3pe防腐螺旋鋼管廠家電話：胡經理3PE防腐(三層聚乙烯)工藝是上世紀90年代後期從國外引進的先進防腐技術，它的全稱為熔結環氧/擠塑聚乙烯結構防護層。3PEfangfujishuzonghelehuanyangtucengyujiyajuyixiliangzhongfangfucengdeyouliangxingneng，jianghuanyangtucengdejiemiantexinghenaihuaxuetexingyujiyajuxifangfucengdejixiebaohutexingdengyoudianjieheqilai，congerxianzhegaishanlegezidexingneng。qitedian:機械強度高、耐磨損、耐腐蝕、耐熱、耐冷、baiduguan可應用於150度介質中，在寒冷地帶均適應。因此，3PE防腐層是理想的埋地管線外防護層。據權威部門檢測，用3PE防腐技術的埋地管道壽命可長達50年。2PE防腐(二層聚乙烯)管道二層PE防腐結構,第一層膠粘劑（AD）,第二層聚乙烯（PE）,二種材料融為一體,各層厚度同三層PE相同.由此看出區別在於：3PE防腐多了一個環氧粉末層，而環氧粉末耐腐蝕性能好、力學性能好、抗陰極剝離強，雖然它有表麵處理嚴格、耐候性差、吸水率偏高等優點，但它適用於埋地管道海底管道，包覆層厚度僅為0.3～0.5毫米，使用壽命可達40～50年
