傳統(tǒng)的波紋管以金屬材質為主，近些年波紋管廠家的產(chǎn)品以塑料材質為主，金屬材質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償構件，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)向心的應用領域擴展，這也成為波紋管類組件的發(fā)展趨勢，金屬波紋管補償器的設計，制造，安裝和運行管理等多個環(huán)節(jié)組成，因此可靠性也應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，也應該考慮它的介質，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，強度高，施工方便，用料省的優(yōu)點，和同等強度的光壁管相比較可以節(jié)省原料的百分之40左右，廣泛應用在通信光電纜護套，建筑排水，市政排水，農田低壓灌溉等領域，雙臂波紋管近些年在各個領域都有涉及到，在通訊電纜護套管領域已經(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。成都康泰塑膠波紋管批發(fā)價格不能抗彎的薄殼有時稱為薄膜，忽略彎曲而算得的應力則稱為薄膜應力。</p><div

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，同時也取決于成形波紋管的殘余應力的大小、應力集中的情況和波紋管的表面質量等。此外，使用壽命與波紋管的工作條件有關。例如：波紋管工作時的位移、壓力、溫度、工作介質、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)生的比較大應力。為了降低應力，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)。在一般設計中規(guī)定波紋管的工作位移應小于它的允許位移的一半，它的工作壓力應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，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。 </p><p> 使金屬波紋管或其它彈性元件產(chǎn)生單位位移所需要的載荷值稱為元件的剛度，一般用“K”表示。如果元件的彈性特性是非線性的，則剛度不再是常數(shù)，而是隨著載荷的增大發(fā)生變化。一般工程用的波紋管類彈性元件，剛度允差可限定在+/-50%之內。波紋管的剛度按照載荷及位移性質不同，分為軸向剛度、彎曲剛度、扭轉剛度等。在波紋管的應用中，絕大多數(shù)的受力情況是軸向載荷，位移方式為線位移。以下是幾種主要的波紋管軸向剛度設計計算方法：1．能量法計算波紋管剛度；2．經(jīng)驗公式計算波紋管剛度；3．數(shù)值法計算波紋管剛度；4．EJMA標準的剛度計算方法；5．日本TOYO計算剛度方法；6．美國KELLOGG（新法）計算剛度方法；將壓力轉換成位移或力。波紋管管壁較薄，靈敏度較高，測量范圍為數(shù)十帕至數(shù)十兆帕。</p><div

彈性元件下作時有兩種狀態(tài)；一種是在一定的載荷和位移情況下工作，并保持載荷、位移始終不變或很少變化，稱為靜態(tài)工作；另一種使用情況是載荷和位移不斷周期往復交替變化．元件處于循環(huán)工作狀態(tài)。由于工作狀態(tài)的不同，元件損壞或失效的模式也不同。儀表彈性敏感元件工作在彈性范圍內，基本上處于靜態(tài)工作狀態(tài)，使用壽命很長，一般達到數(shù)萬次到數(shù)十萬次。工程中應用的波紋管類組件，有時工作在彈塑性范圍或交變應力狀態(tài)，壽命只有成百上干次。元件在循環(huán)工作時必須給定許用工作壽命，規(guī)定循環(huán)次數(shù)、時間和頻率。有時也用作為兩個零件的彈性聯(lián)接接頭等。成都康泰塑膠波紋管批發(fā)價格</p><p
