HDPE雙壁纏繞管是一種以高密度聚乙烯為原料，經(jīng)高溫高壓纏繞焊接成型的管材，通過特殊的方管纏繞成類似彈簧的結(jié)構(gòu)，并通過相同材質(zhì)改性的高溫焊條在高壓下熔焊接成管材。管材具有彈簧的可扭曲、可壓縮、可拉伸、但不可壓扁的特點(diǎn)，這一點(diǎn)對于基本無內(nèi)壓，外壓比較大的市政管材來講非常重要。因?yàn)檫@種結(jié)構(gòu)為管材提供了非常優(yōu)異的抗外壓能力。焊接方管的焊條與方管形成了個“工”字鋼形的加強(qiáng)結(jié)構(gòu)，這個結(jié)構(gòu)又被內(nèi)外雙層壁所束縛，其位置相對穩(wěn)定，管材在外壓作用時結(jié)構(gòu)穩(wěn)定，大幅度提高的管材的耐外負(fù)荷能力，螺旋中空的結(jié)構(gòu)壁管材抗外壓提高的同時產(chǎn)品的重量降低。由于其獨(dú)特的成型工藝，可生產(chǎn)口徑答DN3000mm的大口徑管材。 </p><p> 產(chǎn)品性能 </p> <p> 1、水力條件好：由于HDPE管內(nèi)壁表面光滑，管道的粗糙系數(shù)n=0.009，按曼寧公式計(jì)算流量時，同等管徑條件下，比鋼筋砼管道過流量大30%，即在輸送相同流量的污水量時，選HDPE管，其管道管徑可比選用鋼筋砼管縮小1-2個管道等級。 </p> <p> 2、密封性好，可實(shí)現(xiàn)零滲漏：由于管道連接可采用電熔焊接技術(shù)，使接口處的兩端管完全熔為一體，保證了接口不會滲漏。 </p> <p> 3、生產(chǎn)的管徑范圍廣：HDPE管目前可生產(chǎn)的管徑范圍為DN300-DN4000，比PVC管生產(chǎn)的管徑范圍增加。 </p> <p> <br />

使用壽命長：材料老化壽命在112年以上，管材設(shè)計(jì)壽命50年； </p> <p> 抗沖擊能力強(qiáng)：冰點(diǎn)以下依然具有很好的沖擊性能，不會因水結(jié)凍而凍破，優(yōu)于UPVC、玻璃鋼夾砂等材料管材； </p> <p> 重量輕：密度不足1，比水輕，*為同等規(guī)格砼管的1/8，裝卸、運(yùn)輸、安裝方便，不需大型吊裝、運(yùn)輸設(shè)備； </p> <p> 水阻系數(shù)低：n=0.0078-0.009，一般設(shè)計(jì)取0.01，而砼管 n=0.013-0.014，同口徑管材相比可增加30%-40%的流量和流速； </p> <p> <br />
