ʻO ke ʻano o ka mālama anti-corrosion o ka paipu hao ductile

Ke ano o ka anti-corrosion lapaau opaipu hao ductile:

1. ʻO ka pipeline o ka asphalt coating e lawe i ke kinoea.ʻO ka hoʻomaʻamaʻa mua ʻana i ka paipu ma mua o ka pena e hiki ke hoʻomaikaʻi i ka hoʻopili ʻana o ka pena asphalt a wikiwiki i ka maloʻo.2. ʻO ka lining mortar sima + He kūpono kēia ana anti-corrosion i loko no nā paipu wai wai, hiki ke hoʻomaikaʻi i ka pale ʻana o ka pale.3. ʻAʻole kūpono wale ka epoxy coal tar tar coating no nā pipeline gas, akā no nā pipeline sege.ʻO ia ka uhi ʻelua ʻāpana me ke kiʻekiʻe adhesion a me ka maʻalahi hiʻohiʻona 4. He kūpono ka epoxy ceramic lining no nā pipelines wai a me nā pipeline gas, akā ma muli o ke kaʻina hana paʻakikī a me ke kumukūʻai kiʻekiʻe, aia kekahi mau palena i ka noi.ʻO ka epoxy ceramic lining he kiʻekiʻe adhesion a me ka hoʻopau kiʻekiʻe, a he uhi anti-corrosion maikaʻi loa.5. ʻO ka pena kima alumina a i ʻole ka peʻa sima sulfate he kūpono ia no ka anticorrosion kūloko o nā paipu hao ductile o nā paipu wai, e hoʻomaikaʻi ai i ka pale ʻana o ka ʻakika a me nā mea alkali i loko o ka wai.6. He hopena maikaʻi loa ka uhi polyurethane i ka hopena anti-corrosion.
