What to do with the steam trap during steam pipeline purging
Thread Content
When purging steam pipes and heating them up, is it necessary to remove the drain valve? If it isn’t removed, could welding slag clog the drain valve? Even if the shut-off valve in front of the drain valve is closed, it’s still not possible to remove debris from that area. As for the specific procedures for purging steam pipes, what are they?
Should the steam pipes connected to the equipment be purged along with the equipment? It’s better to disconnect and blow separately
It shouldn’t be hard to remove it either; otherwise, welding slag getting stuck there would cause more trouble. It’s better to resolve it completely once and for all
1. Close the valve in front of the trap, vent it before the valve; remove the trap only after blocking it. 2. Generally, the flanges are removed before the equipment is introduced; after purging is complete, the upper parts are installed, and then the equipment is moved backward for further purging.
It’s better to disassemble it in advance, so as to avoid having to take apart the strainer for cleaning later. ---------------------------
If it’s removed, how will the condensate water during purging be discharged? It will also be difficult to get rid of the large amount of water generated when heating the pipes
Through the bypass valve of the strainer, or the drain valve.
How to provide safety protection when disconnecting pipelines near equipment?
The pipes on the equipment have been removed – how should safety measures be implemented?
Many traps on the pipeline lack bypass valves as well as drain valves :(
After removing the trap, install a valve temporarily.
