HDPE雙壁波紋管是以高密度聚乙烯為原料的新型管材。具有重量輕、耐高壓、韌性好、使用壽命長(zhǎng)的特點(diǎn)。由于連接方便可靠，在國(guó)內(nèi)外得到了很多的應(yīng)用。更換了大量的混凝土管和鑄鐵管。 </p> <p> 對(duì)管道有一定理解的朋友應(yīng)該知道，當(dāng)我們選擇需要的管道時(shí)，我們將特別注意管道的環(huán)剛度，不同值的環(huán)剛度表示管道抵抗外部壓力負(fù)載的能力。我們需要知道的是，**重要的是選擇環(huán)剛度值，這也決定了管道能否在施工過(guò)程中安全、平穩(wěn)地運(yùn)行，因此我們必須特別注意。我們知道HDPE雙壁波紋管的環(huán)剛度在室外排水工程中是非常重要的。如果它太高，就不起作用。過(guò)高會(huì)造成原料浪費(fèi)，增加成本。如果太低，管道可能會(huì)因變形而損壞。那么如何更好地把握這個(gè)度來(lái)確定其環(huán)剛度的值呢？ </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明**度雙壁波紋管廠家現(xiàn)貨"

3、當(dāng)波紋長(zhǎng)度小于或等于外徑時(shí)，計(jì)算結(jié)果非常接近實(shí)際爆破壓力;細(xì)長(zhǎng)波紋管的實(shí)際爆破壓力要低得多。爆破壓力約為允許工作壓力的3至10倍。 </p> <p> 4、波紋管的耐壓性實(shí)際上屬于波紋管的強(qiáng)度類別。計(jì)算的關(guān)鍵是應(yīng)力分析，即分析波紋管壁上的應(yīng)力。只要波紋管壁上較大應(yīng)力點(diǎn)處的應(yīng)力不超過(guò)材料的屈服強(qiáng)度，波紋管上的壓力就不會(huì)達(dá)到其承受壓力。 </p> <p> 5、耐壓性能是波紋管性能的重要參數(shù)。當(dāng)波紋管處于室溫時(shí)，塑性變形所能承受的較大的靜壓對(duì)波形，即波紋管的較大阻力壓力。一般情況下，波紋管處于一定的壓力（內(nèi)壓或外壓）。因此，在整個(gè)工作過(guò)程中，它必須在不發(fā)生塑性變形的情況下承受這種壓力。 </p><div style="width:100%;text-align:
