JIS G 3452ni igipimo cy’Abayapani gisobanura imiyoboro y’icyuma cya karuboni ikoreshwa mu gutwara umwuka, amazi, peteroli, gaze, umwuka, nibindi ku gitutu gito gikoreshwa. JIS G 3452 igizwe n’ubwoko bumwe gusa, SGP, bushobora gukorwa hakoreshejwe resistance welding (ERW) cyangwa butt welding.
JIS G 3452 Imiyoboro y'icyuma igomba gukorwa hakoreshejwe uburyo bukwiye bwo gukora imiyoboro n'uburyo bwo kurangiza.

Imiyoboro isanzwe igomba gutangwa uko yakozwe. Imiyoboro ikonje igomba gufungwa nyuma yo gukorwa.
Iyo umuyoboro wakozwe na ERW, imiyoboro iri imbere n'inyuma by'umuyoboro igomba gukurwaho kugira ngo haboneke umuyoboro mwiza ku nkengero z'umuyoboro.
Iyo bibuze bitewe n'umurambararo w'imiyoboro cyangwa ibikoresho, n'ibindi, ubushuhe buri imbere ntibushobora gukurwaho.
Gutegura: Mbere yo gukoresha galvanizing ishyushye, ubuso bw'umuyoboro w'icyuma bugomba gusukurwa neza hakoreshejwe umucanga, gusya, n'ibindi.
Ubunini: Ku bijyanye no gusiga zinc, hagomba gukoreshwa ingot ya zinc yaciwe mu cyiciro cya 1 cyavuzwe muri JIS H 2107 cyangwa zinc ifite nibura ubuziranenge bungana na yo.
Ibindi: Ibindi bisabwa rusange mu gukaranga ibyuma bihuye na JIS H 8641.
Ikizamini: Gupima ingano y'igitambaro cya galvanised hakurikijwe JIS H 0401 Ingingo ya 6.
Uretse ibintu byatanzwe, hari ibindi bintu bishobora kongerwamo uko bikenewe.

JIS G 3452 ifite imbogamizi nke ku miterere y’ibinyabutabire kuko JIS G 3452 ikoreshwa cyane cyane mu bikorwa rusange nko gutwara umwuka w’amazi, amazi, peteroli na gaze karemano. Imiterere y’ibinyabutabire mu bikoresho si cyo kintu cy’ingenzi cyane, ahubwo ni imiterere y’imiyoboro kugira ngo ihangane n’umuvuduko w’akazi.

Ku miyoboro ifite umurambararo wa 32A cyangwa munsi yayo, agaciro k’uburebure kari muri iyi mbonerahamwe ntigakurikizwa, nubwo ibisubizo byayo by’uburebure bigomba kwandikwa. Muri iki gihe, ibisabwa byo uburebure byemejwe hagati y’umuguzi n’uwakoze bishobora gukoreshwa.
Umutungo wo gusana
Ubuso: Ku miyoboro ifite umurambararo urenze 50A (2B).
Nta mivuniko ibaho iyo umuyoboro ugoswe kugeza kuri 2/3 by'umurambararo wo hanze w'umuyoboro.
Gukomera
Ingano: Ku miyoboro y'icyuma ifite umurambararo muto ≤ 50A (2B).
Fata icyitegererezo kugeza kuri dogere 90 ufite umurambararo w'imbere ukubye inshuro esheshatu umurambararo w'inyuma w'umuyoboro nta nkomyi zirimo.
Buri muyoboro w'icyuma ugomba kugira ikizamini cy'umuvuduko wa hydrostatic cyangwa ikizamini kitangiza.
Ikizamini cy'amazi
Umuvuduko: 2.5 MPa;
Igihe: Bika byibuze amasegonda 5;
Icyemezo: umuyoboro w'icyuma uri munsi y'igitutu kidasohoka.
Ikizamini kitangiza
Isuzuma rya ultrasound ryavuzwe muri JIS G 0582 rizakoreshwa. Igipimo gishobora kuba gikomeye kurusha Category UE.
Ikizamini cya eddy current cyavuzwe muri JIS G 0583 ni cyo kizakoreshwa. Igipimo gishobora kuba gikomeye kurusha Category EZ.
Ku miyoboro ifite umurambararo wa nominelle ≥ 350A (14B), banza ubare umurambararo upime umuzenguruko, muri icyo gihe ubushobozi bwo kwihanganira ibintu ni ± 0.5%.
Ubwoko bw'iherezo ry'umuyoboro wa DN≤300A/12B: impera ifite imigozi cyangwa irambuye.
Ubwoko bw'iherezo ry'umuyoboro wa DN≤350A/14B: iherezo rirambuye.
Iyo umuguzi akeneye impera igosoye, inguni y'umugozi ni 30-35°, ubugari bw'umugozi w'icyuma ni 2.4mm ntarengwa.
JIS G 3452 ifite ibihwanye nabyo muriASTM A53naGB/T 3091, kandi ibikoresho by'imiyoboro bivugwa muri aya mahame bishobora gufatwa nk'ibingana mu bijyanye n'imikorere n'ikoreshwa.
Kuva yashingwa mu 2014, Botop Steel yabaye 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.
Twandikire, itsinda ry’abanyamwuga ryiteguye kuguha serivisi nziza n’ibisubizo, ritegereje kugirana ubufatanye bwiza nawe, no gufungura igice gishya cy’intsinzi.
