Kohereza ibicuruzwa mu Bushinwa Icyuma gisudira Umuyoboro wa Carbone
Kohereza hanzeUmuyoboro wa Carbone,Umuyoboro w'icyuma,Umuyoboro muto wa Carbone,imiyoboro isudira, kuva mu Bushinwa. Isosiyete yacu izobereye mu kohereza imiyoboro y'icyuma isudira hamwe n'imiyoboro y'icyuma idafite kashe. Toni ibihumbi n'ibihumbi by'imiyoboro isudira yoherezwa hanze buri mwaka. Imiyoboro yo gusudira ikunze koherezwa hanze igabanijwemo LSAW na SSAW. Waba uzi itandukaniro riri hagati ya LSAW Umuyoboro na SSAW Umuyoboro?
Umuyoboro wa LSAW (Umuyoboro wa Longitudinal Submerged Arc-Welding), nanone witwa umuyoboro wa SAWL. Ifata isahani yicyuma nkibikoresho fatizo, ikabumba na mashini ibumba, hanyuma ugakora impande zombi zashizwemo arc gusudira. Binyuze muriyi nzira umuyoboro wa LSAW uzabona ihindagurika ryiza, gukomera gusudira, uburinganire, plastike hamwe no gufunga bikomeye.
Umuyoboro wa LSAW umuyoboro uruta ERW, mubisanzwe kuva kuri santimetero 16 kugeza kuri 60, 406mm kugeza 1500mm. Imikorere myiza kumurwanya mwinshi, hamwe nubushyuhe bwo hasi.
Byakoreshejwe cyane mumiyoboro ya peteroli na gaze, bisabwa byumwihariko diameter nini numuyoboro wurukuta ufite imbaraga nyinshi nintera ndende. Hagati aho, mu iyubakwa ry'imiterere ikeneye imbaraga zikomeye, gutunganya amazi, inganda z’ubushyuhe, kubaka ikiraro, n'ibindi. Nkurikije ibisobanuro bya API, umuyoboro wa LSAW (umuyoboro wa SAWL cyangwa umuyoboro wa JCOE) wagenwe cyane cyane mu gutwara peteroli nini na gaze nini, mu bihe imiyoboro inyura mumujyi, inyanja, hamwe numujyi. Izi nicyiciro cya 1 nicyiciro cya 2.
Umuyoboro wa SSAW (Umuyoboro wa Spiral Submerged Arc-Welding Umuyoboro), nanone witwa umuyoboro wa HSAW (Helical SAW), umurongo wo gusudira umeze nka helix. Irimo ikoresha tekinoroji imwe yo gusudira ya Submerged Arc-Welding hamwe n'umuyoboro wa LSAW. Mu buryo butandukanye imiyoboro ya SSAW irazunguruka aho LSAW isudira igihe kirekire. Igikorwa cyo gukora ni ukuzunguruka umurongo wibyuma, kugirango icyerekezo kizunguruka kigire inguni nicyerekezo cyikigo cya pipe, gukora no gusudira, bityo ikidodo cyo gusudira kiri mumurongo uzunguruka.
Umuyoboro wa diameter ya SSAW uri hagati ya santimetero 20 na santimetero 100, mm 406 kugeza kuri mm 2540. Igice cy'inyungu ni uko dushobora kubona diameter zitandukanye z'imiyoboro ya SSAW ifite ubunini bungana bw'icyuma, hariho porogaramu nini ku bikoresho fatizo icyuma, hamwe no gusudira bigomba kwirinda imihangayiko yibanze, imikorere myiza yo kwihanganira imihangayiko.
Ikibi ni igipimo kibi cyumubiri, uburebure bwo gusudira burebure burenze uburebure bwumuyoboro, byoroshye gutera inenge zimeneka, umwobo wikirere, gushyiramo cinder, gusudira igice, imbaraga zo gusudira mukureshya.
Kubijyanye na sisitemu ya peteroli na gazi, ariko mubisobanuro bya peteroli, umuyoboro wa SSAW / HSAW washoboraga gukoreshwa gusa mubyiciro 3 nicyiciro cya 4. Imiterere yubwubatsi, gutwara amazi no gutunganya imyanda, inganda zumuriro, inyubako nibindi
