Kusanthula Kwathunthu kwa Njira Zodzitetezera Pogwiritsira Ntchito Anti-Paipi ya Zitsulo Zowonongeka
Chifukwa cha kulimba kwake kwa dzimbiri, chitoliro choletsa -chitsulo cha chitsulo chimagwiritsidwa ntchito kwambiri m'mafakitale a petroleum, chemical, gasi, ndi madzi. Komabe, kunyalanyaza njira zazikulu zodzitetezera pakagwiritsidwe ntchito kungayambitse kulephera kwa anti-kutchingira dzimbiri, kufupikitsa moyo wa chitoliro ngakhalenso kuyambitsa ngozi. Tsatanetsatane wa njira zodzitetezera pogwiritsira ntchito -paipi yachitsulo yowononga dzimbiri kuchokera m'mbali zinayi: mayendedwe, kukhazikitsa, kugwira ntchito, ndi kukonza.
I. Mayendedwe: Pewani Kuwonongeka Mwakuthupi
Anti{0}} corrosion coating of anti-corrosion steel pipe (monga 3PE, epoxy powder, etc.) imaonongeka mosavuta ndi kuwombana, kupindika, kapena kupanikizidwa paulendo. Chifukwa chake, zindikirani:
Kuyika Moyenera: Gwiritsani ntchito zothandizira zodzipereka kapena zochepetsera zofewa kuti muteteze chitoliro chachitsulo ndikupewa kukhudzana mwachindunji ndi zinthu zolimba. Gwiritsani ntchito ngakhale mphamvu pomanga kuti musamangidwe pakhosi.
Kuteteza ku mvula ndi chinyezi: Phimbani ndi nsaru yotchinga madzi mukamayenda, makamaka zomatira za epoxy-zochokera ku-zoletsa dzimbiri, chifukwa kukhudzana ndi madzi kumachepetsa kumatira kwake.
Kwezani ndi Kuyika Mwachisamaliro: Gwiritsani ntchito ma gulayeni odzipereka pokweza, ndipo pewani kukhudzana mwachindunji pakati pa chingwe cha waya ndi chitoliro. Mfundo zokweza ziyenera kupewa ma welds kapena malo ofooka mu zokutira.
II. Njira Yoyikira: Kuchepetsa Zowonongeka
Kuyika ndi gawo lowopsa-loopsa kwambiri pakuwonongeka kwa -kutchingira kwa dzimbiri. Samalani kwambiri izi:
Chitetezo cha Pipe: Musanadule kapena kuwotcherera, sungani zotchingira zoletsa-zidzimbiri papaipi kumapeto kwake ndi tepi kapena zotsekera zapulasitiki kuti zisapse ndi moto.
Zofunikira pa kuwotcherera: Ngati -pamafunika kuwotcherera pamalo, siyani kusiyana kwa 10-15cm pakati pa seam ndi zokutira zoletsa kuwononga. Ikaninso zokutira mukamaliza kuwotcherera. Kugwira ntchito mumvula, matalala, kapena malo okhala ndi chinyezi chopitilira 85% ndikoletsedwa.
Malangizo Ogwirira Ntchito: Valani magolovesi mukamagwira ntchito pamanja kuti musachite dzimbiri kuchokera ku thukuta la m'manja. Pamakina akugwira, sinthani malo odzigudubuza kuti mupewe kupindika ndi kupindika kwa chitoliro.
III. Gawo la Ntchito: Kuwongolera Chilengedwe ndi Kupanikizika
Kugwira ntchito-kwanthawi yayitali kwa anti{1}}anti corrosion steel pipe kumagwirizana kwambiri ndi malo ogwirira ntchito:
Media Compatibility: Tsimikizirani kuti njira yotumizira zinthu (monga madzi acidic ndi amchere, -nthunzi yotentha kwambiri) ikugwirizana ndi-zopaka dzimbiri. Mwachitsanzo, ufa wa epoxy ndi asidi-wosamva koma osamva zosungunulira zolimba.
Kutentha ndi Kuchepetsa Kupanikizika: Tsatirani mosamalitsa magawo apangidwe. Kutentha kwambiri kungapangitse kuti zokutira zifewetse ndikugwa, ndipo kuthamanga kwambiri kungayambitse kupsinjika maganizo. Kugwirizana kwa Chitetezo cha Cathodic: Mapaipi okwiriridwa amafunikira kuyezetsa nthawi zonse mphamvu ya chitetezo cha cathodic (nthawi zambiri -0.85V mpaka -1.2V) kuti zitsimikizire chitetezo cha electrochemical pamalo owonongeka a anti-corrosion.
IV. Kusamalira ndi Kuyang'anira: Konzani Zowonongeka Mwamsanga
Kusamalira nthawi zonse kumatha kukulitsa moyo wa -paipi zachitsulo zowononga dzimbiri kangapo:
Kuyang'anira Mawonekedwe: Yang'anani nsabwe za m'maso kuti zikuvundikire, kung'ambika, kapena kusenda pafupifupi chaka chilichonse, kuyang'ana kwambiri madera opanikizika monga ma welds ndi zigongono.
Mayeso a Electro-spark: Mapaipi okwiriridwa akuyenera kuyang'aniridwa kuti aone ngati mapiniwo ali mu zokutira pogwiritsa ntchito electro-spark tester 2-zaka zitatu zilizonse. Zotulukapo ziyenera kukonzedwa ndi penti yoletsa dzimbiri kapena tepi yochepetsa kutentha.
Kuyeretsa Chilengedwe: Chotsani udzu ndi zowononga (monga saline-dothi la alkali) mozungulira mapaipi kuti mupewe kuwonongeka kwa microbiologically influenced corrosion (MIC).
Mapeto
Ubwino wa magwiridwe antchito a -mapaipi achitsulo owononga dzimbiri amadalira kasamalidwe koyenera komanso koyenera. Kutsatira mosamalitsa njira zomwe zili pamwambazi pagawo lililonse, kuyambira pamayendedwe mpaka kukayidwa, kumapangitsa kuti dongosololi likhale ndi chitetezo chokwanira komanso chokhazikika. Pazinthu zapadera zogwirira ntchito (monga nyanja yakuya ndi malo a asidi amphamvu), tikulimbikitsidwa kuti mufunsane ndi wopanga njira zothetsera makonda ndipo musagwire ntchito mwakhungu.
