Pombi yemvura yesimbi yeAWWA C213ipurasitiki yeFBE inoshandiswa mukati nekunze kwepombi yesimbi kuti ishandiswe mumapombi esimbi epasi pevhu kana pasi pemvura.
Kuputira uku kunopa dziviriro kubva mukuora uye kunoita kuti hurongwa hwemapaipi hushande kwenguva yakareba munzvimbo dziri pasi pevhu kana pasi pemvura.
Dhayamita yekunze yepombi ≥ 660mm [24in]. Epoxy resin lining ine mukana wekupinda mupombi kuti iongororwe uye igadziriswe.
Dhayamita dzemapaipi esimbi <660mm [24in] dzinogonawo kukodzera, chero bedzi paine nzira yakakodzera yekutarisa kuvimbika kwependi yemukati.
Fusion Bonded Epoxy (FBE)ipurasitiki ye epoxy ine upfu hwakaoma inoiswa muchimiro chimwe chete, iyo, kana yashandiswa nekupisa, inogadzira maitiro emakemikari pamusoro pepombi yesimbi uku ichichengetedza hunhu hwayo.
Upfu hwe epoxy hunofanira kunge huine chinhu chimwe chete chinosanganisa fusion chinosanganisira epoxy resin, curing agent, catalyst, filler, colorant, flow control agent, uye UV inhibitor.
Zvinhu zvinofanira kutevedzera zvinodiwa neMutemo weMvura Inonwiwa Yakachengeteka.
Kana zvichidikanwa kuti NSF itevedzere zvinodiwa, zvinhu zvinosangana nemvura inonwiwa zvinofanira kusimbiswa zvinoenderana neNSF/ANSI/CAN Standard 61.
Kazhinji, tembiricha yepamusoro yekushandisa pakuputira inenge iri65°C (150°F)Uyezve, hupenyu hwebasa rejira rinoderedzwa nekuchengetedza tembiricha yakakwirira kwenguva yakareba.
Kana ikaiswa pazvinhu zvakatogadzirwa kare nekupfapfaidza nemagetsi, kupfapfaidza nemhepo kana nemhepo uye yozopora, upfu hwe epoxy hunogadzira chifukidziro chakafanana chekudzivirira.
Mabasa chaiwo ndeaya anotevera:
Kuongorora Mapaipi uye Kurapwa Kusati kwaitwa
Pamusoro pacho panofanira kunge pasina zvikanganiso zvinokanganisa chigadzirwa chekupedzisira, zvakaita semaburrs, magouges, uye ma weld spatters, izvo zvinogona kubviswa ne sandbage.
uye pamusoro pazvo panofanira kunge pasina ivhu, pendi yemugayo, wakisi, tara yemarasha, asphalt, mafuta, girizi, chlorides, uye chero chimwe chinhu chekunze kana tsvina inobvira inogona kubatidza pakupisa kwe epoxy yakasungirirwa. Bvisa mavanga anooneka emafuta negirizi nekupukuta nechinwiwa chisingasiyi masara.
Kugadzirira Pamusoro
Shandisa jecha rakaoma kuti uchenese ngura pamusoro pemapaipi esimbi.
Zvinodiwa Pakuputira: Kana tembiricha yepombi yesimbi iri 3°C (5℉) pamusoro petembiricha yedova.
Kuchena Kwepamusoro: Pamusoro pepombi yesimbi yakabviswa paganda inofanira kuenderana neSSPC-SP10/NACE Nhamba 2.
Kuomarara kwenzvimbo: Kudzika kwetsanga dzesimbi dziri pakati pe51-102 μm (2.0-4.0 mil) zvakayerwa zvichienderana neASTM D4417. Izvi zvinogona kuyerwa nechinhu chinoisa simbi kana mita yesimbi inoisa simbi.
Kuomarara kwepamusoro kwakadzika zvakanyanya kana kushoma zvakanyanya kuchakanganisa mashandiro eFBE coating yekupedzisira.
Cherechedza: Ndapota cherechedzai nguva iri pakati pekupedzwa kwekubvisa ganda uye maitiro ekuputira kuti musaita ngura.
Kuchenesa Mhepo
Mhepo yakamanikidzwa isina kusvibiswa inofanira kushandiswa kuputitsa guruva, mavhu, kana zvimwe zvinhu zvinobva pasi pepombi nenzira isingakanganisi nzvimbo yakacheneswa, imwe pombi yakacheneswa, kana pombi inofanira kuputirwa kana kuputirwa.
Kudziisa Mapaipi
Pisa pombi yesimbi uchishandisa chinhu chinopisa chisingafaniri kusvibisa pamusoro pepombi, asi chisingafaniri kudarika 274°C (525°F).
Kupisa kwakanyanya kunogona kuchinja hunhu hwesimbi uye kusimba kwayo.
Kupisa pamusoro pepombi yesimbi kunogona kuyerwa uchishandisa chinyoreso chethermometer kana thermometer yemaziso yakaganhurirwa.
