Can several drain pipes from steam traps be connected to a single main pipe?
Sure, no problem. . . . . . .
Sure, but it is required that the supervisor ensures there is no pressure
This centralized water supply is quite common. It is generally required that the condensate water connect to the main pipe at a 45-degree angle from the upper part of the main pipe (tilted backward in the direction of flow), and the condensate pipeline should be made thicker. During operation, it is necessary to avoid excessive steam leakage from individual traps, as this could affect other traps. Especially when the pressure ratings of the heat tracing steam are different. There should be a shut-off valve behind each trap, and a check valve in front of the shut-off valve, so that the drainage performance of each trap can be checked individually. It's better to have a one-way valve.
When there is a large difference in the outlet water temperature, it is best to route them separately; otherwise, water hammer will occur
It’s okay to have back pressure, as long as it does not exceed the steam pressure, and the steam trap is suitable for operating in an environment with back pressure – for example, a free-floating ball steam trap
Refer to SH/T 3040-2012 Code for Design of Pipelines Accompanying and Jacketed Pipelines in Petrochemical Industries.
No problem, just consolidate it into the main return pipeline
In theory, it should be possible, but there’s a risk that one or more of the components might not function properly, leading to water hammer in the main pipeline; we’re currently facing exactly this issue
