不锈钢法兰波纹伸缩器按照公称压力分为0．6MPa、1．0MPa、1．6MPa、2．5MPa，公称直径范围为50mm－1400mm。供热管网设计时，先确定管道固定支架间距，然后计算管段的热伸长量，再根据样本选用合适的轴向波纹补偿器。需要注意的是，波纹补偿器样本中的各项参数是在一定基准温度和疲劳次数下计算得到的，在设计选型时，应根据实际供热介质温度和疲劳次数要求进行相应的修正。
The stainless steel flange bellows expander is divided into 0.6 MPa, 1.0 MPa, 1.6 MPa and 2.5 MPa according to the nominal pressure. The nominal diameter ranges from 50 mm to 1400 mm. In the design of heating pipe network, the spacing of fixed pipe brackets is determined firstly, then the thermal elongation of the pipe section is calculated, and then the appropriate axial corrugation compensator is selected according to the sample. It should be noted that the parameters in the sample of corrugated compensator are calculated under a certain reference temperature and fatigue number. In the design and selection, the corresponding modifications should be made according to the actual heating medium temperature and fatigue number requirements.
