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 be-tween adjacent fixed brackets should not exceed twice the set length of the riser.Under the same working conditions,the number of bellows compensators in-stalled is about twice that of square compensators.
