Regarding steam pipe branches
Thread Content
Generally, when branching off from a steam main, it is required to do so from the top of the main, with the isolation valve arranged horizontally and close to the branching point. But do the branches of the branch need to be like this as well? In confusion. Similar problems exist with other utility pipes as well. Thank you all for your answers. There is another special case: after steam pipe A, which branches off from the main corridor, enters the partition, its elevation drops. If branch B is then introduced from the top, wouldn’t this result in a liquid pocket forming in pipe A? Hydrophobization also needs to be applied; if it is led out from the bottom, condensate drainage or hydrophobization at branch B can be used to handle it.

The branches of a branch are the same in this regard, but whether to include valves or not depends on the specific circumstances.
The pipes leading to the valves should be reduced to prevent the accumulation of liquid.
The steam branch pipes generally have their nozzles pointing upward to prevent water from accumulating
First of all, it should be understood that the steam line branches emerge from above, and valves are installed on the horizontal sections near the main pipe in order to prevent water accumulation in the main pipe from flowing into the branches; naturally, the same approach must be adopted for the branches of those branches as well. For other utility pipelines, the same analysis method is applied; for example, for gas pipelines such as air lines and nitrogen lines, the branch pipes are also led out from above ； For liquid pipelines such as condensate pipes and steam line traps, on the contrary, branch pipes must be led out from below the main pipe.
