PE mapaipianoshandiswa zvakanyanya muhupenyu hwedu uye anoita rimwe basa.Kuti ushandise zvirinani uye kuchengetedza chigadzirwa ichi, zvinonyanya kukosha kuti unzwisise ruzivo rwakakodzera rwePE pombi corrosion.
Kurwiswa kwemakemikari: Kurwiswa kwemakemikari kwepepi yePE kunokonzerwa nekurwiswa kwakananga kwechiito chemakemikari akachena pakati pechitarisiko chesimbi uye kwete-electrolyte.Kureva kuti, mushure mekunge simbi yasangana nepakati, iyo ablation process yeioni yesimbi inoitika zvakafanana pamusoro pesimbi, uye ablation kukurumidza kunonoka.
Electrochemical corrosion: Kukuvadzwa kunokonzerwa neelectrochemical corrosion of the metal surface uye electrochemical action yeionic conductive medium yePE pombi ndeyekuti simbi ye electrolysis process inoitika mubhatiri rekutanga rinoumbwa nesimbi uye electrolyte.Chero kupi zvako, mhinduro yecorrosion maererano ne electrochemical mechanism ine inokwana imwe inodic mhinduro uye imwe cathodic mhinduro yakabatanidzwa nekuyerera kwema electrons kuburikidza nesimbi uye kuyerera kweion mukati mepakati.
Kukukurwa kweBhakitiriya: Iyo nzira yekukukurwa kwehutachiona hwesimbi yakaoma, asi mune dzimwe ivhu, marudzi matatu emabhakitiriya anobatanidzwa mukukukurwa kwevhu: mabhakitiriya anoderedza sulfate, mabhakitiriya e-sulfur-oxidizing, uye mabhakitiriya esimbi.
PE pombi ndeye polyethylene epurasitiki pombi chigadzirwa, chikonzero nei vanhu vachisarudza iyi pombi ndeyekuita kwayo kwepamusoro uye mutengo wakaenzana.Kuiswa kwemapombi ePE kuri nyore uye nekukurumidza, nekukuvara kwakaderera uye mari yekugadzirisa.Chero bedzi iyo yakabatana yakanaka, inogona kumira axial mitoro isina kubuda.
Nekuda kweizvozvo, anchor mapoinzi uye piers pamajoini uye mabhendi hazvidiwi kuisa, kuderedza mutengo.Polyethylene (PE) zvinhu zvinoshandiswa zvakanyanya mumunda wekugadzira pombi yekupa mvura nekuda kwesimba rayo rakawanda, kusagadzikana kwekuora uye kusaita chepfu.Iyo haizoite ngura uye chigadzirwa chakanakira kutsiva zvakajairika iron yekupa mvura pombi.
Panguva imwecheteyo, nekuda kwehuremu hwayo huremu, kusimba kwakanaka, kupikisa kwakanaka, mutengo wakachipa uye yakanaka yakaderera tembiricha kuramba, mapaipi ePE parizvino anoshandiswa zvakanyanya mukuvaka kwemasipala, zvivakwa, uye mafekitori.PE pombi zvigadziriso zvine hushamwari uye zvakatipoteredza, uye hapana chepfu chekuwedzera chinowedzerwa panguva yekugadzira.Chimiro chemukati wemadziro epipeline chakatsetseka, chisina kuyera uye mabhakitiriya, uye kugadzirwa, kubatanidza uye tekinoroji yekuvaka yakakura.Zvinoenderana neayo emuviri uye emuchina zvivakwa, inotora inopisa melt yekubatanidza kana flange inotsigira yekubatanidza, iyo ine kuomarara kwakanyanya, yakavimbika kubatana, kuvakwa kuri nyore, yakakwirira yekudzivirira coefficient uye yakaderera leakage rate.
