從上面三種使用實例中可見，由于使用條件不同，波紋管要求的使用壽命相差很**紋管壽命與所選用材料的疲勞特性有關(guān)，同時也取決于成形波紋管的殘余應(yīng)力的大小、應(yīng)力集中的情況和波紋管的表面質(zhì)量等。此外，使用壽命與波紋管的工作條件有關(guān)。例如：波紋管工作時的位移、壓力、溫度、工作介質(zhì)、振動條件，巴中聯(lián)塑波紋管生產(chǎn)基地、頻率范圍、沖擊條件等。波紋管在工作過程中，其壽命長短主要取決于工作過程中產(chǎn)生的比較大應(yīng)力。為了降低應(yīng)力，一般通過減少波紋管的工作位移和降低工作壓力來實現(xiàn)，巴中聯(lián)塑波紋管生產(chǎn)基地。在一般設(shè)計中規(guī)定波紋管的工作位移應(yīng)小于它的允許位移的一半，它的工作壓力應(yīng)小于波紋管的耐壓力的一半。對生產(chǎn)的波紋管進行試驗證明，巴中聯(lián)塑波紋管生產(chǎn)基地，如果波紋管按上述規(guī)范工作，它的便用壽命基本土可達到5萬次左右。
