二、金属波纹膨胀节优点：
 
1、补偿热膨胀：可以补偿多方向，大大  只能单式补偿的金属补偿器。    
 
2、补偿安装误差：由于管道连接过程中，系统误差再所难免，纤维补偿器较好的补偿了安装误差。    
 
3、消声减振：纤维织物、保温棉体本身具有吸声、隔震动传递的功能，能有效的减少锅炉、风机等系统的噪声和震动。  
 
4、无反推力：由于主体材料为纤维织物，无力的传递。用纤维补偿器可简化设计，避免使用大的支座，节省大量的材料和劳动力。  
 
5、良好的耐高温、耐腐蚀性：选用的氟塑料、有机硅材料具有较好的耐高温和耐腐蚀性能。    
 
6、密封性能好：有比较完善的生产装配系统，纤维补偿器可保证无泄露。    
 
7、体轻、结构简单、安装维修方便。  
 
8、价格低、质量优。
 
The advantages of metal corrugated expansion joint:
 
1, the compensation can compensate the thermal expansion: multi direction, metal compensator is much better than that of only single compensation.
 
2, compensation for installation error: as the system error is unavoidable in the process of pipeline connection, the fiber compensator is better compensated for the installation error.
 
3, noise reduction and vibration reduction:.
 
4, no reverse thrust: because the main material is fiber fabric,, avoid the use of large support, and save a lot of material and labor.
 
5, good high temperature resistance, corrosion resistance: the selected fluoroplastics, organosilicon materials have good resistance to high temperature and corrosion resistance.
 
6, good sealing performance: a better production and assembly system, fiber compensator can guarantee no leakage.
 
7, light body, simple structure, convenient installation and maintenance.
 
8, the price is low, the quality is excellent.

四、金属波纹膨胀节的安装方法及注意事项：
 
1、安装前，应先检查波纹不锈钢波纹补偿器的型号、规格及管道和支座配置必须符合设计要求。
 
2、带导流筒的补偿器，应注意使导流筒方向与介质流动方向*致（按补偿器的流向标志安装）。平面角向型补偿器的铰链转动平面应与    位移平面*致。
 
3、需要进行冷紧的补偿器，其预变形作用的辅助构件，应在不锈钢波纹补偿器预变形后拆除。
 
4、管系安装完毕后应立即拆除补偿器上用作安装运输保护的辅助定位构件及紧固件，并按设计要求将限位装置调到规定的位置。使管系    在环境条件下得以充分的补偿。
 
5、须注意的是，补偿器是不吸收扭矩的，因此在安装不锈钢波纹补偿器时不允许补偿器受到扭转。
 
6、除设计要求预拉或“冷紧”的变形外，严.使用波纹管变形的方法来调整安装管道的偏差，以免影响补偿器的正常功能，否则会降低    其使用寿命和增加管系、设备及支撑构件的载荷。
 
7、管道对中性要好，在无其它方法保证时，可采用直管辅设后切下等长管道再安装补偿器的方法来保证。
 
8、保温层应做在补偿器外保护套上，不得直接做在波纹管上。不得采用含氯的保温材料。
 
9、 安装过程中不允许焊渣飞溅到波纹管表面,使波纹受到其它机械损.。
 
10、支架必须符合设计要求，严.在支架未安装好之前在管线内试压，以免将补偿器拉坏。
 
11、不锈钢波纹补偿器所有的活动元件不得被外部构件卡.或限制其活动部位正常动作。
 
The installation method of the metal corrugated expansion joint and the matters needing attention:
 
, the model, specification, pipe and support configuration of corrugated stainless steel ripple compensator must be checked in accordance with the design requirements.
 
(according to the flow sign of the compensator). The plane of the hinge of a plane angle compensator should be in accordance with the plane of the displacement.
 
, and the auxiliary component of its pre deformation should be dismantled after the stainless steel ripple compensator is preformed.
 
4, when the piping system is installed, the compensator should be removed immediately as an auxiliary positioning member and fastener for installation and transportation protection,.
 
5, it must be noted that the compensator does not absorb the torque, so the compensator is not allowed to be torsional when the stainless steel ripple compensator is installed.
 
6, in addition to the design requirements for pre drawing or "cold tight" deformation, it is strictly prohibited to use the method of bellows deformation to adjust the deviation of the installation pipeline, so as not to affect the normal function of the compensator, otherwise it will reduce its and increase the load of piping, equipment and supporting components.
 
7,, the method of installing the equal length pipe and reinstalling the compensator can be ensured.
 
8, the insulation layer should be done on the outer protective sleeve of the compensator,.
 
9, it is not allowed to splash the slag to the surface of the bellows during the installation process, so that the ripples are damaged by other mechanical damage.
 
10, the support must comply with the design requirements, strictly prohibit the pressure test in the pipeline before the support is not installed, so as to prevent the compensator from pulling out.
