傳統(tǒng)的波紋管以金屬材質(zhì)為主，近些年波紋管廠家的產(chǎn)品以塑料材質(zhì)為主，金屬材質(zhì)波紋管主要用于電力，冶金，石化和集中供暖等行業(yè)管網(wǎng)系統(tǒng)中，作為柔性連接和熱補(bǔ)償構(gòu)件，也可以做成熱系統(tǒng)中的熱交換器，傳統(tǒng)的波紋管類彈性元件已經(jīng)向心的應(yīng)用領(lǐng)域擴(kuò)展，這也成為波紋管類組件的發(fā)展趨勢，金屬波紋管補(bǔ)償器的設(shè)計，制造，安裝和運(yùn)行管理等多個環(huán)節(jié)組成，因此可靠性也應(yīng)該從這幾個方面考慮，選擇波紋管在供熱管網(wǎng)選擇使用的材料，除了它的工作效率以外，也應(yīng)該考慮它的介質(zhì)，工作溫度和外部的環(huán)境，金屬波紋管要考慮到腐蝕性的問題。雙臂波紋管是波紋管廠家目前主要的產(chǎn)品之一，屬于新型的管材，具有重量輕，強(qiáng)度高，施工方便，用料省的優(yōu)點(diǎn)，和同等強(qiáng)度的光壁管相比較可以節(jié)省原料的百分之40左右，廣泛應(yīng)用在通信光電纜護(hù)套，建筑排水，市政排水，農(nóng)田低壓灌溉等領(lǐng)域，雙臂波紋管近些年在各個領(lǐng)域都有涉及到，在通訊電纜護(hù)套管領(lǐng)域已經(jīng)基本取代水泥管，和其他塑料管相比其用量也比較大，在建筑排水領(lǐng)域，因為其隔音性能比較差，同時管配件開發(fā)不夠，所以用量不是很多，但子啊市政排水和工廠排污方面特別的實用。

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、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)。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(jìn)行試驗證明，如果波紋管按上述規(guī)范工作，它的便用壽命基本土可達(dá)到5萬次左右。
