pe給水管的變形檢測及處理
給排水pe給水管道施工中經常出現漏水的問題多是由管道變形所致，因此pe給水管的變形檢測及處理至關重要。pe管道的變形檢查應在施工過程中進行。即對管道的壓扁率進行檢測，每一施工段初始50m不少于3次檢測，測量點管軸垂直和水平直徑的表面測量，取起點、中點，靠近終點檢測；對于允許的短期(24小時)壓扁率，高密度聚乙烯大口徑塑料管施工變形是真實的測得的短期平準率應為≯ 4%。如果pe管道在施工過程中發生變形，其短期壓扁率為4%，施工變形過大，管道施工變形按以下規定處理，其短期壓扁率當局部區域為4%時，該區域的填充可以被移除并在校正后重新填充。當管道因施工變形造成的短期壓扁率超過90%和4%時，應更換PE管道。對于不能進入管道的塑料管，應通過在圓板管中拖動來檢測變形值。pe給水管件
