Gasi remusikirwo isimba rakachena, rinoshanda, rakanakira uye remhando yepamusoro uye makemikari zvinhu.Kushandiswa kwayo uye kushandiswa kune zvakakosha zvehupfumi, zvemagariro uye zvakatipoteredza.Nekumwe kuvandudzwa kweChina gasi rechisikigo, indasitiri yegasi ichasangana nemikana mitsva, yakatarisana nematambudziko matsva.Iko kushandurwa kweiyo yekutanga pombi network kana kuisa pombi nyowani network kunofanirwa kusimbisa kuchengetedzwa, kubvisa njodzi yese.Sezvinogona kuonekwa kubva kune pombi network kumba nekune dzimwe nyika, chikonzero chetsaona, yakakonzerwa netsaona dzinoparadza dzevanhu dzakakonzera kukanganisa kwepipeline corrosion (kusanganisira stress corrosion cracking) panzvimbo yechipiri.Iwo ekupedzisira anowanzo kunetsa kuona, kazhinji kufuratirwa, kuparara kwepombi pasina mubvunzo yakakosha agenda inofanira kutaurwa.

Iyo yakakwira anticorrosion coating application
Nzira dzekutanga dzekumba uye dzepasirese pasi pevhu gasi pombi yekuora kwakakodzera zvichienderana nepombi iyo geographical terrain, topography, geological mamiriro, kufukidza kunowedzerwa necathodic kuchengetedzwa.Pendi yakashandiswa: petroleum asphalt, coal tar enamel, epoxy pendi.Domestic yakavigwa pombi anti-corrosion inowanzoshandiswa petroleum asphalt pendi.Kana nharaunda yevhu, microbial, pasina kukanganiswa kwakakomba nembeu yakadzika midzi, ichionekwa seyakatengwa inodzivirira-corrosion layer.Kuyerera kwaro zvinhu hazvina kukodzera kumhepo yepamusoro-soro uye kusvibiswa kwakakomba kwezvakatipoteredza panguva yekuvaka, kushandiswa kwayo kwakaratidza kuderera.Kubva pakuona kwepasirese, inonyanya kushandiswa kana kusunda marasha tar enamel uye epoxy pendi.Iyo yekutanga ine yakasimba anti-microbial corrosion, anti-chirimwa midzi kupinda, yakaderera kunyura kwemvura, kuramba kune cathodic delamination, bonding yakaputirwa yakasimba yakasimba pamadziro, pane zviri pachena zvakanakira kushandiswa mupombi yemafuta negesi The United States, Russia. , mukushandiswa kukuru.

Pipeline yekuputira pamberi pepamberi pretreatment process kuvandudzwa
Hunhu hwekuchengetedza hunoenderana nemwero weiyo yakavharwa yepamberi pekutanga pretreatment nzira yekusarudzwa.Iyo yechinyakare inobvisa ngura Mutemo wenguva uye kusvibiswa kwevashandi wakaoma kuvimbisa kunaka.Mumakore achangopfuura tsika yekushandisa tembiricha isina kuvhenekerwa mutemo degreasing, iyo pombi inorodha muchoto chakanyanya pa350 ~ 400 ℃ inowedzerwa nemhepo, insulation 3 ~ 4 h, mafuta akapisa vimbiso yekudzikisa kunaka.Peening michina panzvimbo yechinyakare nzira pickling.Iyi nzira ndeye kushandiswa kwemhepo yakamanikidzwa kutakura simbi yepfuti (kana jecha) kuti iite kuyerera kwepamusoro-kumhanya kwezvinhu zvine simba pamusoro pesimbi kuburikidza nemuromo wepfuti kubvisa oiri kana oxide.Iyo inoita ngura zvachose, asi zvakare inonatsiridza kushata kwepamusoro, kuwedzera nzvimbo yekusangana yemadziro uye yekupotera (kanenge ka20), uye kugadzirisa coating bond simba, inogona kudzivirirwa zvakadzika delamination.
