摘　　要：分析了高层住宅室外燃气立管补偿方法。方形补偿器和固定支架的数量均随穿墙套管内径增大而减少。设置波纹管补偿器时,相邻两个固定支架间的距离不应大于设定立管长度。设置方形补偿器时,相邻两个固定支架间的距离不应大于2倍设定立管长度。相同工况下,波纹管补偿器安装数量比方形补偿器增加约1倍。The compensation method for outdoor gas riser in high-rise residential buildings is analyzed.The numbers of square compensators and fixed brackets decrease with the increase of the inner diameter of the wall penetrating sleeve.When setting up a bellows compensator,the distance between adjacent fixed brackets should not exceed the set length of the riser.When setting up a square compensator,the distance between adjacent fixed brackets should not exceed twice the set length of the riser.Under the same working conditions,the number of bellows compensators installed is about twice that of square compensators.
