Vharuvhu yebhora yepolyethylene (PE) yepasi pevhu chinhu chakakosha chekudzora chakagadzirirwa masisitimu emapombi epurasitiki yepasi pevhu (PE) mumagetsi emuguta nemvura. Vharuvhu iyi ine chimiro chepurasitiki chose (PE), ine zvinhu zvikuru iri polyethylene (PE100 kana PE80), uye chiyero chakajairwa (SDR) che11. Inodzivirira ngura zvakanaka, inodzivirira kukwegura, uye inoshanda sealant performance. Chinhu chikuru chekugadzira ndechekubatanidzwa kwevharuvhu huru nemavharuvhu maviri emhepo, zvichiita kuti pave nekuvhurwa nekuvharwa kwakachengeteka uye kuri nyore kwehurongwa hwepaipi, pamwe nekushanda kwepakati nepakati kwekutsiviwa. Vharuvhu yakavigwa zvakananga pasi pevhu uye inogona kushandiswa kubva pamusoro neruoko rwekudzivirira nekiyi yakatsaurirwa, zvichiita kuti kugadzirisa kuve nyore. Inyanzvi yakanaka yekuona kuti network dzemapaipi ePE pasi pevhu dzinoshanda zvakachengeteka uye zviri nyore.
Hunhu hweKushanda
Kuvhara Kwakanaka: Inoshandisa chimiro chechisimbiso chinoyangarara chinozvisimbisa chega kuti ive nechokwadi chekuti hapana kubuda kwemvura mukati nekunze kwevharuvhu, zvichiita kuti pave nekuchengetedzeka uye kuvimbika.
Kugara Kwenguva Refu: Chimiro chayo chepurasitiki hachidi mushonga wekudzivirira ngura, kudzivirira mvura, kana wekudzivirira kukwegura, uye chinogona kushanda kwemakore anosvika makumi mashanu pasi pemamiriro ekugadzira.
Kushanda Zviri Nyore: Huremu hudiki hune torque diki yekuvhura nekuvhara, uye hwakagadzirirwa chipanera chakatsaurirwa kuti chishande zviri nyore pasi.
Kuisa uye Kugadzirisa Zviri Nyore: Inogona kubatanidzwa nemapombi ePE uchishandisa nzira dzakajairwa dzemagetsi kana nzira dzekubatanidza mabutt, nekushanda zvakanaka kwekuvaka. Kugadzirisa nguva dzose kunoda kuvhurwa nekuvhara kwemwedzi mitatu yega yega.
Basa reKufefetedza Mapaipi Maviri: Rakabatanidzwa nemapaipi maviri ekufema, zvichiita kuti gasi rasara riburitswe zvakachengeteka muchikamu chepaipi chinodzika mushure mekuvhara vharuvhu huru, inova chinhu chakakosha chekuchengetedza pakugadzirisa, kugadzirisa, kana kugadzirisa nekukurumidza.
Mamiriro Ekushanda
Midziyo Inoshanda: Gasi rechisikigo rakacheneswa, gasi repeturu rakanyungudutswa, gasi rekugadzira, uye rakakodzerawo masisitimu emvura emumaguta.
Kumanikidzwa Kwezita: PN ≤ 0.5 MPa (inoenderana nekumanikidzwa kwesystem yemapaipi ePE yakabatana), ine kumanikidzwa kwakanyanya kushanda ka1.5 kupfuura kumanikidzwa kwekuyedza kwekuvharira (kusvika ku1.2 MPa) zvichienderana nezvinodiwa nenyika dzese, uye bvunzo yekuvharira yekumanikidzwa yakaderera ye28 KPa zvichienderana nezvinodiwa neASME kuti ione kushanda kwevharuvhu uye simba rayo.
Tembiricha yekushanda: -20°C kusvika +40°C (kumanikidzwa kwekushanda kunobvumirwa patembiricha dzakasiyana kunofanirwa kutevedzera mitemo yePE inoenderana nemidziyo yepombi).
