Imiyoboro ishongeshejwe mu buryo bw'umwuka ku murongo wa gaze karemano yo munsi y'ubutaka Ishusho yagaragaye

Ibisobanuro bigufi:

Tubagezaho ibicuruzwa byacu bishya - umuyoboro ukozwe mu buryo bwa spiral welded, ukaba ari igice cy'ingenzi cy'uburyo bwo kohereza imiyoboro ya gaze karemano munsi y'ubutaka.

Ibisobanuro birambuye ku gicuruzwa

Ibirango by'ibicuruzwa

Imiyoboro ishongeshejwe mu buryo bw'umwukani ingenzi mu nganda, cyane cyane mu kubaka imiyoboro itwara peteroli na gaze. Ibipimo byayo bigaragazwa mu bugari bw'inyuma n'ubugari bw'urukuta, bigaragaza uburyo ikora neza kandi ihuzwa n'ibikenewe mu miyoboro itandukanye.

Uburyo bwo gukora imiyoboro ikoze mu buryo bw’umwuka bukoresha ikoranabuhanga rigezweho ryo gusudira imiyoboro, rigatanga imiyoboro ifite impande imwe cyangwa ebyiri. Iyi miyoboro yo gusudira ituma imiyoboro iramba kandi ikaba yizewe cyane, ikabasha kwihanganira ubukana bw’imiyoboro.umurongo wa gaze karemano wo munsi y'ubutakakohereza amakuru.

Mu kigo cyacu cy’ubucuruzi, twemeza ko imiyoboro yacu ikoze mu buryo bw’umwuka igeragezwa neza kugira ngo harebwe ko ifite ubushobozi bwo gukora neza. Ni ngombwa ko imiyoboro ikoze mu buryo bw’umwuka ikurikiza amabwiriza agenga igeragezwa rya hydraulic, imbaraga zo gukurura no gukonja kw’imitsi.

Imiyoboro yacu ikoreshwa mu buryo bw’umwuka ikozwe mu buryo bw’uruziga igamije kurenza amahame ngenderwaho mu nganda no kuzuza ibisabwa bikomeye by’uburyo bwo kohereza gazi karemano munsi y’ubutaka. Yagenewe kwihanganira ibidukikije bitandukanye, bigatuma iramba kandi ikagira umutekano mu buryo ubwo aribwo bwose.

Gukoresha imiyoboro ikoze mu buryo bwo gutwara gazi karemano munsi y’ubutaka bitanga uburyo bwiza kandi bunoze bwo gutwara gazi karemano. Kuba gazi ikora mu buryo bunoze bituma ijyamo kandi bikagabanya ibyago byo kuva cyangwa kwangirika uko igihe kigenda gihita, bigaha ababikora n’abakoresha amahoro yo mu mutima.

Twiyemeje guha abakiriya bacu ibicuruzwa byiza cyane, kandi imiyoboro yacu ikoze mu buryo bw’umwuka ni igihamya cy’uko twiyemeje gukora neza mu nganda. Dushyira imbere kuramba, imikorere n’umutekano by’ibicuruzwa byacu, tukareba ko byujuje kandi birenga ibisabwa n’uburyo bwo kohereza gazi karemano munsi y’ubutaka.

Muri make, imiyoboro yacu ikoze mu buryo bwa "spiral welded" ni ingenzi cyane mu kubaka no kubungabunga uburyo bwo gutwara gazi karemano munsi y'ubutaka. Kubera ko yubatswe neza, iyubahirizwa ry'amahame y'inganda, kandi ishishikajwe no kugira ubuziranenge, imiyoboro yacu ikoze mu buryo bwa "spiral welded" ni nziza cyane ku mushinga uwo ari wo wose wo kohereza gazi karemano. Dufatanye natwe gutanga imiyoboro ikoze mu buryo bwa "spiral welded" nziza cyane ku byo ukeneye mu kohereza gazi karemano munsi y'ubutaka.

Ibanjirije iyi: Umuyoboro w'icyuma gikozwe mu buryo bw'umwuka ukoreshwa mu miyoboro y'amazi yo munsi y'ubutaka

Ibikurikira: Ibyiza by'imiyoboro y'icyuma ya A252 Grade 3 ikoreshwa mu kubaka imiyoboro y'amazi mabi n'amavuta

Andika ubutumwa bwawe hano hanyuma ubwoherereze
