Spiral Submerged Arc Welded Umuyoboro Muri API 5L Umurongo wa Porogaramu

Spiral Submerged Arc Welded Umuyoboro Muri API 5L Imiyoboro Yumurongo Porogaramu Igaragaza Ishusho

Ibisobanuro bigufi:

Mu rwego rwo gutwara peteroli na gaze, gukoresha imiyoboro ya arc izengurutswe na arc bigenda byiyongera cyane cyane mu iyubakwa rya sisitemu ya API 5L.Umuyoboro wa SSAW (arc welded arc welded) uzwiho imbaraga nyinshi, kuramba no guhinduka, bigatuma uba usaba ibisabwa nkinganda za peteroli na gaze.

UwitekaUmuyoboro wa API 5Ligipimo ni ibisobanuro byateguwe n'Ikigo cy'Abanyamerika gishinzwe peteroli (API) cyo gutwara gaze gasanzwe, peteroli n'amazi.Irerekana ibikenerwa mu gukora imiyoboro isudira kandi ishyiraho umurongo ngenderwaho uhamye w'ubwiza, imbaraga n'imikorere y'iyi miyoboro.

Umuyoboro wa SSAWikorwa hifashishijwe uburyo bwo gusudira arc bwarohamye burimo gukora igiceri cyicyuma muburyo buzengurutse hanyuma ugakoresha arc yo gusudira kugirango uhuze impande za coil hamwe.

Imwe mu nyungu zingenzi zo gukoresha spiral yarengeje arc welded umuyoboro wa API 5L umurongo wububiko nubushobozi bwabo bwo kwihanganira urwego rwo hejuru rwumuvuduko wimbere ninyuma.Ibi ni ingenzi cyane mu nganda za peteroli na gaze, aho imiyoboro ihura n’ibihe bikabije n’imitwaro iremereye.Kubaka cyane imiyoboro ya SSAW ituma biba byiza imiyoboro ikora ku muvuduko mwinshi n'ubushyuhe, itanga igisubizo cyizewe kandi kirambye cyo gutwara ibintu bifite agaciro.

Byongeye kandi, ubworoherane bwa spiral yarengewe arc welded umuyoboro woroshye kuyishyiraho no kuyitunganya, bigatuma ihitamo neza kubikorwa byubaka imiyoboro.Ubushobozi bwabo bwo guhinduka no guhuza imiterere karemano yubutaka bikuraho ibikenerwa byinganda zihenze kandi zitwara igihe kandi bikagabanya ibyago byo kumeneka no gutsindwa.Byongeye kandi, ubuso bwimbere bwimiyoboro ya SSAW bugabanya guterana no guhungabana, bigatuma habaho kugenda neza no gukoresha ingufu nke.

Muri make, gukoresha imiyoboro ya arc izengurutswe imiyoboro ya API 5L itanga imiyoboro itanga urukurikirane rwibyiza bituma iba amahitamo ashimishije mubikorwa bya peteroli na gaze.Imbaraga zabo, kuramba no guhinduka bituma biba byiza gukoreshwa mubidukikije bisabwa, mugihe ubworoherane bwo kwishyiriraho nibisabwa bike bitanga igisubizo cyigiciro cyimishinga yo kubaka imiyoboro.Mugihe icyifuzo cyo gutwara ibintu byizewe, neza bya peteroli, gaze gasanzwe namazi bikomeje kwiyongera, akamaro k'umuyoboro wogosha arc weld washyizwe mumurongo wa API 5L ntushobora kuvugwa.Nibikorwa byayo byagaragaye kandi bihindagurika,Umuyoboro wuzuye arc umuyoboroyashyizweho kugirango ikomeze kuba igice cyingenzi cyibikorwa remezo biteza imbere ubukungu bwisi.
