Steam retaining ring for hydrogenation unit flanges
Thread Content
In bk14.jpg, during the study session, it was observed that some flanges had a retaining ring; the other end of this ring was connected to steam, while some flanges did not have such a ring. May I ask what function this retaining ring serves? Where is it used?
You mean the steam protection ring, right? Inlet and outlet of the furnace, inlet and outlet of the reactor – these are usually present~~~
These steam rings generally appear on the reverser head cover and the flange surfaces of the heat exchangers in the hydrogen-related systems; they should serve to provide protection and isolation in the event of leaks
You are referring to the steam curtain, which is installed in those areas where there is a risk of fire in case of a leak of the medium within the equipment pipelines. Its main function is to provide fire protection; the control valves are usually placed away from the steam curtain, so that it can be activated promptly in order to extinguish the fire in case of a leak.
Teacher, if the flange isn’t leaking, is it still necessary to add something?
This is a security measure; in other words, it’s a preventive measure, so it needs to be installed regardless of whether there’s a risk or not.
Where exactly should it be added mainly?
Where exactly should it be added mainly?
For example, the reactor inlet and outlet, the outlet of the hot high-pressure gas phase, the inlet and outlet of the hydrogen-blended heating furnace in front of the furnace, etc. In short, installations should be added at all locations where a fire might occur in the event of an oil and gas leak.
Are you referring to the fire-extinguishing steam ring? This is mainly used to isolate and extinguish fires in the event of a leak in the flange of the hydrogenation reactor
