            无约束波纹补偿器

            型 号:DN
            价 格:0元
             本厂生产的膨胀节严格执行国家标准GB/T12777-2008《金属波纹管膨胀节通用技术条件》的生产工艺流程进行生产。电话:0371-64011955  0371-64030066  0371-64011900传真:0371-64011655  0371-64032361  0371-64011800
             详细介绍
            说明
               无约束型膨胀节在固定支架间距的确定和固定支座推力计算和?#32960;?#30340;轴向型补偿器完全相同。为了使工程稳定可靠,无约束型膨胀节除要求靠近固定支架安装外,仍要求每个固定支架间距内设三个导向支架。
               无约束型膨胀节可应用管道的架空、地沟敷设,也可应用于有补偿的直埋敷设,此时补偿器处应设检查井或暗室。
            注:如需法兰连接按照JB-59标准供货,也可根据用户要求或其它标准供货。参数中长度为接管连接式长度,如法兰连接长度略长。
            用途
              “无约束”是因以往的轴向型补偿器(波纹管)对使用有较多约束条件得名的。无约束型膨胀节完全消除了以往轴向型补偿器对导向支架间距的L1≤4D,L≤14D和L3的要求。鑫科生产的无约束型膨胀节已实现了管架间距“无约束”的最后目标。无约束型膨胀节不仅具有柱状稳定性,还具有自导向能力。所以无约束型膨胀节完全消除 4D、14D、L3的约束,克服安装误差,体积小,安全可靠的特点,可以消除以往轴向型补偿器易发生的扭弯和失稳等常见病,并对管道保温也带来了很大的方便。
