera, guhiga imbere yawe!
Ku miyoboro ya karuboni isudira, hari tekinoroji 2 yingenzi igomba kumenya ko ari ERW (amashanyarazi arwanya amashanyarazi) na SAW (submerge arc weld). Imiyoboro yakoresheje ubwo buhanga byombi ikoreshwa cyane cyane mu nganda za peteroli mu gutwara peteroli na gaze, ariko byose bifite inyungu zabyo, bityo imikoreshereze ni itandukanye.
Umuyoboro wa ERW wakozwe mu isahani yicyuma, hariho icyuma kimwe gusa cyo gusudira, kandi kubera ko umurongo wo gusudira wumuyoboro wa ERW ukomoka kumuyoboro wa nyina, ntukeneye ibicuruzwa bigurishwa, bityo umutungo wubukanishi nibyiza cyane. Kandi kubera ibiranga umusaruro mwinshi, igiciro gito, kuzigama ibikoresho, no gukoresha automatike yoroshye, gereranya numuyoboro wa SAW, umuyoboro wa ERW numuyoboro wibyuma ufite imikorere igezweho, uyobora ubuziranenge kandi ugereranije nubukungu mubijyanye no kubika peteroli na gaze no gutwara abantu. By'umwihariko ukurikire iterambere ryikoranabuhanga, ubuziranenge niba umurongo wo gusudira urimo urushaho kuba mwiza, ukoresheje ikoranabuhanga rishya, ikigamijwe ni ugukuraho imihangayiko, koroshya no gutunganya imiterere, no kunoza imiterere yubukanishi bwa zone yibasiwe nubushyuhe. Ubu bwoko bwa ERW umuyoboro ntushobora gutandukanywa gusa, ariko kandi na coefficient yo gusudira igera kuri 1, ikamenya guhuza imiterere yakarere kegereye hamwe nibikoresho fatizo.
SAW ikoranabuhanga rigezweho ni ryinshi cyane, kandi flux layer irinda gutakaza ubushyuhe bwihuse kandi ikabishyira ahantu hagurishwa. Gusudira arc gusudira bifite ubudodo bwo hejuru bwo gusudira, gukora neza, nta mucyo wa arc numwotsi muke. Imiyoboro ya arc isudira ibyuma ikoreshwa cyane mubikoresho byumuvuduko, ibyuma bifata imiyoboro, imirishyo, inkingi, amazi yumuvuduko ukabije, hamwe nimishinga yububiko. Ariko mu bihugu bikomoka kuri peteroli mu bihugu byateye imbere, umuyoboro wa SAW ntiwemerewe kubera ko ubwayo igarukira, gusa mu Bushinwa umuyoboro wa SAW uracyemerewe mu nganda za peteroli ntarengwa.
Igiciro cyiza kandi cyiza "ni amahame yubucuruzi. Niba ushishikajwe nibicuruzwa byacu nibisubizo cyangwa ufite ikibazo, menya neza ko utwiyambaza. Turizera ko tuzashyiraho umubano wubufatanye nawe mugihe cya vuba.
Gusaba
Irakoreshwa Cyane kubice byingufu nigitutu, no mubikorwa rusange ibyuka, amazi, gaze numuyoboro wikirere.
