What type of valve is suitable for temperatures of 800 degrees?
Thread Content
DN15 is connected to precision steel pipes with an outer diameter of 16mm, using bayonet connectors at both ends； DN32 refers to precision steel pipes with an outer diameter of 30mm, connected at both ends using clamp-type fittings ； The operating temperature requirement is long-term tolerance to high temperatures of 800 degrees, with high-temperature air as the medium ； Pressure resistance of 5 kilograms. A ball valve is used, requiring a compact structure; electric control is the preferred method for operation. This is a requirement from the client; I would like to ask everyone how we should handle this?
Are you from a valve factory or something? You’ve asked such a detailed question about this! Use 316 material for the valves, and apply treatments to ensure high-temperature elongation and prevent sticking (to avoid the impact of high temperatures on the operation of the actuators as well as sticking due to high temperatures). For the connections at the flow path where the pressure is 0.5 MPa, wouldn’t it be better to use blind flanges with threaded inserts?
It seems the poster is a equipment supplier, while you are in the engineering field. Your way of speaking is exactly the same as that of the several specialists in our company’s construction management department.
I’m sorry, sir; I work in valve manufacturing. I’m thinking that if the original poster works at a valve factory, asking this question is simply stupid::P
Sincerity is not a joke; it is admiration. I work in process engineering at the factory; there are often tasks related to technical upgrades, inspections, and maintenance. Sometimes I find these tasks difficult to handle, so I ask them for help. And then they take a look… and it turns out that everything is actually very simple. Then I’ll say again, because of this, it’s possible that this will happen; doing it this way will result in that. It’s still the same: it’s okay, just stay like that; that’s fine, it’s simple! Then I instructed the mechanics to get to work, and it was taken care of. I truly admire it. Maybe I’m really not good at this; our supervisor always says that “I think things through quite carefully and have a solid theoretical foundation, but I just lack practical construction experience.””
You’re being too kind. Next time there are issues with valves, we can exchange ideas and learn from each other*:handshake
