構(gòu)造：HDPE雙壁波紋管是由HDPE同時(shí)擠出的波紋外壁和一層光滑內(nèi)壁一次熔結(jié)擠壓成型，管壁截面為雙層結(jié)構(gòu)，其內(nèi)壁光滑平整，外壁為等矩排列的具有梯形中空結(jié)構(gòu)的管材。 </p> <p> <br /> </p> <p> 連接：主要采用橡膠圈承插連接（也可采用熱縮帶連接）。 </p> <p> <br /> </p> <p> 優(yōu)點(diǎn)：具有較好的環(huán)剛度和強(qiáng)度、韌性；重量輕、耐沖擊性強(qiáng)、不易破損，且運(yùn)輸安裝方便。由于雙壁波紋管特殊的管壁結(jié)構(gòu)設(shè)計(jì)，使得該管在同樣直徑和達(dá)到同樣環(huán)剛度的條件下，用料（HDPE）**省。 </p><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(dòng)；水套與在型模塊的中線偏離（成型機(jī)與水套不對(duì)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(huì)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(gè)波和第二個(gè)波內(nèi)的氣壓過?。粩U(kuò)口后的個(gè)波和第二個(gè)波所對(duì)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(dòng)過晚；原材料的韌性差等。 </p><div style="width:100%;text-align:
