Large-diameter pipe spacing
Thread Content
For large-sized pipes like the DN700, what is the distance from the center of the pipe to the wall, and also the distance from it to pipes of other sizes?
Following the specifications, there’s nothing special about it; it’s just like small pipes
Is there a specific regulation regarding how much it is? I’ve seen that some specifications include tables for pipe spacing, but the values go up to only 500; therefore I’m wondering what the requirements are for 700?
Are you in design or construction? If it’s construction, just find a designer
I don’t know what specifications you are referring to; according to 50316, the clear distance required is no less than 50 mm, so that they do not come into contact after thermal expansion and contraction.
The clear distance between pipe walls should be no less than 50 mm; however, the distance from protruding parts such as flanged valves to the adjacent pipe walls also needs to be taken into account. In the case of heat pipes, the thermal displacement distance must be considered as well.
The required clear distance between pipes and building walls in the petrochemical industry is over 100 mm; in addition, it is necessary to take into account the expansion of heat pipes, as mentioned on floor 6
