Does anyone know if this heat exchanger is a pressure vessel?

The information you provided is incomplete and there should be some media. No matter what, it already meets the specifications of a pressure vessel and should be classified as a pressure vessel.

Not only is there a lack of media, but there is also a lack of shell diameter and size, making it difficult to judge, but I believe my peers (designers) will not make a mistake.

The medium information is incomplete, but it can be initially determined to be a pressure vessel.

The pipe pressure is 32MPa and the temperature is 160 degrees. It should be a pressure vessel. However, can the heat exchange tubes withstand it?

First of all, to determine whether a pressure vessel is subject to inspection under the "Content Regulations", it must meet the three conditions stipulated in the "Content Regulations" at the same time. The conditions given by the poster are not enough and it is impossible to judge. The equipment diameter, volume, state of the medium and other conditions must also be met. Now that the manufacturing unit's certificate has been signed, I think the most important thing is to check the design unit's drawings. The design unit's drawings shall prevail. As long as there is no problem with the design unit's qualifications, then you can fully trust the design unit.

Pressure vessels refer to closed equipment that holds gas or liquid and carries a certain pressure. Its scope is defined as fixed containers and mobile containers for gases, liquefied gases, and liquids with a maximum working temperature higher than or equal to the standard boiling point, with a maximum working pressure greater than or equal to 0.1MPa (gauge pressure), and the product of pressure and volume greater than or equal to 2.5 MPa·L.； Cylinders containing gases, liquefied gases and liquids with a standard boiling point equal to or lower than 60°C whose nominal working pressure is greater than or equal to 0.2 MPa (gauge pressure), and the product of pressure and volume is greater than or equal to 1.0 MPa·L ； Oxygen chamber, etc.

Any closed container containing pressure medium can be called a pressure vessel. Those subject to the supervision of the "Capacity Regulations" should be called compliance pressure vessels, and those subject to the jurisdiction of GB150 are called GB150 pressure vessels. This should be distinguished.

The pipe pressure is 32MPa and the temperature is 160 degrees. It is probably a pressure vessel.

A shell and tube heat exchanger with a tube side pressure of 32MPa, a temperature of 160 degrees, and molten salt as the medium? . The shell side pressure level is 0.6MPa, the temperature is 60 degrees, and the medium is water? . The heat exchange tube is a stainless steel tube with a diameter of 25mm and a thickness of 4mm. The diameter of the shell is 108mm. Such a thing is indeed not a pressure vessel.

Not necessarily, it also depends on the container volume and diameter.

I don’t know whether the tube-side fluid of the heat exchanger is a liquid or a gas. If it is a gas, it must be classified. If it is a liquid, buy medicine to check the boiling point. If the temperature of 160 exceeds the boiling point of the medium, it belongs to supervision and management. If there is no external container, it does not belong to the category.

It also depends on the nominal diameter of the equipment. If the diameter is too small and cannot meet the requirements of the regulations, it is also classified as an external container.

It is mainly determined based on the characteristics of the medium, boiling point under standard conditions, weather space and size and equipment selection, and based on the planning conditions of the "Capacity Plan".

1. Pressure vessel: It is mainly divided into storage and transportation vessels, reaction vessels, heat exchange vessels and separation vessels. 　2. There are many ways to classify pressure vessels. From the perspectives of use, manufacturing and supervisory inspection, there are the following categories. 　　(1) According to the level of pressure, it is divided into: Low pressure vessels, medium pressure vessels, high pressure vessels and ultra high pressure vessels. 　　(2) According to the holding medium, it is divided into: Non-flammable and non-toxic ； Flammable or toxic ； Highly toxic. 　　(3) According to different functions in the process, it is divided into: 　　①reaction vessel: A container used to complete physical and chemical reactions of media. 　　②heat exchange container: A container used to complete the heat exchange of the medium. 　　③Separation container: Containers used to complete mass exchange of media, gas purification, and solid, liquid, and gas separation. 　　④Storage and transportation container: A container used to hold liquid or gaseous materials, storage and transportation media, or to balance and buffer pressure.

It depends on the medium passing through the heat exchanger. Just refer to the capacity gauge for the identification method!

The initial judgment is that it should be a pressure vessel. The manufacturer may not have the manufacturing qualifications to say so.

Thanks, everyone. The tube side is hydrogen nitrogen. The shell side diameter is 250mm, and the medium is water.

Merely having diameter is not enough^_^ The host needs to study hard * Various regulations, how to judge whether the equipment is a pressure vessel! PS: How to calculate the volume?^_^, think about it~~~

Whether it is a pressure vessel cannot be judged solely by the conditions provided by the original poster. That is, the pressure, volume, and medium must meet three conditions at the same time. The classification of vessels is based on the design pressure according to the requirements of the Capacity Regulations. The pressure used to determine whether a vessel is subject to supervision by the Capacity Regulations is the maximum working pressure. The applicable scope of GB150 is determined according to the design pressure, and the supervision scope of the Capacity Regulations is based on the maximum working pressure. The two are not unified. Therefore, sometimes pressure vessels may be designed and manufactured in accordance with GB150, but they do not need to be inspected, which means they are "unsupervised pressure vessels."

Pressure vessels refer to closed equipment that contains gas or liquid and carries a certain pressure. Its scope is defined as fixed containers and mobile containers for gases, liquefied gases, and liquids with a maximum working temperature higher than or equal to the standard boiling point. The maximum working pressure is greater than or equal to 0.1MPa (gauge pressure), and the product of pressure and volume is greater than or equal to 2.5MPa·L.； Cylinders containing gases, liquefied gases and liquids with a standard boiling point equal to or lower than 60°C with a nominal working pressure greater than or equal to 0.2MPa (gauge pressure) and the product of pressure and volume greater than or equal to 1.0MPa·L ； Oxygen chamber, etc. (Selected from the "Special Equipment Safety Supervision Regulations") 1. This regulation applies to pressure vessels that meet the following conditions: 1. The maximum working pressure Pw Note 1. is greater than or equal to 0.1Mpa (excluding hydrostatic pressure, the same below); 2. The inner diameter (non-He-shaped cross-section refers to its maximum size) is greater than or equal to 0.15m, and the volume (V) (Note 2) is greater than or equal to 0.25m3; 3. The contained medium is gas liquefied gas or a liquid with a maximum working temperature higher than or equal to the standard boiling point (selected from the "Safety Technical Supervision Regulations for Pressure Vessels"). It is directly related to the volume. The data provided by the poster is not comprehensive enough and cannot be directly judged!
