1、(word完整版)管道补偿量计算补偿器的正确安装和管道补偿量的计算方式发布日期：201007-08 一般情况下允许不装补偿器的直管段最大长度民用建筑为33m，工业建筑为42m。（管道伸长量分别为40mm和50mm）。能进行自然补偿部分管道确定了，其余部分就是应该设置补偿器的部分。计算这部分伸长量，如果较长要设置多个补偿器,应注意均匀设置；并在两个补偿器中间设置固定支架.选择时注意套筒补偿器容易漏水漏气，适合安装在地沟内，不适宜安装在建筑物上部;波纹管补偿器能力大耐腐蚀,但造价高并且需要设置导向支架；方形补偿器需要的安装空间较大,但运行可靠应用广泛.设计时可以根据工程具体情况选用。管道的热伸长量
