Imigangatho yoLawulo oluPhezulu lweMigudi yentsimbi

Ungqengqelo lwesamente udityaniswe ne-Epoxy Coades. Faka isicelo se-ZINC kwaye usebenzise i-asphalt antiikorrosion upeyinti. Ubungqingqwa be-chinc yokutshiza inyibiliki ayiyi kuba ngaphantsi kwe-130g / ㎡, kunye nomxholo we-zinc winc uya kuba ngama-99.95%.
1.1 Iimfuneko zobugcisa
1.2 imigangatho yokuphumeza
I-1.GGB / T13295-2013 I-Puipe yentsimbi yentsimbi, umbhobho kunye nezixhobo zePiidie yePipho kunye negesi;
I-2. I-Pipe Fettings Line idityaniswe nodaka lwesamente, i-spray i-asphanity ye-asphan, i-ISO4179 kunye ne-ISO8179 imigangatho ngokwahlukeneyo.
3. I-Epoxy Trainity yelali yelali yangaphakathi idibana ne-ISO 16132-2004
I-4. Umbhobho wokuzingca uhambelana ne-GB / T13295-2013, i-Ductile yentsimbi, izixhobo zombhobho kunye nezixhobo zeplanga kunye negesi
5. Iindlela zokuvavanywa, imithetho yokuhlola, ubungakanani, ubunzima kunye nokuphambuka okuvumelekileyo, ukupakisha, ukuthutha, ukugcinwa, iimfuno zobugcisa ziya kwenziwa ngokwe-GB / T13298 emiselweyo.
1.3 Iipropathi zoomatshini
Iityhubhu zenziwa yinkqubo yokuphosa i-centrifugal kwaye kufuneka zidityaniswe ngeepropathi zoomatshini ngolu hlobo lulandelayo:
Amandla e-thensle (MPA)
Isivuno (MPA)
ubunzima (i-HBW)
Mkhulu okanye ulingana no-420
Mkhulu okanye ulingana no-300
Ngaphantsi okanye ilingana no-230
1.4 Ubume, ubume, kunye nobunzima
1. Unxibelelwano luyamkela i-Toling-Tectory-increen ye-T
2. Ubude obufanelekileyo l =6000} kwi-MM, kunye neBanga loTyelo yi-K9.
I-3. Indawo yokuphela kombhobho wentsimbi yentsimbi kufuneka ibe yi-axis.
I-4. Ukucaciswa kombhobho kunye nokuphambuka okuvumelekileyo kuya kuthobela izibonelelo ze-GB / T13295-2013.
5. Ukwamkelwa kwesisindo: Ngokobalo lwesizwe olusemgangathweni, impazamo evumelekileyo yokunyamezelana komgangatho kwi-3%.
1.5 Iimfuneko eziMgangatho
1. Umbhobho wentsimbi yentsimbi uya kwenziwa ngentsimbi yentsimbi ye-ferritar matric. Kuya kubakho inani elithile legrafu ye-spherite kwi-tishu.
2. Uvavanyo lwe-hydrostatic, amandla e-thenrostatic kunye ne-elongwation baya kuthobela amalungiselelo e-GB / T13295 ukuya kwi-913 emiselweyo.
3. Ubunzima bomphezulu awuyi kuba ngaphezulu kwe-230 HBW.
4. Umphezulu wangaphakathi nangaphandle awuyi kuba neziphene ezithintela ukusetyenziswa.
5. Umbhobho wentsimbi bin udityaniswe nodaka lwesamente, inxenye yesamente efakwe kwi-Epoxy Traing, phambi kwe-chinc spray asping, ngaphandle kwe-rump, ngaphandle kwe-rump. Emva kokukhathazeka, umphezulu wangaphakathi nangaphandle kufuneka ugudile, ukungqengqeleka kuyinto efanayo, kwaye inamathela ngokunamathela, kwaye ingabi nakho ngenxa yemozulu ebandayo nenokubandayo. Ubunzima bokufakwa kombhobho wesamente bungaphantsi kwe-0.013, kunye noburharha bokufakelwa kwesamente Ubungqingqwa be-chinc yokutshiza inyibiliki ayiyi kuba ngaphantsi kwe-130g / ㎡, kunye nomxholo we-zinc winc uya kuba ngama-99.95%.
6. Tsala umphezulu wesokisi kunye ne-GB / T13295-2013.
I-7. Kwindawo nganye ye-ductile yombhobho kunye nezixhobo zombhobho, kwaye imali eshiyekileyo iya kubonelelwa nge-1% yenani elipheleleyo lexabiso lerabha, kwaye iKoteyishini iya kubandakanywa kwixabiso le-bid lilonke.
I-8. Umbhobho wenziwa nge-lining cemetion on kunye ne-epoxy conces, udonga lwangaphandle luhlanganiswe nge-asphalt, isamente ye-Iso7179, i-asphalt ye-ESPOLY, kunye ne-Epopy COADS,
