復合防腐(fu)管(guan)材可(ke)(ke)適(shi)用(yong)于各種(zhong)(zhong)(zhong)惡劣的環境。例如在(zai)某些(xie)沿海地(di)區，由于土(tu)壤中(zhong)含腐(fu)蝕(shi)性物質如果使(shi)(shi)用(yong)混凝土(tu)管(guan)工(gong)作壽(shou)命會很短，很希望(wang)能(neng)夠使(shi)(shi)用(yong)抗腐(fu)蝕(shi)的塑料(liao)埋地(di)排水管(guan)。中(zhong)空壁(bi)纏繞(rao)管(guan)是(shi)是(shi)一(yi)種(zhong)(zhong)(zhong)以高(gao)密度聚乙(yi)烯(HDPE)為原料(liao)，經纏繞(rao)焊接成(cheng)(cheng)型的一(yi)種(zhong)(zhong)(zhong)管(guan)材，由于其的成(cheng)(cheng)型工(gong)藝，可(ke)(ke)以生產直徑(jing)達3米(mi)的管(guan)材，這是(shi)其他生產工(gong)藝難(nan)以完成(cheng)(cheng)的。HDPE雙壁(bi)纏繞(rao)管(guan)性能(neng)特點(dian)：耐腐(fu)蝕(shi)，使(shi)(shi)用(yong)壽(shou)命超過(guo)50年(nian)。高(gao)密度聚乙(yi)烯（PE）管(guan)道使(shi)(shi)用(yong)壽(shou)命可(ke)(ke)長(chang)達五(wu)十年(nian)。鋼帶纏繞(rao)管(guan)特點(dian)：耐壓、抗沖擊。

鋼帶纏(chan)繞管(guan)(guan)(guan)節省(sheng)材(cai)料成本。與(yu)其它相(xiang)同直徑和環剛度(du)的(de)塑料管(guan)(guan)(guan)相(xiang)比鋼帶增強聚乙(yi)烯（PE）螺旋(xuan)波(bo)紋管(guan)(guan)(guan)可節省(sheng)近一半(ban)的(de)材(cai)料耗費(fei)。HDPE雙壁纏(chan)繞管(guan)(guan)(guan)性(xing)(xing)能特(te)點(dian)：耐(nai)腐蝕，使(shi)用(yong)壽命(ming)超(chao)過50年(nian)。高密(mi)度(du)聚乙(yi)烯（PE）管(guan)(guan)(guan)道使(shi)用(yong)壽命(ming)可長達五十(shi)年(nian)。鋼帶纏(chan)繞管(guan)(guan)(guan)特(te)點(dian)：耐(nai)壓、抗沖擊(ji)。HDPE雙壁纏(chan)繞管(guan)(guan)(guan)性(xing)(xing)能特(te)點(dian)：柔性(xing)(xing)或無(wu)泄漏（電熔焊(han)、對(dui)焊(han)）連接(jie)，HDPE中空壁纏(chan)繞管(guan)(guan)(guan)價格，密(mi)封性(xing)(xing)能及環保性(xing)(xing)能好兩種密(mi)封連接(jie)方式均可以簡單工具手工操作，無(wu)需機械，十(shi)分簡便快捷(jie)，達到可靠無(wu)泄露。

鋼(gang)帶(dai)纏繞(rao)管(guan)(guan)顧名思義，是在(zai)塑(su)料(liao)管(guan)(guan)加上鋼(gang)帶(dai)。埋地(di)排(pai)水用(yong)鋼(gang)帶(dai)增強螺旋波紋管(guan)(guan)以高密度聚(ju)乙(yi)烯(xi)(PE)為基體，用(yong)表(biao)面涂敷(fu)粘接樹(shu)脂的鋼(gang)帶(dai)成型為波形作為主要支撐結(jie)構，并與聚(ju)乙(yi)烯(xi)材料(liao)纏繞(rao)復合成整體的雙壁(bi)螺旋波紋管(guan)(guan)。所用(yong)材料(liao)包(bao)括(kuo)聚(ju)乙(yi)烯(xi)、鋼(gang)帶(dai)、黏結(jie)樹(shu)脂。HDPE雙壁(bi)纏繞(rao)管(guan)(guan)性能特點：內(nei)壁(bi)光滑，流動阻力比水泥(ni)管(guan)(guan)低20～30%聚(ju)乙(yi)烯(xi)（PE）管(guan)(guan)道(dao)內(nei)壁(bi)光滑，摩擦系數(shu)小，且沉(chen)淀(dian)物在(zai)管(guan)(guan)道(dao)中不(bu)易(yi)產生(sheng)聚(ju)集，長期使用(yong)后摩阻幾乎不(bu)變。鋼(gang)帶(dai)纏繞(rao)管(guan)(guan)使用(yong)范圍：市政工(gong)(gong)(gong)程(cheng)(cheng)排(pai)水、排(pai)污工(gong)(gong)(gong)程(cheng)(cheng)。工(gong)(gong)(gong)農業(ye)各(ge)種輸水、灌溉工(gong)(gong)(gong)程(cheng)(cheng)。道(dao)路公用(yong)工(gong)(gong)(gong)程(cheng)(cheng)，如鐵(tie)路、高速公路、球場等。
