PE Linear epurasitiki pombi
Kuita: Kushanda tembiricha: -25 dhigirii ~ + 75 dhigirii (yakanyanya kushanda tembiricha ye polyethylene yakagadziridzwa: 105 dhigirii)
Kumanikidza kwepakati pekushanda: kudzvanywa kwakanaka ndeye 2.5MPa uye kudzvanywa kwakashata kuri 75 KPa
Corrosion resistance: nonoxidation acid (yakadai sehydrochloric acid, hydrochloric acid, dilute sulfuric acid, hydrofluoric acid), dilute nitric acid, alkali uye munyu mhinduro, asi isingadziviriri pakuora kweconcentrated nitric acid, concentrated sulfuric acid uye mamwe maoxidants akasimba. Good corrosion resistance kune organic solvents uye pane yakajairika tembiricha.
Yakajairika application: yakakodzera kune yakajairika corrosive liquid yepakati yekufambisa, yakanyanya kukodzera kutakurwa kwemvura yemumba uye kunwa mvura inotonhora uye inotonhora, kutapurirana kwemvura, hakukanganise kunaka kwemvura, zvinoenderana nezvinodiwa nehutsanana hwechikafu, kukwirira kupfeka kuramba yakakwirira density polyethylene pombi inogona kushandiswa zvakanyanya kutakura yakasimba mvura slurry semarasha, ore. Inoshandiswa zvakanyanya muzvigadzirwa zve petrochemical yemagetsi mvura mvura kuchengetedza kwezvakatipoteredza uye mamwe maindasitiri.
⑴ Kubatana kwakavimbika: iyo polyethylene pombi system yakabatana nemagetsi ekunyungudika kwemagetsi, uye kusimba kwejoinhi kwakakwira kupfuura iyo yemuviri wepombi.
⑵ Yakanaka yakaderera-kupikiswa kwematembiricha: kudzikira-tembiricha yekumisikidza yepolyethylene yakadzikira, inogona kushandiswa zvisina njodzi mutembiricha ye-60-60℃. Mukuvaka kwechando, nekuda kwemaitiro akanaka ekupikisa kwezvinhu, pombi brittle cracking haizoitiki.
⑶ Yakanaka kushushikana kwekupwanya kuramba: HDPE ine yakaderera gap senitivity, yakakwira shear simba uye yakanakisa kukwenya kuramba, kwezvakatipoteredza kusagadzikana kupaza kuramba zvakare kwakanyanya.
⑷ Yakanaka kemikari corrosion kuramba: iyo pombi yeHDPE inogona kushingirira mukuora kweakawanda makemikari media, uye makemikari aripo muvhu haazokonzeri kuparara kwepombi. Polyethylene insulator yemagetsi, isingaori, ngura kana electrochemical corrosion; haina kukurudzira kukura kwealgae, mabhakitiriya kana fungi.
⑸ Kuramba kuchembera, hupenyu hurefu hwesevhisi: pombi yepolyethylene ine 2-2.5% yekugovera yunifomu yekabhoni nhema inogona kuchengetwa mumhepo yekunze kana kushandiswa kwemakore makumi mashanu, pasina kukuvara nekuda kwemwaranzi yeultraviolet.
⑹ Kuramba kwakanaka kwekupfeka: muyedzo wekuenzanisa kupfeka kwepimbi yeHDPE pombi uye pombi yesimbi inoratidza kuti kusakara kwepombi yeHDPE kakapetwa kane kwepombi yesimbi. Mumunda wekutakura madhaka, mapaipi eHDPE ane kuramba achipfeka zvichienzaniswa nemapombi esimbi, zvinoreva kuti mapaipi eHDPE ane hupenyu hurefu hwebasa uye hupfumi huri nani.
⑺ Kunaka kuchinjika: kuchinjika kwepombi yeHDPE kunoita kuti zvive nyore kukotama, mainjiniya anogona kushandura mafambiro epombi akatenderedza zvipingamupinyi, muzviitiko zvakawanda, kuchinjika kwepombi kunogona kuderedza kuwanda kwepombi fittings uye kuderedza mari yekuisa.
⑻ Diki kuyerera kuramba: HDPE pombi ine yakatsetseka yemukati nzvimbo, uye yayo Manning coefficient i0.009. Kuita kwakatsetseka uye kusiri{1}}kunamira maitiro kunovimbisa kuti pombi yeHDPE ine kufambisa kwepamusoro kupfuura mapaipi echinyakare, asi zvakare inoderedza kupera simba uye kushandiswa kwesimba rekufambisa mvura.
⑼ Kubata kuri nyore: HDPE pombi yakareruka kupfuura kongiri pombi, galvanized pombi uye simbi pombi, iri nyore kutakura uye kuisa, yakaderera manpower uye zvinodiwa zvemidziyo, zvinoreva kuti kuisirwa mutengo weprojekiti kuderedzwa zvakanyanya.
⑽ Yakasiyana-siyana nzira itsva dzekuvaka: HDPE pombi ine akasiyana tekinoroji ekuvaka, pamusoro pekushandisa nzira yechinyakare yekuchera matongo, inogona zvakare kushandisa akasiyana siyana tekinoroji isina trenchless senge pombi jacking, kudhirowa kwakananga, lining, crack chubhu kuvaka, izvi kune vamwe hazvibvumidze kuchera, ndiyo yega sarudzo, saka HDPE pombi yekushandisa zvakanyanya.
1, kupfava: nekuti PE-RT yakapfava. Naizvozvo, hapana maturusi akakosha anodiwa panguva yekuvaka, saka mutengo wekuvaka wakaderera. 2, thermal conductivity: pombi inoshandiswa pakudziisa pasi inoda kuve nemafuta akanaka ekupisa. PE-RT ine yakanaka thermal conductivity, uye kupisa kwayo kunopeta zvakapetwa kaviri kwePP-R nePP-B mapaipi. Yakakwana pakudziisa pasi.3. Kupisa tembiricha yepamusoro: PE-RT inokwanisa kumira tembiricha yepamusoro kusvika pa90 degrees , ukuwo PEX ichikwanisa kusvika 65 degrees .4, yakaderera-kupindwa nekupisa uye kusapindirana nemamiriro ekunze: PE- -RT yakaderera-kushanda kwe tembiricha yakanaka. Mukuvaka kwechando, pombi haisi nyore kukanganiswa uye kuputsika, izvo zvinowedzera kushanduka kwegadziriro yekuvaka.5, kuchengetedza kwezvakatipoteredza: PE-RT uye PP-R inogona kushandiswa zvakare, pasina kusvibisa zvakatipoteredza. Uye PEX haigone kushandiswazve
