Is the equipment code for pressure vessels determined during the design phase?
Thread Content
Is the equipment code for pressure vessels determined during the design phase? Is it the market supervision bureau that issues it only during the manufacturing stage? For example, 2105XXXXXXXXXX
The equipment code for pressure vessels is assigned by the market supervision authority during the manufacturing process, based on the design documents and relevant standards, rather than being determined at the design stage. The equipment code is the unique identifier of a pressure vessel; for example, 2105XXXXXXXXXX indicates information such as the manufacturer, model, and material of the vessel. These details need to be approved prior to manufacturing to ensure compliance with **standards and safety requirements. .
It shouldn’t be; it’s similar to an ID card, I guess
The device code can be finalized only when the manufacturing unit prepares the process documents. Code composition: It consists of a total of 18 digits, including the device’s basic code, the manufacturer’s code, the year of manufacture, and the serial number.
Compiled by the manufacturer in accordance with TSG 21—2016; see Appendix D: Coding Method for Special Equipment
1. Prepared by the manufacturer in accordance with Appendix D of TSG 21-2016, and released from the factory after supervision and inspection by a testing institution； 2. If there is no equipment code, it shall be prepared by the registration authority in accordance with Appendix D of TSG 21-2016, wherein the manufacturer’s code is replaced by the administrative division code of the registration authority (one digit more than the manufacturer’s code).
During the design phase, the design institute only provides the equipment tag numbers.
The tag number is provided by the unit’s process department; what does it have to do with the design team?
What he referred to was the tag number during the overall system design prior to construction； This is usually done by the general contractor.
Tag numbers are terms used in process engineering; they are not formal terms. Tag numbers are not unique and are not used as positioning identifiers for equipment. Generally, the tag numbers are assigned by the process design team or the user unit, and they change as the process is modified. This falls outside the scope of work for the design firm.
