Mai ka hiʻohiʻona o ka pae wela o ka uhi ʻana, hiki ke hoʻohana maʻamau ka uhi ʻana i ka pauka epoxy a me ka polyurea anti-corrosion coating i nā wahi ʻino lepo mai -30 °C a i ʻole -25 °C a i 100 °C, aʻo ka polyethylene ʻekolu-layer. ʻO ka mahana lawelawe kiʻekiʻe loa o ka uhi anti-corrosion he 70 ℃. Ma ke ʻano o ka mānoanoa o ka uhi ʻana, koe naʻe nā ʻāpana pauka epoxy ʻelua, ʻo ka mānoanoa o nā ʻāpana ʻekolu ʻē aʻe ma luna o 1mm, pono e hoʻokaʻawale ʻia i ka ʻāpana o nā uhi mānoanoa.
ʻO kekahi o nā mea maʻamau o ka pipeline coating standard ka mechanical and physical properties of the coating, ʻo ia hoʻi, ke kūlana maoli e ʻike ʻia i ke kaʻina hana pipeline, e like me ka noʻonoʻo ʻana i ke kuʻi ʻana o ka pipeline ma hope o ke kuʻi ʻana a me ka hāpai ʻana i ka lalo. auwai i ke kūkulu ʻia ʻana o ka paipu lōʻihi. Hoʻonohonoho ʻia nā mea kikoʻī haʻahaʻa haʻahaʻa haʻahaʻa e like me nā diameters paipu like ʻole, ua hoʻoholo ʻia nā mea kūʻē i ka hopena o ka uhi ʻia e ka pōʻino o ka hui ʻana i hoʻokumu ʻia e ka lawe ʻana i ka pipeline a me ka hoʻihoʻi ʻana, ʻo ke kūʻē ʻana a me ke kūʻē ʻana o nā uhi i hoʻoholo ʻia e nā ʻōpala a nā abrasions i ka wā e hele ai nā paipu. Wear resistance, etc. Mai ka hiʻohiʻona o kēia mau waiwai, ʻaʻohe mea epoxy powder coating, ʻekolu-layer structure or polyurea coating, loaʻa iā lākou nā hana maikaʻi a pau, akā ma ke ʻano o ka mānoanoa o ka uhi ʻana, ʻekolu-layer polyethylene ka mea kiʻekiʻe loa o ka hopena kūʻē kūʻē. oiai e pulupulu ana He mea maikai loa no hoi ka nui o ke ku'e hopena o 14.7J no ka uhi pale polyurea.

No ka mea, hoʻohana nui ʻia ka uhi ʻana o nā pipeline lōʻihi i ka hui pū ʻana me ka pale cathodic, ka hoʻolālā ʻana oka uhi paipuʻOi aku ka nānā ʻana o nā mea hōʻailona i ka hana anti-cathodic disbondment o ka uhi ʻana, pēlā e hoʻonohonoho ai i nā papahana anti-cathodic disbondment no ka wā pōkole a me ka manawa, e noʻonoʻo ana i ka hoʻohana ʻana i nā pipeline lōʻihi. Hoʻonohonoho ka mahana i ka papahana disbondment cathodic kiʻekiʻe. Mai ka helu helu hoʻonohonoho o ka ʻike, ʻike ʻia ʻo ka anti-cathodic disbondment index o ka epoxy coating ʻoi aku ka kiʻekiʻe, ʻo ka disbondment cathodic kiʻekiʻe he 8.5mm ma ka lumi wela no 28d, a ʻo ka disbondment cathodic kiʻekiʻe ma ke kiʻekiʻe he 6.5mm ma 48h. . ʻO nā hōʻailona o ka uhi ʻana o ka urea he ʻano wehe, 12mm a me 15m pakahi.
