JIS G 3452ni igipimo cy’Ubuyapani cyerekana umuyoboro wa karuboni wasuditswe kugirango utwarwe n’amazi, amazi, peteroli, gaze, umwuka, nibindi ku gipimo gito cyakazi.JIS G 3452 igizwe nicyiciro kimwe gusa, SGP, ishobora guhimbwa haba gusudira (ERW) cyangwa gusudira.
JIS G 3452 Imiyoboro yicyuma igomba guhimbwa hifashishijwe uburyo bukwiye bwo gukora imiyoboro nuburyo bwo kurangiza.

Imiyoboro igomba gutangwa nkuko byakozwe.Imiyoboro ikonje ikonje igomba gufatanwa nyuma yo gukora.
Niba umuyoboro wakozwe na ERW, gusudira kumbere no hanze yumuringa bigomba kuvanwaho kugirango ubone gusudira neza kuruhande rwumuyoboro.
Niba bigarukira kubera diameter cyangwa ibikoresho, nibindi, gusudira hejuru yimbere ntibishobora kuvaho.
Gutegura: Mbere yo gushyushya-gushya, hejuru yumuyoboro wibyuma ugomba guhanagurwa neza no kumusenyi, gutoragura, nibindi.
Umubyibuho ukabije: Kuri zinc-coating, zinc ingot ingot yo mucyiciro cya 1 ivugwa muri JIS H 2107 cyangwa zinc ifite byibura uburinganire buringaniye nibi bizakoreshwa.
Ibindi: Ibindi bisabwa rusange muri galvanizing bihuye na JIS H 8641.
Ikizamini: Gupima uburinganire bwikariso ukurikije JIS H 0401 Ingingo ya 6.
Usibye kubintu byatanzwe, ibindi bintu bivangavanze birashobora kongerwaho nkuko bisabwa.

JIS G 3452 ifite imipaka mike kubigize imiti kuko JIS G 3452 ikoreshwa cyane mubikorwa rusange nko gutwara amavuta, amazi, peteroli, na gaze gasanzwe.Ibigize imiti ntabwo aribintu byingenzi, ahubwo ni imiterere ya miyoboro yumuyoboro kugirango uhangane nigitutu cyakazi.

Ku miyoboro ya diameter nominal 32A cyangwa munsi yayo, indangagaciro zo kurambura muri iyi mbonerahamwe ntizikurikizwa, nubwo ibisubizo byikizamini cyo kuramba bizandikwa.Muri iki gihe, ibisabwa byo kuramba byumvikanyweho hagati yumuguzi nuwabikoze birashobora gukoreshwa.
Umutungo wuzuye
Igipimo: Kubituba bifite diameter nominal irenga 50A (2B).
Nta gucikamo iyo umuyoboro urambuye kugeza 2/3 bya diameter yo hanze yigituba.
Kwunama
Igipimo: Kubijyanye nicyuma gifite diameter nomero ≤ 50A (2B).
Hindura icyitegererezo kuri 90 ° hamwe na radiyo y'imbere inshuro esheshatu z'umurambararo wo hanze utarinze gutanga ibice.
Buri muyoboro wibyuma ugomba kugira hydrostatike yumuvuduko cyangwa ikizamini kidasenya.
Ikizamini cya Hydrostatike
Umuvuduko: 2.5 MPa;
Igihe: Fata byibuze amasegonda 5;
Urubanza: umuyoboro wibyuma munsi yigitutu nta kumeneka.
Ikizamini kidasenya
Ikizamini cya ultrasonic cyerekanwe muri JIS G 0582 kirakurikizwa.Urwego rwibizamini rushobora gukomera kurenza Urwego UE.
Ikizamini cya eddy cyerekanwe muri JIS G 0583 kirakurikizwa.Urwego rwibizamini rushobora gukomera kurenza Icyiciro EZ.
Ku miyoboro ifite diametre nominal ≥ 350A (14B), bara diameter kugirango upime umuzenguruko, mugihe kwihanganira ± 0.5%.
Ubwoko bwumuyoboro wa DN≤300A / 12B: urudodo cyangwa impera.
Ubwoko bwumuyoboro wa DN≤350A / 14B: impera iringaniye.
Niba umuguzi akeneye impera yacishijwe bugufi, inguni ya beveri ni 30-35 °, ubugari bwa bevel bwumuyoboro wicyuma: max 2.4mm.
JIS G 3452 ifite ibisa nayo muriASTM A53naGB / T 3091, n'ibikoresho by'imiyoboro ivugwa muribi bipimo birashobora gufatwa nkibingana muburyo bwo gukora no kubishyira mubikorwa.
Kuva yashingwa mu 2014, Botop Steel yabaye iyambere mu gutanga imiyoboro ya karubone mu majyaruguru y’Ubushinwa, izwiho serivisi nziza, ibicuruzwa byiza, ndetse n’ibisubizo 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.
Twandikire, itsinda ryumwuga ryiteguye kuguha serivisi nziza nibisubizo, dutegereje kugera kubufatanye bwiza nawe, hamwe no gufungura igice gishya cyitsinzi.
