1、PP-R管較金屬管硬度低、剛性差，在搬運、施工中應(yīng)加以保護(hù)，避免不適當(dāng)外力造成機械損傷。在暗敷后要標(biāo)出管道位置，以免二次裝修破壞管道。 </p> <p> 2、PP-R管5℃以下存在一定低溫脆性，冬季施工要當(dāng)心，切管時要用鋒利刀緩慢切割。對已安裝的管道不能重壓、敲擊，必要時對易受外力部位覆蓋保護(hù)物。 </p> <p> 3、PP-R管長期受紫外線照射易老化降解，安裝在戶外或陽光直射處必須包扎深色防護(hù)層。 </p> <p> 4、PP-R管除了與金屬管或用水器連接使用帶螺紋嵌件或法蘭等機械連接方式外，其余均應(yīng)采用熱熔連接，使管道一體化，無滲漏點。 </p> <p> 5、PP-R管的線膨脹系數(shù)較大(0.15mm/m℃)，在明裝或非直埋暗敷布管時必須采取防止管道膨脹變形的技術(shù)措施。 </p> <p> 6、管道安裝后在封管(直埋)及覆蓋裝飾層(非直埋暗敷)前必須試壓。冷水管試壓壓力為系統(tǒng)工作壓力的1.5倍，但不得小于1MPa；熱水管試驗壓力為工作壓力的2倍，但不得小于1.5MPa。試壓時間與方法技術(shù)規(guī)程規(guī)定。 </p> <p> 7、PP-R管明敷或非直埋暗敷布管時，必須按規(guī)定安裝支、吊架。 </p><div

ppr管材的選用定要選擇一定要用同一廠家的產(chǎn)品，不同廠家的產(chǎn)品所含成分的比例不同。會造成粘接不牢或更本粘接不上。給水管道系統(tǒng)在驗收前，應(yīng)進(jìn)行通水沖洗。沖洗水流速宜大于2m/s，沖洗時，不應(yīng)留死角，每個配水點**應(yīng)打開，系統(tǒng)低至點應(yīng)設(shè)放水口，ppr管材廠建議的清洗時間控制在沖洗出口處排水的水質(zhì)與進(jìn)水相當(dāng)為止。生活飲用水系統(tǒng)經(jīng)沖洗后，還應(yīng)用20—30mg/l的游離氯的水灌滿管道進(jìn)行消毒。含氯水在管中應(yīng)滯留24h以上。管道消毒后，再用飲用水沖洗，并經(jīng)衛(wèi)生管理部門取樣檢驗，水質(zhì)符合現(xiàn)行的國家標(biāo)準(zhǔn)后，方可交付使用。
