求翻译：当层高H小4m时，立管上每层应设伸缩节一个，层高H大于或等于4m时，应依据计算确定；悬吊管设置伸缩节应结合支撑情况确定，悬吊横直管上伸缩节之间的最大间距不宜超4m，超过4m时，应依据管道设计伸缩量和伸缩节最大允许的伸缩量计算确定。是什么意思？

When H -storey hours 4m, expansion joints should be located on each floor one storey H is greater than or equal to 4m on the riser , should determine the basis for calculating ; hangers set expansion joints should be combined with support determined , hanging straight horizontal pipe

When storey H small 4M, at each layer should be the telescopic section A, storey H greater than or equal to 4 M, should be based on calculations used to determine; suspension tube set telescoping sections should be combined with support, suspended three steps by three steps on the telescoping sectio
