PVC-U給水管是用來做給水用的，也有部分用于農(nóng)田灌溉，與排水管比較大的區(qū)別就是需要能承受壓力，如果是給水工程上還需要有衛(wèi)生指標(biāo)，無毒無污染等檢測(cè)指標(biāo)。 </p> <p> 以上就是優(yōu)管網(wǎng)小編和大家分享的關(guān)于PVC-U管材給水管和排水管兩者之見的區(qū)別介紹，如需了解更多關(guān)于PVC-U管材知識(shí)請(qǐng)關(guān)注優(yōu)管網(wǎng)。 </p> <p> PVC-U管道是以聚氯乙烯(PVC)樹脂為主要原料，PVC-U管道和傳統(tǒng)的管道相比，具有重量輕、耐腐蝕、水流阻力小、節(jié)約能源、安裝迅捷、造價(jià)低等優(yōu)點(diǎn)。我國(guó)從上個(gè)世紀(jì)80年代開始，在市政工程及建筑工程中試點(diǎn)應(yīng)用PVC-U管道，經(jīng)過10多年的推廣，PVC-U管道得到了長(zhǎng)足發(fā)展。力達(dá)配備先進(jìn)、高精度檢測(cè)設(shè)備，嚴(yán)格按標(biāo)準(zhǔn)進(jìn)行各項(xiàng)檢測(cè)出廠，做到“用力達(dá)管材，做放心工程”的理念。
