class="title">詳細(xì)說明</p><div id="kewyahw" class="box"><p><p> 聚氨酯保溫管在安裝時是有嚴(yán)格的技術(shù)規(guī)范要求的，必須要參照相應(yīng)設(shè)計技術(shù)規(guī)范執(zhí)行。 </p> <p> 保溫管的安裝要求：首先按照設(shè)計圖紙的要求，驗收管段質(zhì)量，仔細(xì)核對設(shè)計材料和各部位的幾何尺寸，充分考慮管段預(yù)留的位置和管道的吊裝措施，熱力管道上放空和放凈開孔均應(yīng)在地面時完成，管線在吊裝之前應(yīng)完成管道管托的焊接工作并完成管道及管托的油漆工作，廣西ppr聚氨酯保溫管標(biāo)準(zhǔn)，管段預(yù)留焊口位置不刷油漆，廣西ppr聚氨酯保溫管標(biāo)準(zhǔn)，廣西ppr聚氨酯保溫管標(biāo)準(zhǔn)，吊管和布道安裝順序進行，先安裝彎頭，后進行直管安裝，待直管固定管托安裝完畢再進行與彎管接口工作。

聚氨酯保溫管高的耐溫性能等級在140℃左右,50℃時導(dǎo)熱系數(shù)低于0.033,吸水率低于10%,閉孔率高達88%。髙質(zhì)量的聚氨酯保溫管外護層髙密度聚乙烯外套表面不應(yīng)有溝槽、裂紋、氣泡、雜質(zhì)、凹陷、顏色不均勻等情況,拉伸屈服強度大于19MPa,斷裂伸長率大于350%,具有良好保溫,防水防腐囯強度高不怕植物根刺等優(yōu)點,該產(chǎn)品主要應(yīng)用于城鎮(zhèn)集中倛熱管網(wǎng),熱油輸送管線、廠區(qū)工業(yè)管道、室內(nèi)外熱力管網(wǎng)、高寒地區(qū)輸水管線等,還能滿足城鎮(zhèn)集中供冷領(lǐng)域的要求。該產(chǎn)品一般適用于輸送介質(zhì)溫度不高于140℃,壓力小于1.6MPa的流體輸送管道,正確的安裝和維護網(wǎng)管使用壽命可長達30年。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣西ppr聚氨酯保溫管標(biāo)準(zhǔn)"

聚氨酯保溫管不僅需要在生產(chǎn)時注意，還需在運輸和貯存上把控細(xì)節(jié)，只有將聚氨酯保溫管保存完好，在使用的時候才不會出現(xiàn)質(zhì)量問題。保溫管堆放高度不應(yīng)大于2M，保溫管不得暴曬、雨淋和浸泡，不宜長時間露天存放，宜用篷布遮蓋。地面平整、無碎石等堅硬雜物；堆放場地應(yīng)挖溝排水，場地內(nèi)不允許積水；保溫管的工作管兩端面應(yīng)始終保證管端及接頭處的密封防水。管道搬運應(yīng)使用吊車，不能使用叉車，保溫管必須采用吊裝帶等不損傷外護管層和防腐層的方法吊裝。在裝卸過程中嚴(yán)禁碰撞、拋摔和在地面上拖拉滾動，才能使其使用壽命延長。萬里管道采用合理化倉儲，保溫管存放合理，擺放有序，使用時質(zhì)量可靠放心。
