鋼帶波紋管又叫鋼帶增強聚乙烯螺旋波紋管是一種以高密度聚乙烯(PE)為基體(內(nèi)外層)與表面涂敷粘接樹脂鋼帶復合的纏繞結(jié)構(gòu)壁管。管壁結(jié)構(gòu)由三層構(gòu)成：內(nèi)層是一個連續(xù)實壁PE內(nèi)層管，內(nèi)層管外纏繞有(用鋼板成形為“V”型的)環(huán)形波狀鋼帶增強體，在波狀鋼帶增強體外復合有聚乙烯的外層，從而復合成整體的螺旋波紋管。其典型的結(jié)構(gòu)如圖所示。鋼的彈性模量是聚乙烯的近200倍（碳素鋼的彈性模量在190000MPa左右），結(jié)合金屬和塑料的優(yōu)點顯然是達到高剛度低消耗的理想辦法，能夠?qū)摬牡母邉偠取?*度和塑料的耐腐蝕、耐磨損和柔韌性等優(yōu)良特性有機地結(jié)合起來，發(fā)揮兩方面的優(yōu)點，彌補兩方面的缺點，實現(xiàn)高性能和低成本的統(tǒng)一。 </p><p> 耐壓力是波紋管性能的一個重要參數(shù)。波紋管在常溫時，波形上不發(fā)生塑性變形所能承受的比較大靜壓力，即為波紋管的比較大耐壓力在一般情況下，波紋管是在一定的壓力（內(nèi)壓或外壓）下工作的，所以它在整個工作過程中必須承受這個壓力而不產(chǎn)生塑性變形。波紋管的耐壓力實際上屬于波紋管的強度范疇。計算的關(guān)鍵是應力分析，也就是分析波紋管管壁上的應力只要波紋管管壁上比較大應力點的應力不超過材料的屈服強度，波紋管所受的壓力就不會達到其耐壓力。廣泛應用于石化、儀表、航天、化工、電力、水泥、冶金等行業(yè)。</p><div

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)向心的應用領(lǐng)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(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(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。塑料等其他材質(zhì)波紋管在介質(zhì)輸送、電力穿線、機床、家電等領(lǐng)域有著不可替代的作用。成都日豐波紋管定制</p><p

波紋管在壓縮狀態(tài)下工作時的允許壓縮位移量比工作在拉伸狀態(tài)下的允許拉伸位移量要大一些，所以在設計波紋管時應盡可能讓波紋管在壓縮狀態(tài)下工作。通過實驗發(fā)現(xiàn)，在一般情況下，同一材料、同一規(guī)格的波紋管，其允許的壓縮位移是允許的拉伸位移的。允許位移與波紋管的幾何尺寸參數(shù)及材料性能有關(guān)。一般情況下，波紋管的允許位移大小與材料的屈服強度及外徑的平方成正比，而與材料的彈性模量、波紋管的壁厚成反比。同時，相對波深、波厚對它也有一定影響。成都日豐波紋管定制</p></p><br
