Fixed Pressure Vessel Data Sheet
Thread Content
What should be entered for the equipment type in the product data sheet of fixed pressure vessels? There are two ways to fill in the information: one is to do so based on the functional role of the container, such as reaction containers or storage containers; the other is to fill it in according to the catalog of special equipment, by specifying first-class pressure vessels, second-class pressure vessels, and third-class pressure vessels.
TSG R0004-2009 \"Regulations on Safety Technical Inspection of Fixed Pressure Vessels\", Appendix A3, Classification of Pressure Vessel Types – the term \"type\" is used here. It is divided into reaction, separation, storage, and heat exchange. However, in TSG 21-2016 \"Code for Safety Inspection of Fixed Pressure Vessels\", Appendix A4, Classification by Purpose, the term \"type\" has been removed. And in the catalog of special equipment, the term “variety” is explicitly mentioned. Based on this, I personally believe that it should be filled in as: Class 1 pressure vessels, Class 2 pressure vessels, Class 3 pressure vessels.
Of course, filling in “Category 1 pressure vessels”, “Category 2 pressure vessels”, and “Category 3 pressure vessels” seems unreasonable to me; it’s repetitive, as there is another field below for entering the equipment code. By using the equipment codes 2130, 2150, and 2170, it’s possible to determine the type of pressure vessel quite easily.
Did you fill out Category 1, Category 2, or Category 3?
Did you fill out Category 1, Category 2, or Category 3? The changes in the data sheet according to the old and new fixed capacity regulations should be filled in this way.
Actually, for the category classification here: A4 – Purpose classification. Pressure vessels are classified into reaction pressure vessels, heat exchange pressure vessels, separation pressure vessels, and storage pressure vessels, based on their functional principles in the production process. The specific classifications are as follows: (1) Reaction pressure vessels (code R), which are primarily used to carry out physical and chemical reactions of substances, such as various reactors, reaction kettles, polymerization reactors, synthesis towers, shift converters, gas generators, etc ； (2) Heat exchange pressure vessels (code E) are primarily used for facilitating heat exchange of fluids, such as various heat exchangers, coolers, condensers, evaporators, etc ； (3) Separation pressure vessels (code S) are primarily used for achieving fluid pressure balance and buffering, as well as for the purification and separation of gases; examples include various separators, filters, oil collectors, washers, absorption towers, copper washing towers, drying towers, stripping towers, steam generators, and deaerators ； (4) Storage pressure vessels (code C, with spherical tanks coded as B) are primarily pressure vessels used for storing or holding gases, liquids, liquefied gases, and other such media, such as storage tanks of various types. In a pressure vessel, when it possesses two or more process principles simultaneously, it should be classified according to the primary function within the process.
You can find this table further up; for example, those who are more particular will fill in ‘ILC category – low-pressure storage container’.
I agree with your view; it expresses three meanings: category + pressure level + container code
