Malingana ndi kutentha kwa kutentha, epoxy powder ❖ kuyanika ndi polyurea anti-corrosion ❖ angagwiritsidwe ntchito nthawi zambiri m'malo owononga nthaka kuyambira -30 °C kapena -25 °C mpaka 100 °C, pamene polyethylene yokhala ndi zigawo zitatu. Kutentha kwakukulu kwa ntchito ya anti-corrosion ℃ ndi 70 ℃.Pankhani ya makulidwe okutira, kupatula zokutira ziwiri za ufa wa epoxy, makulidwe a zokutira zina zitatuzo zonse zili pamwamba pa 1mm, zomwe ziyenera kugawidwa m'gulu la zokutira zokhuthala.
Chimodzi mwazinthu zamtundu wa kupaka mapaipi ndi makina ndi mawonekedwe a zokutira, ndiye kuti, momwe zinthu ziliri zomwe zingakumanepo pomanga mapaipi, monga kulingalira kupindika kwa payipi mutatha kuwotcherera ndikukweza pansi. dzenje pomanga mapaipi aatali.Zinthu zotsutsana ndi kutentha kwapang'onopang'ono zimapangidwira molingana ndi ma diameter osiyanasiyana, kukana kwapaipi kumatsimikiziridwa ndi kuwonongeka kwapaipi komwe kumachitika chifukwa cha kayendedwe ka mapaipi ndi kubweza kumbuyo, kukana kukankha ndi kukana kwa zokutira kumatsimikiziridwa ndi zokopa ndi abrasions pamene mapaipi akudutsa.Valani kukana, ndi zina zotero. Kuchokera pamalingaliro azinthu izi, ziribe kanthu kupaka ufa wa epoxy, mawonekedwe atatu osanjikiza kapena kupaka polyurea, onse ali ndi ntchito yabwino, koma ponena za makulidwe a ❖ kuyanika, polyethylene yamagulu atatu ali ndi mphamvu yotsutsa kwambiri, pamene kupopera mbewu mankhwalawa Mphamvu yochepa kukana mtengo wa 14.7J kwa polyurea zoteteza ❖ kuyanika ndi zabwino kwambiri.

Popeza ❖ kuyanika kwa mapaipi akutali nthawi zambiri amagwiritsidwa ntchito limodzi ndi chitetezo cha cathodic, kapangidwe kakekupaka payipizizindikiro zimayang'anitsitsa kwambiri zotsutsana ndi cathodic disbondment ntchito ya zokutira, motero amakhazikitsa mapulojekiti afupikitsa komanso apakati otsutsana ndi cathodic disbondment, poganizira kugwiritsa ntchito mapaipi aatali.Kutentha kotero kumayika projekiti yotentha kwambiri ya cathodic disbondment.Kuchokera pamawonedwe a ndondomeko, zikuwonekeratu kuti ndondomeko yotsutsana ndi cathodic disbondment ya epoxy ❖ kuyanika ndipamwamba, kutayika kwakukulu kwa cathodic ndi 8.5mm pa kutentha kwa 28d, ndipo kutayika kwakukulu kwa cathodic pa kutentha kwakukulu ndi 6.5mm pa 48h. .Zizindikiro za zokutira urea ndizotayirira, 12mm ndi 15m motero.
