Mu makampani opanga mafuta, dzimbiri la mapaipi limakhala pachiwopsezo chachikulu pa chitetezo cha ntchito, kuteteza chilengedwe, komanso kugwiritsa ntchito bwino ndalama. Mapaipi nthawi zambiri amanyamula zinthu zowononga monga mafuta osakonzedwa, gasi wachilengedwe, mankhwala a sulfure, ma acid, ndi alkali, zomwe zimapangitsa kuti kupewa dzimbiri la mapaipi kukhala chinthu chofunikira kwambiri paukadaulo. Nkhaniyi ikufotokoza njira zothandiza kwambiri zopewera dzimbiri m'mapaipi a petrochemical, kuphatikizapo kusankha zinthu, kuteteza pamwamba, kuteteza cathodic, ndi kuyang'anira dzimbiri.
Kusankha Zinthu: Mzere Woyamba wa Chitetezo
Kusankha zipangizo zosagwira dzimbiri kumawonjezera nthawi yogwira ntchito ya mapaipi. Zosankha zodziwika bwino ndi izi:
| Zinthu Zofunika | Mtundu | Zinthu Zofunika Kwambiri | Malo Ogwiritsira Ntchito |
|---|---|---|---|
| 316L | Chitsulo Chosapanga Dziwe cha Austenitic | Kukana bwino kuyika mabowo; kusunthika | Kupezeka kwa asidi, chloride |
| S32205 / S32750 | Duplex / Super Duplex | Mphamvu yayikulu, kukana kwabwino kwa chloride | Mapaipi a m'nyanja, amadzi amchere |
| Inconel 625 / 825 | Aloyi wa nikeli | Kukana kwakukulu kwa asidi amphamvu ndi alkali | Kuchotsa sulfur, machitidwe otentha kwambiri |
| Chitsulo cha Carbon chokhala ndi Ma Linings | Chitsulo Chokhala ndi Mizere | Yotsika mtengo, dzimbiri lotetezedwa ndi denga | Mafuta olemera mu sulfure, mizere yotsika ya mpweya |
Kuphimba Pamwamba: Chotchinga Chakuthupi Cholimbana ndi Kudzimbiri
Zophimba zakunja ndi zamkati zimapereka chotchinga choteteza ku zinthu zowononga:
• Chophimba cha epoxy cha phula la malasha:Njira yachikhalidwe yopangira mapaipi obisika.
• Fusion Bonded Epoxy (FBE):Kukana kutentha kwambiri komanso kumamatira mwamphamvu.
• Chophimba cha PE / PP cha zigawo zitatu:Amagwiritsidwa ntchito kwambiri pa mapaipi otumizira mauthenga akutali.
Zophimba mkati: Zimachepetsa kukana kwa madzimadzi ndikuteteza ku dzimbiri la mkati mwa khoma.
Kukonzekera bwino malo ndi kugwiritsa ntchito ndikofunikira kwambiri kuti zophimba izi zigwire bwino ntchito.
Chitetezo cha Cathodic: Ukadaulo Wotsutsana ndi Kutupa kwa Magetsi
Chitetezo cha cathodic chimaletsa dzimbiri la electrochemical mwa kukakamiza pamwamba pa payipi kuti pakhale ngati cathode:
• Dongosolo la Anode Yoperekedwa: Limagwiritsa ntchito anode za zinc, magnesium, kapena aluminiyamu.
• Dongosolo la Mphamvu Yodabwitsa: Imagwiritsa ntchito gwero lamagetsi lakunja kuti igwiritse ntchito mphamvu.
Njira imeneyi imagwiritsidwa ntchito kwambiri m'mapaipi obisika ndi pansi pa nyanja, nthawi zambiri amaphatikizidwa ndi zokutira kuti agwire bwino ntchito.
Kuyang'anira ndi Kusamalira Kudzimbiri
Kuwunika nthawi zonse kumathandiza kuzindikira dzimbiri msanga, kuchepetsa zoopsa zolephera:
• Ma Probes Olimbana ndi Magetsi ndi Kuwunika Phokoso la Electrochemical kuti liwunike nthawi yeniyeni;
• Kuyeza Kukhuthala kwa Ultrasonic kuti mupeze kupendekeka kwa khoma;
• Makuponi a dzimbiri kuti ayese kuchuluka kwa dzimbiri pakapita nthawi.
Kukhazikitsa kuyendera nthawi zonse, nthawi yoyeretsera, ndi mankhwala othandizira kumathandiza kusunga umphumphu wa mapaipi.
Kutsatira Miyezo ya Makampani
Onetsetsani kuti kapangidwe ka mapaipi anu ndi njira zotetezera zikugwirizana ndi malamulo apadziko lonse lapansi:
ISO 21809 - Miyezo yophimba yakunja ya mapaipi m'mafakitale amafuta ndi gasi wachilengedwe;
NACE SP0169 - Njira zodzitetezera ku Cathodic;
API 5L / ASME B31.3 - Miyezo yomangira mapaipi ndi njira zogwirira ntchito.
Mapeto: Njira Yogwirizana Yotetezera Kwa Nthawi Yaitali
Chitetezo chogwira ntchito cha dzimbiri cha mapaipi chimafuna njira zosiyanasiyana, kuphatikizapo:
• Kusankha zinthu mwanzeru,
• Makina olimba ophikira,
• Chitetezo cha cathodic chogwira ntchito, ndi
• Mapulogalamu odalirika owunikira ndi kukonza.
Mwa kugwiritsa ntchito njira yonse yoyendetsera dzimbiri, ogwira ntchito za petrochemical amatha kuchepetsa kutsekedwa kosakonzekera, kukulitsa nthawi yogwiritsira ntchito katundu, ndikuwonetsetsa kuti ntchito zake ndi zotetezeka komanso zogwira mtima.
