Pressure vessel nameplate
Thread Content
The nameplates of the pressure vessels currently in use in our company follow the format specified in the \"Regulations on Pressure Vessels\", but the inspection authorities believe that the address of the manufacturing unit should be added below. Is there such a requirement? Please advise; thank you!
There isn’t any, right? Our company has never had this before; it has passed the inspections anyway. But they want you to add it, and it’s fine to do so – after all, they are in a position of authority
It's needed. If the address of the production unit changes, it needs to be re-reviewed. If you don’t specify the production address, does it then not matter if the address changes?
Although it’s not specified in the tolerance standards, it must be included according to the inspection requirements, as inspections are carried out on-site
There’s no need for that; it’s not specified in the standards either. We only have the company name, not an address
You can include the address of the production unit, as well as contact information – that makes things easier for people!
The manufacturing unit must install a product nameplate in a visible location on the pressure vessel; the nameplate shall at least indicate: the name of the manufacturing unit, the manufacturing license number, the category of the pressure vessel, the date of manufacture, the name of the pressure vessel, the product number, the design pressure, the design temperature, the maximum operating pressure, the maximum allowable operating pressure (if applicable), the net weight of the pressure vessel, and the inspection mark. It didn’t state that the manufacturer’s address was required. This post was last edited by zhangyong6404 on 2009-4-15 18:25.]
So what should be done in this situation? The company A where I used to work specialized in manufacturing stainless steel vessels under normal pressure; it did not have the necessary qualifications for producing pressure vessels. Later, it acquired a manufacturer B that did have such qualifications, retained its quality assurance system, employees, and processing equipment, but changed its name and legal entity to its own, thus turning into one company. This company has two factories in different locations (both in Shanghai). If the address of the manufacturer is not specified, can Company A still produce pressure vessels?
The tolerance specifications specify requirements for the nameplate. But not limited to the specified items. Many manufacturers have their own format for nameplates, and many users, especially large ones, specify their own style for nameplates. However, the items listed on one’s own nameplate must not lack those specified by the tolerance standards. Therefore, it is not in violation of the regulations for the inspection department to request an addition. If you wish, you can add more items as well.
The format of the nameplate as specified in the tolerance standards is also recommended; there is no mandatory requirement to follow it, but the tolerance standards do require that certain information be included on the nameplate. Our inspection personnel also insist that the address be included, presumably due to relevant regulations – otherwise, many places across the country would not adopt this practice.
Article 53 of the “Requirements for Licensing the Manufacturing of Boilers and Pressure Vessels”: Metal nameplates shall be installed in a prominent position on pressure vessels. The items on the nameplate should include at least the following (expressed in Chinese or English, using the International System of Units): (1) Product name ； (II) Name and address of the manufacturing enterprise ； (III) Certificate number of the manufacturing enterprise ； (IV) Medium name ； (5) Design temperature ； (VI) Design pressure ； (7) Voltage withstanding test pressure ； (8) Product Number ； (IX) Manufacturing date ； (X) Container category ； (11) Volume.

If it’s not specified in the standards, then it’s not mandatory; so there’s no need for it
The new regulations should be implemented soon. Revised approach for Chapter 4: Manufacturing – Regarding the documentation provided at delivery, the original requirements for such documentation are intended to be retained, but the specific formatting requirements for quality certification documents in the attachments have been removed; only the formatting requirements for nameplates and product certificates (product data sheets) remain. Moreover, the tolerance specifications represent the minimum requirements, which are mandatory and apply to manufacturing units across the country. It is also possible that local regulations may have requirements that are stricter than those set by standards
