What is the main difference between atmospheric pressure vessels and pressure vessels?
Atmospheric pressure vessels cannot withstand pressure; from a structural perspective, such vessels also have elliptical end caps at both ends. What else?
There are some small tanks like this, which generally have a slight positive pressure
JB/T4735-1997 has been replaced by NB/T 47003.1-2009...
Atmospheric pressure vessels are cheaper to manufacture, and they do not require such high standards for the skills of welders. ;P
The pressures are different. Pressure vessels with an operating pressure of ≥0.1 MPa are considered pressure vessels, while those with a pressure ranging from -0.02 to 0.1 MPa are considered atmospheric pressure vessels.
The hazards that occur in an accident vary
The pressure is different; only pressures greater than 0.1 MPa can be considered pressure vessels
It is defined in accordance with the requirements specified in the \"TSG_R0004-2009 Safety Technical Inspection Regulations for Fixed Pressure Vessels\", based on the following three conditions: 1. The operating pressure is greater than 0.1 MPa; 2. The product of the vessel’s volume and its operating pressure is greater than or equal to 2.5 MPa·L； 3. Operating temperature: When the medium inside the container is a liquid whose maximum operating temperature is below its standard boiling point. When both conditions are met, it shall be controlled as a pressure vessel.
What is the difference between atmospheric pressure vessels and non-tank containers? Neither of them falls under the regulations regarding vessels
At normal pressure, the container can be operated with its opening exposed, such as without a lid. The cover manhole is open. Pressure vessels must be sealed while in operation
