Kukwidziridzwa muSimbi Pipe Anticorrosion Tekinoroji Dzivirira Kuchengetedzeka uye Hupenyu Hurefu hweIndasitiri Yekufambisa
Munzvimbo yepetrochemical, yemaguta ekupa mvura, uye magasi ekufambisa gasi, mapaipi esimbi, semota dzekufambisa dzepakati, anogara achisangana nematambudziko akawanda, anosanganisira kukoromoka kwevhu, kukukurwa kwemedia, uye oxidation yemhepo. Dhata rinoratidza kuti avhareji yehupenyu hwesevhisi yepombi dzesimbi dzisina kugadzirwa isingasviki makore mashanu, nepo iyo yeyakajairwa anticorrosion kurapwa inogona kuwedzerwa kusvika anopfuura makore makumi maviri. Nekuvandudzwa kwemaindasitiri uye nekuwedzera zvinodiwa zvekuchengetedza nharaunda, tekinoroji yesimbi inodzivirira kupisa yakashanduka kubva pakudzivirira-yekuvharisa kusvika kune imwe nhanho yekudzivirira-hupenyu huzere hunosanganisira "kukwidziridzwa kwezvinhu, kugadzirisa maitiro, uye nehungwaru kutarisa."
Parizvino, mainstream simbi pombi anticorrosion tekinoroji inopa akasiyana siyana masisitimu akarongedzerwa kune chaiwo mamiriro ekushandisa. Muchikamu chepombi yakavigwa, 3PE (matatu-layer polyethylene coating) anti-corrosion coatings ndiyo inosarudzika mhinduro yemapombi akareba emafuta uye gasi nekuda kwekupokana kwavo kwakanyanya kushushikana kwevhu uye cathodic disbonding. Chimiro chavo chakaumbwa, chinosanganisira base epoxy poda, chinonamira chepakati, uye chekunze chepolyethylene layer, chinopa zvese ngura uye kudzivirira kwemhedzisiro. Kune mapombi easidhi uye alkaline muindasitiri yemakemikari, fluorocarbon coatings uye epurasitiki lining zvinopa zvakanakira. Iyo yekutanga inokwirisa kemikari inertness yefluororesins kuti irambe inoparadza zvakanyanya media, nepo iyo yekupedzisira inoparadzanisa media inotakurwa kubva mupombi yesimbi pachayo nekumisa madziro emukati nezvinhu zvakaita se polyethylene uye polytetrafluoroethylene. Uyezve, kupisa-dip galvanizing inoshandiswa zvakanyanya munzvimbo dzakapfava dzinotyisa senge yekanzuru yemvura uye madhiraini masisitimu uye masisitimu esimbi anotsigira nekuda kwemutengo wakaderera uye nyore kuisirwa. Chibayiro cheanodic chiito che zinc layer chinopa kuchengetedzwa kwenguva refu kwe electrochemical yepombi yesimbi.
Kukwidziridzwa kwetekinoroji uye kuvandudzwa kwemaitiro kuri kutyaira kuvandudzwa kwemhando yesimbi pombi anti-corrosion. Tsika dzechinyakare dzemanyorero ekupendi, nekuda kwenyaya dzakaita senge kusaenzana kwehukukutu hwekunamira uye kusanamira zvakanaka, zvishoma nezvishoma zviri kutsiviwa neotomatiki mitsara yekugadzira. Parizvino mainstream electrostatic spraying uye airless spraying matekinoroji anogona kuwana coating ukobvu kushivirira mukati ± 5%. Mumunda wezvinhu zvinorwisa-corrosion, zvakatipoteredza mvura-based epoxy coatings uye graphene-modified anti-corrosion coatings zvishoma nezvishoma zviri kutsiva solvent-based coatings, kuderedza kuburitsa kweVOC uku ichivandudza kumira kwemamiriro ekunze uye nekupfeka. Panguva imwecheteyo, nzira dzehungwaru dzekutarisa dziri kutanga kubatanidzwa mune anti-corrosion system. Mapombi esimbi mune mamwe mapurojekiti akakosha ave kugadzirirwa corrosion sensors. Masensa aya anounganidza chaiyo-nguva yecorrosion ikozvino uye yekuvharisa masaini masaini kubva kumadziro ekunze kwepombi, zvichigonesa yambiro yekukurumidza yekutadza kukanganisa uye kugadzirisa chaiko.
Kune mapurojekiti esimbi epombi ekurwisa ngura, chibvumirano cheindasitiri ndechekuti "30% zvinhu, 70% kuvaka." Pamberi pekuvaka, iyo pombi yesimbi yepamusoro inofanira kunge yakaputirwa nejecha kuti ibvise ngura uye ive nechokwadi chekuoma kwepamusoro kweSa2.5 kana kupfuura. Mushonga uyu unobvisawo tsvina yakaita semafuta, chikero, nezvimwe zvitsvina, zvichigadzira nzira yekunamira. Panguva yekuvaka, ukobvu hwekuputira, tembiricha yekurapa, uye nguva inofanirwa kudzorwa zvakanyanya kudzivirira hurema hwakadai semapini uye kudonha kwekuvhara. Mushure mekupedza, iyo anti-corrosion kushanda kunofanirwa kusimbiswa kuburikidza nenzira dzakadai sekuyedza spark uye kuyedzwa kwekunamatira. Chete nekutanga yakazara, yakavharwa-loop maitiro anosanganisira "material kusarudzwa - pamusoro pekurapa - kuvaka manejimendi uye kutonga - post-kugadzirisa" kunogona kuve kwenguva yakareba kukosha kwesimbi pombi anti-corrosion kunyatsoitika.
Nekufambira mberi kwezvinangwa zve "dual kabhoni" uye nekuwedzera zvinodiwa zvekuchengetedza maindasitiri, tekinoroji yesimbi inorwisa-corrosion tekinoroji icharamba ichishanduka ichienda kune yakasvibira, inoshanda, uye nehungwaru nzira. Mune ramangwana, zvinhu zvitsva zvinorwisa-corrosion zvinosanganisa zvinhu zvakaderera-kabhoni nekudzivirira kwenguva refu, pamwe neanti-corrosion yekutarisa masisitimu anobatanidza dhijitari twin tekinoroji, ichava yakakosha indasitiri yekutsvaga uye kusimudzira. Izvi zvinopa nhovo yakasimba yekuchengetedza mapaipi akasiyana-siyana emaindasitiri uye kubatsira mukushanda kwepamusoro-soro kwezvivakwa.
