Dufite ubuhanga bwo gutanga ibisobanuro bitandukanye bya Round Hollow Structural Steel Pipe, niba hari ibyo ukeneye, nyamuneka twandikire, dutegereje gufatanya nawe!
Imiyoboro y'icyuma ya LSAW isudira ikorwa cyane cyane mugukora ibyapa mubyuma ukoresheje uburyo bwo kubumba JCOE, bigakurikirwa no gusudira ukoresheje impande zombi zuzuye amazi (DSAW) tekinoroji yo gusudira, ikarangizwa binyuze mubugenzuzi bwinshi no kuvura.
Nigute ushobora guhitamo inzira nziza yo gukora?Ni irihe tandukaniro n'ibyiza by'umuyoboro w'icyuma udafite kashe, LSAW, gusudira arc kurengerwa, hamwe no gusudira arc?Nubuhe bunini bwa buri gikorwa?Urashobora gukanda kumurongo ukurikira kugirango ubone.

Ibikoresho bya BS EN 10210 birimo imbaraga zumusaruro, imbaraga zingana, kuramba, ningaruka zingaruka.
Ibice bitoboye bigomba kugira ubuso bunoze bujyanye nuburyo bwo gukora bwakoreshejwe;ibibyimba, imyenge, cyangwa ibinure birebire biturutse kubikorwa byo gukora biremewe, mugihe umubyimba uri mubwihanganirana.
EN 10210 Ubuso bwumuyoboro wibyuma birakwiriye gushiramo imbaraga.
EN 10210 ntisaba gupima hydrostatike yumuvuduko wibyuma.
Ni ukubera ko ibicuruzwa bisanzwe EN 10210 bikoreshwa cyane cyane mubikorwa byubaka ntabwo ari sisitemu yo kuvoma igomba gukorerwa igitutu.
Niba hakenewe igeragezwa ryumuvuduko wa hydrostatike, ushobora kwifashisha ibipimo bya EN 10216 (ibyuma bitagira ibyuma) cyangwa EN 10217 (ibyuma bisudira).
Nta gisabwa giteganijwe mubisanzwe kugirango ukore NDT kumiyoboro yicyuma.
Niba NDT ikozwe kumiyoboro y'icyuma yasuditswe, ibisabwa bikurikira birashobora koherezwa.
Ibice byo gusudira amashanyarazi
Kubice byizengurutse igice cyicyuma ni ERW.
Urashobora guhitamo bumwe muburyo bukurikira bwo kugerageza.
a) EN 10246-3 kugeza kurwego rwa E4, usibye ko tekinike yo kuzunguruka / pancake coil tekinike itemewe;
b) EN 10246-5 kugeza kurwego rwo kwemerwa F5;
c) EN 10246-8 kugeza kurwego rwo kwemerera U5.
Amazi ya Arc Welded Ibice
Kubice byizengurutse igice cyicyuma ni LSAW na SSAW.
Ikirangantego cyo gusudira cyamazi ya arc yarengewe ibice bizageragezwa hashingiwe kuri EN 10246-9 kugeza kurwego rwa U4 cyangwa kuri radiografiya ukurikije EN 10246-10 hamwe nicyiciro cyiza cya R2.
Kubindi bisobanuro birambuye kubisabwa bijyanye no kwihanganira ibipimo,nyamuneka kanda hano kugirango ubone ibisobanuro byinshi.

Kuva yashingwa mu 2014,Botop Steelyabaye umuyobozi wambere utanga imiyoboro ya karubone mumajyaruguru yUbushinwa, izwiho serivisi nziza, ibicuruzwa byiza, nibisubizo byuzuye.
Isosiyete itanga imiyoboro inyuranye y’ibyuma bya karubone n’ibicuruzwa bifitanye isano na byo, birimo icyuma, ERW, LSAW, hamwe n’icyuma cya SSAW, ndetse n’umurongo wuzuye w’ibikoresho bya flanges na flanges.Ibicuruzwa byayo bidasanzwe birimo kandi amavuta yo mu rwego rwo hejuru hamwe na austenitis ibyuma bitagira umuyonga, bigenewe guhuza ibyifuzo byimishinga itandukanye.
