The definition and origin of pressure vessel nozzle
Thread Content
Does anyone know the definition and source of pressure vessel takeover?
definition: Pressure vessel nozzles are metal pipes used to transport media, including steam, liquid, etc., that can establish or maintain pressure. Source: "Standard for Risk Assessment of Pressure Vessel Takeovers" (PO-341-R-0), American Petroleum Institute, July 2011. -
No one can answer it? Explanation in GB.
I really haven't found what you're talking about. First of all, let me tell you that the takeover refers to the connecting steel pipe. Secondly, the question you asked is too professional, but this is only based on the rigor of laws and regulations. Thirdly, the question you asked is too unprofessional, because no one would think about how to define this kind of thing. Finally, there are many places where the lack of definitions can lead to deviations in understanding or even contradictions. This was something that experts did not take into consideration at the time. The standard drafting group was also divided into a professional group and a legal group. The two sides often argued with each other, but in the end a balance was found in the middle.
There is no problem in the professional group's reference to other standards. However, the legal and regulatory systems of other countries are very different from our country's situation, and the legal group cannot pass it. In the end, it is in line with our country's national conditions and is in line with our country's national conditions. This can easily lead to widely different standards.
You don’t need to understand the difference in depth between [boiler] [pressure vessel] [pressure pipe] [gas cylinder]. There is no strict boundary between them. The gas cylinder itself is a pressure vessel, the boiler itself may be a boiler or a pressure vessel, and the pressure vessel may also be made of pressure pipes.
