(2)Insulating: PEF (δ=30mm) is taken as the insulating material.
1) The insulation should be arranged evenly and smoothly.
2) Flanges should be insulated separately.
3) Seams of the insulation should be airproof.
4) Insulation for the stainless iron sheet should be smoothly and the seams should be
airproof.
5) Flanges should be insulated separately.
6) Seams of the iron sheet should be at the downstream of the drain water.
(3)Note: for the riser pipes, when the floor height is or less than 5m, there should be a brack-
et tray for each floor; when the floor height is larger than 5m, there should be at least two
bracket trays 200mm ahead of the riser pipes. The diameter of the bracket tray can't be
larger than the thickness of the insulation. Expansion seams should be left for the insula-
tion of the brackets. A 5mm expansion seam should be left every 5-7m on the branch
pipes. Also 30mm seams should be left for elbows. Clearance between the insulation and
the pipe sleeve should be stuffed with non-inflammable material.
(4)Pipes should be labeled with legible fonts and the direction of the fluid. The paint color
should be selected properly. Once color circles are used, their intervals should be even.
Labels listed in parallel should be arranged reasonably.
