(5)The diameter of the pipes should be suitable.

seams inside the sleeve. The steel sleeve should keep flush with floor, or 20mm above
the floor for the floor-thru pipes. The steel sleeve is not allowed to affect the slope of the
pipe and can't be used as the support of the pipe. Clearance between the pipe and the
sleeve should be stuffed by flexible non-inflammable material.
