Anti- umbhobho yentsimbi isetyenziswa ngokubanzi kwi petroleum, imichiza, kunye namashishini igesi yendalo. Umgaqo wayo ongundoqo kukuthintela ukubola kunye nokwandisa ubomi bayo benkonzo ngeenkqubo ezikhethekileyo. Indlela yokufaka isicelo ngokuyinhloko ibandakanya amanyathelo amathathu abalulekileyo: unyango olungaphezulu, ukusetyenziswa kokugqoka, kunye nokuhlolwa.
1. Unyango loMphezulu
Inyathelo lokuqala lokusebenzisa umbhobho wentsimbi yokuchasana{0}}kukucoca ngokucokisekileyo umphezulu ukususa umhlwa, i-oyile, kunye ne-oxide layers. Iindlela eziqhelekileyo ziquka i-sandblasting (i-Sa2.5 okanye ngaphezulu) okanye i-chemical pickling ukuqinisekisa uburhabaxa obuthile bomphezulu wokuphucula ukunamathela kwi-coating. Anti{4}}unyango lomhlwa kufuneka lusetyenziswe kwiiyure ezi-4 zonyango ukuthintela i-oxidation yesibini.
2. Isicelo sokugquma
Iindlela ezahlukeneyo zokugquma ziyafumaneka kwi-anti{0}}yentsimbi yombhobho wentsimbi, kuquka itela yamalahle epoxy, i-3PE (ezintathu-zemaleko e-polyethylene), kunye ne-FBE (umgubo odityanisiweyo we-epoxy).
I-Epoxy coal tar: Ifakwe ngebrashi okanye isitshizi, iqulethe iidyasi ezimbini: i-primer kunye ne-topcoat, kunye nobukhulu obupheleleyo obungaphezulu okanye obulingana no-0.6mm. Ukunyanga kuyafuneka kwindawo efumileyo kangangeeyure ezingama-24 . 3I-PE Anticorrosion: Ukusebenzisa inkqubo yokujija, ukudityaniswa{4}}i-bond epoxy powder kuqala kugalelwe (i-base layer), kulandele i-adhesive kunye ne-polyethylene (umaleko wangaphandle), kunye nobukhulu bubonke be-Greater than or equal to 2.5mm. Ilungele imibhobho engcwatyiweyo.
I-FBE Anticorrosion: I-epoxy powder ifakwe ngokuthe ngqo kwi-electrostatically, inyibilika kumaqondo obushushu aphezulu ukwenza i-coating exineneyo. Ubukhulu buqhele ukuba yi-400-1000μm, enokumelana nobushushu obuphezulu.
3. Ukuhlolwa koMgangatho
Emva kokugqitywa, uhlolo olungqongqo luyafuneka, kubandakanywa ukuhlolwa okubonakalayo (kwi-bubbles kunye nokuqhekeka), ukulinganisa ubukhulu (ukuqinisekisa ukuthotyelwa kwemigangatho yoyilo), ukubonwa kwentlantsi (ukuqinisekisa ukuba akukho kuvuza), kunye nokuvavanya ukunamathela. Iindawo ezingafanelekanga kufuneka zilungiswe ngokukhawuleza ukuze kuqinisekiswe i-anticorrosion esebenzayo.
Izilumkiso: Nxiba izixhobo zokukhusela ngexesha lokusebenza ukuphepha ukudibanisa phakathi kwepeyinti kunye nolusu. Ubushushu be-ambient kufuneka bube phakathi kwe-5 kunye ne-40 degree, kunye nokufuma ngaphantsi kwe-85%. Ukusebenza ngokufanelekileyo kunokuphucula kakhulu ukuxhatshazwa kwe-corrosion yeepayipi zensimbi, ukuqinisekisa ukhuseleko lweprojekthi kunye nokuphila ixesha elide.
