波形膨胀节展开下料尺寸计算与成形方法探讨

Discussion of Baiting Size Calculation and Forming Methods on Bellows Expansion Joint

波形膨胀节是换热器中最常见的结构,波形膨胀节它是一种挠性元件,当受到较小的轴向力时,即可有较大的变形,因此,常常用来补偿管束和筒体间的温差应力。由于它具有工作可靠、性能良好、结构紧凑等优点,广泛应用于石油化工、冶金等行业。

The bellows expansion joint is the most common structure of heat exchanger, which was a flexible element and can have a large deformation when subjected to weak axial force. Therefore, it was often used to compensate temperature stress between the bundle and the cylinder, it was widely used in petrochemical, metallurgy and other industries because of its reliable operation, good property and compact structure, etc.
