GOST 33259 ndi muyezo wopangidwa ndi Russian National Standard Technical Committee (Russian National Standard) pofotokozera ma flanges achitsulo.Muyezo uwu umagwiritsidwa ntchito kwambiri ku Russia ndi mayiko ena omwe kale anali Soviet Union ndi madera ena.
Mtundu wa Flange:
Muyezo umaphatikizapo mitundu yosiyanasiyana yazitsulo zachitsulo, mongaWelding Neck Flange, Blind Flange, Slip-On Flange, Mtundu wa Flange, ndi zina.Mtundu uliwonse wa flange uli ndi njira zolumikizirana zosiyanasiyana komanso zochitika zomwe zimagwira ntchito.
Kukula kwake:
GOST 33259 imatchula mitundu yosiyanasiyana ya ma diameter a flange mu makulidwe osiyanasiyana kuyambira 15mm mpaka 2000mm.Izi zikutanthauza kuti muyezo ndi woyenera kugwirizana ndi ntchito zosiyanasiyana mapaipi diameters.
Mulingo Wopanikizika:
Muyezo wa GOST 33259 umakwirira ma flanges achitsulo a magulu osiyanasiyana okakamiza, nthawi zambiri kuphatikiza PN6, PN10, PN16, PN25, PN40 ndi zina zotero.Mulingo uliwonse wokakamiza umagwirizana ndi kukakamiza kosiyanasiyana ndi zofunikira za kutentha kuti zikwaniritse zosowa zamainjiniya osiyanasiyana.
Kuchuluka kwa ntchito:
Muyezo wa GOST 33259 umagwira ntchito pazitsulo zachitsulo zolumikiza mapaipi ndi zida zapaipi.Ma flanges awa amagwiritsidwa ntchito makamaka pamakina osiyanasiyana otumizira madzi ndi gasi m'mafakitale ndi zomangamanga.
Zofunikira:
Muyezowu umatchula zofunikira pazitsulo zazitsulo mwatsatanetsatane, kuphatikizapo mtundu wachitsulo chomwe chimagwiritsidwa ntchito, mankhwala, makina, ndi zofunikira zothandizira kutentha.Zofunikira izi zimapangidwira kuti zitsimikizire mtundu ndi kudalirika kwa ma flanges.
Muyezo wa GOST 33259, monga muyeso wamakampani m'chigawo cha Russia, ndiwofunikira kwambiri paukadaulo wamapaipi ndi ntchito zina zofananira mderali.Komabe, ndi chikhalidwe cha kudalirana kwa mayiko ndi kugwiritsa ntchito miyezo ya mayiko, mfundo zina zapadziko lonse (monga ANSI/ASME, ISO, EN, etc.) zimagwiritsidwa ntchito kwambiri padziko lonse lapansi.Pankhani ya mgwirizano wapadziko lonse kapena ntchito zapadziko lonse lapansi, njira zowonjezera zingafunikire kuganiziridwa kuti zitsimikizire kuti zofunikira zosiyanasiyana zachigawo ndi dziko zikukwaniritsidwa.
GOST 33259, monga chitsulo flange muyezo wopangidwa ndi Russian State Technical Committee for Standardization, ali ndi ubwino ndi kuipa.
Ubwino:
1. Kugwiritsidwa ntchito kwachigawo: GOST 33259 ndi muyezo wadziko lonse m'chigawo cha Russia, choncho chimakhala chovomerezeka komanso chovomerezeka m'derali.Muyezo wa GOST 33259 umagwiritsidwa ntchito kwambiri pantchito zauinjiniya ku Russia komanso m'maiko ena akale a Soviet ndi madera ena, kuthandiza kuwonetsetsa kuti pali kukhazikika komanso kusasinthika.
2. Thandizo la msika wapakhomo: Ku Russia, muyezo wa GOST 33259 umathandizidwa ndikuyendetsedwa ndi boma.Zogulitsa zomwe zimakwaniritsa mulingo uwu nthawi zambiri zimatha kukwaniritsa malamulo ndi zofunikira, zomwe zimapangitsa kupanga ndi kugula kwanuko kukhala kosavuta.
3. Yang'anani pa zosowa za m'deralo: Muyezo wa GOST 33259 umapangidwa molingana ndi zosowa zenizeni ndi ntchito zaumisiri m'chigawo cha Russia, choncho zimakhala bwino kuti zigwirizane ndi zofunikira zamakono ndi chilengedwe.
Zoyipa:
1. Zochepa za malo: GOST 33259 ndi chikhalidwe cha dziko la Russia, choncho kugwiritsidwa ntchito kwake padziko lonse kuli kochepa.Pankhani ya mgwirizano wapadziko lonse lapansi kapena ma projekiti apadziko lonse lapansi, pangafunike kuganiziranso mfundo zina zovomerezeka padziko lonse lapansi, monga ANSI/ASME, ISO, EN, ndi zina.
2. Kusintha kuchedwa: Popeza kuti kapangidwe kachitidwe kachitidwe kachitidwe kachitidwe kakhoza kukhala kochedwa, muyezo wa GOST 33259 ukhoza kutsalira kumbuyo kwa miyezo yapadziko lonse malinga ndi zofunikira zaukadaulo ndi uinjiniya.Zida zina zatsopano, matekinoloje, ndi machitidwe abwino mwina sizinaphatikizidwe munthawi yake.
3. Kuchepetsa kusankhidwa: GOST 33259 muyezo ukhoza kukhala wochepa malinga ndi mtundu wa flange, zofunikira zakuthupi ndi kukula kwake, ndipo sangathe kukwaniritsa mapulojekiti apadera apadera kapena zofunikira zenizeni.
Pazonse, muyezo wa GOST 33259 uli ndi ntchito yofunika kwambiri m'chigawo cha Russia ndipo umathandizira kulimbikitsa uinjiniya wa mapaipi pamagawo amadzi am'deralo, gasi, mafakitale ndi zomangamanga.Komabe, mumgwirizano wapadziko lonse lapansi kapena ntchito zapadziko lonse lapansi, malire a muyezowu akuyenera kuyesedwa, ndipo zinthu zomwe zimakwaniritsa miyezo yapadziko lonse lapansi zitha kusankhidwa kuti zikwaniritse zosowa zaumisiri ndi zofunikira.
