底層為熔結環氧（≥80μm），中間層為膠粘劑（170-250μm），麵層為擠塑聚乙烯（約2mm）。防護層總厚度約1.8-3.7mm。在三層結構中，熔結環氧粉末塗層的主要作用是：形成連續的塗膜，與鋼管表麵直接粘結，具有很好的耐化學腐蝕性和抗陰極剝離性能；yuzhongjiancengjiaozhanjidehuoxingjituanfanyingxingchenghuaxuezhanjie，baozhengzhengtifangfucengzaijiaogaowenduxiajuyoulianghaodezhanjiexing。zhongjiancengtongchangweigongjuwuzhanjieji，qizhuyaochengfenshijuxiting，muqianguangfancaiyongdeshiyixijigongjuwujiaozhanji。gongjuwujiaozhanjidejixingbufenguannengtuanyurongjiehuanyangfenmotucengdehuanyangjituankeyifanyingshengchengqingjianhuohuaxuejian，shizhongjiancengyudicengxingchenglianghaodezhanjie；erfeijixingdeyixibufenyumiancengjuyixijuyouhenhaodeqinhezuoyong，suoyizhongjiancengyumiancengyejuyouhenhaodezhanjiexingneng。juyiximiancengdezhuyaozuoyongshiqijixiebaohuyufangfuzuoyong，yuchuantongdeercengjiegoujuyixifangfucengjuyoutongyangdezuoyong。
