PPH管道安裝時要注意問題
1、PPH管道的選用:PPH管道(均聚聚丙烯管),其原材料經過β改性,具有均勻細膩的Beta晶型結構,具有極高的化學穩定性和耐高溫性,廣泛應用于鋼廠(酸洗、酸再生、酸霧)、煙氣脫硫、工藝冷卻水和化工行業的耐腐蝕性介質輸送。
2、施工過程的監理:由于PPH管道還處于推廣階段,施工人員對施工工藝掌握不到位,且這新型管材對施工人員技術水平要求高,施工難度較大。因此,對施工人員的崗前培訓就顯得尤為重要。監理在現場檢查中尤其要重視管道連接, PPH管道最易發生滲漏、爆管的地方就是管道連接處。PPH管道的連接方式主要有熱熔連接及法蘭連接?,F分別就注意事項簡述如下:應使用廠家提供的專用熔接工具,連 接前,應清潔管子接口位置和管件,保證其清潔、干燥、無油,在管子和管件上做出標記,熔合溫度要定期檢查,確保在正確值,熔合時應防止管件和管子向外滑 動,加熱后嚴禁轉動,嚴格遵守保持時間和冷卻時間。PPH管道試壓應嚴格按規范要求,只有這樣才能保證系統正??煽康剡\行。
