高密度聚乙烯(HDPE)具有優(yōu)異的化學(xué)穩(wěn)定性、耐老化及耐環(huán)境應(yīng)力開裂的性能。由其為原材料生產(chǎn)出來的HDPE雙壁波紋管屬于柔性管。其要性能如下： </p> <p> <br /> </p> <p> 抗外壓能力強(qiáng)： </p> <p> <br /> </p> <p> 外壁呈環(huán)形波紋狀結(jié)構(gòu)，增強(qiáng)了管材的環(huán)剛度，余姚HDPE雙壁波紋管批發(fā)廠，從而增強(qiáng)了管道對土壤負(fù)荷的抵抗力，在這個性能方面，HDP巨雙壁波紋管與其他管材相比較具有明顯的優(yōu)勢，余姚HDPE雙壁波紋管批發(fā)廠。 </p> <p> <br /> </p> <p> 工程造價低： </p> <p> <br /> </p> <p> 在等負(fù)荷的條件下，HDPE雙壁波紋管只需要較薄的管壁就可以滿足要求。因此，與同材質(zhì)規(guī)格的實(shí)壁相管比，能節(jié)約一半左右的原材料，所以HDPE雙壁波紋管造價也較低。這是該管材的又一個很突出的特點(diǎn)。 </p> <p> <br /> </p> <p> 施工方便： </p> <p> <br /> </p> <p> 由于HDPE雙壁波紋管重量輕，余姚HDPE雙壁波紋管批發(fā)廠，搬運(yùn)和連接都很方便，所以施工快捷、維護(hù)工作簡單。在工期緊和施工 </p> <p> <br /> </p> <p> 條件差的情況況下，其優(yōu)勢更加明顯。 </p> <span style="display:none;"></span><div style="width:100%;text-align:

擴(kuò)口不良。擴(kuò)口不良可分為以下幾種狀況： </p> <p> <br /> </p> <p> d、擴(kuò)口前端的內(nèi)層有凹限引起這種現(xiàn)象的原因一般是內(nèi)層沖氣過早啟動；水套與在型模塊的中線偏離（成型機(jī)與水套不對中）；內(nèi)層壁厚偏薄；內(nèi)層真空過早停止。 </p> <p> <br /> </p> <p> e、擴(kuò)口末端內(nèi)層堆料，這種現(xiàn)象往往會導(dǎo)致擴(kuò)口往里面凹。其原因是擴(kuò)口末端內(nèi)層料過厚；成型機(jī)在此段的降速的量過大；之前幾段的內(nèi)層沖氣過大；內(nèi)層的料溫過高致料坯過軟；外層的料坯在此段過厚。 </p> <p> <br /> </p> <p> f、擴(kuò)口末端的內(nèi)層有凹限其原因一般是擴(kuò)口后的個波和第二個波內(nèi)的氣壓過??；擴(kuò)口后的個波和第二個波所對應(yīng)的內(nèi)層壁厚過厚；內(nèi)層真空度較小或內(nèi)層真空啟動過晚；原材料的韌性差等。 </p><div style="width:100%;text-align: center;"><img

高密度聚乙烯(HDPE)雙壁波紋管，是一種具有環(huán)狀結(jié)構(gòu)外壁和平滑內(nèi)壁的新型管材，80年代初在德國首先研制成功。管壁截面為雙層結(jié)構(gòu)，其內(nèi)壁光滑平整，外壁等距排列的具有梯形中空結(jié)構(gòu)的管材。公稱直徑（DN）：管材的公稱直徑，分內(nèi)徑系列和外徑系列兩類同時執(zhí)行。環(huán)向彎曲剛度：管道抵抗環(huán)向變形能力的量度，單位KN/㎡。經(jīng)過十多年的發(fā)展和完善，已經(jīng)由單一的品種發(fā)展到完整的產(chǎn)品系列。目前在生產(chǎn)工藝和使用技術(shù)上已經(jīng)十分成熟。由于其優(yōu)異的性能和相對經(jīng)濟(jì)的造價，在歐美等發(fā)達(dá)國家已經(jīng)得到了極大的推廣和應(yīng)用。在我國，HDPE雙壁波紋管的推廣和應(yīng)用正處在上升勢態(tài)階段，各項(xiàng)技術(shù)指標(biāo)均達(dá)到使用標(biāo)準(zhǔn)。
