Do heat transfer oil pipelines belong to pressure pipelines?

Do heat transfer oil pipelines belong to pressure pipelines? Be regulated by the Market Supervision Bureau? But a reactor jacket filled with heat transfer oil isn’t considered a pressure vessel, right?
Heat transfer oil pipelines belong to the pipeline system, not pressure vessels. Its safety needs to be supervised by the relevant departments of the market supervision authority. When heat transfer oil is circulated through the jacket of the reactor, it constitutes an auxiliary device and is not considered a pressure vessel; nevertheless, it still needs to comply with safety regulations and relevant oversight requirements. .
Heat transfer oil pipelines are considered pressure pipelines, as heat transfer oil is a Class C medium.
Why do people keep asking such questions? First, you need to provide all the parameters: operating pressure, operating temperature, volume, and nominal pipe diameter
For a 5000L reactor, the inner cylinder operates at atmospheric pressure, while the jacket is fed with heat transfer oil at a pressure of 4 kilograms and a temperature of 300°C. What about this setup? Is it a pressure vessel?
The heat transfer oil reactor you mentioned, based on the current parameters, does not fall under the category of pressure vessels; many parameters are still missing. Moreover, pressure vessels are not the same as pressure pipelines. To determine whether it is a special equipment, it is necessary to refer to the \"Catalogue of Special Equipment\" based on the actual circumstances.
A reaction kettle is a multi-chamber container; the inner cylinder and the jacket need to be evaluated separately. If one of the chambers is considered a pressure vessel, then the entire equipment is classified as a pressure vessel. Assuming that the inner cylinder is at atmospheric pressure and therefore not a pressure-bearing component, the jacket is filled with 4 kg of heat transfer oil at 300°C; 1. The pressure requirements are met ； 2. Volume unknown ； 3. The medium is heat transfer oil. Similar to Freon, “heat transfer oil” is merely a generic term. If its volume meets the requirements and it reaches its standard boiling point at 300°C, then it is considered a pressure vessel. The opposite is not true.
It’s the last two that require you to make a judgment
If you can’t even understand this, then there’s nothing more to say; go and find a professional to give you on-site guidance
For a 5000L reactor, the inner cylinder operates at atmospheric pressure, while the jacket is fed with heat transfer oil at a pressure of 4 kilograms and a temperature of 300°C. What about this setup? Is it a pressure vessel? It’s a pressure vessel now. Go get the usage permit. The standard boiling point of dao-generated oil is 260 degrees Celsius. The jacket volume of the 5000L reactor exceeds 30 liters, and its diameter is greater than 150 mm. The pressure of 0.5 MPa is greater than 0.1 MPa.
Where was the standard boiling point of 260 obtained from? Are there any screenshots?
