金屬波紋管補償器由設計、制造、安裝和運行管理等多個環節組成。因此可靠性也應該從這幾方面考慮。波紋管補償器在供熱管網選擇使用的材料,除了它的工作效率,也應考慮它的介質、工作溫度和外部環境之外,還要考慮應力腐蝕,水處理劑等。
在正常情況下,用波紋管材料應當符合下列條件:
(1)高彈性極限,抗拉強度和疲勞強度,以確保波紋管工作。
(2)良好的可塑性,以方便波紋管成型加工,并通過隨后的處理過程(加工硬化,熱處理等),以獲得足夠的硬度和強度。
(3)良好的耐腐蝕性能,以滿足波紋管的不同工作環境要求。
(4)良好的焊接性能,以滿足在焊接工藝要求下生產波紋管。對于溝敷設熱管網,當在低洼管道,雨或意外的污水浸泡波紋管補償器時,應考慮比鐵更耐腐蝕的材料,如選擇鎳合金,高鎳合金等等。
