Sechinhu chakakosha muinjiniya yepombi yemazuva ano, pombi dzesimbi dzinodzivirira -kuora dzinoshandiswa zvakanyanya mumaindasitiri eoiri, gasi, makemikari, nemvura nekuda kwekusakara kwadzo uye kurarama kwenguva refu. Mamiriro avo ehunyanzvi anonyanya kuratidzwa muzvikamu zvitatu: anti-kugadzira corrosion coating, kusarudza zvinhu, uye process innovation.
Chekutanga, anti-corrosion coating of anti-corrosion steel pipes ndiyo yakakosha tekinoroji. Nzira dzekudzivirira -kuora dzinosanganisira nhatu-layer polyethylene (3PE), epoxy coal tar, uye polyurethane coatings. Iyo 3PE anti-corrosion coating inosanganisa kunamira kwakasimba kweepoxy powder, shanduko yezvinonamira, uye kusimba kwepolyethylene kuti iite multi-layer inodzivirira inopikisa ivhu, mwando, uye makemikari media. Epoxy poda coatings, kuburikidza{11}}kupisa kwekushisa kwepamusoro, anoumba firimu rakadzivirirwa rinoenderana ne{12}}tembiricha yepamusoro uye{13}}nzvimbo dzekudzvanya. Pamusoro pazvo, kushandiswa kuchangoburwa kwenano{15}}modified anti{16}}coatings yecorrosion kwawedzera kunatsurudza kupenya kwependi uye kusamira kwemamiriro ekunze.
Chechipiri, kusarudzwa kwezvinhu zvepasi zvepombi-zvinoita corrosion simbi zvinokanganisa kushanda kwawo kwese. Seamless uye welded simbi mapaipi ndiwo makuru marudzi pombi. Mapombi esimbi asina musono, nekuda kwekushaikwa kwemaweld uye kusimba kwakanyanya, anowanzo shandiswa pakufambisira-pressure. Mapombi esimbi akaiswa simbi, anoshandisa-frequency welding kana submerged arc welding process kuti kuderedze mitengo, akakodzera kushandiswa kwese. Kuwedzera dziviriro yecorrosion, mamwe mapaipi esimbi ane galvanized kana simbi isina tsvina, asi izvi zvinodhura uye zvinonyanya kushandiswa munzvimbo dzakashongedzwa.
Chekupedzisira, kuvandudzwa kwe-maitiro ekuora ndiko kwakakosha pakuvandudza tekinoroji. Physical anti-nzira dzekudzivirira ngura dzakaita searc spraying nekupisa-dip galvanizing zvinosanganiswa nemakemikari coatings kuita composite protection system. Uyezve, kushandiswa kwekathodic kuchengetedza tekinoroji, uchishandisa yakakatyamadzwa yazvino kana yekupira anode, inowedzera hupenyu hwemapombi esimbi. Kuunzwa kweautomated spraying uye neungwaru kuona matekinoroji kunoita kuti pave nekufanana uye kusachinja-chinja kwemhando yeanti-kupora kwecorrosion.
Muchidimbu, kuburikidza-nemadhizaini anodzivirira kukorona-akawanda,{2}}zvemhando yepamusoro, uye mashandiro epamusoro, pombi dzinodzivirira{3}}kuora kwesimbi dzinokwanisa kusaora, hupenyu hurefu hwesevhisi, uye kudhura kwekugadzirisa, zvichiita kuti dzive sarudzo yakakosha yekugadzira mapurojekiti epombi echizvino-zvino.
