Mapaipi okhala ndi zokutira za Anti-corrosion

Miyezo: Miyezo ya mapaipi otchinga odana ndi dzimbiri amakhazikitsidwa ndi mabungwe monga American Society for Testing and Materials (ASTM), International Organisation for Standardization (ISO) ndi National Society of Corrosion Engineers (NACE). Miyezo iyi imatchula zofunikira pazida zokutira, njira zogwiritsira ntchito, njira zoyesera ndi miyezo yogwirira ntchito.

Magulu otengera chithandizo chapamwamba: Mapaipi okhala ndi anti-corrosion anti-corrosion amatha kugawidwa potengera mtundu wa zokutira zomwe zimagwiritsidwa ntchito. Magulu odziwika bwino ndi awa: Kupaka kwa Fused Bonded Epoxy (FBE) Kupaka Polyethylene (PE) kapena polypropylene (PP) Kupaka Phula kapena phula lopaka Zinc utoto wolemera wa Polyurethane wokutira Malasha phula enamel yokutira.

Mapulogalamu: Mapaipi okhala ndi zokutira odana ndi dzimbiri amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza: Mafuta ndi Gasi: Mapaipi omwe amagwiritsidwa ntchito kunyamula mafuta osakanizika, gasi wachilengedwe ndi zinthu zamafuta Madzi ndi madzi otayira: madzi apansi panthaka ndi m'mipaipi Chemical and petrochemical: ponyamula mankhwala owononga ndi acids Marine ndi m'mphepete mwa nyanja: kwa mapaipi apansi pa nyanja ndi zomanga za m'mphepete mwa nyanja Zomangamanga: Zogwiritsidwa ntchito pa milatho, madoko ndi zinthu zina zomwe zimakumana ndi zovuta zachilengedwe Mipope iyi ndi yofunika kwambiri kuti pakhale kukhulupirika ndi moyo wautali wa zomangamanga ndi mafakitale, makamaka m'malo ovuta kapena owononga. Pofotokoza kapena kusankha chitoliro chokhala ndi anti-corrosion, ndikofunikira kutchula miyezo yoyenera ndikukambirana ndi akatswiri amakampani kuti awonetsetse kuti zokutira zomwe zasankhidwa zikukwaniritsa zofunikira zomwe mukufuna.
