Thread Content
Although the operation is at atmospheric pressure, it should be classified as special equipment. The company is now planning to start production; we need to know where to file the relevant registrations and what documents are required.
According to the standards for towers, when the internal pressure is below 1 kilogram, the design pressure is set at above 1 kilogram; in other words, it is necessary to classify the vessel as a specific type of container. At least contact the provincial or municipal authorities to obtain a pressure vessel manufacturing license.
First, obtain the container manufacturing license, and then proceed with the registration process
Since it does not meet the application scope of 1.3 in the fixed capacity regulations, the tower mentioned by the poster does not fall into any category and is not subject to supervision and inspection. Find an experienced design firm, or if you have design experience yourself, you can handle the design.
