Imiyoboro ya Arc Welded muri API 5L Line Pipe ikoreshwa mu buryo bwa Spiral Submerged Arc Welded muri API 5L Line Pipe.

Umuyoboro wa Arc Welded muri API 5L Line Pipe Porogaramu Ishusho Igaragara

Ibisobanuro bigufi:

Mu rwego rwo gutwara peteroli na gaze, ikoreshwa ry'imiyoboro ikoreshwa mu byuma bicukura imiyoboro irimo uruziga ririmo kwiyongera cyane, cyane cyane mu kubaka imiyoboro ya API 5L. Umuyoboro wa SSAW (ufite uruziga rwometseho imiyoboro) uzwiho gukomera kwawo, kuramba no koroha, bigatuma uba mwiza cyane mu bikorwa bigoye nko mu nganda za peteroli na gaze.

ItsindaUmuyoboro w'umurongo wa API 5Libipimo ngenderwaho ni ibyashyizweho n'Ikigo cy'Abanyamerika gishinzwe Peteroli (API) mu gutwara gaze karemano, peteroli n'amazi. Bigaragaza ibisabwa mu gukora imiyoboro y'ibyuma ishongeshejwe kandi bigashyiraho amabwiriza akaze yerekeye ubwiza, imbaraga n'imikorere y'iyi miyoboro.

Umuyoboro wa SSAWikorwa hakoreshejwe uburyo bwo gusudira arc iri munsi y’amazi busaba gukora coil y’icyuma mu ishusho izengurutse hanyuma hagakoreshwa arc yo gusudira kugira ngo impande z’arc zifatanye.

Imwe mu nyungu z'ingenzi zo gukoresha umuyoboro wa arc welded ukoresheje spiral submiked arc mu miyoboro ya API 5L ni ubushobozi bwawo bwo kwihanganira igitutu cyo hejuru cy'imbere n'inyuma. Ibi ni ingenzi cyane mu nganda za peteroli na gaze, aho imiyoboro ihura n'imimerere mibi n'imitwaro iremereye. Kuba imiyoboro ya SSAW ikomeye bituma iba nziza ku miyoboro ikora ku gitutu n'ubushyuhe bwinshi, bitanga igisubizo cyizewe kandi kirambye cyo gutwara umutungo w'agaciro.

Byongeye kandi, uburyo bworoshye bwo gushyiramo imiyoboro icukurwa mu cyuma gishyushye butuma byoroha kuyishyiraho no kuyibungabunga, bigatuma iba amahitamo meza ku mishinga yo kubaka imiyoboro. Ubushobozi bwayo bwo kwiyoroshya no guhuza n’imiterere karemano y’ubutaka bukuraho gukenera gukora ibikoresho bihenze kandi bitwara igihe kinini kandi bigabanya ibyago byo kuva amazi no kwangirika. Byongeye kandi, ubuso bworoshye bw’imbere bw’imiyoboro ya SSAW bugabanya gukururana no kuzungazunga, bigatuma amazi atembera neza kandi ingufu zigakoreshwa nke.

Muri make, ikoreshwa ry'imiyoboro ikoze mu buryo bwa API 5L itanga inyungu nyinshi zituma iba amahitamo meza ku nganda za peteroli na gaze. Ingufu zayo, kuramba kwayo no koroha kwayo bituma iba nziza mu bidukikije bigoye, mu gihe uburyo bworoshye bwo kuyishyiraho no kuyisana bidasaba ubufasha bwinshi bitanga igisubizo gihendutse ku mishinga y'ubwubatsi bw'imiyoboro. Kubera ko icyifuzo cyo gutwara peteroli, gaze karemano n'amazi byizewe kandi neza gikomeje kwiyongera, akamaro k'imiyoboro ikoze mu buryo bwa API 5L ntikagombye kurengerwa. Bitewe n'imikorere yayo myiza n'ubushobozi bwayo,umuyoboro w'uruziga ruri munsi y'uruzigabiteganijwe ko bizakomeza kuba igice cy'ingenzi cy'ibikorwa remezo biyobora ubukungu bw'isi.
