Umuyoboro w'icyuma cya karuboni wasutswe mu buryo bw'umwuka X60 SSAW Line Pipe Ishusho yagaragaye

Ibisobanuro bigufi:

Murakaza neza mu isi y'imiyoboro y'icyuma cya karuboni ikoze mu buryo bw'umwuka, udushya twinshi duhindura isi yagusudira imiyoboro y'icyumaIki gicuruzwa cyakozwe neza cyane kugira ngo kibe gikomeye, kiramba kandi gikoreshwe mu buryo butandukanye. Twishimiye kubagezaho ubwoko bwacu bw'imiyoboro ya karuboni ikoze mu buryo bw'uruziga, ikorwa neza binyuze mu kuzingira icyuma cy'imiterere ya karuboni nke mu duce tw'imiyoboro ku nguni runaka, hanyuma tugasudira imiyoboro y'imiyoboro.

Ibyacuimiyoboro y'icyuma cya karuboni ikoze mu buryo bw'uruzigabyagenewe by'umwihariko guhaza ibyifuzo byiyongera by'imiyoboro minini y'icyuma. Dukoresheje imirongo mito y'icyuma no gukoresha ikoranabuhanga rigezweho ryo gusudira, twabashije gukora ibicuruzwa byiza biruta ibyo twahanganye mu bijyanye n'ubwiza n'imikorere. Ibikoresho by'ingenzi bikoreshwa mu gukora birimo Q195, Q235A, Q235B, Q345, GR.B,X42,X52,X60,X70 n'ibindi.

Kimwe mu byiza by'ingenzi by'umuyoboro wacu w'icyuma gikozwe mu buryo bwa spiral welded steel ni uko uramba cyane. Iyi miyoboro irashobora kwihanganira imimerere mibi cyane, bigatuma iba nziza cyane mu nganda zitandukanye no mu bikorwa bitandukanye. Yaba ikoreshwa mu miyoboro y'amazi yo mu ngo, mu nganda cyangwa mu nyubako, imiyoboro yacu y'icyuma gikozwe mu buryo bwa spiral welded steel yagenewe kurenza ibyo witeze.

Uretse gukomera no kuramba, umuyoboro wacu w'icyuma cya karuboni ukozwe mu buryo bwa spiral welded ukoreshwa mu buryo butandukanye cyane. Imiterere yawo yihariye ituma byoroha kuwushyiraho no kuwuhuza n'imiyoboro itandukanye n'imiyoboro y'amazi. Kuva ku mishinga mito yo guturamo kugeza ku nganda nini, imiyoboro yacu itanga ibisubizo byiza kandi byizewe ku byo ukeneye byose mu bijyanye n'amazi.

Byongeye kandi, twishimira ubwiza n'ubudahemuka bw'imiyoboro yacu ya karuboni ikoze mu byuma bizunguruka. Buri muyoboro ukorerwa isuzuma rikomeye no kugenzura ubuziranenge kugira ngo ugenzure ibipimo byo hejuru. Ubwitange bwacu ku bwiza bugaragarira mu kunyurwa kw'abakiriya bacu, bishingikiriza ku bicuruzwa byacu kugira ngo bihuze n'ibyo bakeneye bitandukanye.

Twishimiye kubagezahoUmuyoboro wa X60 SSAWnk'igice cy'umuyoboro wacu w'ibicuruzwa. Ufite ubushobozi bwo kurwanya ingese no gukomera kurushaho, uyu muyoboro wagenewe by'umwihariko gutwara ibintu bitandukanye birimo peteroli na gaze karemano. Umuyoboro wa X60 SSAW ni igihamya cy'imbaraga dukomeje gushyira mu bikorwa ibisubizo bishya kugira ngo duhuze n'impinduka mu nganda.

Muri make, umuyoboro wacu w'icyuma gikozwe muri karuboni uhujwe n'imiyoboro ni ikintu cyiza cyane gihuza imbaraga n'uburambe bw'icyuma gikozwe muri karuboni hamwe n'uburyo bworoshye bwo gusudira no gukora ibintu bitandukanye. Ubushobozi bwawo bwo gukora imiyoboro minini y'icyuma ukoresheje uduce duto tw'icyuma butuma utandukanye n'uburyo gakondo bwo gukora imiyoboro. Byaba ari imiyoboro y'amazi yo mu rugo cyangwa ikoreshwa mu nganda, umuyoboro wacu w'icyuma gikozwe muri karuboni uhujwe n'imiyoboro ni amahitamo yizewe ku byo ukeneye byose mu bijyanye n'amazi. Izere ko twiyemeje gukora ubuziranenge, udushya no kunyurwa n'abakiriya kandi ureke ibicuruzwa byacu bisobanure ubunararibonye bwawe mu by'amazi.

Ibanjirije iyi: Umuyoboro w'icyuma ushongeshejwe: Ubuyobozi bwuzuye bwo kwemeza ko imiyoboro ikora neza kandi yizewe

Ibikurikira: Umuyoboro wa X52 SSAW wo gukwirakwiza gazi

Andika ubutumwa bwawe hano hanyuma ubwoherereze
