YGFB型矩（方）型单波补偿器：
单波补偿器它是以波纹管为核心的扰性元件，在管线上可作轴向、横向和角向三个方向的补偿。轴向象补偿器为了减少介质的自激现象，在产品内部设有内套管，在很大程度上限制了径向补偿能力，故一般仅用以吸收或补偿管道的轴向位移（如果管系中确需少量的径向位移，也可以吸收轴向、角向和任意三个方向位移的组合；铰链补偿器（也称角向补偿器），它以两个或三个补偿器配套使用（单个使用铰链补偿器没有补偿能力），用以吸收单平面内的横向变形；万向铰链（角向）补偿器，由两个或三个配套使用，可吸收三维方向的变形量。
波纹补偿器属于一种补偿元件。利用其工作主体波纹管的有效伸缩变形，以吸收管线、导管、容器等由热胀冷缩等原因而产生的尺寸变化，或补偿管线、导管、容器等的轴向、横向和角向位移。也可用于降噪减振。在现代工业中用途广泛。
圆形、矩形、波形补偿器(膨胀节)是根据美国CE公司引进技术研制的，是一种在工作中能自由伸缩的弹性补偿原件，它结构紧凑，工作可靠，成本低廉，适用性强，有防振、防尘、防失调等功能，主要用于电站锅炉风烟系统中，也适用于冶金化工等其它类似的烟连接管道。设计时可根据不同要求制成主要吸收单向热位移得单件膨胀节，也可用于两个膨胀节组成用以吸收空间三向热位移，而不造成管道的破坏汇潜心，是保证管道安全可靠运行的必不可缺少的重要原件。
电厂烟风煤管道波纹补偿器（圆形单波补偿器）用于输送气体或含尘气体，使用压力从真空~0.1Mpa，使用温度从-40oC~420oC,任意矩形、圆形截面的烟气，通风和鼓风机管道，作补偿位移减振用。波纹补偿器按型式分，有Dg200—3600单波、双波和三波的圆形补偿器各23种规格：有Dg400—1400圆形单波密封式补偿器12种规格：有300x400—6000x5000单波、双波和三波矩形补偿器各98种规格。