Dhayamita Yezita (dn): Inowanikwa mumhando dzakasiyana-siyana, dzinosanganisira 32, 40, 50, 63, 75, 90, 110, 125, 160, 180, 200, 250, 315, 355, uye 400.

Kubata uye Kuongorora
Pakubata mavharuvhu, anofanira kusimudzwa oiswa zvinyoro nyoro. Zvinorambidzwa zvachose kurovera kana kurova chero chikamu chemuviri wevharuvhu kudzivirira kukuvara. Usati waisa, mashandiro evharuvhu anofanira kuongororwa. Nzvimbo yekuyedza inofanira kunge iri mhepo kana nitrogen, uye zviri mukati mekuongorora zvinofanira kusanganisira kuvharwa kuruboshwe, kuvharwa kurudyi, uye kushanda kwekuvhara kwakazara, izvo zvinofanirwa kutevedzera mwero weGB/T13927-1992.
Nzvimbo yekuisa
Mavharuvhu anofanira kuiswa pahwaro hwakasimba, uye panguva yekuisa, vharuvhu inofanira kunge yakavhurika zvizere.
Kuchenesa Mapaipi
Usati wabatanidza vharuvhu, pombi inofanira kuputirwa zvakasimba uye kucheneswa kudzivirira ivhu, jecha, nezvimwe tsvina kuti zvisapinde mugwara revharuvhu, izvo zvinogona kukonzera kukuvara mukati.
Nzira yekubatanidza
Kubatana pakati pevharuvhu nepaipi yepolyethylene (PE) kunofanirwa kuitwa nekubatanidza butt fusion kana electrofusion, uye kunyatsotevedzera "Technical Rules for Welding of Polyethylene Gas Pipelines" (TSG D2002-2006).
Kuiswa kweSleeve Inodzivirira
Vharuvhu ine chivharo chekudzivirira (kusanganisira chivharo chekudzivirira) uye chipanera chekushandisa. Hurefu hwakakodzera hwechivharo chekudzivirira hunofanira kusarudzwa zvichienderana nekudzika kwegomba. Pakuisa chivharo chekudzivirira, iva nechokwadi chekuti divi remuseve pachivharo chekudzivirira rinoenderana negwara rekuvhura kwepombi yePE uye kuvhura kwechigaro chepasi chechivharo chekudzivirira, wobva wabatanidza chivharo chekudzivirira chakamira nevharuvhu chivharo chekushanda wochigadzirisa zvakasimba.
Kushanda kweVhuruvhu Yekubuda Kwemhepo
Kana vharuvhu ine vent mbiri kana imwe chete ikashandisa, matanho ekushanda ndeaya anotevera: Kutanga, vhara vharuvhu huru zvizere, wobva wavhura chifukidziro che outlet valve, wobva wavhura vharuvhu ye outlet kuti ibudise; mushure mekunge vent yapera, vhara vharuvhu ye outlet wovhara chifukidziro che outlet. Cherechedza: Outlet valve ye vent inongoshandiswa chete pakutsiva gasi, kutora sampuro, kana kubatanidza kune flare. Zvinorambidzwa zvachose kuishandisa pakuongorora kumanikidzwa kwesystem, kuputira, kana kutora gasi, zvikasadaro inogona kukuvadza vharuvhu uye kukonzera tsaona dzekuchengetedza.
Zvinodiwa pakuzadza mari
Nzvimbo iri kunze kwechidzitiro chekudzivirira inofanira kuzadzwa nevhu rekutanga kana jecha risina matombo, magirazi, kana zvimwe zvinhu zvakaoma kudzivirira kukuvara kwechidzitiro chekudzivirira nevharuvhu.
Magadzirirwo ekushanda
Vharuvhu inongobvumirwa kushandiswa yakavhurika kana yakavharwa zvizere. Zvinorambidzwa zvachose kuishandisa kudzora kumanikidzwa kana kudhonza. Paunenge uchishanda, shandisa chipanera chinoenderana. Kutenderera newachi ndeyekuvhura, uye kutenderera newachi ndeyekuvhara.
