碳素波紋管是采用HDPE（高密度聚乙烯）與碳素復(fù)合材料擠出成型和獨特的旋轉(zhuǎn)成型工藝技術(shù)生產(chǎn)的新型電力線纜保護管道。碳素波紋管是使用較為大面積的地下電纜護套管，有著較高的性價比，綜合有以下**優(yōu)點：柔韌性好：產(chǎn)品呈螺紋狀.遇障礙物彎曲自由通過，便于施工；單根長：**短幾十米，長達幾百米；質(zhì)輕：因材料采用高密度塑料，所以質(zhì)量輕，便于搬運；強度高：因特殊的螺紋狀，很大增強了抗壓力；耐腐蝕：耐酸憾，鹽及化學(xué)物質(zhì)，使用可達50年；抗地質(zhì)沉降：地質(zhì)變化因其結(jié)構(gòu)為螺紋狀，所以抗拉伸；穿線方便：管內(nèi)預(yù)放鐵絲，便于牽拉電纜；施工費用低：以上優(yōu)點證明了費用低，接頭少，降低成本；接頭結(jié)實：使用安全，接頭少，采用**橡膠接頭，不浸水；散熱好：管體呈螺紋狀，散熱面積大。 </p><p> HDPE雙壁波紋管施工很方便，因為它重量比較輕，方便運輸和連接。相比較相同口徑的管材來說，HDPE管材的流量更大，因此，在對流量有要求的情況下，選擇口徑較小的HDPE管材就能達到要求。市政排水中，對于管材的選擇有著諸多要求，因為市政排水的水質(zhì)較差，居民生活用水、自然界的水源等大多含有腐蝕性物質(zhì)、雜質(zhì)等，因此需要排水管材具有良好的防腐蝕性能，HDPE雙壁波紋管恰好符合這一要求。同時，市政排水要求管材輸水能力較強，水流速度快，且管材不能輕易移動，HDPE波紋管也能滿足這樣的要求。因此，市政排水管材推薦HDPE波紋管。單位長度的波紋管具有質(zhì)量輕、省資料、降能耗、價格便宜等特性。</p><div

HDPE管對地面下沉或地殼變動不斷裂；HDPE管的伸長率為鋼管的20多倍，是PVC的六倍半，其斷裂伸長率卻非常高，延伸性很強。這就意味著當(dāng)?shù)孛嫦鲁粱虬l(fā)性地震時地殼有變動的情況下，HDPE管能夠產(chǎn)生抗性變形而不斷裂。這一點遠優(yōu)于鋼管，也優(yōu)于有明顯脆性的PVC管。這一性能已被國內(nèi)外的證明(日本阪神大地震未造成管斷裂;HDPE管在支南保山地震中未破壞都是證明)。HDPE管的滲透率遠低于水泥管材，低于2倍，對地下水不會造成二次污染；水泥管材無彈性，雖然配有膠圈，但密封效果差，特別是施工人員由于水泥管材重，不好施工，索性不管承插的效果，導(dǎo)致膠圈失去作用，從而使管材滲透率提高。因為雙壁波紋管的壁較薄，因而比同種質(zhì)料、平等標(biāo)準(zhǔn)的實心壁管材節(jié)省質(zhì)料30%一50%。四川日豐碳素波紋管批發(fā)</p><p
