BS EN 10210 S275J0Hni igice cy'icyuma gishyushye kandi gifite ubugari cyakozwe kugira ngoIkigo cy'Ishuri Rikuru ry'Ubumenyi bw'Ibanze EN 10210mu buryo butandukanye bw'impande, kare, uruziga, cyangwa igice cy'uruziga.
Ibikoresho bya S275J0H birangwa n'imbaraga nkeya zo gutanga umusaruro wa 275 MPa ku bugari butarenze mm 16; ingufu nkeya zo gutanga umusaruro ni nibura 27 J kuri 0℃.
S275J0H igizwe n'ubwoko bw'icyuma cya karuboni, inomero y'icyuma1.0149, ifite imiterere myiza y’inyubako n’uburyo bwo gutunganya, ikoreshwa cyane cyane mu nyubako, ariko kandi ikoreshwa mu bice bidatwara imizigo, ishobora gutuma inyubako igumana umutekano kandi iramba hashingiwe ku nyungu zihendutse.
Icyitonderwa: Ibisabwa byose muri BS EN 10210 bireba kandi EN 10210 bityo ntibisubirwamo hano.
Ibyiciro muri BS EN 10210 bigenwa hakurikijwe EN 10027-1 naho inomero z'icyuma zigenwa hakurikijwe EN 10027-2.

Twibanda ku gutanga ibipimo bitandukanye by'umuyoboro w'icyuma uzunguruka, niba hari icyo ukeneye, twandikire, twiteguye gukorana nawe!
Imiyoboro y'icyuma ikoreshwa muri LSAW ikorwa ahanini hakoreshejwe uburyo bwo gushushanya JCOE, hanyuma hagakurikiraho gusudira hakoreshejwe uburyo bwo gushushanya bufite impande ebyiri (2.5m).DSAW) ikoranabuhanga ryo gusudira, kandi rirangira binyuze mu igenzura n'uburyo butandukanye bwo kuvura.
Ni gute wahitamo inzira ikwiye yo gukora? Ni izihe tandukaniro n'ibyiza by'imiyoboro y'icyuma idakora, LSAW, gusudira arc icukurwa mu mazi, no gusudira arc icukurwa mu mazi? Kandi ingano ya buri gikorwa ni iyihe? Urashobora gukanda kuri iyi link ikurikira kugira ngo uyirebe.

Imiterere ya BS EN 10210 irimo imbaraga zo gukuraho, imbaraga zo gukurura, uburebure, n'ubushobozi bwo gukora ingaruka.
Ibice bifite ububobere bigomba kugira ubuso bworoshye bujyanye n'uburyo bwo gukora; utugumba, imyobo, cyangwa imiyoboro miremire ikomoka mu gikorwa cyo gukora biraremewe, mu gihe ubunini bushobora kwihanganira.
EN 10210 Imiyoboro y'icyuma ikwiriye gukoreshwa mu gushyushya ibyuma bishyushye.
EN 10210 ntisaba gupima umuvuduko wa hydrostatic ku miyoboro y'icyuma.
Ibi biterwa nuko ibikoresho bisanzwe bya EN 10210 ahanini bikoreshwa mu nyubako atari mu miyoboro igomba gushyirwamo igitutu.
Niba hakenewe isuzuma ry’umuvuduko wa hydrostatic, hashobora kwitabwaho amahame ya EN 10216 (imiyoboro y’icyuma idafite umushono) cyangwa EN 10217 (imiyoboro y’icyuma ivanze).
Nta tegeko risabwa mu buryo busanzwe kugira ngo umuntu akore NDT ku miyoboro y'icyuma ifite ibice bidafite aho biboshye.
Niba NDT ikorerwa ku miyoboro y'icyuma ishongeshejwe, ibisabwa bikurikira bishobora kwerekezwaho.
Ibice bya Electron Welded
Ku miyoboro y'icyuma ifite impande zizengurutse, ERW ni yo ikoreshwa.
Ushobora guhitamo bumwe mu buryo bukurikira bwo kugerageza.
a) EN 10246-3 kugeza ku rwego rwo kwemerwa E4, usibye ko tekiniki yo kuzunguruka y'umuyoboro/panikeke itemerewe kwemerwa;
b) EN 10246-5 kugeza ku rwego rwo kwemerwa F5;
c) EN 10246-8 kugeza ku rwego rwo kwemerwa U5.
Ibice bya Arc Welded byuzuyemo
Ku miyoboro y'icyuma ifite impande zizengurutse, harimo LSAW na SSAW.
Umugozi wo gusudira w'ibice bifite ububobere buvanze n'imirongo y'amazi ugomba kugeragezwa hakurikijwe EN 10246-9 kugeza ku rwego rwo kwemerwa rwa U4 cyangwa hakoreshejwe radiyo hakurikijwe EN 10246-10 hamwe n'icyiciro cy'ubuziranenge bw'ishusho R2.
Kugira ngo ubone amakuru arambuye ku bisabwa bijyanye n'ubushobozi bwo kwihanganira ibintu,kanda hano kugira ngo umenye byinshi.

Mu guhitamo EN 10210 S275J0H ihwanye, hagomba gukorwa igereranya rirambuye ry’imiterere y’ibinyabutabire n’imiterere ya mekanike kugira ngo harebwe ko ibikoresho byatoranijwe byujuje ibisabwa byihariye by’umushinga.
Kuva yashingwa mu 2014,Botop Steelyabaye ikigo gikomeye mu kugurisha imiyoboro y'icyuma cya karuboni mu majyaruguru y'Ubushinwa, kizwiho gutanga serivisi nziza, ibicuruzwa byiza, n'ibisubizo byuzuye.
Iyi kompanyi itanga imiyoboro itandukanye y’icyuma cya karuboni n’ibindi bifitanye isano, birimo imiyoboro y’icyuma idakora neza, ERW, LSAW, na SSAW, ndetse n’urutonde rwuzuye rw’imiyoboro n’ibice bifunganye. Ibicuruzwa byayo byihariye birimo kandi alloys nziza n’ibyuma bitarangirika bya austenitic, byakozwe kugira ngo bihuze n’ibikenewe mu mishinga itandukanye y’imiyoboro.
