***Anti-expansion measures must be taken in case of big temperature difference:
A. In pipe vertical installation,the main pipes will expand & hrink in hot & cold conditions vertically between the two floors. One support (pipe buckle seat) shall be installed adjacent to two branches each.The distance between the supports shall not exceed 400mm,other means can also be used to compensate,e.g.,use the branch of the main pipe to compensate naturally.
B. Pipe network installed outside
(1).The places where pipe network direction changes can be used to compensate linear expansion.In special case. U loop can be used to compensate the expansion,mainly for Φ50-110mm pipes.Altention must paid to split the pipe into several sections when anchoring piece is installed and expansion force can be oriented to the direction needed.
(2).For Φ20-50mm pipe,mechanic binding method can used to prevent expansion.
C. Hidden pipe layout
The pipe embedded into walls and floors can prevent expansion,the decoration must be done with the materials capable to absorb pressure and elongation force without being damaged.In case there is partition materials(meet with standard)in the pipe,the materials shall tolerate more expansion.The outer diameter of the pipes shall not exceed Φ25mm. Note:When operation temperature is below 5ºC,heating time shall be extended by 50%.
