矩形非金屬波紋補償器

該類膨脹節主要應用于矩形截面的管道、容器設備上,如風機進出口管道、鍋爐煙氣管道以及表面冷凝器上,其特點是截面大、壓力低,溫度高。是良好的系統三維熱補償元件。

因矩形截面較大,總體剛度,強度較小,須設置加強件。此外,還應加導向結構,當a、b邊長尺寸更大時,這種導向結構數量會更多,以保證膨脹節工作時活動自如,正確吸收熱位移;如果是法蘭聯接,則沿法蘭框架還須設置若干支撐件,用以支撐整個膨脹節的重量,形成一個活動框架,既提高整個膨脹節結構的剛性,穩定性和可靠性,又可減少波紋管的橫向彎曲應力和撓度。在運輸過程當中,為保證膨脹節的安全性,還須設置若干個裝運保護支架(或拉桿),當膨脹節在現場安裝完畢之后再予以拆除,保證膨脹節在工作環境下具有補償位移的能力。
