無(wú)約束型補(bǔ)償器內(nèi)的波紋管采用單層、雙層或多層U型波,波紋管和導(dǎo)流套材料為1Cr18Ni9Ti等奧氏體不銹鋼,其它材料為低碳鋼或低合金鋼。無(wú)約束型補(bǔ)償器在固定支架間距的確定和固定支座推力計(jì)算等和普通的軸向型補(bǔ)償器相同。無(wú)約束膨脹節(jié)除了取消予拉伸工作外,還大大地寬松了安裝要求。無(wú)約束膨脹節(jié)可象一段短管一樣安裝于管道中,不必按其它軸向型膨脹節(jié)通常要求的全線鋼管接好后再割下和膨脹節(jié)等長(zhǎng)管道的方法。還由于無(wú)約束膨脹堅(jiān)固的外殼,也方便了運(yùn)輸,安裝和保溫。
性能特點(diǎn)
1、無(wú)約束型波紋補(bǔ)償器在固定支架間距的確定和固定支座推力計(jì)算和普通的軸向型補(bǔ)償器相同。為了使工程穩(wěn)定可靠,無(wú)約束補(bǔ)償器除要求靠近固定支架安裝外,仍要求每個(gè)固定支架間距內(nèi)設(shè)三個(gè)導(dǎo)向支架?! ?br>2、無(wú)約束補(bǔ)償器可應(yīng)用于管道的架空、地溝敷設(shè),也可應(yīng)用于有補(bǔ)償?shù)闹甭穹笤O(shè),此時(shí)無(wú)約束補(bǔ)償器處應(yīng)設(shè)檢查井或暗室。
3、無(wú)約束波紋補(bǔ)償器用于管道的軸向補(bǔ)償,補(bǔ)償量大,具有強(qiáng)力自導(dǎo)向和的抗彎能力,從而可以簡(jiǎn)化管道導(dǎo)向支架的設(shè)計(jì),使導(dǎo)向支架的間距安裝均可任意調(diào)節(jié)。
