聚乙烯具有獨(dú)特的柔韌性和優(yōu)良的耐刮痕的能力。聚乙烯管道系統(tǒng)的撓性有著巨大的技術(shù)經(jīng)濟(jì)價(jià)值。聚乙烯的撓性是一個(gè)重要的性質(zhì)，它極大的提高了該材料對(duì)于管線工程的價(jià)值。良好的撓性使聚乙烯管可以盤卷，以較長(zhǎng)的長(zhǎng)度進(jìn)行供應(yīng)，避免了大量的接頭和管件。 </p> <p> 耐低溫 </p> <p> 聚乙烯具有非常突出的耐低溫性能。pe管的低溫脆化點(diǎn)為-70℃，優(yōu)于其他管道。在冬季野外施工時(shí)聚氯乙烯(PVC-U)管容易脆裂，我國(guó)北京地區(qū)鋪設(shè)聚氯乙烯(PVC-U)埋地給水管試點(diǎn)工程中總結(jié)的一條經(jīng)驗(yàn)是溫度在零度以下就不適宜進(jìn)行聚氯乙烯(PVC-U)管的鋪設(shè)施工了。 </p>
