Layout of steam pipes
Thread Content
May I ask, in terms of the layout of steam pipes, which of the following methods is more reasonable? A stop valve is installed on the bypass pipe and is not used under normal circumstances. The main pipeline is controlled for on/off operation using a pneumatic ball valve. Is the bypass pipe on top or at the bottom?
The bypass pipe is usually on top; in special cases, it is at the bottom. Operational convenience is the main consideration
Why does it have to be up and down? Can’t it be left and right?
Steam flow meters generally do not have bypasses
Then the bypass pipe can also be placed below. In our factory, the control units are located on the pipe racks, while the bypass pipes are placed on the ground; this also allows them to serve as drains at the lowest point
Economics and operability were overlooked
The bypass is at the bottom; under normal operation the stop valve is closed. There is condensate on both sides of the stop valve, so 2 steam traps are required.
