Purging of steam and condensate pipelines
Thread Content
Can steam pipelines of different pressure grades and the corresponding condensate pipelines be purged together
It is not allowed for the pipelines to be connected to each other during simultaneous purging, to prevent cross-contamination!
There should be no problem; the work pressure is at the same level, and the purging is usually done in an open area! Fittings such as traps must be removed.
It is recommended not to purge together; instead, purge separately to prevent the occurrence of scattered particles everywhere, and to ensure thorough cleaning. The same gas source can be used for purging.
3# ghyjy2009: The pressure of both steam and condensate is 6 kilograms, and miscellaneous air is used for purging.
It is best not to purge together; it is recommended to carry out the process in stages by separating the sections. This allows for the effective removal of impurities from within the pipelines, while also preventing blockages in valves and traps
It is certain that they cannot be purged together! If that’s the case, high-pressure steam will mix with low-pressure steam.
It must be purged in the order from high pressure to low pressure
Purging is simply used to clean the pipes (such as removing slag, etc.), and it’s sufficient to follow the required operating procedures!