Kana ruvara rwebhuruu rukaitika, pombi inofanira kutonhodzwa kusvika patembiricha yekunze yobva yaputirwazve.
Maitiro Ekuputira
Upfu hweFBE hunoiswa zvakaenzana pamusoro pepombi yesimbi inodziya nekunyungudutsa mubhedha, kupfapfaidza nemagetsi, kana kupfapfaidza nemhepo.
Migero, yakachekwa, kana pamusoro pemidzi hazvifanirwe kuputirwa neFBE.
Kana majoini ane rabha kana majoini emakanika ashandiswa, epoxy inofanira kusvika kumagumo epombi kunze kwekunge zvataurwa neimwe nzira nemutengi.
Kutonhodza
Kutonhodza kunogona kuitwa nemhepo kana mvura.
PQT: Tenga AWWA C213 Water Transmission Steel Pipe muzvikamu zvidiki zvekuedza usati watenga zvakawanda. Kuongororwa kwekutanga kana kuyedzwa kunoitwa kuti uve nechokwadi chekuti chigadzirwa kana sisitimu inosangana nemhando chaiyo uye zvinodiwa pakushanda.
Izvi zvinosanganisira kuongororwa kwemurabhoritari, ongororo yekushanda, uye mamwe maitiro.
Kuonekwa
Epoxy inofanira kunge yakapfava.
Epoxy haifanirwe kunge isina maronda, mitswe, mabhuru, delamination, kana zvimwe zvinoonekwa zvisina kunaka.
Zvisina kunaka zvekushongedza, zvakaita sekudonha kweganda, kupwanyika kweganda, kukwesha, kuvharwa kweganda, kupfapfaidzwa pamusoro, uye/kana ganda reorenji, hazvifanirwe kunzi ndizvo zvinokonzera kurambwa kana kugadziriswa.
Kuongororwa kwemagetsi kuti kuenderere mberi (kuyedzwa kwezororo remagetsi mashoma)
Kuramba kwakaita chifukidziro kunofanira kuongororwa zvichienderana neNACE SPO490.
Zvemachiraine ukobvu hwe20 mils (508 um) kana pasi, chinhu chinoongorora zororo chine voltage shoma chakaiswa pa75 V chinofanira kushandiswa zvichienderana neNACE SPO188.
Kana huwandu hwemazororo hukadarika huwandu huri pasi pechifukidziro huchafanirwa kubviswa uye kugadzirwa patsva.
Dhayamita yekunze (OD) <14in (360 mm), 1 zororo/mita (3 ft).
Dhayamita yekunze (OD) ≥ 14in (360 mm), 1 holiday/25 ft² (2.3 mm²).
Tora mazororo akaongororwa, uzvigadzirise, uye uzviedzezve.
Kunamatira
Kunamatira kwe epoxy yakacheneswa pamusoro pepombi kunogona kuitwa nekusundira banga rakapinza nepa epoxy pamusoro pepombi uye kushandisa kufamba kwegedhi mukuyedza kubvisa epoxy pamusoro pepombi.
Epoxy inofanira kunamirwa zvizere papombi iri papombi kuti irambe yakasimba pakuita kwekurima uye isapararire nemarara uye isasangana nechinhu chinopwanyika.chiyero chekunamatira che1-3.
Ukobvu
Ukobvu hwefirimu rekupenda rakagadziriswa harifanirwe kunge riri pasi pe305um (12mil), kusanganisira misono yeweld.
Mushanduro yekare yeAWWA C213, paive nemuganho we406 um (16 mils) ukobvu hwepamusoro hwekufukidza, hwakabviswa mushanduro yazvino nekuda kwekuomerwa kwekuzadzisa zvinodiwa izvi panguva yekugadzira chaiyo.
Miedzo Yokuwedzera
Miedzo yekuwedzera inogona kutsanangurwa kuti ione mashandiro e epoxy.
1. Kuboorwa kwechikamu chakasiyana.
2. Kupinda kwemukati.
3. Kuongorora kupisa (DSC).
4. Kuoma zvachose (kukombama).
5. Kunyikwa mumvura.
6. Mhedzisiro.
7. Kuedzwa kwekubuda kweCathodic.
Inofanira kunyorwa zvakajeka nezita remugadziri, rudzi rwezvinhu, nhamba yebatch kana lot, zuva rekugadzirwa, uye mamiriro ekuchengetera.
Zvikurukuru zvemapaipi emvura
Mapendi ekunze anowanzo shandiswa kudzivirira mapaipi kubva mukuora kwezvakatipoteredza, nepo mapendi emukati achishandiswa kudzivirira kusvibiswa nemvura, kuderedza kukweshana, uye kuwedzera hupenyu hwemapaipi. Mapendi aya anobatsira kuona kuvimbika uye kugara kwenguva refu kwemapaipi, kutevedzera mitemo yehutsanana, uye kuderedza kudiwa kwekugadzirisa.
