Omutindo gw'okulondoola omutindo ogusembyeyo ku payipu z'ekyuma ezikola ductile .

Sseminti omubisi guteekebwako okusiiga epoxy. Siiga eddagala erifuuyira zinki era osiige langi ya kolaasi anticorrosion. Obugumu bw’ekyuma ekifuuyira zinki tebulina kuba wansi wa 130g / ゴ
1.1 Ebyetaago eby’ekikugu .
1.2 Emitendera gy’okussa mu nkola .
1.GB / T13295-2013 Payipu ya ductile ekyuma, payipu n’ebikozesebwa mu payipu y’amazzi ne ggaasi;
.
3. Epoxy sealing layer y’ekyalo eky’omunda etuukana n’omutindo gwa ISO 16132-2004 .
(
.
1.3 Ebintu eby’okukanika .
Tubu zino zikolebwa mu nkola ya centrifugal casting era zirina okufumbirwa n’ebyuma nga bwe ziti:
Amaanyi g’okusika (MPA) .
Amaanyi g’amakungula (MPA) .
Obukakanyavu (HBW) .
Ekisinga oba ekyenkana 420 .
Ekisinga oba ekyenkana 300 .
ebitono okusinga oba byenkana 230 .
1.4 Ebipimo, enkula, n’obuzito .
1. Enkolagana yeettanira okusereba-mu t-ekika ky’enkolagana n’omuntu yennyini-egya anchor, era obunene butuukiriza ebisaanyizo ebiri mu mutindo gwa GB / T13295-2013.
2. Obuwanvu obukola l=6000mm, ne pressure grade biba K9.
3. Enkomerero ya payipu y’ekyuma ekisuuliddwa erina okuba nga yeesimbye ku kisiki.
4. Ebiragiro bya payipu n’okukyama okukkirizibwa birina okugoberera ebiragiro bya GB / T13295-2013.
5. Okukkiriza obuzito: Okusinziira ku kubala omutindo gw’eggwanga, ensobi ekkirizibwa ey’okugumiikiriza kw’omutindo eri omutindo eri ± 3%.
1.5 Ebisaanyizo by’omutindo .
. Mu bitundu by’omubiri (speerical graphite) mulina okubaamu omuwendo ogw’enkulungo.
2. Okugezesa amazzi, amaanyi g’okusika n’okuwanvuwa birina okugoberera ebiragiro ebiri mu mutindo gwa GB / T13295-2013.
3. Obukakanyavu obw’okungulu tebulina kuba bunene okusinga 230 HBW.
4. Ebitundu eby’omunda n’eby’ebweru tebirina kuba na bulema obulemesa enkozesa.
. Oluvannyuma lw’okusiiga, oludda olw’omunda n’olw’ebweru lulina okuba nga luweweevu, ekizigo kiba kya kimu, kinywerera ku kwekwata, so si kya bulijjo olw’embeera y’obudde ennyogovu n’ennyogoga. Obukakanyavu bwa payipu ya seminti ey’okusiiga amayinja buli wansi wa 0.013, ate obukaluba bwa seminti obuyitibwa mortar lining nga bulimu epoxy sealing layer buba wansi wa 0.008. Obugumu bw’ekyuma ekifuuyira zinki tebulina kuba wansi wa 130g / ゴ
6. Fuuyira kungulu kwa socket ne GB / T13295-2013.
7. Ku buli kifo ekifuluma mu ductile iron payipu ne payipu ebikozesebwa, era omuwendo gwa sipeeya gulina okuweebwa ku 1% ku muwendo gwonna ogw’empeta za kapiira, era quotation ejja kuba mu muwendo gwonna ogw’okutunda.
