四川金屬波紋管補償器的使用條件分析
來源:發表時間:2021-08-26 17:10

  金屬波紋管補償器的設計、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幾方面考慮。選擇在波紋管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,我們也考慮到的應力腐蝕,水處理劑,清洗管道的可能性影響材料,并在此基礎上,與波紋管材料,焊接,成型,材料成本和性能,指出了材料的經濟和實際生產優化波紋管。在正常情況下,用波紋管材料應當符合下列條件:

  1)高彈性,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,以滿足波紋管的工作在不同的環境要求。

  4)良好的焊接性能,以滿足在焊接工藝要求生產過程中波紋管。對于溝敷設熱管網,當在低洼管道,雨或意外的污水將被浸泡波紋管補償器,應考慮如鐵更耐腐蝕的材料,選擇鎳合金,高鎳合金等等。由于這種材料報價上漲的波紋管制造,我們可以考慮一個額外的腐蝕層表面耐磨合金只在接觸腐蝕介質。

  波紋管疲勞壽命的類型和失敗的原因分析設計的補償可以看到,波紋管的穩定性,穩定和腐蝕周兩對位移量是壽命。過低會導致下的穩定性和抗腐蝕金屬波紋管疲勞壽命。
