Ibyerekeye flange isanzwe SANS 1123

Munsi ya SANS 1123, hariho ubwoko butandukanye bwo kunyerera kuri flanges, gusudira ijosi,lap gufatanya,impumyinaurudodo.

Ukurikije ibipimo byubunini, SANS 1123 itandukanye nibisanzwe Abanyamerika, Abayapani n'Uburayi. Mu mwanya wa Class, PN na K, SANS 1123 ifata icyerekezo cyihariye: Urugero, hamwe na flange yo gusudira ijosi 600/3, 1000/3, 1600/3, 250/3, 4000/3, hamwe na flange yo gusudira ni zitandukanye, 600/2, 1000/2, 1600/2, 250/2, 4000/2, Impumyi y'impumyi ni 600/8, 1000/8, 1600/8, 2500/8, 4000/8, flange ifite umugozi ni 600 / 4, 1000/4, 1600/4, 2500/4, 4000/4, flange irekuye irashobora guhindurwa ubunini.

SANS 1123 flange yegereye flange yu Burayi yaranzwe na PN, kandi igipimo cyayo cyumuvuduko uri hagati ya 250 kPa kugeza 4000 kPa, ihindurwa mukigereranyo cyumuvuduko cyaranzwe na PN, aricyo PN 2.5 kugeza PN 40, ariko ubushyuhe bwayo bukoreshwa ni - 10 ℃ kugeza 200 ℃, kandi ubushyuhe bukoreshwa ni buto. Nyuma yo kugenzura, byagaragaye ko, ugereranije na BS EN 1092-1 flange, munsi yubunini bumwe hamwe nicyiciro kijyanye nigitutu, nubwo bimwe mubinini binini byerekana izina rya SANS 1123 flange byoroshye, diameter ya flange hanze, umwobo wa bolt umuzenguruko wa diameter, kwihuta no gutondekanya urudodo, bigena niba flanges ebyiri zishobora gukosorwa nizifunga, mubusanzwe zingana nuburinganire bwa flange, Kubwibyo, flang ya SANS 1123 yujuje cyane cyane ibisabwa mubyiciro bitandukanye byibikoresho byumushinga muri uyu mushinga.

Kubera ko urwego rw'ikoranabuhanga rukora imiyoboro y'ibyuma byo muri Afurika y'Epfo rusanzwe inyuma y'ibihugu byateye imbere mu Burayi no muri Amerika, ibipimo bya tekiniki by'imiyoboro y'ibyuma byakozwe hakurikijwe ibipimo bya Afurika y'Epfo biri hasi kandi ubushobozi bwo gutwara umuvuduko ni buke, ibyuma byo muri Afurika y'Epfo Umuyoboro usanzwe wuyu mushinga ukoreshwa gusa mu miyoboro ya karubone ifite ubushyuhe buke n’umuvuduko muke, hamwe nu miyoboro ya karubone ifite umuvuduko wo gushushanya ＞ 2.5 MPa cyangwa ubushyuhe bwo gushushanya ＞ 100 ℃ kandi imiyoboro yose idafite ibyuma ikurikiza amahame y’Amerika. Ibigize imiti nimbaraga zerekana ibikoresho byumuyoboro wibyuma mubipimo byibyuma byo muri Afrika yepfo hamwe nuburinganire bwibyuma byabanyamerika bifite itandukaniro, kandi imiyoboro imwe yicyuma ifite diameter zitandukanye (reba Imbonerahamwe 1, nka DN65). Nubwo ikibazo cyitandukanyirizo ryibintu bigize ibikoresho byibanze byicyuma kumpande zombi za weld birashobora gukemurwa binyuze muguhitamo inkoni zo gusudira no kunoza uburyo bwo gusudira, hamwe nikibazo cyo gutandukanya diameter yimbere yinyuma ya umuyoboro wibyuma kumpande zombi za weld urashobora gukemurwa hifashishijwe gutunganywa gutunguranye, nta gushidikanya ko bizana ingorane zikomeye mukubaka imiyoboro kandi ntabwo bifasha ubwishingizi bwubwubatsi. Ihuza rya kashe rishobora kugerwaho hifashishijwe ubufatanye bwa flange, gasketi na fastener. Igipapuro gitandukanya flanges kumpande zombi, kandi icyuma ntigisaba ibikoresho bimwe bya flanges kumpande zombi. Kubwibyo, itandukaniro riri hagati yimiterere yibintu na diameter yo hanze yimiyoboro yicyuma kumpande zombi irashobora gukemuka. Nyuma ya byose, guhuza imiyoboro yicyuma nibipimo bitandukanye mubisanzwe bibera ahantu urwego rwibikoresho ruhinduka. Ihuriro nkiryo ntabwo ari ryinshi, kandi gukoresha flanges ntabwo bizongera ikiguzi kinini kumushinga.
